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) For if it was possible without harvest or fruit of the earth, or any such thing, to preserve the lives of the Israelites of old for forty years, much more will He be able to do this with that spiritual food, of which the manna is the type. He knew how precious a thing life was in men’s eyes, and therefore repeats His promise of life often; just as the Old Testament had done; (Exod. 20:12) only that it only offered length of life, He life without end. (Deut. 22:7) This promise was an abolition of that sentence of death, which sin had brought upon us. These things said He in the synagogue, as He taught in Capernaum; (1 Kings 3:14) where many displays of His power took place. (Ps. 21:4; 91:16) He taught in the synagogue and in the temple, (Prov. 3:2) with the view of attracting the multitude, and as a sign that He was not acting in opposition to the Father.
