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.
African-American culture
There are 150,000 African Americans in the United States who practice Judaism. Some of these are members of mainstream Jewish groups like the Reform, Conservative, or Orthodox branches of Judaism; others belong to non-mainstream Jewish groups like the Black Hebrew Israelites. The Black Hebrew Israelites are a collection of African-American religious organizations whose practices and beliefs are derived to some extent from Judaism. Their varied teachings often include, that African Americans are descended from the Biblical Israelites.
