[I've heard this argument several times from Protestants before, and it just doesn't set right with me. Primarily, this is because the differences are *not* trivial. The nature of the Eucharist (Real Presence vs. Sorta real presence vs. just a symbol), how is Salvation received (works/faith vs. faith alone vs. works alone), and whether man has free will are just three non-trivial disputes between the Christian faiths.]
Not trivial at all. Did you know that drinking blood is forbidden of God? You would be rejected of God because you drink blood, cannibalism is a result of mystical misintrepretation of scripture , the body and blood of Jesus was given at the cross and went into the ground and was not drank at all. Satanists drink blood, sacrifice humans and animals, and do these evil things..
Funny, "cannibalism" was exactly the complaint levied against the early Christians -- ca. AD 150 -- by the Roman pagans. Some things never change.
