You made the claim and now you can’t prove it? You have no documentation to substantiate what you say? Wow! Fail!
Actually it is the protestant who makes a claim that contradicts centuries of belief and the clear words of Jesus in Scripture.
You say the Apostles did not believe what the others believed when Jesus made what He Himself called a shocking teaching.
Yet, Scripture does not say that anywhere.
So, that leaves you to prove your opinion.
