Yeah I saw your post today about the Talmud. It seemed like it fit quite well with what early protestants said - that the Pope is "the" Antichrist (Quotes because I'm not sure if a definite article is theologically sensible). I've had a hypothesis, which I can't verify because I don't know enough, that Islam was really an outgrowth of iconoclasm. It seems like it sprang into being at a time when the church was having that fight. Their destruction of any human image in art seems like a reaction to idolatry, whether the supposed idolatry is in Christianity or other religions. And that Orthodox thing with the desert fathers - the only desert around is where Islam started.
