Then the CC wrote a book that contradicts its own doctrine.<quoted text>Amen. The CC agrees with that verse. It wrote it and put in the Bible.
"He is the head of the body, the church. He is the beginning, the firstborn from the dead, that in all things he himself might be preeminent."
This proves he started a Church and did not leave a book. But he knew he was going to heaven, and he left somebody as head of his Church, Peter.
From his own mouth. "You are Peter and I will build my Church on you."
God did the same in the OT. Always had a man on Earth to lead. Abraham, Moses, Isaac, David, etc.
It is called Authority. Without Authority you get chaos, Protestantism.
