Its adherents, the Mandaeans, revere Adam, Abel, Seth, Enos, Noah, Shem, Aram, and especially John the Baptist. Mandaeans consider Adam, Seth, Noah, Shem, and John the Baptist to be prophets, with Adam being the founder of the religion and John being the greatest and final prophet.

The Elcesaites, Elkasaites, Elkesaites or Elchasaites were an ancient Jewish Christian sect in Lower Mesopotamia, then the province of Asoristan in the Sasanian Empire that was active between the early second century and the fifth century CE. The members of this sect, which originated in the Transjordan, performed frequent baptisms for purification and had a Gnostic orientation.
