This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eats of this bread shall live forever.
All Commentaries on John 6:58 Go To John 6
Cyril of Alexandria
AD 444
Great (saith He) ought to be the effects of great things, and the gifts of the Grace from above, should appear God-befitting and worthy of the Divine Munificence. For if thou have wholly received in faith that the Bread came, down from heaven, let it produce continous life in them that long after it, and have the unceasing Operation of immortality. For this will be a clear proof of its being the Bread from heaven, that is from God: since we say that it befits the Eternal to give what is eternal, and not the enjoyment of temporary food, which is barely able to last for just the least moment. For one will no longer wisely suppose that that was the bread from God and from above, which our forefathers eating, were overcome by death, and repelled not the evil of corruption, and no wonder; for that was not the Bread which availeth to render immortal. Hence neither will it be rightly conceived and said by any to be from heaven. For it was a work befitting that which came down thence, to render the partakers of It superior to death and decay. By undoubted proof again will it be confirmed, that this was the Bread from Heaven, that to wit through Christ, i. e., His Body. For It makes him that tastes thereof to live for ever. Herein too is seen a great pledge of the Divine Nature, Which vouchsafes not to give a little thing, but everything wonderful, even surpassing our understanding, so as for the greatness of the Grace, to be even disbelieved by the more simple. For with so wealthy a Hand how should not the Will to give largely be present? Wherefore Paul too says in amazement, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God prepared for them that love Him. By little examples was the Law typifying great ones, having the shadow of the good things to come, not the very image of the things, as it is written: as in the food of manna is seen the Blessing that is through Christ. For the shadow of the good things to come was prefigured to them of old.
