Go back to the Aramaic which Jesus' spoke (quite similar to Hebrew). It is easier there to identify when Jesus was speaking of the written (on stone) Law (10 Commandments) and when he was speaking of the Oral Law (laws other than the Ten). No, Paul did not run counter (go back to etymology and the Latin and Greek).
Luke (who was a companion and traveled with Paul) wrote about Paul's encounter with Jesus. Paul noted it as well. Both said it happened after the Resurrection. So what we have here is Luke writing at the time of this incident, and Paul, himself, confirming it.
Yes, you can say, "Luke CLAIMED in happened and Paul CLAIMED it happened. But I'll go one better. I, two thousand years later, CLAIM it did not happen."
Oh, and by the way: From the worldly point of view even at that time, no one was claiming Paul's presentation was "palatable".
I am not the one twisting and turning...merely someone who did a deep dive into researching languages, histories, and cultures. Why this determination on my part? When I was young my experience of God did not tally with the Old Testament, at least not the English translation of the Old Testament. That was when a Jew, whose first language was Hebrew, began helping me out. The Hebrew gives an entirely different picture of God and those times. The man helping me: Yes, he was a Jew who knew Old Testament scriptures like the back of his hand. He was also an atheist. Quite a combination...an atheist Jews and a Catholic person of faith.
I agree that you, like him, are an atheist. However, you don't know scripture even a particle as well as he.
