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.
Pharisees
During the Second Temple era, when Jews were divided into sects, the Pharisees were one sect among many, and partisan. Each sect claimed a monopoly on the truth, and discouraged marriage between members of different sects. Members of different sects did, however, argue with one another over the correctness of their respective interpretations, although there is no significant, reliable record of such debates between sects. After the destruction of the Second Temple, these sectarian divisions ended. The Rabbis avoided the term "Pharisee," perhaps because it was a term more often used by non-Pharisees, but also because the term was explicitly sectarian. The Rabbis claimed leadership over all Jews, and added to the Amidah the "birkat haMinim", a prayer which in part exclaims, "Praised are You O Lord, who breaks enemies and defeats the wicked," and which is understood as a rejection of sectarians and sectarianism. This shift by no means resolved conflicts over the interpretation of the Torah; rather, it relocated debates between sects to debates within Rabbinic Judaism. The Pharisaic commitment to scholarly debate as a value in and of itself, rather than merely a byproduct of sectarianism, emerged as a defining feature of Rabbinic Judaism.
