"I am that living bread which has come down from heaven: if anyone eats this bread he shall live for ever. Moreover, the bread which I will give is my own flesh; I give it for the life of the world.....
"In truth, in very truth I tell you, unless you eat the flesh of the Son of Man and drink his blood you can have no life in you. Whoever eats my flesh and drinks my blood possesses everlasting life,and I will raise him up on the last day.....
"Whovever eats my flesh and drinks my blood dwells continually in me and I dwell in him. As the living father sent me, and I live because of the father, so he who eats me shall live because of me.
"This is the bread which came down from heaven; and it is not like the bread which our fathers ate; they are dead, but whoever eats this bread shall live for ever."
John, Chapter 6, verses 53 - 58
