Jesus only said that the law would not pass away until it was fulfilled which he believed he did upon dying. So the law is irrelevant now according to Jesus.
Jesus said no such thing. He was a religious Jew 100% and so were his early followers. Christianity was a Jewish sect/cult.
Jesus told his followers to keep the Law, the idea that it passed away on the cross is a Paulene invention.
Jesus broke up families and enticed gullible men like Peter to abandon their wives, children and businesses to follow him around Palestine preaching false apocalyptic prophecies.
