Just googled and picked this up from wikipedia -
The word catholic (derived via Late Latin catholicus, from the Greek adjective καθολικός (katholikos), meaning "universal"[1][2]) comes from the Greek phrase καθόλου (kath'holou), meaning "on the whole," "according to the whole" or "in general", and is a combination of the Greek words κατά meaning "about" and όλος meaning "whole".[3][4] The word in English can mean either "including a wide variety of things; all-embracing" or "of the Roman Catholic faith." as "relating to the historic doctrine and practice of the Western Church."[5]
It 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. In non-ecclesiastical use, it derives its English meaning directly from its root, and is currently used to mean
universal or of general interest; or
liberal, having broad interests, or wide sympathies.[6]
inclusive, inviting and containing strong evangelism.
