Yeah that's a strange line of reasoning. But then the Catholic Church also has only the priest drinking the cup whereas all ceremonial juice/wine in the Bible (Old and New Testaments) was shared around to everyone participating. The New Testament indicates a complete movement away from forbidden foods, especially in the books of Acts, Romans, and James. It's one of those topics that just about every author of the New Testament mentioned rather than the various "Pauline" or "Johannine" or other systemics. So, sorry I'm not sure what you're referring to?
