51 I am the living bread which has come from heaven: if any man takes this bread for food he will have life for ever: and more than this, the bread which I will give is my flesh which I will give for the life of the world.

52 Then the Jews had an angry discussion among themselves, saying, How is it possible for this man to give us his flesh for food?

53 Then Jesus said to them, Truly I say to you, If you do not take the flesh of the Son of man for food, and if you do not take his blood for drink, you have no life in you.

54 He who takes my flesh for food and my blood for drink has eternal life: and I will take him up from the dead at the last day.

55 My flesh is true food and my blood is true drink.

56 He who takes my flesh for food and my blood for drink is in me and I in him.

57 As the living Father has sent me, and I have life because of the Father, even so he who takes me for his food will have life because of me.

58 This is the bread which has come down from heaven. It is not like the food which your fathers had: they took of the manna, and are dead; but he who takes this bread for food will have life for ever.

João 6:51-58
