Catholic (term)
The word catholic (derived via Late Latin catholicus, from the ancient Greek adjective καθολικός (katholikos) 'universal') comes from the Greek phrase καθόλου (katholou) 'on the whole, according to the whole, in general', and is a combination of the Greek words κατά (kata) 'about' and ὅλος (holos) 'whole'. The first known use of "Catholic" was by the Church Father Ignatius of Antioch in his Letter to the Smyrnaeans (circa 110 AD).
