Hmmm... "Vulgate"... I think we may have had that one before... But I could also just be thinking back to my days in Catholic grade school and high school.
Ecclesiastical Latin (sometimes called Church Latin) is the Latin dialect as used in documents of the Roman Catholic Church and in its Latin liturgies. Though its pronunciation differs slightly from that of Classical Latin, it is not a distinct language or dialect, but only the Latin language used for ecclesiastical purposes, as the same language can be used also for commercial purposes, for purposes of invective, or recreation.
