I know the standard history is that gnostic christianities came in strong about the 2nd century. So the present protestant, orthodox, and catholic churches harp on that to discredit it.
I find some aspects of gnosticism very appealling though. I also think there's a strong case for early forms having roots going right back to around the time of Paul,
But it looks like this copy of the Gospel of Judas, fits the description of a version used by the Cainites. So unlike, say, the Gospel of Thomas, I don't really think this gospel holds any genuine early traditions. It might also not be properly interpreted so I'm waiting for the alternative.
Besides my general interest in variant forms of christianity, I also luv this gosple for a very unintellectual reason. Its gotten the local dub CO and elders, as well as some local fundies I've come across riled up and its fun to discuss it with them.
