Only slightly joking there. He was Saul of Tarsus, a Jewish Pharisee and persecuted early Christians. He had a conversion and became an early Christian leader. He was one of the first to include gentiles in Christianity. Before it was mostly Jewish people well because Jesus was Jewish. The law breaking joke is that in a vision he was given the ok to eat all foods not just kosher ones, ie he broke religious laws at the time Edit: I misremembered, it was Peter who had the food vision not Paul. But I believe Peter also changed his name, yes he was Simon. Never thought about it much but man they changed their names a lot back then.

Funny you mention parents, after the death of Jesus his parents don't come up. Or rarely. His father is barely mentioned after the birth story.

no, its like joesph or some guy that starts with a j
