So, if we do it, it's ok...but if you do it, because your religious mubojumbo is outside the Greco-Roman-Jewish tradition

Well, then you're fucked and you're going to hell! Ratzinger's hits just keep on coming.  His priest says a prayer, and God gives you a baby, or transubstantiates some  stale wonderbread and left over Chablis into cannibalism, or cures your sore throat by slapping some candles against your neck or...or...there's just such a wealth of magikal nonsense in Christianity, and particularly Catholicism that I'm overwhelmed. But, if your priest-figure makes an image of you and blows on it to help you breathe, well, that's just not going to work and is a sin. Got it...
