I’ve never come across Sethian Gnosticism until just now. It was apparently an early non-Christian form of gnosticism which viewed the Biblical figure of Seth as a savior figure, rather than Jesus. More on that as I find it…

Also, this is just tagging along, not so much cause it’s related, but because I found it independently around the same time. It’s a thing about the famous psychic Edgar Cayce’s readings about Jesus and his past lives as different figures in the Bible and apocryphal tradition.
