47 Truly, truly I say to you, the one who believes has eternal life.
48 I am the bread of life.
49 Your fathers ate the manna in the wilderness and they died.
50 This is the bread that comes down from heaven so that someone 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. And the bread that I will give for the life of the world is my flesh.”
52 So the Jews began to quarrel among themselves, saying, “How can this man give us his flesh to eat?”
53 Then 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 do not have life in yourselves!
