The Founder of the Church is not subject to the Church He founded. Rather the Church He founded is subject to Him. And the Church of which the Bishop of Rome is supreme head on earth is the only Church which is so subject to the authority of Christ that it can truly be called His. From our point of view the test of communion with Rome became valid as a mark of identification only from the day that St. Peter, under divine guidance, definitely established his See at Rome.
