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.
anno Domini On the continent of Europe, Anno Domini was introduced as the era of choice of the Carolingian Renaissance by the English cleric and scholar Alcuin in the late eighth century. Its endorsement by Emperor Charlemagne and his successors popularizing the use of the epoch and spreading it throughout the Carolingian Empire ultimately lies at the core of the system's prevalence. According to the Catholic Encyclopedia, popes continued to date documents according to regnal years for some time, but usage of AD gradually became more common in Roman Catholic countries from the 11th to the 14th centuries.[27] In 1422, Portugal became the last Western European country to switch to the system begun by Dionysius.[28] Eastern Orthodox countries only began to adopt AD instead of the Byzantine calendar in 1700 when Russia did so, with others adopting it in the 19th and 20th centuries.
