myelanie, designs is correct on that that Messiah in Judaism is not represented by Jesus. Jesus was not Mesiah, because he did not fullfill any prophecies what would be expected from king of peace. Judaism does not teach salvation through another person, nobody can redeem your sin. It is only yours own responsiblity to have a good standing with G-d. Salvation is achieved through obedience to Torah, love of G-D, and work on yourself to achieve it. No shortcut on someone else back. Did Jesus in his time fullfill any of these: Became a king of Israel, returned Jewish people to Isreal (in time where majority lived outside Judea), rebuild temple in Jerusalem, bring peace to the world? Jesus was anointed by woman, not by prophet as did Samuel in the past. Jesus was false prophet, and he died and he is not comming back.
Paul deliberately created split between Judaism and Christianity by his own will by invalidating Torah and making G-d given commands obsolote. He knew he would face a justice in Jerusalem for it and rather run under protection of Nero than defend his truth in the jury of his fellow Jews.
