From John Chapter 6
6:54. Then Jesus said to them: Amen, amen, I say unto you: except you eat the flesh of the Son of man and drink his blood, you shall not have life in you.
6:55. He that eateth my flesh and drinketh my blood hath everlasting life: and I will raise him up in the last day.
6:56. For my flesh is meat indeed: and my blood is drink indeed.
6:57. He that eateth my flesh and drinketh my blood abideth in me: and I in him.
6:58. As the living Father hath sent me and I live by the Father: so he that eateth me, the same also shall live by me.
6:59. This is the bread that came down from heaven. Not as your fathers did eat manna and are dead. He that eateth this bread shall live for ever.
6:60. These things he said, teaching in the synagogue, in Capharnaum.
6:61. Many therefore of his disciples, hearing it, said: This saying is hard; and who can hear it?
6:62. But Jesus, knowing in himself that his disciples murmured at this, said to them: Doth this scandalize you?
6:63. If then you shall see the Son of man ascend up where he was before?
6:64. It is the spirit that quickeneth: the flesh profiteth nothing. The words that I have spoken to you are spirit and life.
