I am in charge of signing up new members at the synagogue I attend. The synagogue is in a transition between rabbis now. We are not getting a new rabbi until September and we don’t even know yet who that new rabbi will be. This past Shabbos, a man we saw for the first time ever starting came to services. He says he wants to join as a member. I talked to him on the phone today and he revealed to me that his mother is a convert to Judaism in the Conservative movement, and he had a bris and bar mitzvah. I don’t know if he is really a Jew or not. Can I accept him as a member?
