Where did the Catholics religion come from?

Answer 1

The Roman Catholic Religion originally came from Judaism. All the founding members of the Church were Jews. Our Blessed Lord, Himself, was a Jew, and His apostles were all Jews. The "Roman" part of it comes from the fact that the first Pope, Peter, went to Rome, which was the center of the civilized world at that point in history, and the Church has spread out from Rome to cover the world. "Roman" is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church. It is never used by the Catholic Church.
