John 6: 51-58 I am the living bread which came down from heaven; if any one eats of this bread, he will live for ever; and the bread which I shall give for the life of the world is my flesh.”  The Jews then disputed among themselves, saying, “How can this man give us his flesh to eat?”  So Jesus said to them, “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.  He who eats my flesh and drinks my blood abides in me, and I in him.  As the living Father sent me, and I live because of the Father, so he who eats me will live because of me.  This is the bread which came down from heaven, not such as the fathers ate and died; he who eats this bread will live for ever.”
John 17: 11, 20-23 And now I am no more in the world, but they are in the world, and I am coming to thee. Holy Father, keep them in thy name, which thou hast given me, that they may be one, even as we are one.  “I do not pray for these only, but also for those who believe in me through their word,  that they may all be one; even as thou, Father, art in me, and I in thee, that they also may be in us, so that the world may believe that thou hast sent me.  The glory which thou hast given me I have given to them, that they may be one even as we are one,  I in them and thou in me, that they may become perfectly one, so that the world may know that thou hast sent me and hast loved them even as thou hast loved me.
