The Rabbinate and Rabbi Amar do not recognize overseas conversion and gets. I don't know who are these 50 rabbis that have been approved by Amar but I know for sure that Amar has no authority to rule over the world Orthodox Jewry. Amar does undermine the authority of non - Israeli orthodoxy and doesn't recognize its status. As it has been said, the world already has a Pope. We don't need another one. I really don't understand the meaning of all these anti-Diasporic attitudes of Amar. By doing so he only augments the authoritarian more than authoritative role of the Israeli rabbinate.
