Jesus wanted the Mosaic Law upheld in all its details. “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven.” (Matthew 5: 17-19)
Symptomatic of this is Jesus’ hair, always shown long in keeping with Leviticus 19:27 “Do not cut the hair at the sides of your head or clip off the edges of your beard.”
To Jesus, the Romans were pig-eating, uncircumcised, beard-shaving idolators who needed to be expelled from Israel.
But Paul wanted to move away from ethnic-based Judaism to a universal religion acceptable to the whole Roman Empire. Paul’s entire outlook is Roman. He writes: “Does not the very nature of things teach you that if a man has long hair, it is a disgrace to him” (1 Corinthians 11: 14)
Paul’s Christianity is hostile to the beliefs of Jesus. The hair says it all.
