John 6:51-58 (Douay-Rheims 1899 American Edition.)
51I am the living bread which came down from heaven.
52If 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.
53The Jews therefore strove among themselves, saying: How can this man give us his flesh to eat?
54Then Jesus said to them: Amen, 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.
55He that eateth my flesh, and drinketh my blood, hath everlasting life: and I will raise him up in the last day.
56For my flesh is meat indeed: and my blood is drink indeed.
57He that eateth my flesh, and drinketh my blood, abideth in me, and I in him.
58As the living Father hath sent me, and I live by the Father; so he that eateth me, the same also shall live by me.
