when did the catholic church stop using latin
Latin Mass 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.[5] The term "Latin Mass" is sometimes applied to such celebrations, which in some places are part of the normal Sunday schedule.
Development of the Christian biblical canon In the wake of the Protestant Reformation, the Catholic canon was reaffirmed by the Catholic Church at the Council of Trent (1546), which provided "the first infallible and effectually promulgated pronouncement on the Canon" by the Roman Catholic Church.[2] The canons of the Church of England and English Calvinists were decided definitively by the Thirty-Nine Articles (1563) and the Westminster Confession of Faith (1647), respectively. The Synod of Jerusalem (1672) established additional canons that are widely accepted throughout the Orthodox Church.
