Grant Adamson is now speaking about Sethian counter culture in the Secret Book of John.
Interesting that polemics in the book from the Pharisee might have been a Sethian opposition group (s).
John represent new Sethian converts who accept that the Jewish/Christian scriptures are crap.
But all these Sethians agreed that Moses was listening to the wrong deity. And this deity, Saklas or Yaldabaoth, has to be parodied as much as possible, as seen by the Gnostic texts.
