You seem to have a remarkable knowledge of the duplicity of early Christians in fabricating the Scriptures, putting words into Our Lord's mouth.
In esssence then we have no evidence that Jesus Christ said or did anything whilst on earth. Indeed we have only the testimony of Josephus and Pliny that He even existed.
From this then no one need believe then anything they read in the NT; about the life, the teaching, the passion, the death, the resurrection and ascension of Our Lord, and this on the say-so of an agnostic-atheist which some dumb University employs to teach Christian Scripture.
