But, Jesus did NOT start Christianity. He taught the Law of Moses and he opened the way for anyone to study the Law of Moses. Not 1 jot or tittle shall fall from the Law until ALL is done.
Christianity is lawlessness to God wrapped up in a Jesus as an idol person. Nowhere did Jesus teach to do the things any Christian does.
Yes, you understand Judaism vs. The Law of Moses. But Jesus and the OT Law were inclusive of all people. Look up:
Numbers 9:14, Lev 17:10, for example to see the Laws are for all people.
