51I am the living bread that came down from Heaven. Whoever eats of this bread will live forever. The bread that I will give for the life of the world is my flesh.”
52Therefore the Jews argued among themselves, saying, “How can this Man give us His flesh to eat?”
53Then Jesus told them, “Most assuredly, I tell you, unless you eat the flesh of the Son of Man, and drink His blood, you have no life in you.
54Whoever eats my flesh and drinks my blood has eternal life, and I will raise that person up at the last day,
55for my flesh is true food, and my blood is true drink.
56One who eats my flesh and drinks my blood lives in me, and I in that person.
57Just as the living Father sent me, and I live because of the Father, so the one who feeds on me will live because of me.
58This is the bread which came down from Heaven, not like the manna your forefathers ate, and died. A person who eats this bread will live forever.”
59He said this while teaching in the synagogue at Capernaum.
60Therefore when many of His disciples heard this, they said, “This is a hard teaching. Who can stand to hear it?”
61Jesus, aware that his disciples were complaining about this, asked them, “Does this offend you?
62What if you saw the Son of Man ascend to where He was before?
63The Spirit gives life. The flesh profits nothing. The words that I speak to you are spirit and life.
64Yet there are some of you who don’t believe.” Jesus knew from the beginning who didn’t believe, and who would betray Him.
65He said, “For this reason I have told you, that no one can come to me, unless it has been granted by the Father.”
66Because of this, many of His disciples turned back and didn’t walk with him any more.
67Then Jesus asked the twelve, “Do you want to go away, too?”
68Simon Peter answered Him, “Lord, who will we go to? You have words of eternal life.
