The "not controlling Jesus", yes, I can see that you'd rather think Jesus was *there*, though perhaps Bad People do consume his flesh but he doesn't choose to save them.

But, it only pushes it back as far as the person officiating the ceremony, doesn't it? Does Jesus always answer prayers for turning bread and wine into Him? Does it matter whom from, or if they're Bad? Can a bad priest give communion? Turn bread into Jesus and defile it?
