True. So late he isn’t really in the Real Bible ™ - the OT. The snake was not Satan, and my Hebrew School teachers and the prayers I said never mention him. I’d say purely a Christian invention (I’ve read Pagels’ book a long time ago) but it is possible a satan-like character was a part of the sects back at the turn of the Common Era.
I never did have much respect for the “Everybody is right, nobody is wrong and everybody gets their own reality!” argument.
