The term "Latin Mass" is sometimes applied to such celebrations, which in some places are part of the normal Sunday schedule.
Historically speaking, "Latin Mass" can be applied also to the various forms of Pre-Tridentine Mass from about the year 190 of Pope Victor, when the Church in Rome changed from Greek to Latin.
However, in Dalmatia and parts of Istria in Croatia, the liturgy was celebrated in Church Slavonic, and authorisation for use of this language was extended to some other Slavic regions between 18.
There "Tridentine Mass" was not synonymous with "Latin Mass".
Some priests and communities continue to use non-Roman-Rite liturgies that have been generally abandoned, such as the Carmelite Rite and the Dominican Rite, celebrating them in Latin.
Celebration in Latin of such rites is sometimes referred to as "Latin Mass".
Episcopal conferences were to decide, with the consent of the Holy See, what other parts, if any, of the Mass were to be celebrated in the vernacular.
Permissions were thus granted from 1967 onwards to celebrate most of the Tridentine Mass in vernacular languages, including the Canon.
Neither the Second Vatican Council nor the subsequent revision of the Roman Missal abolished Latin as the liturgical language of the Roman Rite: the official text of the Roman Missal, on which translations into vernacular languages are to be based, continues to be in Latin, and Latin can still be used in the celebration.
A Traditionalist Catholic periodical in the United States is entitled The Latin Mass, the Journal of Catholic Culture and Tradition.
Latin liturgical rites other than the Roman Rite have used Latin, and in some cases continue to do so.These include the Ambrosian Rite and the Mozarabic Rite.
