[Elsie]

Christ told his Apostles to go “teach” not to write down all that He said.

But; He did NOT say (AFAIK) for them to 'teach' what He had NOT said!

[Steelfish]

So you don’t trust what His early disciples taught. Apparently you were there to know to know that they taught what He did not say. He gave them His authority. Surely, these chose the very books of the Bible you quote, and if you trust their authority on this, why doubt their authority on other matters?
