Mandaeism
There are three grades of priesthood in Mandaeism: the tarmidia "disciples" (Neo-Mandaic tarmidānā), the ganzibria "treasurers" (from Old Persian ganza-bara "id.", Neo-Mandaic ) and the rišamma "leader of the people."  This last office, the highest level of the Mandaean priesthood, has lain vacant for many years.  At the moment, the highest office currently occupied is that of the , a title which appears first in a religious context in the Aramaic ritual texts from Persepolis (ca. 3rd c. BCE) and which may be related to the kamnaskires (Elamite <qa-ap-nu-iš-ki-ra> kapnuskir "treasurer"), title of the rulers of Elymais (modern Khuzestan) during the Hellenistic age. Traditionally, any  who baptizes seven or more  may qualify for the office of rišamma, though the Mandaean community has yet to rally as a whole behind any single candidate.
