John 6:33

"The bread of God is He which cometh down from heaven, and giveth life unto the world." Not, saith He, to Jews alone, but to all the "world," not mere food, but "life," another and an altered "life." He calleth it "life," because they all were dead in sins. Yet they still kept downward bent, saying, "Give us this bread." Then He, to rebuke them, because while they supposed that the food was material they ran to Him, but not when they learned that it was a spiritual kind.

Not to the physical world, but to men, its inhabitants.

Who by the humanity, which was assumed, came down from heaven, and by the divinity, which assumed it, gives life to the world.

But this bread, being essentially life, (for He is the Son of the living Father,) in quickening all things, does but what is natural to Him to do. For as natural bread supports our weak flesh, so Christ, by the operations of the Spirit, gives life to the soul; and even incorruption to the body, (for at the resurrection the body will be made incorruptible.) Wherefore He says, that He giveth life unto the world.

Our Lord Jesus Christ sets Himself above Moses: for Moses durst not say of himself that he gave bread from heaven; but that God gave it. Ye propose to me Moses: "Verily, verily, I say unto you, Moses gave you not that bread from heaven, but my Father giveth you the true bread from heaven." Because Moses gave not, but the Lord gave, why do you prefer Moses to me? "But my Father giveth you the true bread from heaven." Well, is this bread that the Father giveth, Moses, or something given by Moses? "For the bread of God is that which cometh down from heaven, and giveth life unto the world." The bread of God is that which cometh down from heaven. This bread the manna signified, this bread the altar of God signifies.
