Paul was a Roman who was Saul and was magically transformed into Paul on his word alone.
Paul is, was, and will be, a liar. Just like the Nicene Council who turned Jesus, the humble teacher, into a god to solidify their power and control over the people.
You should study the history of the New Testament. Start with the Nicene Council. Realize these lovely folks threw out eye-witness accounts of Jesus to go with a Gospel written sixty years after his death as the earliest tome.
The Sermon on the Mount is Jesus, the humble teacher, calling on us all to find the Father.
He was murdered because he threatened the bad guys in charge.
There is nothing new under the sun and all is vanity.
