Heh, the Catholic church uses real wine! Real cheap wine. Don't want the parishioners running into each other in the parking lot after all do we? lol. Why do we use wine? Because Jesus didn't turn water into grape juice, lol. Oh well. MCH
I don't see it as ritual "cannibalism". It is a way of representing Christ's actual presence at the Eucharist. Take my body and blood. Take all that I am. At the last supper Jesus didn't cut prices of himself off for the others to eat. Ewww.
As for the turning water into wine? That was the only way I could fit grape juice in and it be funny. Honestly girl, I'm beginning to worry about you. You seem wound so tight you could all a sudden snap and start spinnin' in circles. Then you'd be like a whirling dervish, lol.
