 In Hasidic Judaism, generally understood as a branch of Orthodox Judaism, there are dynastic spiritual leaders known as "Rebbes", often translated in English as "Grand Rabbi".The office of Rebbe is generally a hereditary one, but may also be passed from Rebbe to student or by recognition of a congregation conferring a sort of coronation to their new Rebbe.Although one does not need to be an ordained Rabbi to be a Rebbe, most Rebbes today are ordained Rabbis.
