Okay, so Jesus came, sent his Apostles, Gospel is spread throughout the Old World,
suddenly these Gnostic groups pop up mysteriously, but where did they come from?
There were and are various groups like the Archontics, Bardaisanites, Basilideans, Sethians, Thomasenes, Valentinians, Borborites, Cainites,
Carpocratians, Marcosians, Ophites, Bogomilism, Catharism, Paulicianism, Manichaeism, Mandaeanism (the last true ancient Gnostics who
survive to this very day).
Most of them contain similar mythologies, such as the Great Evil Demiurge (craftsman
god), the Fallen Sophia (and various other Divine emanations called “Aeons”), and very
extensive cosmologies, which makes it hard for me to suppose that it all came out of a
void or from the personal insights of individuals.
We can understand how Marcionism came up, when Marcion of Sinope at Rome was
unable to reconcile the Old and New Testament therefore came to the false conclusion
that the God of the Old Testament was some evil force and that Jesus was the only true
God, etc etc etc…
But how did all the other crazy Gnostic cults come to be?
