Judaism
There are some movements that combine elements of Judaism with those of other religions. The most well-known of these is Messianic Judaism, a religious movement, which arose in the 1960s, that incorporates elements of Judaism with the tenets of Christianity. The movement generally states that Jesus is the Jewish Messiah, that he is one of the Three Divine Persons, and that salvation is only achieved through acceptance of Jesus as one's savior. Some members of the movement argue that Messianic Judaism is a sect of Judaism. Jewish organizations of every denomination reject this, stating that Messianic Judaism is a Christian sect, because it teaches creeds which are identical to those of Pauline Christianity.
Origins of Rabbinic Judaism
Although the Rabbis traced their origins to the Pharisees, Rabbinic Judaism nevertheless involved a radical repudiation of certain elements of Pharisaism—elements that were basic to Second Temple Judaism. The Pharisees had been partisan. Members of different sects argued with one another over the correctness of their respective interpretations, see also Hillel and Shammai. After the destruction of the Second Temple, these sectarian divisions ended. The term "Pharisee" was no longer used, perhaps because it was a term more often used by non-Pharisees, but also because the term was explicitly sectarian. The Rabbis claimed leadership over all Jews, and added to the Amidah the "birkat haMinim" (see Council of Jamnia), a prayer which in part exclaims, "Praised are You O Lord, who breaks enemies and defeats the arrogant," and which is understood as a rejection of sectarians and sectarianism. This shift by no means resolved conflicts over the interpretation of the Torah; rather, it relocated debates between sects to debates within Rabbinic Judaism.
