§ 134. Other Gnostic Sects.
Schaff notes that several of the Christian fathers make mention of different Gnostic groups. He describes three with brief details. The Docetists said that Christ did not have a real body. Therefore he couldn’t actually suffer and die (Schaff 2014, Loc. 18602). The Antitactes were a group of Gnostics who were radically licentious. They did not follow one particular founder. Thirdly, the Prodicians considered themselves above all the law, a special royal order (Schaff 2014, Loc. 18608). The points of similarity among many of the Gnostics is a rejection of the law and of the biblical view of one God as the creator and sustainer of all.
