Following the promulgation of the [[Mass of Paul VI|Missal of Paul VI]] in 1969-70, it was generally assumed that the 1962 edition had been abrogated, however some refused to adopt the new missal, most notably the [[Society of Saint Pius X]], created by [[Marcel Lefebvre]]. On 30 October 1971, [[Paul VI]] granted permission for use of the previous missal in England and Wales, in what became known as the [[Agatha Christie indult]]. On 3 October 1984, [[Pope John Paul II]] issued a letter known as ''[[Quattuor abhinc annos]]'' which extended the indult to bishops worldwide. 

In his [[motu proprio]] ''[[Summorum Pontificum]]'' of 7 July 2007, [[Pope Benedict XVI]] stated that the 1962 edition of the Roman Missal was never juridically abrogated and that it may be freely used by any priest of the [[Latin Church]] when celebrating Mass "without a congregation".<ref>{{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" (July 7, 2007) {{!}} BENEDICT XVI|website=w2.vatican.va|access-date=2019-06-14}}</ref> Use of the 1962 edition at Mass with a congregation is allowed, with the permission of the priest in charge of a church, for stable groups attached to this earlier form of the [[Roman Rite]], provided that the priest using it is "qualified to do so and not juridically impeded" (as for instance by suspension). Accordingly, many dioceses schedule regular Masses celebrated using the 1962 edition. 

In 2021, [[Pope Francis]], motivated by a desire to stave off what he perceived to be growing rejection of the Second Vatican Council developing from groups using the preconciliar rites, issued ''[[Traditionis custodes]]'' to restore the previous status quo of bishops having authority over the celebrations of Mass in the preconciliar Roman Rite. Francis stated in the letter that the current version of the Roman Rite ought to be regarded as the "unique expression of [its] ''[[lex orandi]]''."<ref name="sap_ue">{{cite web |last=Ferrone |first=Rita |date=November 17, 2021 |title=Discerning the Lex Orandi |url=https://crc.blog.fordham.edu/faith-religion/discerning-the-lex-orandi/ |access-date=May 2, 2022 |website=Sapientia |publisher=[[Fordham University]]}}</ref>

Several [[traditionalist Catholic|traditionalist]] fraternities in full communion with the Holy See are authorised to celebrate the Mass exclusively according to the 1962 version of the Missal: such groups include the [[Priestly Fraternity of Saint Peter]] (FSSP), the [[Institute of Christ the King Sovereign Priest]] (ICKSP), the [[Institute of the Good Shepherd]] (IBP) and the [[Personal Apostolic Administration of Saint John Mary Vianney]]. However in more recent years, limited indults have been granted to certain parishes for use of the [[Holy Week]] prior to the reforms of Pius XII.<ref>{{Cite web|url=http://www.windsorlatinmass.org/wtnews/180311.pdf|title=Tridentine Community News, 11 March 2018}}</ref>

The [[Society of Saint Pius X]] (FSSPX), which rejects the reforms of the [[Second Vatican Council]] and [[Canonical situation of the Society of Saint Pius X|is not in full communion with the Holy See]], exclusively celebrates the Mass according to the 1962 version of the Roman Missal. [[Sedevacantism|Sedevacantist]] and [[Sedeprivationism|sedeprivationist]] groups, which reject the Council and do not recognise any Pope since the Council as valid, also reject the 1962 version of the Missal, seeing it as contaminated by modernism as well and thus only celebrate Mass using the 1920 edition of the Missal, however there is a dispute among these groups, on the acceptance of the 1955 rubrics of the Paschal Triduum introduced by Pius XII: some groups, such as the [[Society of Saint Pius V]], the [[Donald Sanborn|Roman Catholic Institute]] and the [[Istituto Mater Boni Consilii]]) reject them, believing them to be the first step towards the post-Conciliar liturgical renovations;<ref>{{Cite journal |last=Sanborn |first=Donald |author-link=Donald Sanborn |date=2008 |title=Benedict XVI replaces the Good Friday prayer for the Jews in the '62 Missal |url=https://www.traditionalmass.org/images/articles/GenJews.pdf |journal=MHT Seminary Newsletter |quote=It should be recalled that what occasioned our 1983 split with them was the John XXIII Mass, i.e., the 1962 Missal. The reason why Archbishop Lefebvre insisted that all take this missal, reversing his previous position of permitting the pre-1955 rubrics, was that he was in very serious negotiations with Ratzinger to have his Fraternity absorbed into the Modernist religion. He himself told me personally that the Vatican would never accept that we use the pre-1955 rubrics, and I saw myself the documents regarding the dialogue between him and Ratzinger, in which the 1962 Missal was on the table as the missal which would be approved for use by the Fraternity.[...] In 1983, when the nine priests made a stand over the maintenance of the St. Pius X rubrics of the missal, calendar and breviary, few lay people understood the importance of it. The average lay person cannot distinguish the 1962 traditional Mass from the pre-1955 traditional Mass, which is the one we use. But there are significant differences. Liturgy speaks volumes through gesture and symbolism.}}</ref> others, such as the [[Congregation of Mary Immaculate Queen]] accept them, seeing them as a liturgical change by a valid Pope and, thus, binding to all Catholics.<ref>{{Cite journal |last=Radecki |first=Fr Dominic |year=2016 |title=The Liturgical Changes of Pope Pius XII: May Catholics Reject Laws Promulgated by a Legitimate Pope? |url=https://cmri.org/articles-on-the-traditional-catholic-faith/the-liturgical-changes-of-pope-pius-xii/ |journal=The Reign of Mary |issue=161}}</ref> However, the CMRI does not accept the modifications to the Roman Missal by Pope John XXIII as they don't recognise him as a valid pope.<ref>{{cite web | url=https://cmri.org/articles-on-the-traditional-catholic-faith/is-the-latin-mass-back/ | title=Is the Latin Mass Back? | date=11 April 2017 }}</ref>
