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.
Religious denomination
The movements differ in their views on various issues. These issues include the level of observance, the methodology for interpreting and understanding Jewish law, biblical authorship, textual criticism, and the nature or role of the messiah (or messianic age). Across these movements there are marked differences in liturgy, especially in the language in which services are conducted, with the more traditional movements emphasizing Hebrew. The sharpest theological division occurs between Orthodox and non-Orthodox Jews who adhere to other denominations, such that the non-Orthodox movements are sometimes referred to collectively as the "liberal denominations" or "progressive streams."
