The word catholic (derived via Late Latin catholicus, from the Greek adjective katholikos, meaning "universal") comes from the Greek phrase kath'holou, meaning "on the whole," "according to the whole" or "in general". 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."
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; liberal, having broad interests, or wide sympathies; or inclusive, inviting and containing strong evangelism.
The term has been incorporated into the name of the largest Christian communion, the Roman Catholic Church, which consists of 23 churches sui iuris, in full communion with the Bishop of Rome. The largest of these, the Latin Rite, consists of nearly 95% of the population of the Roman Catholic Church; the remaining 5% consist of the 22 Eastern Catholic Churches.
You know what my days used to be like? I just tested. Nobody murdered me. Or put me in a potato. Or fed me to birds. I had a pretty good life. And then you showed up. You dangerous, mute lunatic. So you know what? You win. Just go. Don't come back.
