Jesus came from a Jewish family, goes back to King David. He grew as one; but when he began his ministry he saw that many of the things done by that "Religion" were not what God wanted, he than began teaching about where the Kingdom of God is, to love thy neigbour as thy self, do not become hanged on rituals, forgive others, do unto others. All that did not fit well with the Council in Jerusalem, he became a threat in the way they, the Council, kept the people subjected to their will, more than to God's will. Jesus was not about Religion he was about faith, faith in action. Hard to do. It cost him persecution....and the rest is History.
