Many Christian traditions describe themselves as part of the catholic, or universal, church. On this site, Roman Catholic Church identifies the worldwide church in communion with the Bishop of Rome. The wording helps distinguish it from other communities that use Catholic language in their names or theology.
The abbreviation RCC is used occasionally in this collection as a concise reference. It does not imply that every Catholic community, parish or individual holds identical views.
