I have to say that it is just baffling that many honest Christians - avowed, self-proclaimed fundamentalists - simply will not believe what it says, right there, in the Bible.
"Truly, truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you; he who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. For my flesh is food indeed, and my blood is drink indeed (John 6:48-51; 52-55, RSV)
What can this mean? There is only one explanation. It is incredible - as incredible and as stunning as the Incarnation. But it is true. The Eucharist is God Himself, who gives Himself to us as food.
We adore you oh Christ and we praise You; because by Your holy cross You have redeemed the world.
It was unheard of in Judaism to eat flesh and drink human blood. It is nowhere to be found in Jewish religious tradition as acceptable sacrifice.
And Jesus being a Jew who obeyed the Law perfectly would not have done something the Law explicitly fobids! So, something is not kosher here, no pun intended.
Therefore, the idea is either spiritually symbolic or it is cultist cannibalism. It cannot be both. God offeirng himself as real food and real drink...so that by consuming him we are consumed by him. Good Lord!
