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.
Pharisees
During the Second Temple era, when Jews were divided into sects, the Pharisees were one sect among many, and partisan. Each sect claimed a monopoly on the truth, and discouraged marriage between members of different sects. Members of different sects did, however, argue with one another over the correctness of their respective interpretations, although there is no significant, reliable record of such debates between sects. After the destruction of the Second Temple, these sectarian divisions ended. The Rabbis avoided the term "Pharisee," 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", a prayer which in part exclaims, "Praised are You O Lord, who breaks enemies and defeats the wicked," 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. The Pharisaic commitment to scholarly debate as a value in and of itself, rather than merely a byproduct of sectarianism, emerged as a defining feature of Rabbinic Judaism.
