John Chrysostom
Catena Aurea · Johannesevangelium 6
For my flesh is meat indeed, and my blood is drink indeed. He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him. As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me. This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever. These things said he in the synagogue, as he taught in Capernaum.
(Hom. xlvii. 1) Or, having given a promise of eternal life to those that eat Him, He says this to confirm it: He that eateth My flesh, and drinketh My blood, dwelleth in Me, and I in him.
