when was the first time the word catholic was used
Catholic (term) The word catholic (with lowercase c; derived via Late Latin catholicus, from the Greek adjective καθολικός (katholikos), meaning "universal"[1][2]) comes from the Greek phrase καθόλου (katholou), meaning "on the whole", "according to the whole" or "in general", and is a combination of the Greek words κατά meaning "about" and ὅλος meaning "whole".[3][4] The term Catholic (usually written with uppercase C in English) was first used to describe the Christian Church in the early 2nd century to emphasize its universal scope. In the context of Christian ecclesiology, it has a rich history and several usages.
Latin Mass A further distancing between the concepts of "Tridentine Mass" and "Latin Mass" was brought about by the 1964 Instruction on implementing the Constitution on Sacred Liturgy of the Second Vatican Council, which laid down that "normally the epistle and gospel from the Mass of the day shall be read in the vernacular". 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.[3] Permissions were thus granted from 1967 onwards to celebrate most of the Tridentine Mass in vernacular languages, including the Canon.
