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.
Except you eat and drink, etc… To receive the body and blood of Christ, is a divine precept, insinuated in this text; which the faithful fulfil, though they receive but in one kind; because in one kind they receive both body and blood, which cannot be separated from each other. Hence, life eternal is here promised to the worthy receiving, though but in one kind. Ver. 52. If any man eat of this bread, he shall live for ever; and the bread that I will give, is my flesh for the life of the world. Ver. 58. He that eateth me, the same also shall live by me. Ver. 59. He that eateth this bread, shall liver for ever.
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?
