Are you a teenager?
there are people who believe that since a priest mumbles some words over a cracker and a sip of wine they actually become the flesh and blood of a dead man. If they believe thats what theyre consuming, its cannibalism.
Catholic, Orthodox, Lutheran, nor Anglican churches believe they are consuming the flesh and blood of a dead man. So, no it is not cannibalism.
Eating another human being, even symbolically, is beyond mere weird to me. I have no problem if you want to do it. As long as you’re not forcing me to to either do it or pay for it, I don’t really care what you do with your Sunday mornings.
