Western rites

The Roman Rite is the most common rite of worship used by the Catholic Church, with the Ordinary Form of the Roman Rite form of the Mass. Its use is found worldwide, originating in Rome and spreading throughout Europe, influencing and eventually supplanting local rites. The present ordinary form of Mass in the Roman Rite, found in the post-1969 editions of the Roman Missal, is usually celebrated in the local vernacular language, using an officially approved translation from the original text in Latin. An outline of its major liturgical elements can be found in the sidebar.

In 2007, Pope Benedict XVI affirmed the licitness of continued use of the 1962 Roman Missal as an "extraordinary form" (forma extraordinaria) of the Roman Rite, speaking of it also as an usus antiquior ("older use"), and issuing new more permissive norms for its employment. An instruction issued four years later spoke of the two forms or usages of the Roman Rite approved by the pope as the ordinary form and the extraordinary form ("the forma ordinaria " and "the forma extraordinaria ").

The 1962 edition of the Roman Missal, published a few months before the Second Vatican Council opened, was the last that presented the Mass as standardized in 1570 by Pope Pius V at the request of the Council of Trent and that is therefore known as the Tridentine Mass. Pope Pius V's Roman Missal was subjected to minor revisions by Pope Clement VIII in 1604, Pope Urban VIII in 1634, Pope Pius X in 1911, Pope Pius XII in 1955, and Pope John XXIII in 1962. Each successive edition was the ordinary form of the Roman Rite Mass until superseded by a later edition. When the 1962 edition was superseded by that of Paul VI, promulgated in 1969, its continued use at first required permission from bishops; but Pope Benedict XVI 's 2007 motu proprio Summorum Pontificum allowed free use of it for Mass celebrated without a congregation and authorized parish priests to permit, under certain conditions, its use even at public Masses. Except for the scriptural readings, which Pope Benedict allowed to be proclaimed in the vernacular language, it is celebrated exclusively in liturgical Latin. These permissions were largely removed by Pope Francis in 2021, who issued the motu proprio Traditionis custodes to emphasize the Ordinary Form as promulgated by Popes Paul VI and John Paul II.

Since 2014, clergy in the small personal ordinariates set up for groups of former Anglicans under the terms of the 2009 document Anglicanorum Coetibus are permitted to use a variation of the Roman Rite called "Divine Worship" or, less formally, "Ordinariate Use", which incorporates elements of the Anglican liturgy and traditions, an accommodation protested by Anglican leaders.

In the Archdiocese of Milan, with around five million Catholics the largest in Europe, Mass is celebrated according to the Ambrosian Rite. Other Latin Church rites include the Mozarabic and those of some religious institutes. These liturgical rites have an antiquity of at least 200 years before 1570, the date of Pope Pius V's Quo primum, and were thus allowed to continue.
