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.
History of the Catholic Church During the 11th century, the Eastâ€“West schism permanently divided Christianity.[85] It arose over a dispute on whether Constantinople or Rome held jurisdiction over the church in Sicily and led to mutual excommunications in 1054.[85] The Western (Latin) branch of Christianity has since become known as the Catholic Church, while the Eastern (Greek) branch became known as the Orthodox Church.[86][87] The Second Council of Lyon (1274) and the Council of Florence (1439) both failed to heal the schism.[88] Some Eastern churches have since reunited with the Catholic Church, and others claim never to have been out of communion with the pope.[87][89] Officially, the two churches remain in schism, although excommunications were mutually lifted in 1965.[90]
