Saul was a bounty hunter of the Apostles and never even met Jesus. In Acts 8:1, Saul approved of the execution of Stephen and then went on to persecute the church (the little people).<quoted text> paul was a israelite from the tribe of benjamin.
Now somewhere on the Road to Damascus, Saul got a revelation. The Bible portrays him as "seeing the light." I see that as Saul as recognizing a business opportunity.
He changed his name to Paul, usurped Peter's authority as the "Rock of the Church" and proceeded to take all the possessions from the naive Christian cultists (Sapphire and Annanais in Acts 5.) Paul made communism the hipster thing to do (Acts 5:32 - 34) nearly 2000 years before Karl Marx.
The Romans may have crucified Jesus, the man, but it was Saul/Paul who corrupted the upstart Christian cult. This business was so profitable that it still survives to this day.
