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.
Orthodox Judaism
Orthodox Judaism may be categorized according to varying criteria. The most recognizable sub-group are the "Haredim" (literally, "anxious" or "fervent"), also known as Ultra-Orthodox, strictly Orthodox and the like. They form the conservative, strict and self-segregating part of the Orthodox spectrum. "Haredim" are characterized by a minimal engagement with modern society and culture if not their wholesale rejection, by avowed precedence given to religious values, and by a high degree of rabbinic authority and involvement in daily life. In spite of many differences, "Haredi" rabbis and communities generally recognize each other as such, and therefore accord respect and legitimacy between them. They also hold a lukewarm or negative assessment of more modernist Orthodox groups. "Haredim" are easily discerned by their mode of dress, often all black for men and modest by religious standards for women (including hair covering, long skirts, etc.)
