Celebrated almost exclusively in [[Ecclesiastical Latin]], it was the most widely used [[Eucharist]]ic liturgy in the world from its issuance in 1570 until its replacement by the [[Mass of Paul VI]] promulgated in 1969 (with the revised Roman Missal appearing in 1970).<ref>{{Cite web|url=https://www.catholicculture.org/culture/library/view.cfm?recnum=2786|title=Library : Liturgical Languages|website=www.catholicculture.org}}</ref>

"Tridentine" is derived from the Latin {{lang|la|Tridentinus}}, {{lit|relating to the city of [[Trento|Trent]]}}, where the [[Council of Trent]] was held at the height of the [[Counter-Reformation]]. In response to a decision of that council,<ref>{{Cite web|url=https://history.hanover.edu/texts/trent/ct25.html|title=CT25|website=history.hanover.edu}}</ref> [[Pope Pius V]] promulgated the 1570 Roman Missal, making it mandatory throughout the [[Latin Church]], except in places and [[Religious order (Catholic)|religious order]]s with rites or uses from before 1370.{{efn|name=theseregions}}  

[[Preconciliar rites after the Second Vatican Council|Permissions for celebrating the Tridentine Mass]] have been adjusted by successive popes, and most recently restricted by [[Pope Francis]]'s ''motu proprio'' ''[[Traditionis custodes]]'' in 2021.<ref name="Traditionis custodes">{{Cite web |author=[[Pope Francis]] |date=16 July 2021 |title=Apostolic Letter issued "Motu proprio" by the Supreme Pontiff Francis "Traditionis custodes" on the use of the Roman Liturgy prior to the Reform of 1970, 16 July 2021 |url=https://www.vatican.va/content/francesco/en/motu_proprio/documents/20210716-motu-proprio-traditionis-custodes.html |access-date=16 July 2021 |work=vatican.va |language= |quote= |location=Rome}}</ref> This has been controversial among [[traditionalist Catholics]].

==Terminology==
[[File:unchurch.jpg|thumb|right|A Roman Rite [[Catholic]] [[altar]] set up ready for a [[solemn mass]]. Leaning against the [[Church tabernacle|tabernacle]] and two of the candlesticks are [[altar cards]] (sometimes associated with the [[Tridentine]] manner of celebrating the Mass).]]
The term "Tridentine Mass" applies to celebrations in accordance with the successive editions of the [[Roman Missal]] whose title attribute them to the [[Council of Trent]] (''Missale Romanum ex decreto Sacrosancti Concilii Tridentini restitutum'') and to the pope or popes who made the revision represented in the edition in question. The first of these editions is that of 1570, in which the mention of the Council of Trent is followed by a reference to [[Pope Pius V]] (''Pii V Pont. Max. iussu editum'').<ref>Manlio Sodi, Achille Maria Triacca, ''Missale Romanum'', Editio Princeps (1570) (Libreria Editrice Vaticana 1998) {{ISBN|978-88-209-2547-5}}</ref> The last, that of 1962, mentions the popes only generically (''Missale Romanum ex decreto SS. Concilii Tridentini restitutum Summorum Pontificum cura recognitum''). Editions later than that of 1962 mention the [[Second Vatican Council]] instead of the Council of Trent, as in the 2002 edition: ''Missale Romanum ex decreto Sacrosancti Oecumenici Concilii Vaticani II instauratum auctoritati Pauli Pp. VI promulgatum Ioannis Pauli Pp. II cura recognitum''.<ref>{{Cite web|url=http://www.clerus.org/bibliaclerusonline/es/1d.htm|title=Sumario|website=www.clerus.org}}</ref>

Sometimes the term "Tridentine Mass" is applied restrictively to Masses in which the final 1962 edition of the Tridentine Roman Missal is used, the only edition still authorized, under certain conditions, as an extraordinary form of the Roman Rite Mass.<ref name="auto">{{Cite web|url=https://www.vatican.va/content/benedict-xvi/en/motu_proprio/documents/hf_ben-xvi_motu-proprio_20070707_summorum-pontificum.html|title=Motu Proprio Summorum Pontificum on the "Roman liturgy prior to the reform of 1970" (7 July 2007) &#124; BENEDICT XVI|website=www.vatican.va}}</ref>

Some speak of this form of Mass as "the Latin Mass". This too is a restrictive use of a term whose proper sense is wider. The Second Vatican Council Mass also has its normative text, from which vernacular translations are made, in [[Latin]], and, except at Masses scheduled by the ecclesiastical authorities to take place in the language of the people, it can everywhere be celebrated in Latin.<ref name="RS">{{cite web |author=Congregation for Divine Worship and the Discipline of the Sacrament |title=Redemptionis Sacramentum |date=2004-04-23 |url=https://www.vatican.va/roman_curia/congregations/ccdds/documents/rc_con_ccdds_doc_20040423_redemptionis-sacramentum_en.html |quote=Mass is celebrated either in Latin or in another language, provided that liturgical texts are used which have been approved according to the norm of law.

A few speak of the Tridentine Mass in general or of its 1962 form as the "[[Preconciliar rites after the Second Vatican Council|Gregorian Rite]]".<ref>{{cite news |url=https://www.telegraph.co.uk/news/uknews/2129070/Latin-mass-to-return-to-England-and-Wales.html |archive-url=https://ghostarchive.org/archive/20220112/https://www.telegraph.co.uk/news/uknews/2129070/Latin-mass-to-return-to-England-and-Wales.html |archive-date=2022-01-12 |url-access=subscription |url-status=live |title=Latin mass to return to England and Wales |newspaper=[[The Daily Telegraph]] |date=2008-06-14 |access-date=2008-06-17 |last= Thompson |first=Damian}}{{cbignore}}</ref> The term "Tridentine Rite" is also sometimes met with,<ref>[http://www.fordham.edu/halsall/basis/latinmass2.html Medieval Sourcebook]; [http://webarchive.loc.gov/all/20080212213620/http://www.catholicnews.com/data/stories/cns/0800689.htm Pope reformulates Tridentine rite's prayer for Jews]</ref> but [[Pope Benedict XVI]] declared it inappropriate to speak of the 1962 Roman Missal and that published by later popes as if they were two rites: rather, he wrote, it is a matter of "a twofold use of one and the same" Roman Rite.<ref name="extraordinaria"/> [[Hugh Somerville-Knapman]], O.S.B., says that they should be separate rites, as the Mass promulgated at the Council of Trent was already the pre-existing liturgy of the [[Diocese of Rome]] and has direct continuity with the Mass practiced by the apostles, whereas the changes made in implementing the [[Mass of Paul VI]] are so great that it no longer resembles any Catholic liturgy practiced prior to the 20th century.<ref>{{cite web |date=2019-04-04 |title=The strange birth of the Novus Ordo |website=Catholic Herald |url=https://thecatholicherald.com/the-strange-birth-of-the-novus-ordo |access-date=2021-06-19 |archive-url=https://web.archive.org/web/20250307014205/https://thecatholicherald.com/the-strange-birth-of-the-novus-ordo |archive-date=2025-03-07 |url-status=dead}}</ref>

Other names for the edition promulgated by [[Pope John XXIII]] in 1962 (the last to bear the indication ''ex decreto Sacrosancti Concilii Tridentini restitutum'') are the ''Extraordinary Form'', or the ''usus antiquior'' ("more ancient usage" in [[Ecclesiastical Latin|Latin]] ).<ref>{{Cite web |last=Hodge |first=Brendan |date=19 July 2021 |title=How extraordinary is the Extraordinary Form?

[[Traditionalist Catholics]], whose best-known characteristic is an attachment to the Tridentine Mass, frequently refer to it as the "Traditional Mass" or the "Traditional Latin Mass". They describe as a "codifying" of the form of the Mass the preparation of Pius V's edition of the Roman Missal, of which he said that the experts to whom he had entrusted the work collated the existing text with ancient manuscripts and writings, restored it to "the original form and rite of the holy Fathers" and further emended it.<ref name="QP">{{cite web |url = http://www.papalencyclicals.net/Pius05/p5quopri.htm |title = Quo primum |date = 14 July 1570 |access-date = 2008-03-25 |quote = We decided to entrust this work to learned men of our selection.

==Language==
In most countries, the language used for celebrating the Tridentine Mass was and is [[Latin]], which became the [[Ecclesiastical Latin|language of the Roman liturgy]] in the late 4th century. There have been some exceptions, primarily in missionary areas or for ancient churches with an established sacred-language tradition:<ref name="Gratsch1958">{{cite journal |author-last=Gratsch |author-first=Edward J. |title=The Language of the Roman Rite |journal=American Ecclesiastical Review |volume=139 |issue=4 |date=October 1958 |pages=255–260 |url=https://books.google.com/books?id=2MvNAAAAMAAJ&pg=PA255}}</ref><ref name=bonniwell>{{cite book |author-last=Bonniwell |author-first=William R. |title=A History of the Dominican Liturgy, 1215–1945 |edition=2nd |location=New York |publisher=Joseph F.

After the publication of the 1962 edition of the Roman Missal, the 1964 Instruction on implementing the [[Sacrosanctum Concilium|Constitution on Sacred Liturgy]] of the [[Second Vatican Council]] laid down that "normally the epistle and gospel from the Mass of the day shall be read in the [[vernacular]]".

Outside the [[Catholic Church|Roman Catholic Church]]:

* The vernacular language was introduced into the celebration of the Tridentine Mass by some European [[Old Catholic]]s (most [[Old Catholics]] use the Tridentine Mass, either in the vernacular or in Latin) and by Anglican [[Anglo-Catholic]]s (with the introduction of the ''[[English Missal]]'').

* Some [[Western Rite Orthodoxy|Western Rite Orthodox]] Christians, particularly in the [[Antiochian Orthodox Christian Archdiocese of North America]]'s [[Antiochian Western Rite Vicariate|Western Rite Vicariate]], use the Tridentine Mass in the vernacular with minor alterations under the title of the "Divine Liturgy of St. Gregory". Latin Masses on days of the week other than Sunday are becoming common.

== Pope Pius V's revision of the liturgy ==
At the time of the Council of Trent, the traditions preserved in printed and manuscript missals varied considerably, and standardization was sought both within individual dioceses and throughout the [[Latin West]]. Standardization was required also in order to prevent the introduction into the liturgy of Protestant ideas in the wake of the [[Protestant Reformation]].

Pope Pius V accordingly imposed uniformity by law in 1570 with the [[papal bull]] "''Quo primum''", ordering use of the Roman Missal as revised by him.<ref name="QP"/> He allowed only those rites that were at least 200 years old to survive the promulgation of his 1570 Missal. Several of the rites that remained in existence were progressively abandoned, though the [[Ambrosian rite]] survives in [[Milan]], Italy and neighbouring areas, stretching even into Switzerland, and the [[Mozarabic rite]] remains in use to a limited extent in [[Toledo, Spain|Toledo]] and [[Madrid]], Spain. The [[Carmelite]], [[Carthusian]] and [[Dominican Order|Dominican]] religious orders kept their rites, but in the second half of the 20th century two of these three chose to adopt the [[Roman Rite]]. The rite of [[Braga]], in northern Portugal, seems to have been practically abandoned: since 18 November 1971 that archdiocese authorizes its use only on an optional basis.<ref>{{Cite web |url=http://apostolicos.en.telepolis.com/9-BRAGA_(Portugal).html |title=Braga – Capital de Distrito |access-date=2006-12-27 |archive-date=2006-09-16 |archive-url=https://web.archive.org/web/20060916182317/http://apostolicos.en.telepolis.com/9-BRAGA_%28Portugal%29.html |url-status=dead }}</ref>

Beginning in the late 17th century, France and neighbouring areas, such as [[Münster]], [[Cologne]] and [[Trier]] in Germany, saw a flurry of independent missals published by bishops influenced by [[Jansenism]] and [[Gallicanism]]. This ended when [[Abbot Guéranger]] and others initiated in the 19th century a campaign to return to the Roman Missal.

Pius V's revision of the liturgy had as one of its declared aims the restoration of the Roman Missal "to the original form and rite of the holy Fathers".<ref name="QP"/> Due to the relatively limited resources available to his scholars, this aim was in fact not realised.<ref>"Just after the Council of Trent, the study 'of ancient manuscripts in the Vatican library and elsewhere', as Saint Pius V attests in the Apostolic Constitution ''Quo primum'', helped greatly in the correction of the Roman Missal. Since then, however, other ancient sources have been discovered and published and liturgical formularies of the Eastern Church have been studied. Accordingly, many have had the desire for these doctrinal and spiritual riches not to be stored away in the dark, but to be put into use for the enlightenment of the mind of Christians and for the nurture of their spirit" ([http://www.catholic-forum.com/saints/pope0262r.htm Apostolic Constitution ''Missale Romanum''] {{webarchive |url=https://web.archive.org/web/20121101124024/http://www.catholic-forum.com/saints/pope0262r.htm |date=2012-11-01}}).</ref>

Three different printings of Pius V's Roman Missal, with minor variations, appeared in 1570, a folio and a quarto edition in Rome and a folio edition in Venice. A reproduction of what is considered to be the earliest, referred to therefore as the ''editio princeps'', was produced in 1998.<ref>{{ISBN|88-209-2547-8}}; publisher: Libreria Editrice Vaticana; introduction and appendix by Manlio Sodi and Achille Maria Triacca</ref> In the course of the printing of the ''editio princeps'', some corrections were made by pasting revised texts over parts of the already printed pages.<ref>Introduction to the reproduction of the ''editio princeps'', pages XXVI-XXX</ref> There were several printings again in the following year 1571, with various corrections of the text.<ref>Introduction to the reproduction of the ''editio princeps'', pages XXI</ref>

==Historical variations==
[[File:Missale Romanum Glagolitice.jpg|thumbnail|[[Missale Romanum Glagolitice|Missale Romanum]] in [[Croatian language|Croatian]] [[Glagolitic script]] printed in 1483]]
In the [[apostolic constitution]] ([[papal bull]]) ''[[Quo primum]]'', with which he prescribed use of his 1570 edition of the Roman Missal, Pius V decreed: "We order and enjoin that nothing must be added to Our recently published Missal, nothing omitted from it, nor anything whatsoever be changed within it." This of course did not exclude changes by a Pope, and Pope Pius V himself added to the Missal the feast of [[Our Lady of Victory]], to celebrate the victory of [[Battle of Lepanto (1571)|Lepanto]] of 7 October 1571. His immediate successor, [[Pope Gregory XIII]], changed the name of this feast to "The Most Holy Rosary of the Blessed Virgin Mary" and [[Pope John XXIII]] changed it to "Our Lady of the Rosary".

Pius V's work in severely reducing the number of feasts in the Roman calendar (see [[Tridentine calendar#Comparison with other Roman calendars|this comparison]]) was very soon further undone by his successors. Feasts that he had abolished, such as those of the Presentation of Mary, Saint Anne and Saint Anthony of Padua, were restored even before Clement VIII's 1604 typical edition of the Missal was issued.

In the course of the following centuries new feasts were repeatedly added and the [[General Roman Calendar of 1954#Rank of feast days|ranks]] of certain feasts were raised or lowered. A comparison between Pope Pius V's [[Tridentine calendar]] and the [[General Roman Calendar of 1954]] shows the changes made from 1570 to 1954. Pope Pius XII made a general revision in [[General Roman Calendar of Pope Pius XII|1955]], and Pope John XXIII made further general revisions in [[General Roman Calendar of 1960|1960]] simplifying the terminology concerning the ranking of liturgical celebrations.

While keeping on 8 December what he called the feast of "the Conception of Blessed Mary" (omitting the word "Immaculate"), Pius V suppressed the existing special Mass for the feast, directing that the Mass for the Nativity of Mary (with the word "Nativity" replaced by "Conception") be used instead. Part of that earlier Mass was revived in the Mass that [[Pope Pius IX]] ordered to be used on the feast.

===Typical editions of the Roman Missal===
In addition to such occasional changes, the Roman Missal was subjected to general revisions whenever a new "[[typical edition]]" (an official edition whose text was to be reproduced in printings by all publishers) was issued.

After Pius V's original Tridentine Roman Missal, the first new typical edition was promulgated in 1604 by [[Pope Clement VIII]], who in 1592 had issued a revised edition of the [[Vulgate]]. The Bible texts in the Missal of Pope Pius V did not correspond exactly to the new Vulgate, and so Clement edited and revised Pope Pius V's Missal, making alterations both in the scriptural texts and in other matters. He abolished some prayers that the 1570 Missal obliged the priest to say on entering the church; shortened the two prayers to be said after the [[Confiteor]]; directed that the words "{{lang|la|Haec quotiescumque feceritis, in meam memoriam facietis}}" ("Do this in memory of me") should not be said while displaying the chalice to the people after the consecration, but before doing so; inserted directions at several points of the Canon that the priest was to pronounce the words inaudibly; suppressed the rule that, at High Mass, the priest, even if not a bishop, was to give the final blessing with three signs of the cross; and rewrote the rubrics, introducing, for instance, the ringing of a small bell.{{efn|name=similarlyclementviii}}<ref>[http://perso.orange.fr/civitas.dei/PapalMass.htm Solemn Papal Mass].

The next typical edition was issued in 1634, when [[Pope Urban VIII]] made another general revision of the Roman Missal.<ref>{{Cite web |url=http://www.catholicliturgy.com/index.cfm/FuseAction/DocumentContents/Index/2/SubIndex/41/DocumentIndex/403 |title=Apostolic Constitution ''Si quid est'' |access-date=2004-08-14 |archive-date=2013-09-27 |archive-url=https://web.archive.org/web/20130927164401/http://www.catholicliturgy.com/index.cfm/FuseAction/DocumentContents/Index/2/SubIndex/41/DocumentIndex/403 |url-status=dead }}</ref>

There was no further typical edition until that of [[Pope Leo XIII]] in 1884.<ref>[http://www.newadvent.org/cathen/10354c.htm ''Missal''] in Catholic Encyclopedia</ref> It introduced only minor changes, not profound enough to merit having the papal bull of its promulgation included in the Missal, as the bulls of 1604 and 1634 were.

In 1911, with the bull ''Divino Afflatu'', [[Pope Pius X]] made significant changes in the rubrics.<ref>{{Cite news|url=https://www.papalencyclicals.net/pius10/p10divino.htm|title=Divino Afflatu|newspaper=Papal Encyclicals|date=November 1, 1911}}</ref>

[[Pope Pius XII]] radically revised the [[Palm Sunday]] and [[Easter Triduum]] liturgy, suppressed many [[vigil]]s and octaves and made other alterations in the calendar (see [[General Roman Calendar of Pope Pius XII]]). John XXIII's 1960 [[Code of Rubrics]] were incorporated in the final 1962 typical edition of the Tridentine Missal, replacing both Pius X's "Additions and Changes in the Rubrics of the Missal" and the earlier "General Rubrics of the Missal".

The [[General Roman Calendar]] was revised partially in [[General Roman Calendar of Pope Pius XII|1955]] and [[General Roman Calendar of 1960|1960]] and completely in 1969 in [[Pope Paul VI]]'s ''[[motu proprio]]'' ''[[Mysterii Paschalis]]'', again reducing the number of feasts.<ref>[https://www.vatican.va/holy_father/paul_vi/motu_proprio/documents/hf_p-vi_motu-proprio_19690214_mysterii-paschalis_en.html ''Mysterii Paschalis''] and [http://ordorecitandi.com/nav/CalendarComparisonMay2002.doc Ordorecitandi website] {{Webarchive|url=https://web.archive.org/web/20040407130758/http://www.ordorecitandi.com/nav/CalendarComparisonMay2002.doc |date=2004-04-07 }}</ref>

===1962 Missal===
[[File:Elevation_of_Chalice_1.jpg|upright=1.2|right|thumb|Elevation of the Chalice during consecration at a [[Missa Cantata]]]]
The Roman Missal issued by Pope John XXIII in 1962 differed from earlier editions in a number of ways.
* It incorporated the change made by John XXIII in 1962, when he inserted into the [[canon of the Mass]] the name of [[Saint Joseph]], the first change for centuries in the canon of the Mass.<ref>{{cite web |url=http://www.catholicdigest.com/articles/faith/saints/2013/06-24/st-joseph--the-mass |title=Richard Breyer, "St. Joseph & the Mass" in ''Catholic Digest'' |access-date=2014-06-28 |archive-url=https://web.archive.org/web/20150226061339/http://www.catholicdigest.com/articles/faith/saints/2013/06-24/st-joseph--the-mass |archive-date=2015-02-26 |url-status=dead }}</ref>
*In addition, the 1962 Missal removed the adjective ''perfidis'' from the [[Good Friday Prayer for the Jews]].<ref>[[Walter Homolka]], [[Erich Zenger]] (Ed.): ''„damit sie Jesus Christus erkennen“. Die neue Karfreitagsfürbitte für die Juden'', p. 17.</ref>

In 2007, Pope Benedict XVI authorized, under certain conditions, continued use of this 1962 edition of the Roman Missal as an "extraordinary form",<ref name="auto"/> alongside the later form, introduced in 1970, which he called the normal or ordinary form.<ref>"The Missal published by Paul VI and then republished in two subsequent editions by John Paul II, obviously is and continues to be the normal Form – the ''Forma ordinaria'' – of the Eucharistic Liturgy" ([https://www.vatican.va/holy_father/benedict_xvi/letters/2007/documents/hf_ben-xvi_let_20070707_lettera-vescovi_en.html Pope Benedict XVI's letter to the bishops on the occasion of the publication of ''Summorum Pontificum'').]</ref>

* This included a new replacement [[Good_Friday_prayer_for_the_Jews#Changes_by_Benedict_XVI|Good Friday Prayer for the Jews]] for the 1962 liturgy.

Pre-1962 forms of the Roman Rite, which some individuals and groups employ,<ref>Their dislike of the 1962 Missal is expressed for instance in a [http://www.traditionalmass.org/articles/article.php?id=18&catname=6 list of differences] prepared by [[Daniel Dolan]].</ref> are generally not authorized for liturgical use, but in early 2018 the [[Ecclesia Dei Commission]] granted communities served by the [[Priestly Fraternity of Saint Peter]] an indult to use, at the discretion of the Fraternity's superior, the pre-1955 Holy Week liturgy for three years (2018, 2019, 2020).<ref>{{Cite web|url=http://www.windsorlatinmass.org/wtnews/180311.pdf|title=Tridentine Community News, 11 March 2018}}</ref>

== Liturgical structure ==
The Mass is divided into two parts, the [[Mass of the Catechumens]] and the [[Mass of the Faithful]]. Catechumens, those being instructed in the faith,<ref>{{cite web |title = The Collaborative International Dictionary of English v.0.48 |year = 1913 |url = http://www.dict.org/bin/Dict?Form=Dict2&Database=*&Query=catechumen |access-date = 2008-03-25 }}</ref> were once dismissed after the first half, not having yet professed the faith. Profession of faith was considered essential for participation in the [[Eucharist]]ic sacrifice.<ref>{{cite web |last = Chapman |first = John |title = Didache |year = 1908 |url = http://www.newadvent.org/cathen/04779a.htm |access-date = 2008-03-25 |quote=Let no one eat or drink of the Eucharist with you except those who have been baptized in the name of the Lord. }}</ref>

This rule of the ''[[Didache]]'' is still in effect. It is only one of the three conditions (baptism, right faith and right living) for admission to receiving [[Eucharist|Holy Communion]] that the Catholic Church has always applied and that were already mentioned in the early 2nd century by Saint [[Justin Martyr]]: "And this food is called among us the [[Eucharist in the Catholic Church|Eucharist]], of which no one is allowed to partake but the man who believes that the things which we teach are true, and who has been washed with the washing that is for the remission of sins, and unto regeneration, and who is so living as Christ has enjoined" (''[[First Apology]]'', Chapter LXVI).

===Before Mass===
[[Asperges]] (Sprinkling with [[holy water]], [[Psalms|Psalm]] [http://drbo.org/cgi-bin/d?b=drb&bk=21&ch=050&l=3%2C+9 51:9, 3]) is an optional [[penance|penitential]] rite that ordinarily precedes only the principal [[Mass (Catholic Church)|Mass]] on Sunday.{{efn|name=itis}} In the sacristy, a priest wearing an [[alb]], if he is to celebrate the Mass, or [[surplice]], if he is not the celebrant of the Mass, and vested with a [[Stole (vestment)|stole]], which is the color of the day if the priest is the celebrant of the Mass or purple if he is not the celebrant of the Mass, exorcises and blesses salt and water, then puts the blessed salt into the water by thrice sprinkling it in the form of a cross while saying once, "Commixtio salis et aquæ pariter fiat in nomine Patris, et Filii et Spiritus Sancti" (May a mixture of salt and water now be made in the name of the Father, and of the Son, and of the Holy Spirit). After that, the priest, vested in a [[cope]] of the color of the day, while the choir sings an antiphon and a verse of [[Psalms|Psalm]] 50/51 or 117/118, sprinkles with the holy water the altar three times, and then the clergy and the congregation. This rite, if used, precedes the Prayers at the Foot of the Altar. During the [[Easter]] season, the "Asperges me..." verse is replaced by the "Vidi aquam..." verse, and "Alleluia" is added to the "Ostende nobis..." verse and to its response.

Following the Asperges, Mass begins.

===Mass of the Catechumens===
The first part is the Mass of the Catechumens.<ref>{{Cite web |url=http://www.catholicliturgy.com/index.cfm/FuseAction/Text/Index/4/SubIndex/66/ContentIndex/18/Start/17 |title=Text of Mass of the Catechumens |access-date=2004-05-16 |archive-date=2014-02-26 |archive-url=https://web.archive.org/web/20140226115813/http://www.catholicliturgy.com/index.cfm/FuseAction/Text/Index/4/SubIndex/66/ContentIndex/18/Start/17 |url-status=dead }}</ref>

====Prayers at the foot of the altar====
<!-- This section title serves to provide a permanent target for incoming section links including the redirect page [[Prayers at the Foot of the Altar]]. Please do not modify it. -->
[[File:Tridentská Mše v Prostějově 2023.jpg|thumb|right|upright=1.2|Prayers at the foot of the altar at a Missa Cantata]]
[[File:Missa tridentina 001.jpg|right|thumb|Prayers at the foot of the altar at a Low Mass]]
The sequence of Prayers at the foot of the altar is:
* [[Sign of the cross]]
:The priest, after processing in—at solemn Mass with [[deacon]], and subdeacon, master of ceremonies and servers, and at other Masses with one or more servers—and at Low Mass placing the veiled chalice on the centre of the altar, makes the sign of the cross at the foot of the altar. At Solemn Mass, the chalice is placed beforehand on the [[credence table]].
* Psalm [https://drbo.org/chapter/21042.htm 42] ({{bibleref2|Psalm|43|NRSVCE}} MT, i.e. Masoretic numbering), known by its incipit ''{{lang|la|Iudica me}}'', is recited, except in Masses of the season during [[Passiontide]] and in [[Requiem|Requiem Masses]]. It is preceded and followed by an [[antiphon]] of the same psalm: "''{{lang|la|Introibo ad altare Dei, ad Deum qui lætificat iuventutem meam}}''" (Translation: "I shall go in to the altar of God: to God who giveth joy to my youth"),<ref>{{Cite web|url=http://www.drbo.org/chapter/21042.htm|title=Douay-Rheims Bible, Psalms Chapter 42|website=www.drbo.org}}</ref> is recited by the priest, alternating with the deacon and subdeacon (if present) or servers. 
*{{bibleref2|Psalm|123:8|DRA}} is recited:
:{{dialogue|Priest|Our help is in the name of the Lord,|mood1=makes the sign of the cross|Servers|Who made heaven and earth.}}
*The double form of a prayer of general confession of sins, known by its incipit ''[[Confiteor]]'' (I confess), is recited:
:{{dialogue|Priest|''{{lang|la|Confíteor Deo omnipoténti, beátæ Maríæ semper Vírgini, beáto Michaéli Archángelo, beáto Ioanni Baptístæ, sanctis Apóstolis Petro et Paulo, ómnibus Sanctis, et vobis, fratres (tibi, Pater), quia peccávi nimis cogitatióne, verbo et ópere:}} (while striking the breast three times) {{lang|la|mea culpa, mea culpa, mea máxima culpa. Ídeo precor beátam Maríam semper Vírginem, beátum Michaélem Archángelum, beátum Ioánnem Baptístam, sanctos Apóstolos Petrum et Paulum, omnes Sanctos, et vos, fratres (te, Pater), oráre pro me ad Dóminum Deum nostrum.}}''|mood1=while bowing low}}
::(Translation: I confess to almighty [[God in Christianity|God]], to [[Blessed Virgin Mary|blessed Mary ever Virgin]], to [[Michael (archangel)|blessed Michael the archangel]], to [[John the Baptist|blessed John the Baptist]], to the [[holy]] [[Twelve Apostles|apostles]] [[Saint Peter|Peter]] and [[Paul of Tarsus|Paul]], to all the [[saint]]s, and to you, brethren, that I have [[sin]]ned exceedingly in thought, word, and deed through my fault, through my fault, through my most grievous fault. Therefore, I beseech blessed Mary ever Virgin, blessed Michael the archangel, blessed John the Baptist, the holy apostles Peter and Paul, all the saints and you, brethren, to [[Catholic prayer|pray]] for me to the Lord our God.) 
:The servers pray for the priest: "May Almighty God have mercy on thee, forgive thee thy sins, and bring thee to life everlasting." Then it is the ministers' or servers' turn to confess sinfulness and to ask for prayers. They use the same words as those used by the priest, except that they say "you, Father", in place of "you, brethren", and the priest responds with the same prayer that the servers have used for him (but using the plural number) plus an extra prayer.
* The following verses are then said by priest and ministers (or servers):

<poem style="float:left;">::℣. Deus, tu conversus vivificábis nos.
::℟. Et plebs tua lætábitur in te.
::℣. Óstende nobis, Dómine, misericórdiam tuam.
::℟. Et salutáre tuum da nobis.
::℣. Dómine, exáudi orátionem meam.
::℟. Et clamor meus ad te véniat.
::℣. Dóminus vobíscum.
::℟. Et cum spíritu tuo.</poem>
<poem style="margin-left:2em; float:left;">Thou wilt turn, O God, and bring us to life: (Ps. 84:7–8)<ref>{{Cite web|url=http://www.drbo.org/chapter/21084.htm|title=Douay-Rheims Bible, Psalms Chapter 84|website=www.drbo.org}}</ref>
And thy people shall rejoice in thee.
Shew us, O Lord, thy mercy.
And grant us thy salvation.
O Lord, hear my prayer.
And let my cry come unto thee.
The Lord be with you.
And with thy spirit.</poem>{{Clear|left}}

The priest then says, ''{{lang|la|Oremus}}'' (Let us pray). After this he ascends to the altar, praying silently "Aufer a nobis, quæsumus, Dómine, iniquitates nostras: ut ad Sancta sanctorum puris mereámur méntibus introíre. Per Christum Dóminum nostrum. Amen." (Translation: Take away from us our iniquities, we beseech thee O Lord, that with pure minds we may worthily enter into the holy of holies"), a reference to [[Book of Exodus|Exodus]] [http://drbo.org/cgi-bin/d?b=drb&bk=02&ch=026&l=33-34 26:33–34], [[Books of Kings|1 Kings]] [http://drbo.org/cgi-bin/d?b=drb&bk=11&ch=006&l=16 6:16], [[Books of Kings|1 Kings]] [http://drbo.org/cgi-bin/d?b=drb&bk=11&ch=008&l=6 8:6], [[Books of Chronicles|2 Chronicles]] [http://drbo.org/cgi-bin/d?b=drb&bk=14&ch=003&l=8 3:8], [[Book of Ezekiel|Ezekiel]] [http://drbo.org/cgi-bin/d?b=drb&bk=31&ch=041&l=4 41:4], and others. He places his joined hands on the edge of the altar, so that only the tips of the small fingers touch the front of it, and silently prays that, by the merits of the Saints whose relics are in the altar, and of all the Saints, God may pardon all his sins. At the words ''{{lang|la|quorum relíquiæ hic sunt}}'' (whose relics are here), he spreads his hands and kisses the altar.

====Priest at the altar====
[[File:Dominus vobiscum 1960s.jpg|thumb|''Dominus vobiscum'' ("The Lord be with you") before the [[Collect]].<br /><small>In the Tridentine Mass the priest should keep his eyes downcast at this point.<ref>{{Cite web |url=http://www.sanctamissa.org/en/rubrics/ |title=Rubrics V |access-date=2009-03-23 |archive-date=2008-04-12 |archive-url=https://web.archive.org/web/20080412042637/http://www.sanctamissa.org/en/rubrics/ |url-status=dead }}</ref></small>]]
* [[Introit]]
** The priest again makes the sign of the Cross while he begins to read the Introit, which is usually taken from a [[Psalm]]. Exceptions occur: e.g. the Introit for [[Easter]] Sunday is adapted from [[Book of Wisdom|Wis]] [http://drbo.org/cgi-bin/d?b=drb&bk=25&ch=010&l=20-21 10:20–21], and the antiphon in Masses of the Blessed Virgin Mary was from the poet [[Coelius Sedulius|Sedulius]]. This evolved from the practice of singing a full Psalm, interspersed with the antiphon, during the entrance of the clergy, before the Prayers at the Foot of the Altar were added to the Mass in medieval times. This is indicated by the very name of "Introit".
* [[Kyrie]]
** This part of Mass is a linguistic marker of the origins of the Roman liturgy in [[Greek language|Greek]]. "Kyrie, eleison; Christe, eleison; Kyrie, eleison." means "Lord, have mercy; Christ have mercy;..." Each phrase is said (or sung) three times.
* [[Gloria in excelsis Deo]]
** The first line of the ''Gloria''<ref>{{Cite web |url=http://home.earthlink.net/~thesaurus/thesaurus/Trinitas/Gloria.html |title=Text in Latin and English |access-date=2004-05-16 |archive-date=2012-03-14 |archive-url=https://web.archive.org/web/20120314114752/http://home.earthlink.net/~thesaurus/thesaurus/Trinitas/Gloria.html |url-status=dead }}</ref> is taken from [[Gospel of Luke|Lk]] {{bibleverse-nb||Luke|2:14}}. The ''Gloria'' is omitted during the penitential liturgical seasons of [[Advent]], [[Septuagesima]], [[Lent]], and Passiontide, in which violet vestments are worn, but is used on feasts falling during such seasons, as well as on Holy (Maundy) Thursday. It is always omitted for a Requiem Mass.
* The [[Collect]]
** The priest turns toward the people and says, "Dominus vobiscum." The servers respond: "Et cum spiritu tuo." ("The Lord be with you." "And with thy spirit"). The [[Collect]] follows, a prayer not drawn directly from Scripture. It tends to reflect the season.

====Instruction====
* The priest reads the [[Epistles|Epistle]], primarily an extract from the [[letters of St. Paul]] to various churches. In his ''motu proprio'' ''[[Summorum Pontificum]]'', Pope Benedict XVI permitted this to be read in the vernacular language when Mass is celebrated with the people.<ref>{{Cite web |url=http://www.sanctamissa.org/EN/resources/summorum-pontificum.html |title=''Summorum Pontificum'', article 6 |access-date=2007-09-21 |archive-date=2012-10-10 |archive-url=https://web.archive.org/web/20121010043928/http://www.sanctamissa.org/en/resources/summorum-pontificum.html |url-status=dead }}</ref>
* Between the Epistle and the Gospel, two (rarely three) choir responses are sung or said. Usually these are a [[Gradual]] followed by an [[Alleluia]]; but between [[Septuagesima]] Sunday and [[Holy Saturday]], or in a [[Requiem Mass]] or other penitential Mass the Alleluia is replaced by a [[Tract (liturgy)|Tract]], and between [[Easter]] Sunday and [[Pentecost]] the Gradual is replaced by a second Alleluia. On a few exceptional occasions (most notably Easter, [[Pentecost]], Corpus Christi, and in a Requiem Mass), a [[Sequence (poetry)|Sequence]] follows the Alleluia or Tract.
** The Gradual is partly composed of a portion of a [[Psalm]].
* [[File:NEC Traditional Latin Mass 19 July 2024 Gospel.jpg|thumb|The Deacon preparing to chant the Gospel]]The [[Gospel]] reading, an extract from one of the four Gospels
** Before the reading or chanting of the Gospel, the priest prays: "Cleanse my heart and my lips, O almighty God, who didst cleanse the lips of the prophet [[Isaiah|Isaias]]...", a reference to [[Book of Isaiah|Isaiah]] [http://drbo.org/cgi-bin/d?b=drb&bk=27&ch=006&l=6-7 6:6]. In this passage, after being cleansed by the [[Angels in Christianity|angel]], Isaiah was instructed to prophesy.
* The [[Homily]]
** The rite of Mass as revised by Pope Pius V (the Tridentine Mass) does not consider a sermon obligatory and speaks of it instead as merely optional: it presumes that the [[Creed]], if it is to be said, will follow the Gospel immediately, but adds: "If, however, someone is to preach, the Homilist, after the Gospel has been finished, preaches, and when the sermon or moral address has been completed, the [[Credo]] is said, or if it is not to be said, the Offertory is sung."<ref>{{Cite web |url=http://www.sanctamissa.org/en/rubrics/ |title=The Rubrics of the Missale Romanum 1962: VI.

* The [[Credo|Creed]]
** The [[Niceno-Constantinopolitan Creed]], professing faith in [[God the Father]], in [[God the Son]], in [[God the Holy Spirit]], and in the [[Four Marks of the Church|one, holy, catholic and apostolic Church]]. At the mention of the [[Incarnation (Christianity)|Incarnation]], the celebrant and the congregation genuflect.

===Mass of the Faithful===
The second part is the Mass of the Faithful.<ref>{{Cite web |url=http://www.catholicliturgy.com/index.cfm/FuseAction/Text/Index/4/SubIndex/66/ContentIndex/19/Start/17 |title=Text of Mass of the Faithful |access-date=2004-05-16 |archive-date=2014-02-26 |archive-url=https://web.archive.org/web/20140226121459/http://www.catholicliturgy.com/index.cfm/FuseAction/Text/Index/4/SubIndex/66/ContentIndex/19/Start/17 |url-status=dead }}</ref>

====Offertory====
[[File:Chanoine Dominique Aubert en 2009.jpg|upright=1.2|thumb|Elevation of the [[Chalice (cup)|chalice]] during the [[Canon of the Mass]] at a [[Missa Cantata]] ]]
* [[Offertory]] Verse
** After greeting the people once more ("''Dominus vobiscum/Et cum spiritu tuo''") and giving the invitation to pray (''Oremus''), the priest enters upon the Mass of the Faithful, from which the non-baptized were once excluded. He reads the Offertory Verse, a short quotation from Holy Scripture which varies with the Mass of each day, with hands joined.
* Offertory Prayers
** The priest offers the host, holding it on the paten at breast level and praying that, although he is unworthy, God may accept "this spotless host (or victim, the basic meaning of ''hostia'' in Latin) for his own innumerable sins, offences and neglects, for all those present, and for all faithful Christians living and dead, that it may avail unto salvation of himself and those mentioned. He then mixes a few drops of water with the wine, which will later become the Blood of Jesus, and holding the chalice so that the lip of the chalice is about the height of his lips, offers "the chalice of salvation", asking that it may "ascend with a sweet fragrance." He then prays a prayer of contrition adapted from [[Book of Daniel|Dan]] [http://drbo.org/cgi-bin/d?b=drb&bk=32&ch=003&l=39-40 3:39–40].
* Incensing of the offerings and of the faithful
** At a [[Solemn Mass|High Mass]], the priest blesses the [[incense]], then incenses the bread and wine. Among the prayers the priest says is [[Psalms|Psalm]] [http://drbo.org/cgi-bin/d?b=drb&bk=21&ch=140&l=2-4 141:2–4]: "Let my prayer, O Lord, be directed as incense in Thy sight;...", which is prayed as he incenses the altar. The priest then gives the thurible to the deacon, who incenses the priest, then the other ministers and the congregation.
* Washing the hands
** The priest prays [[Psalms|Psalm]] [http://drbo.org/cgi-bin/d?b=drb&bk=21&ch=025&l=6-12 26:6–12]: "I will wash my hands among the innocent..."
* Prayer to the [[Trinity|Most Holy Trinity]]
** This prayer asks that the [[Trinity|Divine Trinity]] may receive the oblation being made in remembrance of the passion, resurrection and ascension of Jesus and in honour of blessed Mary ever Virgin and the other saints, "that it may avail to their honour and our salvation: and that they may vouchsafe to intercede for us in [[Heaven in Christianity|heaven]]..."
* [[Orate fratres]], [[Suscipiat]] and [[Secret (liturgy)|Secret]]; [[Amen]] concludes Offertory
** Here the priest turns to the congregation and says the first two words, "Orate, fratres", in an elevated tone and then turns around while finishing the exhortation in the secret tone. "Pray, Brethren, that my sacrifice and yours may be acceptable to [[God the Father]] almighty."
** The altar servers respond with the [[Suscipiat]] to which the priest secretly responds, "Amen.": ''Suscipiat Dominus sacrificium de manibus tuis, ad laudem et gloriam nominis sui, ad utilitatem quoque nostram, totiusque ecclesiæ suae sanctæ.'' A translation in the English is: "May the Lord accept this sacrifice at your hands, to the praise and glory of His name, for our good and the good of all His Holy Church."
** The Priest then says the day's Secret inaudibly, and concludes it with ''Per omnia sæcula sæculorum'' aloud.
** The altar servers and (in dialogue Mass) the congregation respond: "Amen."

====Consecration====
[[File:Generalvikar Dr. Weis 1.JPG|right|thumb|Part of the [[Canon of the Mass]] at a [[Low Mass]]]]
* [[Preface (Liturgy)|Preface]] of the Canon
**"The [[Canon of the Mass|Roman Canon]] dates in essentials from before [[Pope Gregory I|St. Gregory the Great]], who died in 604, and who is credited with adding a phrase to it.<ref>{{CathEncy|wstitle=Pope St. Gregory I ("the Great")}}</ref> (See [[History of the Roman Canon]].) It contains the main elements found in almost all rites, but in an unusual arrangement and it is unclear which part should be considered to be the [[Epiclesis]].
** Dominus vobiscum. ''Et cum spiritu tuo.'' [[Sursum corda]]. ''Habemus ad Dominum.'' Gratias agimus Domino Deo nostro. ''Dignum et iustum est.'' The first part can be seen above at the Collect; the rest means: "Lift up your hearts. We lift them up to the Lord. Let us give thanks to the Lord our God. It is right and just".
**Next a preface is prayed, indicating specific reasons for giving thanks to God. This leads to the [[Sanctus]].<ref>{{Cite web |url=http://home.earthlink.net/~thesaurus/thesaurus/Trinitas/Sanctus.html |title=Santus |access-date=2004-05-16 |archive-date=2012-03-14 |archive-url=https://web.archive.org/web/20120314112918/http://home.earthlink.net/~thesaurus/thesaurus/Trinitas/Sanctus.html |url-status=dead }}</ref>

*** Here the priest prays for the living, that God may guard, unite and govern the Church together with the Pope and "all those who, holding to the truth, hand on the catholic and apostolic faith". Then specific living people are mentioned, and the congregation in the church. Next, Mary ever Virgin, Saint Joseph, the Apostles, and some Popes and other Martyrs are mentioned by name, as well as a generic "and all your Saints", in communion with whom prayer is offered.
** Prayers preparatory to the consecration

*** The passage [[Gospel of Luke|Lk]] [http://drbo.org/cgi-bin/d?b=drb&bk=49&ch=022&l=19-20 22:19–20] is key in this section.

On this phrase, see ''[[Memorial Acclamation#Mysterium fidei|Mysterium fidei]]''.
** Oblation of the victim to God
***An oblation is an offering;<ref>{{Cite web |title=Oblation |url=http://dict.org/bin/Dict?Form=Dict2&Database=*&Query=oblation |website=dict.org}}</ref> the pure, holy, spotless victim is now offered, with a prayer that God may accept the offering and command his holy angel to carry the offering to God's altar on high, so that those who receive the Body and Blood of Christ "may be filled with every grace and heavenly blessing".
** Remembrance of the Dead
*** The priest now prays for the dead ("those who have gone before us with the sign of faith and rest in the sleep of peace") and asks that they be granted a place of refreshment, light and peace. This is followed by a prayer that we be granted fellowship with the Saints. John the Baptist and fourteen martyrs, seven men and seven women, are mentioned by name.
** End of the Canon and doxology with minor elevation
*** The concluding [[doxology]] is: ''Per ipsum, et cum ipso, et in ipso, est tibi Deo Patri omnipotenti, in unitate Spiritus Sancti'', ("Through him, and with him, and in him, O God, there is to you, almighty Father, in the unity of the Holy Spirit", − spoken silently while making five signs of the cross with the host) ''omnis honor, et gloria.'' ("all glory and honour." − still silently while briefly raising host and chalice a little together). This is followed by replacing the host on the corporal and the pall on the chalice and genuflecting. After this the priest sings or says aloud: ''Per omnia sæcula sæculorum'' ("For ever and ever.") The response "Amen" symbolically ratifies the Canon prayer.

====Elevation candle====
[[Image:Messe mit Wandlungskerze Beuron.jpg|thumb|left|[[Beuron Art School]] representation of an elevation candle, mistakenly placed at the Gospel side and upon the altar]]
Until 1960, the Tridentine form of the Roman Missal laid down that a candle should be placed at the Epistle side of the altar and that it should be lit at the showing of the consecrated sacrament to the people.<ref>"Ab eadem parte Epistolae paretur cereus ad elevationem Sacramenti accendendus" (Rubricae generales Missalis, XX)</ref> In practice, except in monasteries and on special occasions, this had fallen out of use long before Pope John XXIII replaced the section on the general rubrics of the Roman Missal with his [[Code of Rubrics]], which no longer mentioned this custom. On this, see [[Elevation (liturgy)#Elevation candle|Elevation candle]].

====Communion====
[[File:Offertory Offertorium Suscipe Sancte Pater.jpg|thumb|Before receiving Communion from the chalice, the priest makes the sign of the cross over himself, saying (in Latin): May the Blood of our Lord Jesus Christ preserve my soul unto everlasting life. Amen.]]

::::::::::::*The "[[Embolism (liturgy)|Libera nos]]" is an extension of the Lord's Prayer developing the line "sed libera nos a malo" ("but deliver us from evil"). The priest prays that we may be delivered from all evils and that the Virgin Mary, Mother of God, together with the apostles and saints, may intercede to obtain for us peace in our day.
:::::::::::*[[Fraction (religion)|Fraction]] of the Host
::::::::::::*During the preceding prayer, the priest breaks the consecrated Host into three parts, and after concluding the prayer drops the smallest part into the Chalice while praying that this commingling and consecration of the Body and Blood of Christ may "be to us who receive it effectual to life everlasting."
:::::::::::* [[Agnus Dei (liturgy)|Agnus Dei]]
::::::::::::* "Agnus Dei" means "[[Lamb of God]]". The priest then prays: "Lamb of God, who takest away the sins of the world, have mercy on us." He repeats this, and then adds: "Lamb of God, who takest away the sins of the world, grant us peace." The Mass of the Last Supper on Holy Thursday has "have mercy on us" all three times. In Requiem Masses, the petitions are "grant them rest" (twice), followed by "grant them eternal rest."
* The [[Holy kiss|Pax]]
**The priest asks Christ to look not at the priest's sins but at the faith of Christ's Church, and prays for peace and unity within the Church. Then, if a High Mass is being celebrated, he gives the sign of peace to the deacon, saying: "Peace be with you."
*Prayers preparatory to the Communion
** In the first of these two prayers for himself, the priests asks that by Holy Communion he may be freed from all his iniquities and evils, be made to adhere to the commandments of Jesus and never be separated from him. In the second he asks: "Let not the partaking of Thy Body, O Lord Jesus Christ...turn to my judgment and condemnation: but through Thy goodness may it be unto me a safeguard...."
* Receiving of the Body and Blood of our Lord
** The priest quietly says several prayers here, before receiving Communion. The first is said in a low voice while taking up the Host onto the paten. The second of them, spoken three times in a slightly audible voice,<ref>In pre-1962 editions of the Roman Missal, only the first four words, "Domine, non sum dignus", were to be said in the slightly audible voice.</ref> while the priest holds the Host in his left hand and strikes his breast with his right, is based on {{Bibleverse||Matthew|8:8}}: "Lord, I am not worthy...." Then, after having reverently consumed the Host, he takes up the chalice while in a low voice reciting {{Bibleverse||Psalm|116:12–13}}: "What shall I render to the Lord, for all the things he hath rendered unto me? I will take the chalice of salvation; and I will call upon the name of the Lord." immediately adding {{Bibleverse||Psalm|18:3}}: "Praising I will call upon the Lord: and I shall be saved from my enemies."

**If the priest is to give Communion to others, he holds up a small host and says aloud: "Behold the Lamb of God ...", and three times: "Lord, I am not worthy ...". He then gives Communion, first making with the host the sign of the cross over each communicant, while saying: "May the Body of Our Lord Jesus Christ preserve your soul for eternal life. Amen."<ref>''Ritus servandus'', X, 6 of the 1962 Missal</ref>

==== Conclusion ====
[[File:IteMissaEst.jpg|thumb|upright=1.45|"Ite, missa est" sung by the [[deacon]] at a [[Solemn Mass]]]]
* Prayers during the [[Ablution in Christianity|Ablutions]]
** The prayers now focus on what has been received, that "we may receive with a pure mind", "that no stain of sin may remain in me, whom these pure and holy sacraments have refreshed."
* [[Communion Antiphon]] and [[Postcommunion]]
** The communion antiphon is normally a portion of a Psalm. The Postcommunion Prayer is akin to the Collect in being an appropriate prayer not directly drawn from Scripture.
* [[Ite Missa est]]; Blessing
** "Go, it is the dismissal." The word "Mass" derives from this phrase.
** After saying a silent prayer for himself, the priest then gives the people his blessing.
** Prior to the revisions of Pope Pius XII and Pope John XXIII, the ''Ite Missa est'' was replaced with ''[[Benedicamus Domino]]'' ("Let us bless the Lord") on days in which the ''Gloria'' was not said and the rubrics required the priest to wear violet vestments (i.e., Masses of the season during Advent, Septuagesima, Lent and Passiontide; vigils; certain votive Masses). In the 1962 Missal, ''[[Benedicamus Domino]]'' is said only when the Mass is followed by another liturgical action, such as the [[Procession|Eucharistic Processions]] on [[Maundy Thursday|Holy Thursday]] and Corpus Christi.
**  In Requiem Masses, the ''Ite Missa est'' is replaced with ''[[Rest in peace|Requiescat in pace]]'', with the response being "Amen" instead of ''[[Deo gratias]]''.
* The [[Last Gospel]]
** The priest then reads the Last Gospel, the beginning of the [[Gospel of John]], {{Bibleverse||John|1:1–14}}, which recounts the Incarnation of the Son of God. On certain occasions, as for instance at the Day Mass on Christmas Day, another Gospel passage was read instead because that Gospel is read as the Gospel of the Mass, but [[Pope John XXIII]]'s revision of the rubrics decreed that on those and on other occasions the Last Gospel should simply be omitted.
** In the pre-1955 Missal, the Gospel of a Sunday outranked by a feast is still said as a Proper Last Gospel instead of the beginning of St. John's Gospel.
* [[Hymns to Mary|Marian Antiphons]]
** Customarily a Marian Antiphon appointed to the season is sung at the end of Last Gospel and Leonine Prayers, except Maundy Thursday and Good Friday.

=== Prayers of the priest before and after Mass ===
The Tridentine Missal includes prayers for the priest to say before and after Mass.

In later editions of the Roman Missal, including that of 1962, the introductory heading of these prayers indicates that they are to be recited ''pro opportunitate'' (as circumstances allow),<ref>{{Cite web |url=http://www.latin-dictionary.org/Latin-English-Dictionary/Pro_opportunitate |title=Latin Dictionary |access-date=2014-12-02 |archive-url=https://web.archive.org/web/20150609074403/http://www.latin-dictionary.org/Latin-English-Dictionary/Pro_opportunitate |archive-date=2015-06-09 |url-status=dead }}</ref> which in practice means that they are merely optional and may be omitted. The original Tridentine Missal presents most of the prayers as obligatory, indicating as optional only a very long prayer attributed to [[Ambrose|Saint Ambrose]] (which later editions divide into seven sections, each to be recited on only one day of the week) and two other prayers attributed to Saint Ambrose and [[Thomas Aquinas|Saint Thomas Aquinas]] respectively.<ref>Manlio Sodi, Achille Maria Triacca (editors), ''Missale Romanum: Editio Princeps (1570)'' (Libreria Editrice Vaticana 1988 {{ISBN|978-88-209-2547-5}}), pp. 27–36.</ref>

In addition to these three prayers, the original Tridentine Missal proposes for the priest to recite before he celebrates Mass the whole of Psalms 83–85, 115, 129 (the numbering is that of the [[Septuagint]] and [[Vulgate]]), and a series of [[collect]]-style prayers. Later editions add, after the three that in the original Missal are only optional, prayers to the [[Mary, mother of Jesus|Blessed Virgin]], [[Saint Joseph]], all the angels and saints, and the saint whose Mass is to be celebrated, but, as has been said, treats as optional all the prayers before Mass, even those originally given as obligatory.<ref>{{Cite web|url=http://www.preces-latinae.org/thesaurus/AnteMissam.html|title=Orationes Ante Missam|website=www.preces-latinae.org}}</ref>

The original Tridentine Missal proposes for recitation by the priest after Mass three prayers, including the ''[[Adoro te devote]]''. Later editions place before these three the Canticle of the Three Youths ([[Book of Daniel|Dan]])<ref>{{Cite web|url=http://drbo.org/cgi-bin/d?b=drb&bk=32&ch=3|title=Douay-Rheims Bible, Daniel Chapter 3|website=drbo.org}}</ref> with three collects, and follow them with the ''[[Anima Christi]]'' and seven more prayers, treating as optional even the three prescribed in the original Tridentine Missal.<ref>{{Cite web|url=http://www.preces-latinae.org/thesaurus/PostMissam.html|title=Orationes Post Missam|website=www.preces-latinae.org}}</ref>

=== Leonine Prayers ===
From 1884 to 1965, the Holy See prescribed the recitation after [[Low Mass]] of certain prayers, originally for the solution of the [[Roman Question]] and, after this problem was solved by the [[Lateran Treaty]], "to permit tranquillity and freedom to profess the faith to be restored to the afflicted people of Russia".<ref>Allocution ''Indictam ante'' of 30 June 1930, in ''Acta Apostolicae Sedis'' 22 (1930), page 301</ref>

These prayers are known as the [[Leonine Prayers]] because it was [[Pope Leo XIII]] who on 6 January 1884 ordered their recitation throughout the world.

In 1964, with effect from 7 March 1965, the Holy See ended the obligation to recite the Leonine Prayers after Low Mass.<ref>{{Cite web |url=http://www.adoremus.org/Interoecumenici.html#anchor36482722 |title=Instruction ''Inter Oecumenici'', 48 j |access-date=2006-10-09 |archive-date=2007-06-14 |archive-url=https://web.archive.org/web/20070614002539/http://www.adoremus.org/Interoecumenici.html#anchor36482722 |url-status=dead }}</ref>

=== Participation of the faithful ===
[[File:Nuptial Mass Missa Nuptialis.jpg|thumb|[[Nuptial Mass]]]]
[[File:Communion during Missa Cantata.jpg|thumb|upright=1|Distribution of Communion at a Tridentine Mass: typically, the faithful kneel at the rail and receive on the tongue, with a [[paten]] held under their chin to protect against accidents. It is customary in most places for women to wear a [[Christian headcovering|veil]].]]

The participation of the congregation at the Tridentine Mass is interior, involving eye and heart, and exterior by mouth.<ref>[[Pope Pius X]] said: "If you wish to hear Mass as it should be heard, you must follow with eye, heart, and mouth all that happens at the altar. Further, you must pray with the Priest the holy words said by him in the Name of Christ and which Christ says by him" (The Daily Missal and Liturgical Manual from the Editio Typica of the Roman Missal and Breviary, 1962, Baronius Press, London, 2004, p. 897).</ref>

Except in the [[Dialogue Mass]] form, which arose about 1910 and led to a more active exterior participation of the congregation, the people present at the Tridentine Mass do not recite out loud the prayers of the Mass. Only the server or servers join with the priest in reciting the prayers at the foot of the altar (which include the [[Confiteor]]) and in speaking the other responses.{{efn|name=theygave}} Most of the prayers that the priest says are spoken inaudibly, including almost all the Mass of the Faithful: the offertory prayers, the [[Canon of the Mass]] (except for the preface and the final doxology), and (apart from the [[Agnus Dei (liturgy)|Agnus Dei]]) those between the [[Lord's Prayer]] and the [[postcommunion]].

At a [[Solemn Mass]] or [[Missa Cantata]], a choir sings the servers' responses, except for the Prayers at the Foot of the Altar. The choir sings the [[Introit]], the [[Kyrie]], the [[Gloria in Excelsis Deo|Gloria]], the [[Gradual]], the [[Tract (liturgy)|Tract]] or [[Alleluia]], the [[Credo]], the [[Offertory]] and [[Eucharist|Communion]] [[antiphon]]s, the [[Sanctus]], and the [[Agnus Dei (liturgy)|Agnus Dei]]. Of these, only the five that form part of the [[Ordinary of the Mass]] are usually sung at a Missa Cantata. In addition to the [[Gregorian Chant]] music for these, polyphonic compositions exist, some quite elaborate. The priest largely says quietly the words of the chants.

=== Comparison with other Western Christian liturgical rites ===
[[Jesuit]] priest [[:no:Rune P. Thuringer|Rune P. Thuringer]], writing in 1965, noted that "The eucharistic liturgy of the state [[Church of Sweden]], which is [[Lutheran]], is closer in many respects to the [Tridentine] rite of the Roman Mass than that of any other Protestant church."<ref name="Thuringer1965">{{cite news |author1=Rune P. Thuringer |title=Swedish Lutheran Liturgy Close to Rome's |access-date=25 May 2025 |publisher=[[The Catholic Advocate]] |date=11 March 1965|url=https://thecatholicnewsarchive.org/?a=d&d=ca19650311-01.2.51&e=-------en-20--1--txt-txIN--------}}</ref>

== Different levels of solemnity of celebration ==
There are various forms of solemnity of celebration of the Tridentine Mass:
* [[Papal Mass]] ([[Latin (language)|Latin]]: ''Missa Pāpālis''): celebrated by the [[Pope]], served by a [[cardinal-bishop]] assisting priest, the [[Apostolic Deacon]], more [[cardinal-deacon]]s, and a [[greek-catholic]] deacon and subdeacon, in Latin and [[Greek language|Greek]], with many unique traditions and [[vestments]]. It is a higher form derivative of the pontifical high mass given the pope's position as the [[Pontifex maximus]].
* [[Pontifical High Mass]] ([[Latin (language)|Latin]]: ''Missa pontificalis''): celebrated by a [[bishop]] accompanied by an assisting priest, [[deacon]], [[subdeacon]], [[thurifer]], acolytes and other ministers, under the guidance of a priest acting as Master of Ceremonies. Most often the specific parts assigned to deacon and subdeacon are performed by priests. The parts that are said aloud are all chanted, except that the Prayers at the Foot of the Altar, which before the reform of Pope Pius V were said in the sacristy, are said quietly by the bishop with the deacon and the subdeacon, while the choir sings the Introit. The main difference between a pontifical and an ordinary High Mass is that the bishop remains at his cathedra almost all the time until the offertory.
* [[Solemn Mass|Solemn or High Mass]] ([[Latin (language)|Latin]]: ''Missa solemnis''): offered by a priest accompanied by a deacon and subdeacon and the other ministers mentioned above.
* [[Missa Cantata]] ([[Latin (language)|Latin]] for "sung mass"): celebrated by a priest without deacon and subdeacon, and thus a form of Low Mass, but with some parts (the three variable prayers, the Scripture readings, Preface, Pater Noster, and Ite Missa Est) sung by the priest, and other parts (Introit, Kyrie, Gloria, Gradual, Tract or Alleluia, Credo, Offertory Antiphon, Sanctus and Benedictus, Agnus Dei, and Communion Antiphon) sung by the choir. Incense may be used exactly as at a Solemn Mass with the exception of incensing the celebrant after the Gospel which is not done.
* [[Low Mass]] ([[Latin (language)|Latin]]: ''Missa privata''): the priest sings no part of the Mass, though in some places a choir or the congregation sings, during the Mass, hymns not always directly related to the Mass. Note: the term ''missa privata'' was discouraged in 1962 for the misunderstanding of ''privata'' to mean private/non-public rather than 'deprived' of the fullness of ceremony.<ref>Rubricae Generales Missalis Romani De Anno MCMLXII point 269</ref>

In its article "The Liturgy of the Mass", the 1917 ''[[Catholic Encyclopedia]]'' describes how, when [[concelebration]] ceased to be practised in Western Europe, Low Mass became distinguished from [[Solemn Mass|High Mass]]:<ref name=":2">{{CathEncy|wstitle=Liturgy of the Mass}}</ref>

:The separate celebrations then involved the building of many altars in one church and the reduction of the ritual to the simplest possible form. The deacon and subdeacon were in this case dispensed with; the celebrant took their part as well as his own. One server took the part of the choir and of all the other ministers, everything was said instead of being sung, the incense and kiss of peace were omitted. So we have the well-known rite of low Mass (''missa privata''). This then reacted on high Mass (''missa solemnis''), so that at high Mass too the celebrant himself recites everything, even though it be sung by the deacon, subdeacon, or choir.

On the origin of the "''Missa Cantata''", the same source gives the following information about the Tridentine concept at the time:<ref name=":2"/>

:high Mass is the norm; it is only in the complete rite with deacon and subdeacon that the ceremonies can be understood. Thus, the rubrics of the [[Ordinary of the Mass]] always suppose that the Mass is high. Low Mass, said by a priest alone with one server, is a shortened and simplified form of the same thing. Its ritual can be explained only by a reference to high Mass. For instance, the celebrant goes over to the north side of the altar to read the Gospel, because that is the side to which the deacon goes in procession at high Mass; he turns round always by the right, because at high Mass he should not turn his back to the deacon and so on. A sung Mass (''missa Cantata'') is a modern compromise. It is really a low Mass, since the essence of high Mass is not the music but the deacon and subdeacon. Only in churches which have no ordained person except one priest, and in which high Mass is thus impossible, is it allowed to celebrate the Mass (on Sundays and feasts) with most of the adornment borrowed from high Mass, with singing and (generally) with incense.

A ''[[Missa brevis]]'' is a musical setting of a Mass where the choir and musicians do not perform some parts of the Ordinary of the Mass they potentially could, such as the Gloria or Creed. This is not related to the distinctions above.

== Revision of the Roman Missal ==
[[Pius XII]] began in earnest the work of revising the Roman Missal with a revision of the rites of Holy Week, which, after an experimental period beginning in 1951, was made obligatory in 1955.

On 4 December 1963, the [[Second Vatican Council]] decreed in Chapter II of its Constitution on the Sacred Liturgy ''[[Sacrosanctum Concilium]]'':<ref>{{Cite web|url=http://www.ewtn.com/library/COUNCILS/v2litur.htm|title=Constitution on the Sacred Liturgy|access-date=2004-08-07|archive-date=2004-08-03|archive-url=https://web.archive.org/web/20040803231514/http://www.ewtn.com/library/COUNCILS/V2LITUR.HTM|url-status=dead}}</ref>
<blockquote>[T]he rite of the Mass is to be revised ... the rites are to be simplified, due care being taken to preserve their substance. Parts which with the passage of time came to be duplicated, or were added with little advantage, are to be omitted. Other parts which suffered loss through accidents of history are to be restored to the vigor they had in the days of the holy Fathers, as may seem useful or necessary. The treasures of the Bible are to be opened up more lavishly so that a richer fare may be provided for the faithful at the table of God's word ... A suitable place may be allotted to the vernacular in Masses which are celebrated with the people ... communion under both kinds may be granted when the bishops think fit...as, for instance, to the newly ordained in the Mass of their sacred ordination, to the newly professed in the Mass of their religious profession, and to the newly baptized in the Mass which follows their baptism...</blockquote>

The instruction ''Inter Oecumenici'' of 26 September 1964 initiated the application to the Mass of the decisions that the Council had taken less than a year before. Permission was given for use, only in Mass celebrated with the people, of the vernacular language, especially in the Biblical readings and the reintroduced Prayers of the Faithful, but, "until the whole of the Ordinary of the Mass has been revised", in the chants (Kyrie, Gloria, Creed, Sanctus, Agnus Dei, and the entrance, offertory and communion antiphons) and in the parts that involved dialogue with the people, and in the Our Father, which the people could now recite entirely together with the priest. Most Episcopal Conferences quickly approved interim vernacular translations, generally different from country to country, and, after having them confirmed by the Holy See, published them in 1965. Other changes included the omission of Psalm 43 (42) at the start of Mass and the Last Gospel at the end, both of which Pope Pius V had first inserted into the Missal (having previously been private prayers said by the priest in the sacristy), and the Leonine Prayers of [[Pope Leo XIII]]. The [[Canon of the Mass]], which continued to be recited silently, was kept in Latin.

Three years later, the instruction ''Tres abhinc annos''<ref>{{Cite web |url=http://www.adoremus.org/TresAbhinc.html |title=''Tres abhinc annos'' |access-date=2006-09-01 |archive-date=2013-09-27 |archive-url=https://web.archive.org/web/20130927115159/http://www.adoremus.org/TresAbhinc.html |url-status=dead }}</ref> of 4 May 1967 gave permission for use of the vernacular even in the Canon of the Mass, and allowed it to be said audibly and even, in part, to be chanted; the vernacular could be used even at Mass celebrated without the people being present. Use of the [[maniple (vestment)|maniple]] was made optional, and at three ceremonies at which the [[cope]] was previously the obligatory vestment the [[chasuble]] could be used instead.

[[Pope Paul VI]] continued implementation of the Council's directives, ordering with [[Apostolic Constitution]] ''Missale Romanum''<ref>{{Cite web|url=https://www.papalencyclicals.net/paul06/p6missal.htm|title=Missale Romanum|date=April 3, 1969}}</ref> of Holy Thursday, 3 April 1969, publication of a new official edition of the Roman Missal, which appeared (in Latin) in 1970.

===Opposition to latest revisions===
Some [[Traditionalist Catholic]]s reject to a greater or lesser extent the changes made since 1950. None advocate returning to the original (1570) form of the liturgy, though some may perhaps wish a re-establishment of its form before Pius X's revision of the rubrics in 1911. Some are critical of the 1955 changes in the liturgy of Palm Sunday and the Easter Triduum and in the liturgical calendar (see [[General Roman Calendar of Pope Pius XII]]), and instead use the [[General Roman Calendar as in 1954]], such as the [[Society of Saint Pius V]] (SSPV) and [[Istituto Mater Boni Consilii]] (IMBC). Others accept the 1955 changes by Pius XII, but not those of Pope John XXIII, such as the [[Congregation of Mary Immaculate Queen]] (CMRI). Others again, in accordance with the authorization granted by Pope Benedict XVI in ''[[Summorum Pontificum]]'', use the Missal and [[General Roman Calendar of 1960|calendar]] as it was in 1962. They argue that many of the changes made to the liturgy in 1955 and onward were largely the work of liturgist [[Annibale Bugnini]], whom traditionalists say was more interested in innovation than the preservation of the [[Sacred tradition|apostolic traditions]] of the Church.<ref>{{Cite book |last=László |first=Dobszay |url= |title=The Bugnini-liturgy and the reform of the reform |date=2003 |publisher=Catholic Church Music Associates |oclc=909770654}}</ref><ref>{{Cite book |last=Davies |first=Michael |url= |title=Liturgical time bombs in Vatican II : the destruction of Catholic faith through changes in Catholic worship |date=2013 |isbn=978-1-61890-433-1 |location=Charlotte, North Carolina |oclc=956997771}}</ref>

Some Catholics contend that, unlike earlier reforms, the revision of 1969–1970 which replaced the Tridentine Mass with the [[Mass of Paul VI|Mass of Pope Paul VI]] represented a major break with the past. They consider that the content of the revised liturgy is, in Catholic terms, seriously deficient and defective; a small minority of these Catholics hold that it is displeasing to God, and that no Catholic should attend it.{{efn|name=popebenedictxvi}}<ref>{{cite web |title=Why the SSPX uses the 1962 missal |url=https://sspx.org/en/why-sspx-uses-1962-missal-30158 |website=SSPX - District of the USA}}</ref>

When a preliminary text of two of the sections of the revised Missal was published in 1969, Archbishop [[Marcel Lefebvre]] (who later established [[Society of Saint Pius X]]) gathered a group of twelve theologians, who, under his direction,<ref>{{Cite web|title=A Short History of the SSPX|url=http://www.sspx.org/SSPX_FAQs/appendix_iii_history_1.htm|url-status=dead|archive-url=https://web.archive.org/web/20091015194912/http://www.sspx.org/SSPX_FAQs/appendix_iii_history_1.htm|archive-date=October 15, 2009}}</ref> wrote a study of the text.

From the 1960s onwards, Western countries have experienced a drop in Mass attendance. For example, in the United States, 75% of Catholics attended church weekly in 1958, declining to 25% attending by 2002;<ref name=Jones2003/> another study suggests a peak weekly attendance of 72% in 1959–60.<ref>{{cite journal|title=The Center Doesn't Hold: Church Attendance in the United States, 1940-1984|first1=Michael|last1=Hout|first2=Andrew M.|last2=Greeley|journal=[[American Sociological Review]]|date=June 1987|jstor=2095353|doi=10.2307/2095353|volume=52|number=3|page=326}}</ref> Western countries also saw a decline in seminary enrollments and in the number of priests (in the United States, from 1,575 ordinations in 1954 to 450 in 2002), and a general erosion of belief in the doctrines of the Catholic faith. Opponents of the revision of the Mass liturgy argue, citing opinion poll evidence in their support, that the revision contributed to this decline.<ref name=Jones2003>Jones, Kenneth C. (January 2003).

==Attitudes of Popes since the Second Vatican Council==
{{Further|Preconciliar rites after the Second Vatican Council}}

===Pope Paul VI===
Following the introduction of the [[Mass of Paul VI]] in 1969–1970, the [[Holy See]] granted a significant number of permissions for the use of the former liturgy. For example, elderly priests were not required to switch to celebrating the new form. In England and Wales, occasional celebrations of the Tridentine Mass were allowed in virtue of what became known as the "[[Agatha Christie indult]]". There was no general worldwide legal framework allowing for the celebration of the rite. Following the rise of the [[Traditionalist Catholic]] movement in the 1970s, Pope Paul VI reportedly declined to liberalise its use further on the grounds that it had become a politically charged symbol associated with opposition to his policies.<ref>{{cite book | last1 = Collins| first1 = Roger | title = Keepers of the Keys of Heaven: A History of the Papacy | url = https://archive.org/details/keepersofkeysofh0000coll| url-access = registration| publisher = Basic Books | year = 2009 | pages = [https://archive.org/details/keepersofkeysofh0000coll/page/488 488–489]| isbn = 978-0-465-01195-7}}</ref>

===Pope John Paul II===
In 1984, the [[Holy See]] sent a letter known as ''[[Quattuor abhinc annos]]'' to the presidents of the world's [[Episcopal Conference]]s. This document empowered diocesan bishops to authorise, on certain conditions, celebrations of the Tridentine Mass for priests and laypeople who requested them.<ref>{{Cite web |url=http://www.adoremus.org/Quattuorabhincannos.html |title=English translation of ''Quattuor abhinc annos'' |access-date=2004-09-01 |archive-date=2004-08-25 |archive-url=https://web.archive.org/web/20040825175334/http://www.adoremus.org/Quattuorabhincannos.html |url-status=dead }}</ref> In 1988, following the excommunication of Archbishop [[Marcel Lefebvre]] and the four bishops consecrated by him, the Pope issued the ''[[motu proprio]]'' ''[[Ecclesia Dei]]'', which stated that "respect must everywhere be shown for the feelings of all those who are attached to the Latin liturgical tradition". The Pope urged bishops to give "a wide and generous application" to the provisions of ''Quattuor abhinc annos'', and established the [[Pontifical Commission Ecclesia Dei|Pontifical Commission ''Ecclesia Dei'']] to oversee relations between Rome and Traditionalist Catholics.<ref>{{Cite web|url=https://www.vatican.va/content/john-paul-ii/en/motu_proprio/documents/hf_jp-ii_motu-proprio_02071988_ecclesia-dei.html|title=Ecclesia Dei (2 July 1988) &#124; John Paul II|website=www.vatican.va}}</ref>

===Pope Benedict XVI===
As a [[cardinal (Catholicism)|cardinal]], Joseph Ratzinger was regarded as having a particular interest in the liturgy, and as being favourable towards the pre-Vatican II Mass.<ref>{{Cite book|url=https://books.google.com/books?id=ILTWCgAAQBAJ&q=election+Benedict+%22pre-Vatican+II+Mass%22&pg=PT107|title=Legacy of Vatican II, The|first1=Massimo|last1=Faggioli|first2=Andrea Vicini|last2=SJ|date=May 5, 2015|publisher=Paulist Press|isbn=9780809149223|via=Google Books}}</ref> Before his election he celebrated it on a number of occasions.<ref>{{cite web | url=https://www.ncregister.com/interview/benedict-xvi-and-tradition-an-analysis-of-his-approach-to-the-traditional-liturgy | title=Benedict XVI and Tradition: An Analysis of His Approach to the Traditional Liturgy | date=9 January 2023 }}</ref> He criticized the erratic way in which, contrary to official policy, many priests celebrated the post-Vatican II form.<ref>[http://www.barroux.org/docum/RATZINGER_REF.pdf Preface to the French edition of ''Die Reform der Römischen Liturgie'' by Klaus Gamber] {{Webarchive|url=https://web.archive.org/web/20090327105312/http://www.barroux.org/docum/RATZINGER_REF.pdf |date=2009-03-27 }}; [https://web.archive.org/web/20040208002309/http://www.latin-mass-society.org/ratzshow.htm partial English translation]; cf.

In September 2006, the [[Pontifical Commission Ecclesia Dei|Pontifical Commission ''Ecclesia Dei'']] established the [[Institute of the Good Shepherd]], made up of former members of the [[Society of St. Pius X]], in Bordeaux, France, with permission to use the Tridentine liturgy.<ref>Brian Mershon, "New French traditionalist priestly society founded", ''The Wanderer'', September 18, 2006.</ref> This step was met with some discontent from French clergy, and thirty priests wrote an open letter to the Pope.<ref>"French clerics rebel on Latin Mass", ''The Conservative Voice'', October 29, 2006</ref> In line with its previous stance, the Society of St Pius X rejected the move.<ref>{{Cite web |url=http://www.laportelatine.org/accueil/communic/2006/institutbonpasteur/institut.php |title=Communiqué de la Fraternité Sacerdotale Saint Pie X |access-date=2007-03-11 |archive-url=https://web.archive.org/web/20071027124243/http://www.laportelatine.org/accueil/communic/2006/institutbonpasteur/institut.php |archive-date=2007-10-27 |url-status=dead }}</ref>

Following repeated rumours that the use of the Tridentine Mass would be liberalised, the Pope issued a ''[[motu proprio]]'' called ''[[Summorum Pontificum]]'' on 7 July 2007,<ref>{{Cite web |url=http://www.sanctamissa.org/en/resources/summorum-pontificum.html |title=Text of the motu proprio ''Summorum Pontificum'' in Latin and English |access-date=2008-12-19 |archive-date=2012-10-10 |archive-url=https://web.archive.org/web/20121010043928/http://www.sanctamissa.org/en/resources/summorum-pontificum.html |url-status=dead }}</ref> together with an accompanying letter to the world's bishops.<ref name="Pope_Letter">{{cite journal |author = Benedict XVI | author-link = Pope Benedict XVI | title = Letter of His Holiness Benedict XVI to the Bishops on the occasion of the publication of the Apostolic Letter "motu proprio data" ''Summorum Pontificum'' on the use of the Roman liturgy prior to the reform of 1970 | publisher = Libreria Editrice Vaticana | date = 2007-07-07 | url = https://www.vatican.va/holy_father/benedict_xvi/letters/2007/documents/hf_ben-xvi_let_20070707_lettera-vescovi_en.html | access-date = 2008-03-24 }}</ref> The declaring that "the Roman Missal promulgated by Paul VI is the ordinary expression of the ''lex orandi'' (law of prayer) of the Catholic Church of the Latin rite.

In his letter to the Bishops he said: "It is not appropriate to speak of these two versions of the Roman Missal as if they were 'two Rites'. Rather, it is a matter of a twofold use of one and the same rite."</ref> He further stated that "the 1962 Missal ... was never juridically abrogated". He replaced with new rules those of ''Quattuor Abhinc Annos'' on use of the older form: essentially, authorization for using the 1962 form for parish Masses and those celebrated on public occasions such as a wedding is devolved from the local bishop to the priest in charge of a church, and "any priest of the Latin rite" may use the 1962 Roman Missal in "Masses celebrated without the people", a term that does not exclude attendance by other worshippers, lay or clergy.<ref>Indeed, "Mass should not be celebrated without a minister or at least one of the faithful, except for a just and reasonable cause" ([http://www.acbc.catholic.org.au/documents/200707031933.pdf General Instruction of the Roman Missal, 254] {{webarchive|url=https://web.archive.org/web/20080720091216/http://www.acbc.catholic.org.au/documents/200707031933.pdf |date=2008-07-20 }}). Masses celebrated without the people were once called "private Masses", a term that fell out of favour in the mid-twentieth century: the 1960 [[Code of Rubrics]], which preceded the Second Vatican Council, declared: "The most sacred Sacrifice of the Mass celebrated according to the rites and regulations is an act of public worship offered to God in the name of Christ and the Church. Therefore, the term 'private Mass' should be avoided" ([http://www.sanctamissa.org/en/resources/books-1962/missale-romanum-1962.pdf Rubricae Generales Missalis Romani] {{Webarchive|url=https://web.archive.org/web/20200215054059/https://sanctamissa.org/en/resources/books-1962/missale-romanum-1962.pdf |date=2020-02-15 }}, 269).

===Pope Francis===
Pope Francis on 16 July 2021 released an [[Ecclesiastical letter#Letters of the popes in modern times|Apostolic Letter]] ''[[Motu Proprio]]'', ''[[Traditionis custodes]]'', on the use of the Roman Liturgy prior to the Reform of 1970. In ''Traditionis custodes'', the Pope says "the liturgical books promulgated by Saint Paul VI and Saint John Paul II, in conformity with the decrees of Vatican Council II, are the unique expression of the ''[[lex orandi]]'' of the Roman Rite". He also greatly restricted the use of the Tridentine Mass.<ref name=":0">{{Cite web|title=Apostolic Letter issued "Motu proprio" by the Supreme Pontiff Francis "Traditionis custodes" on the use of the Roman Liturgy prior to the Reform of 1970, 16 July 2021 {{!}} Francis|url=https://www.vatican.va/content/francesco/en/motu_proprio/documents/20210716-motu-proprio-traditionis-custodes.html|access-date=2021-07-17|website=www.vatican.va}}</ref>

Pope Francis added that it is the exclusive competence of the [[local bishop]] to authorize the use of the 1962 Roman Missal in his diocese, according to the guidelines of the Apostolic See.<ref name=":0"/>

Pope Francis expressed to the Bishops of the world in his letter accompanying the motu proprio that there is a need in "due time" for those who are attached to the 1962 Mass to return to the celebration of the Mass of Paul VI.<ref>{{Cite web|title=Letter of the Holy Father to the Bishops of the whole world, that accompanies the Apostolic Letter Motu Proprio data "Traditionis custodes" (16 July 2021) {{!}} Francis|url=https://www.vatican.va/content/francesco/en/letters/2021/documents/20210716-lettera-vescovi-liturgia.html|access-date=2022-01-05|website=www.vatican.va}}</ref>

In June 2022, Pope Francis issued the Apostolic Letter ''Desiderio Desideravi'', where he stated that he did not believe the 1962 Missal was the path forward for the Church, insisting that the Church could not "go back to the ritual form which the Council Fathers sought the need to reform".<ref>{{Cite web |title='Desiderio Desideravi': Initial Impressions of Pope Francis' New Document on the Mass |url=https://www.ncregister.com/news/desiderio-desideravi-initial-impressions-of-pope-francis-new-document-on-the-mass |access-date=2022-07-20 |website=NCR |date=29 June 2022 }}</ref>

In February 2023, Pope Francis issued a rescript, clarifying that bishops must obtain authorization from the [[Holy See]] before granting permission for parish churches to be used for Eucharistic celebrations with the preconciliar rite and before allowing priests ordained after 16 July 2021 to use the 1962 Roman Missal.<ref>{{Cite web |date=2023-02-21 |title=Pope Francis clarifies two points of 'Traditionis custodes' |url=https://www.vaticannews.va/en/pope/news/2023-02/pope-francis-traditionis-custodes-rescript-bishops.html |access-date= |website=[[Vatican News]] }}</ref>

===Pope Leo XIV===
While Pope Leo XIV has not so far commented on celebrations of the Tridentine Mass, it was reported in September 2025 that he had granted permission for a celebration of that Mass in [[St. Peter's Basilica]] to be held at the end of the following month, as part of an annual traditionalist pilgrimage to Rome.

=== Present regulations and practice ===

The regulations set out in ''[[Traditionis custodes]]'' provide that:<ref name=":0"/>
* The bishop of the diocese is the sole authority to decide whether the celebration of Mass according to the 1962 Roman Missal may take place in his diocese. He must abide by the following norms:
**The bishop must decide the locations and times when Mass according to the 1962 rubrics may take place. This cannot occur within [[parochial church]]es, nor can the bishop erect new personal parishes dedicated to the celebration of Mass according to the 1962 Missal. 
**The bishop must ensure that the existing communities that celebrate Mass according to the 1962 rubrics are effective for the spiritual growth of his people, and he has the option to revoke the permissions given to these communities. He may not authorize the establishment of new groups that gather for celebration according to the 1962 Roman Missal.
**The bishop should appoint a priest to act as a delegate for the pastoral care of the groups of the faithful attached to the 1962 liturgical rites. The priest must understand the Missal of 1962 well, must be well-versed in Ecclesiastical Latin, and must exhibit pastoral charity and a desire for ecclesial communion.
*Priests ordained before the publication of ''Traditionis custodes'' (16 July 2021) who celebrated Mass according to the 1962 Missal before the publication of ''Traditionis custodes'' should request permission from the bishop of the diocese to continue to celebrate Mass according to the 1962 rubrics.
*Priests ordained after the publication of ''Traditionis custodes'' must submit a formal request to the bishop of the diocese in order to gain permission to celebrate Mass according to the 1962 Roman Missal. The bishop must then consult the [[Holy See]] before the bishop grants permission to the priest.
*The scriptural readings in a Mass celebrated according to the 1962 Missal are to be proclaimed in the vernacular according to the translation approved by the respective Episcopal Conference.
*Communities belonging to [[institutes of consecrated life]] and [[society of apostolic life|societies of apostolic life]] which use the 1962 Missal for conventual or "community" celebration in their oratories fall under the competence of the [[Congregation for Institutes of Consecrated Life and Societies of Apostolic Life]], which has the authority to grant and revoke permission to celebrate Mass according to the 1962 Missal.

The ''motu proprio [[Traditionis custodes]]'' abrogates all previous norms, instructions, permissions and customs that do not conform to it.<ref>Article 8 of [https://www.vatican.va/content/francesco/en/motu_proprio/documents/20210716-motu-proprio-traditionis-custodes.html Traditionis custodes]</ref>

In December 2021, additional restrictions and guidelines were issued by the [[Congregation for Divine Worship and the Discipline of the Sacraments]] in the form of a ''[[Responsa]] ad dubia:''<ref>{{Cite web|title=Responsa ad dubia on certain provisions of the Apostolic Letter Traditionis custodes issued "Motu Proprio" by the Supreme Pontiff Francis (4 December 2021)|url=https://www.vatican.va/roman_curia/congregations/ccdds/documents/rc_con_ccdds_doc_20211204_responsa-ad-dubia-tradizionis-custodes_en.html|access-date=2022-01-04|website=www.vatican.va}}</ref>
* if a non-[[parish church]], [[Oratory (worship)|oratory]] or [[chapel]] cannot be found for a group to gather to celebrate the Mass according to the 1962 Missal, the [[diocesan bishop]] can ask the [[Holy See]] for permission to use a parish church; it should not be listed in the parish schedule and when a non-parish church, oratory or chapel becomes available, the permission to celebrate the Mass in the parish church will be withdrawn.
* The diocesan bishop is only authorized to grant permission to personal parishes dedicated to the celebration of the 1962 Missal, to be able to celebrate the sacraments of [[Baptism]], [[Sacrament of Penance|Reconciliation]], [[Marriage in the Catholic Church|Matrimony]] and [[Anointing of the Sick in the Catholic Church|Extreme Unction]] according to the pre-Vatican II [[Roman Ritual]].
* The diocesan bishop is not authorized to grant permission for the use of the [[Roman Pontifical|Pontificale Romanum]] (the Pontifical Missal) issued in 1962. This also means that the sacraments of [[Holy orders in the Catholic Church|Holy Orders]] and [[Confirmation in the Catholic Church|Confirmation]] may only be celebrated in the post-Vatican II form. 
* In order for a priest to be granted permission to celebrate the Mass according to the Missal of 1962, he must recognize the validity and legitimacy of [[concelebration]] and is not to refuse to concelebrate at the diocesan [[Chrism Mass]].
* No vernacular lectionaries may be published that reproduce the cycle of readings from the 1962 Rite.
* The faculty to celebrate according to the 1962 missal, granted by a diocesan bishop to a priest, is restricted to the territory of that diocese.
* Deacons and [[instituted minister]]s participating in the celebration of Mass according to the 1962 missal, must have permission from the diocesan bishop to do so.
* A priest who has been granted faculties to celebrate the 1962 missal is not permitted to celebrate both the Mass according to the 1962 missal and the post-Vatican II missal on the same day.

In December 2021, in an interview with the ''[[National Catholic Register]]'', [[Arthur Roche]], the Prefect for the Congregation in charge of the implementation of ''Traditionis custodes'', reiterated Pope Francis' statement that the Mass according to the Missal promulgated by Paul VI and John Paul II, is "the unique expression of the lex orandi of the Roman Rite". Roche also emphasized that "the liturgy is never simply a matter of personal tastes or preference" and that the lex orandi is "determined by the Church and not individual members". Roche also stated that continuing to allow the celebration of Mass according to the Tridentine form was a concession and that the promotion of the Tridentine Mass has "been curtailed".<ref>{{Cite web|title=Archbishop Roche on 'Traditionis Custodes' and Its Guidelines: 'The Liturgical Possibilities Are in Place'|url=https://www.ncregister.com/interview/archbishop-roche-on-traditionis-custodes-and-its-guidelines-the-liturgical-possibilities-are-in-place|access-date=2022-01-05|website=NCR|date=23 December 2021 }}</ref>

In February 2022, the [[Priestly Fraternity of Saint Peter]], a [[society of apostolic life]] dedicated to the celebration of the Traditional Liturgy, was granted full permission to celebrate the Traditional Mass, Breviary, Sacraments and the Pontifical Missal. The permission is restricted to the Fraternity's churches and oratories, unless the local ordinary grants permission for priests of the fraternity to celebrate elsewhere in the Diocese, with the exception of private masses.<ref>{{Cite web |last=CNA |title=FSSP says Pope Francis has issued decree confirming its use of 1962 liturgical books |url=https://www.catholicnewsagency.com/news/250438/fssp-says-pope-francis-has-issued-decree-confirming-its-use-of-1962-liturgical-books |access-date=2022-02-26 |website=Catholic News Agency }}</ref>

On a few recent occasions Roman Catholic prelates have used this variant as an extraordinary form of celebrating Mass.

{{efn|name=popebenedict|Pope Benedict spoke of it instead as "an" extraordinary form.

{{efn|name=popebenedictxvi|Pope Benedict XVI has declared this contention unfounded, writing: "There is no contradiction between the two editions of the Roman Missal. In the history of the liturgy there is growth and progress, but no rupture. [...] Needless to say, in order to experience full communion, the priests of the communities adhering to the former usage cannot, as a matter of principle, exclude celebrating according to the new books. The total exclusion of the new rite would not in fact be consistent with the recognition of its value and holiness" ([https://www.vatican.va/holy_father/benedict_xvi/letters/2007/documents/hf_ben-xvi_let_20070707_lettera-vescovi_en.html Letter] to the Bishops on the occasion of the publication of the Apostolic Letter ''motu proprio data'' [[Summorum Pontificum]]).}}

{{efn|name=theygave|They gave responses to "[[Kyrie eleison]]", "[[Dominus vobiscum]]", "Per omnia saecula saeculorum", the [[Gospel]] reading, the "[[Orate Fratres]]", "[[Sursum Corda]]", "Gratias agamus Domino Deo nostro", the conclusion of the [[Lord's Prayer]], the "Pax Domini sit semper vobiscum" and the "[[Ite Missa est]]"}}

{{efn|name=similarlyclementviii|Similarly, Clement VIII did not juridically abrogate the Missal of Pius V, nor did the other Popes who issued later typical editions of the Roman Missal before that of Paul VI (Urban VIII, Leo XIII, Benedict XV, John XXIII) juridically abrogate the previous editions. Even Pius V juridically abolished only those [[Latin liturgical rites#Regional Latin rites or uses|variants of the Roman Rite]] that had less than 200 years' antiquity.}}

{{efn|name=intheletter| In the letter to bishops by which he accompanied the ''motu proprio'' the Pope told them that the new regulations "do not in any way lessen your own authority and responsibility, either for the liturgy or for the pastoral care of your faithful." Cardinal Castrillón stated: "The Pope has not changed the Code of Canon Law. The bishop is the moderator of the liturgy in his own diocese. But the Apostolic See is entitled to shape the sacred liturgy of the universal Church. And a bishop must act in harmony with the Apostolic See and must guarantee the rights of every believer, including that of being able to attend the mass of Saint Pius V, as extraordinary form of the rite".(see {{cite web|url=http://www.30giorni.it/us/articolo.asp?id=15045 |title=30Days|date=June 2007|archive-url=https://web.archive.org/web/20070927013848/http://www.30giorni.it/us/articolo.asp?id=15045 |archive-date=2007-09-27 }}) }}
