Jesus did not, IMO, found christianity AT ALL---full pictureWell just so you know my starting point. I am not going to attempt to convince you that since Jesus was Jewish, it means XYZ for you or whatever. In other words you can consider this (what I hope) a rational conversation between two posters. Nothing personal, no ulterior motives.
So that said.
Jesus was a devout Jew. In fact He was the perfect Jew, you might say. He fulfilled the law. So there's no way to deny that He taught primarily Jewish values and lessons--that was God's plan. But of course that's not the full picture either. If it was the full picture I guess there would be no Christians.
