Among followers of Judaism, Jesus is viewed as having been the most influential, and consequently the most damaging, of all false messiahs. However, since the traditional Jewish belief is that the messiah has not yet come and the Messianic Age is not yet present, the total rejection of Jesus as either messiah or deity has never been a central issue for Judaism.
Judaism has never accepted any of the claimed fulfillments of prophecy that Christianity attributes to Jesus. Judaism also forbids the worship of a person as a form of idolatry, since the central belief of Judaism is the absolute unity and singularity of God. Jewish eschatology holds that the coming of the Messiah will be associated with a specific series of events that have not yet occurred, including the return of Jews to their homeland and the rebuilding of The Temple, a Messianic Age of peace and understanding during which “the knowledge of God” fills the earth, and since Jews believe that none of these events occurred during the lifetime of Jesus (nor have they occurred afterwards), he is not a candidate for messiah.
Traditional views of Jesus have been mostly negative, although in the Middle Ages Judah Halevi and Maimonides viewed Jesus (like Muhammad) as an important preparatory figure for a future universal ethical monotheism of the Messianic Age. Some modern Jewish thinkers have sympathetically speculated that the historical Jesus may have been closer to Judaism than either the Gospels or traditional Jewish accounts would indicate, starting in the 18th century with the Orthodox Jacob Emden and the reformer Moses Mendelssohn. This view is still espoused by some.
The belief that Jesus is God, the Son of God, or a person of the Trinity, is incompatible with Jewish theology. Jews believe Jesus did not fulfill messianic prophecies that establish the criteria for the coming of the messiah. Authoritative texts of Judaism reject Jesus as God, Divine Being, intermediary between humans and God, messiah or saint. Belief in the Trinity is also held to be incompatible with Judaism, as are a number of other tenets of Christianity.
In Judaism, the idea of God as a duality or trinity is heretical — it is even considered by some polytheistic. According to Judaic beliefs, the Torah rules out a trinitarian God in Deuteronomy (6:4): “Hear Israel, the Lord is our God, the Lord is one.”
Judaism teaches that it is heretical for any man to claim to be God, part of God, or the literal son of God. The Jerusalem Talmud (Ta’anit 2:1) states explicitly: “if a man claims to be God, he is a liar.” Read the full article
