priesthood can trace its immediate origins to the first half of the 19th century. In 1831, an outbreak of cholera in Shushtar, Iran devastated the region and eliminated most, if not all, of the Mandaean religious authorities there. Two of the surviving acolytes (šgandia), Yahia Bihram and Ram Zihrun, reestablished the priesthood in Suq al-Shuyukh on the basis of their own training and the texts that were available to them. In 2009, there were two dozen Mandaean priests in the world. However, according to the Mandaean Society in America, the number of priests has been growing in recent years. Scholarship According to Edmondo Lupieri, as stated in his article in Encyclopædia Iranica, "The possible historical connection with John the Baptist, as seen in the newly translated Mandaean texts, convinced many (notably R. Bultmann) that it was possible, through the Mandaean traditions, to shed some new light on the history of John and on the origins of Christianity. This brought around a revival of the otherwise almost fully abandoned idea of their Palestinian origins. As the archeological discovery of Mandaean incantation bowls and lead amulets proved a pre-Islamic Mandaean presence in the southern Mesopotamia, scholars were obliged to hypothesize otherwise unknown persecutions by Jews or by Christians to explain the reason for Mandaeans' departure from Palestine." Lupieri believes Mandaeism is a post-Christian southern Mesopotamian Gnostic off-shoot and claims that Zazai d-Gawazta to be the founder of Mandaeism in the 2nd Century. Jorunn J. Buckley refutes this by confirming scribes that predate Zazai who copied the Ginza Rabba. In addition to Edmondo Lupieri, Christa Müller-Kessler argues against the Palestinian origin theory of the Mandaeans claiming that the Mandaeans are Mesopotamian. Edwin Yamauchi believes Mandaeism's origin lies in the Transjordan, where a group of 'non-Jews' migrated to Mesopotamia and combined their Gnostic beliefs with indigenous Mesopotamian beliefs at the end of the 2nd century CE. Kevin van Bladel claims that Mandaeism originated no earlier than 5th century Sassanid Mesopotamia, a thesis which has been criticized by James F. McGrath. Brikha Nasoraia, a Mandaean priest and scholar, accepts a two-origin theory in which he considers the contemporary Mandaeans to have descended from both a line of Mandaeans who had originated from the Jordan valley of Palestine, as well as another group of Mandaeans (or Gnostics) who were indigenous to southern Mesopotamia. Thus, the historical merging of the two groups gave rise to the Mandaeans
