First of all, if you are being serious, then I find it a little offensive: saying that the Holy Communion is cannibalism and an idiotic and disgusting image. That insult has been thrown at the Church for hundreds of years.
Well, what would have happened if everyone in first century Judea ate Christ’s Flesh? For one, He wouldn’t have been crucified, He wouldn’t have died for our sins, and His Resurrection for our salvation would be nonexistant.
I seem to think that any Christian would of thought cannibalizing Christ would have made the Christian movement utterly false, and, ultimately, an idiotic religion. - since their Messiah was consumed by many people.
