41 Then the Jews who were hostile to Jesus began complaining about him because he said, “I am the bread that came down from heaven,” 42 and they said, “Isn’t this Jesus the son of Joseph, whose father and mother we know? How can he now say, ‘I have come down from heaven’?” 43 Jesus replied, “Do not complain about me to one another. 44 No one can come to me unless the Father who sent me draws him, and I will raise him up at the last day. 45 It is written in the prophets, ‘And they will all be taught by God.’ Everyone who hears and learns from the Father comes to me. 46 (Not that anyone has seen the Father except the one who is from God—he has seen the Father.) 47 I tell you the solemn truth, the one who believes has eternal life. 48 I am the bread of life. 49 Your ancestors ate the manna in the wilderness, and they died. 50 This is the bread that has come down from heaven, so that a person may eat from it and not die. 51 I am the living bread that came down from heaven. If anyone eats from this bread he will live forever. The bread that I will give for the life of the world is my flesh.”

52 Then the Jews who were hostile to Jesus began to argue with one another, “How can this man give us his flesh to eat?” 53 Jesus said to them, “I tell you the solemn truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in yourselves. 54 The one who eats my flesh and drinks my blood has eternal life, and I will raise him up on the last day. 55 For my flesh is true food, and my blood is true drink. 56 The one who eats my flesh and drinks my blood resides in me, and I in him. 57 Just as the living Father sent me, and I live because of the Father, so the one who consumes me will live because of me. 58 This is the bread that came down from heaven; it is not like the bread your ancestors ate, but then later died. The one who eats this bread will live forever.”

59 Jesus said these things while he was teaching in the synagogue in Capernaum. 60 Then many of his disciples, when they heard these things, said, “This is a difficult saying! Who can understand it?” 61 When Jesus was aware that his disciples were complaining about this, he said to them, “Does this cause you to be offended? 62 Then what if you see the Son of Man ascending where he was before? 63 The Spirit is the one who gives life; human nature is of no help! The words that I have spoken to you are spirit and are life. 64 But there are some of you who do not believe.” (For Jesus had already known from the beginning who those were who did not believe, and who it was who would betray him.) 65 So Jesus added, “Because of this I told you that no one can come to me unless the Father has allowed him to come.”

66 After this many of his disciples quit following him and did not accompany him any longer. 67 So Jesus said to the twelve, “You don’t want to go away too, do you?” 68 Simon Peter answered him, “Lord, to whom would we go? You have the words of eternal life. 69 We have come to believe and to know that you are the Holy One of God!” 70 Jesus replied, “Didn’t I choose you, the twelve, and yet one of you is the devil?” 71 (Now he said this about Judas son of Simon Iscariot, for Judas, one of the twelve, was going to betray him.)
