Christianity as we have come to know it emerged from Judaism in the first century of the Common Era. The first Christians were Jews, and likely subscribed to Jewish beliefs and practices common at the time. Among these was a belief that a messiah—a descendant of King David—would restore the monarchy and Jewish independence.
According to mainstream Jewish beliefs, the failure of Jesus to restore the Kingdom, and his crucifixion by Romans, negated claims that he was the messiah (since most Jews do not accept that Jesus was the messiah, they reject the use of the full (Christian) name. See the Jewish conception of the messiah for a more detailed discussion of the Jewish understanding of the messiah).
Nevertheless, many of Jesus's followers—perhaps inspired by encounters with Jesus after his crucifixion and entombment, but also drawing on alternative interpretations of Biblical passages—redefined the concept of messiah to encompass the resurrection and the promise of a second coming. In addition to this alternative understanding of the messiah, early Christians brought from Judaism its scriptures, fundamental doctrines such as monotheism, and other beliefs and practices.
Judaism teaches that it is heretical for any man to claim to be a part of god; Jews view Jesus as just one in a long list of Jewish claimants to be the messiah. The article on the concept of the messiah contains a list of many people who claimed to be the messiah, son of God, or both.
The predominant Jewish understanding of moschiach ("the messiah") is based on the writings of Rabbi Moshe ben Maimon, better known as Maimonides, or the Rambam. His views on the messiah are discussed in his Mishneh Torah, his 14 volume compendium of Jewish law, in the section Hilkhot Melakhim Umilchamoteihem, chapter 11. Maimonides writes:
Most Orthodox Jews hold that Jews are obligated to accept Maimonides's 13 Principles of Faith; most have an unwavering belief in the coming of the messiah. Hasidic Jews also claim to adhere to Maimonides's writings, but an analysis of Hasidic writings show that although they agree with Maimonides that there will be a human messiah, Hasidic views of the messiah often posit that he will perform supernatural miracles.
Emet Ve-Emunah, the Conservative movement's statement of principles, states:
Reform Judaism and Reconstructionist Judaism generally do not accept the idea that there will be a messiah. Some believe that there may be a messianic age, which all Jews are obligated to work towards.
Reform Rabbis Rifat Sonsino and Daniel B. Syme wrote "What Happens After I Die? Jewish Views of Life After Death" (UAHC Press), which offers a wide spectrum of Jewish responses to the question of life after death, from traditional to Reform.
In 1976, the Central Conference of American Rabbis, the official body of American Reform rabbis, authored "Reform Judaism: A Centenary Perspective". While not an official statement of principles, it is meant to describe the spiritual state of modern Reform Judaism. In regards to the messianic era, it states:
Historical background
Jewish theology
The view of Maimonides
Maimonides next writes why Jews believe that Jesus was wrong to create Christianity (and why they believe that Mohammed was wrong to create Islam;) he laments the pains that Jews felt as a result of these new faiths that attempted to surplant Judaism. However, Maimonides then goes on to say that both faiths help God redeem the world.
But if he did not succeed until now, or if he was killed, it becomes known that he is not this one of whom the Torah had promised us, and he is indeed like all proper and wholesome kings of the House of David who died. The Holy One, Blessed Be He, only set him up to try the public by him, thus: "And from the seekers of wisdom there shall stumble, to purify among them and to clarify and to brighten until the time of the ending, for there is yet to the set time" (Daniel 11:35).The messiah in Orthodox Judaism
