I did NOT say that "Christianity equates to cannibalism". I said that Communion is a form of ritual cannibalism.
Baptism is a form of ritual bathing, also.
In Old Tetsament Judaism, you were required to kill a sheep, goat or cow in order to get God to pay attention to you.
God asked Abraham to ritually murder his son, Isaac, and then, just before Abe stuck Isaac with a knife, God told him that it was not necessary, but he still had to murder a sheep that happened to be wandering by.
Jesus did not say a word about the priests requiring the sacrifice of animals in the Temple. He just got upset over the crappy exchange rate between pagan money (which had Caesar's face on it, and therefore was considered impure) and accepted Hebrew money (which was scarce, since it had not been coined for several decades). I suppose that it is some vague feeling that money should not be profane, as Jews considered Roman coins to be, that inspired Americans to mention "In God we Trust" on the coins.
The Crucifixion is seen as a form of blood sacrifice, like ritually killing sheep, goats, chickens and such. No Christians, so far as I know, require anyone to purchase animals and sacrifice them anymore. But the rituals persist. I suppose that this makes them more humane, but no less silly, if you consider it from a logical point of view.
