deconversion

I am reading Karen Armstrong's "A Case for God" right now and she said something very interesting. "They [stoics] saw the whole of reality as animated by a fiery vaporous breath that Zeno called Logos ("Reason"), Pneuma ("Spirit"), and God." When I read that, the first thoughts that crossed my mind were "Gospel of John" and "Trinity." I already knew that ideas like incarnation and the death/resurrection of God's was not originally a Christian concept. Is that true for the Trinity as well? Does anybody here know much about the stoics and can you recommend any good books about them?

I don't know about that, but there is a Jewish Kabbalistic teaching referred to as The Three Pillars which some believe was the foundation for Christianity's trinity.

Since the very first Christians were Jews who lived in a Greek culture and later gentiles came into the fold, it is very possible that they synthesized both the kabbalistic and the stoic ideas of the godhead.
