John 6:44-58

No one is able to come to me, unless the Father, who has sent me, has drawn him. And I will raise him up on the last day. It has been written in the Prophets: 'And they shall all be taught by God.' Everyone who has listened and learned from the Father comes to me. Not that anyone has seen the Father, except he who is from God; this one has seen the Father. Amen, amen, I say to you, whoever believes in me has eternal life. I am the bread of life. Your fathers ate manna in the desert, and they died. This is the bread which descends from heaven, so that if anyone will eat from it, he may not die. I am the living bread, who descended from heaven. If anyone eats from this bread, he shall live in eternity. And the bread that I will give is my flesh, for the life of the world." Therefore, the Jews debated among themselves, saying, "How can this man give us his flesh to eat?" And so, Jesus said to them: "Amen, amen, I say to you, unless you eat the flesh of the Son of man and drink his blood, you will not have life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up on the last day. For my flesh is true food, and my blood is true drink. Whoever eats my flesh and drinks my blood abides in me, and I in him. Just as the living Father has sent me and I live because of the Father, so also whoever eats me, the same shall live because of me.
