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.
Jews
After the destruction of the Second Temple, Judaism lost much of its sectarian nature. Nevertheless, a significant Hellenized Diaspora remained, centered in Alexandria, at the time the largest urban Jewish community in the world. Hellenism was a force not just in the Diaspora but also in the Land of Israel over a long period of time. Generally, scholars view Rabbinic Judaism as having been meaningfully influenced by Hellenism.
