a sect of the Ophites (q.v.), of the 2d century, who paid divine honor to Seth, believing him to have reappeared in the person of Jesus Christ. They taught that Seth was made by a third divinity, and substituted in the room of the two families of Abel and Cain, destroyed by the deluge. They were thus distinguished from the Cainites (q.v.), who assigned the highest place to Cain. The Sethians regarded Cain as a representative of the Hylic, Abel of the Psychical, and Seth, who was finally to reappear in the person of the Messiah, of the Pneumatic principle.
