Catholic Churches

The Catholic Churches form a denomination in Christianity and with about 1.3 billion believers worldwide are the largest Christian grouping. The Catholics are in turn divided into individual sub-churches. The Roman Catholic Church refers to the Latin Church (Western Church). There are also the Eastern Catholic Churches, which are again divided into Greek Catholic or Armenian Catholic Churches.

The head of the Catholic Church is the Pope with seat in the Vatican.
