Black Judaism
Black Judaism is the collective term used to describe sects of Judaism predominantly practiced by the members of the African communities, both within the African Continent and outside Africa (such as North America). It is theologically characterized by the selective acceptance of the Judaic faith (in some cases such selective acceptance has historical circumstances), and that the belief system of Black Judaism is significantly different from the mainstream sects of Judaism. In addition, although Black Judaic communities adopt Judaic practices such as Jewish holidays and Jewish prayers, they are generally not recognized by the mainstream Jewish societies as legitimately Jewish.
Nazarene judaism (religious movement)
The Nazarenes (in hebrew: נַצְרָתִים) (transliteration: "Natzratim") or Nazarene Judaism are followers of Jesus of Nazareth (Yeshua) and practice a monotheistic religion. The Nazarenes are part of the Jewish people, but they are not part of Orthodox Judaism. The Nazarenes have some ideological differences with Messianic Jews.
