Does the Beta Israel community have Kohens? Are Kahens equivalent? If so, are they descended from Aaron?
The following website writes as follows:
Although the Beta Israel — the Ethiopian Jews, a minority of today’s Israeli population, who mostly came to the country in two waves in the 1980s and early 1990s—maintain the priesthood tradition, they are unique in that they do not consider it to be hereditary. Instead, the Beta Israel priest, called as Kes or Kahin (Cohen), is elected by his community. Traditionally, Keses, as Ken Blady explains, “were for the most part drawn from the general population, and each was selected based on his own merits” (p. 363).
So it would seem that unlike the Kohanim as we know it, which one is born into, their equivalent is something that is an appointed title.
