Gnosticism is essentially the belief that the universe was created by an imperfect deity, known as the Demiurge, and that a Supreme Being of pure good exists indepently of said Demiurge. The Demiurge is usually thought of to be either malevolent or simply unable to properly execute perfect good. It's easy enough to see the God of the Hebrews as a Demiurge. After all, his track record is far from perfect. In the delightfully amusing language of Richard Dawkins:
"The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully."
But this raises the question: if He's the Demiurge, who's the Supreme Being? Who's the Force of pure, omnipotent good that will save us from this world of suffering?
The answer struck me this suddenly afternoon, as I sat in bemused debate with a small troupe of Lubavitchers who were attempting to persuade me to don tefillin. It was so blindingly obvious, that I am astonished I didn't figure it out sooner. The Supreme Being is this guy:

Ha. Bet you didn't think you'd see a photo of him on my blog. Or should that be a capitalised "Him"? After all, according to Lubavitch thought, that man is the Messiah. The one who will lead us into an era of pure good, and perfect/supplant the evil-ridden universe of the Hebrew God.
Sounds like gnosticism to me. What do you think?
