I did read your post and I provided a few reasons for my disagreement.
Paul claimed that he did not receive any of his instructions from any human. He claimed that he spoke with no one for 3 years after his conviction regarding Jesus Christ, that he spent 14 years without making any contact with Jerusalem, and when he gave them his gospel message, they added nothing. He speaks quite contemptuously of them (James, Cephas, and John). When the 4th century Church at Rome decided which writings they would canonise (currently our NT), they wrote James out of the picture, even though he was Jesus' full brother and leader of the Jerusalem community.
Paul indicated that his teachings came directly to him from the Lord, without any human involvement. Either he is deluded, telling a lie, or he is honest.
Paul could not have read the Gospels since they were written after his death and re-edited during subsequent centuries. He created the ideas and others followed, some of which I mentioned in my previous response.
Did Paul invent Christianity?
