John 6:25-71 (Revised Standard Version)

25When they found him on the other side of the sea, they said to him, "Rabbi, when did you come here?" Jesus answered them, "Truly, truly, I say to you, you seek me, not becasue you saw signs, but because you ate your fill of the loaves (see same chapter, verses 5-14, multiplication of the kid's loaves and fishes). Do not labor for the food which perishes, but for the food which endures to eternal life, which the Son of man will give to you (which Jesus will make clear before this quotation is over); for on him has God the Father set his seal (in the baptism in the Jordan with John?)." Then they said to him, "What must we do, to be doing the works of God?" Jesus answered them, "This is the work of God, that you believe in him whom he has sent." So they said to him, "Then what sign do you do, that we may see, and believe in you? What work do you perform? Our fathers ate manna in the wilderness; as it is written, 'He gave them bread from heaven to eat.'"

35Jesus then said to them, "Truly, truly I say to you, it was not Moses who gave you the bread from heaven; my Father gives you the true bread that comes down from heaven. For the bread of God is that which comes down from heaven, and gives life to the world." They said to him, "Lord, give us this bread always." Jesus said to them, "I am the bread of life; he who comes to me shall not hunger, and he who believes inme shall never thirst. But I said to you that you have seen me yet do not believe. All that the Father gives me will come to me; and him who comes to me I will not cast out. For I have come down from heaven, not to do my own will, but the will of him who sent me; and this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up at the last day. For this is the will of my Father, that everyone who sees the son and believes in him should have eternal life; and I will raise him up on the last day."

41The Jews then murmured at him, because he said, "I am the bread which came down from heaven." They said, "Is not this Jesus, the son of Joseph, whose father and mother we know? How does he now say, 'I have come down from heaven'?' Jesus answered them, "Do not murmur among yourselves. No one can come to me unless the father who sent me draws him; and I will raise him up on the last day. It is written in the prophests, 'And they shall be taught by God.' Every one who has heard and learned from the Father comes to me. Not that anyone has seen the Father except him who is from God; he has seen the Father. Truly, truly, I say to you, he who believes has eternal life. I am the bread of life. Yours fathers ate manna in the wilderness, and they died. This is the bread which comes down from heaven, that a man may eat of it and not die. I am the living bread which came down from heaven; if any one eats of this bread, he will live forever; and the bread which I shall give for the life of the world is my flesh." (This is fairly straightforward in its tone and approach, i.e. 'my flesh')

52The Jews then disputed among themselves, saying, "How can this man give us his flesh to eat?" (This question shows Jesus hearers think he means to give them his literal flesh to eat in some way) 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 (the Jews considered the blood to contain the life and so it was strictly taboo to drink blood); 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 becasue 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 forever." (Is he kidding? Was he serious? I have to assume so because he was a Rabbi or Teacher of Israel who was performing a part of his actual ministry as such.) This he said in the synagogue, as he taught at Capernaum.

60 Many of his disciples, when they heard it, said, "This is a hard saying; who can listen to it?" (A greater number of his large gathering of disciples could hardly heard this, much less the other teachers) But Jesus, knowing in himself that his disciples murmured at it, said to them, "Do you take offense at this? Then what if you were to see the Son of man ascending where he was before? It is the spirit that give life, the flesh is of no avail; the words that I have spoken to you are spirit and life. (He obviously believes what he is saying so firmly as truth he calls what he has said spirit and life, in other words, to eat his flesh and drink his blood are spirit and life) But there are some of you that do not believe." For Jesus knew from the first who those were that did not believe, and who it was that should betray him. And he said, "This is why I told you that no one can come to me unless it is granted him by the Father."

66After this many of his disciples drew back and no longer went about with him. Jesus said to the twelve, "Will you also go away?" Simon Peter answered him, "Lord, to whom shall we go? You have the words of eternal life (to eat his body and drink his blood, amongst many other sayings, such as A new commandment I give to you, that you love one another); and we have believed, and have come to know that you are the holy one of God (this clearly shows Peter as the leader of the twelve, in speaking for all the members of the group without knowing Jesus further revelation, but one of you is a devil)." Jesus answered them, "Did I not choose you, the twelve, and one of you is a devil?" He spoke of Judas then son of Simon Iscariot, for he, one of the twelve, was to betray him.
