From Idolatry to Conversion: Judaism and Non-Jews: Conversion: Leadership by Converts:
Can a convert to Judaism be an official in a Jewish organization?
The Talmud (Yevamos 45b, Kiddushin 76b), commenting on Deut. 17:15,
says that any position of authority can be held only by a person of
Jewish descent. But a learned convert can hold a Rabbinical position;
indeed, some of the heads of the Sanhedrin were proselytes.
