The Catholic Answers

Christ, as the Founder of the Catholic Church, was of course a Catholic. But your conclusion does not follow. Many profess to believe in Christ, but do not accept the whole of His teaching. They are mistaken. Certainly the Anglican does not believe in the correct doctrines of Christ if the Baptist does. The Catholic Church alone teaches the complete doctrine of Christ, and the only way to become a Catholic is to submit to her teaching authority and disciplinary directions.
