the refutiation of judaism their false commandments, hereditary idolatry et al is what jesus taught the original religion of antiquity - it is c-bear who believes the forgeries and fallacies of the desert religions than what were the true 1st century events and path taken by jesus.
Matthew 5:17-18
17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Jesus didn't come to refute Judaism but to fulfill the law of Moses. What I think you do not understand nor do the Jews is that Jesus was the one who gave to Moses the law of Moses. At the time of Moses the children of Israel were a hard hearted people that could not endure the higher law of the gospel. It wasn't until the the days of Jesus that the law was to be fulfilled and the higher fulfilled law was to come. Jesus is the Great I AM. It was he who gave Moses the lesser law.
John 8:56-59
56 Your father Abraham rejoiced to see my day: and he saw it, and was glad.
57 Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham?
58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was,
I am.
59 Then took they up stones to cast at him: but Jesus hid himself, and went out of the temple, going through the midst of them, and so passed by.
When Jesus told them that "Before Abraham was, I AM" he meant that he was the Great I Am (see Exodus 3:14). For this reason the Jews took up stones to cast at him because they considered it blasphemy that Jesus consider himself the Great I Am. But he was. It was He who gave them their law unto Moses. This is why he was not there to do way or destroy the law but to fulfill the law with the law of the gospel.
