"I am the living bread which came down from heaven. If any man eat of this bread, he shall live for ever; and the bread that I will give, is my flesh, for the life of the world." The Jews therefore strove among themselves, saying:
"How can this man give us his flesh to eat?"
Then Jesus said to them:
amen I say unto you: Except you eat the flesh of the Son of man, and
drink his blood, you shall not have life in you. He that eateth my
flesh, and drinketh my blood, hath everlasting life: and I will raise
him up in the last day." (Jn 6.51-55)
