All three the main branches of the Abrahamic religions have subsequently adopted the concept of messianism, but there are vast differences between these beliefs:
Judaism says that the messiah is still to come, but that he will be a great charismatic human leader, not a god. They say that Jesus was not the messiah, because he did not complete the several tasks set out for him in the Old Testament. They consider Jesus as a mere mortal preacher with a following, who got into trouble with the authorities and who later got embellished with stories about a virgin birth, miracles and a resurrection.
Islam believes that Jesus was the messiah as prophesied in the Old Testament and that he did many miracles, but that he was a human prophet and not the son of God.
Christianity is the only of the three main streams that believe in the divine nature of Jesus. Some of them say that he is the son of God, part of the Holy Trinity (a concept invented by the Catholics between 200 and 300 years after the death of Jesus). Some reject the concept of the Trinity and say that he is the son of God, but not God himself (for example the Mormons) or that he was the archangel Michael (Jehovah's Witnesses).
