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.
Reform Judaism
The various regional branches sharing these beliefs, including the American Union for Reform Judaism (URJ), the Movement for Reform Judaism (MRJ) and Liberal Judaism in Britain, and the Israel Movement for Reform and Progressive Judaism, are all united within the international World Union for Progressive Judaism. Founded in 1926, the WUPJ estimates it represents at least 1.8 million people in 50 countries: close to a million registered adult congregants as well as numerous unaffiliated individuals who identify with it.
