They must receive Him who destroys corruption and abolishes death. For all this truly belongs and is proper to Life by nature.
Because they appealed to the manna given to their fathers in the wilderness from heaven, they did not accept the bread truly come down from heaven, that is, Christ.
Therefore He necessarily compares the type with the truth. Thus they might see that manna is not the heavenly bread.
Rather, the heavenly bread is the One whom the experience of reality shows to be such by nature.
Your fathers and ancestors, He says, ate the manna and paid the debt of bodily nature.
Through it they obtained the support of temporary life. By it they gave the body its daily nourishment, and they scarcely managed not to die immediately.
The clearest proof that it was not the truly heavenly bread, He says, is that those who ate it by no means attained immortality through it.
Likewise, the sign that the Son is, in the proper and true sense, the bread of life is this.
Those who have once tasted of Him, and through participation have in some way been united with Him, are shown to be above even the bonds of death.
We have already said much about this: manna is taken as an image or shadow of Christ and pointed to the bread of life. Yet it was not itself this bread of life.
The Psalmist seems to confirm this when he cries out in the Spirit, "He gave them bread from heaven; man ate the bread of angels" (Ps 77:24-25).
Perhaps these words may seem to have been spoken by the Spirit-bearing one about the Israelites. In reality this is not so. Rather, the meaning of the saying concerns us.
Indeed, is it not the height of absurdity and folly to think that the holy Angels in heaven, though they have received a bodiless nature, eat coarse food?
Do they need help to sustain life, like that required by this earthly body? I think nothing prevents us from thinking that, since they are spirits, they may need such food.
Clearly, it would be spiritual and noetic food. Why then is the bread of angels said to have been given to the ancestors of the Jews, if the prophet speaks the truth when he cries this out?
It is clear that manna was typological, in the image of Christ. He embraces and sustains all things in being, nourishes the Angels, and gives life to those on earth.
Therefore the prophet calls what was indicated in shadows by the name of the truth.
By the impossibility of holy Angels eating earthly food, he draws his hearers, even against their will, away from the crude thought, that is, from manna.
He leads them up to the spiritual understanding, that is, to Christ Himself, who is the bread even of the holy Angels themselves.
Thus, those who ate manna, He says, died. Plainly, they received from it no participation in any life.
It was not truly life-giving, but only a remedy against bodily hunger. It had the significance of a type of the truth.
But those who receive into themselves the bread of life will have immortality as their reward.
Completely freed from corruption and all its evils, they will be raised to the eternal and endless continuance of life according to Christ.
These considerations of ours are not hindered by the fact that those who enter into communion with Christ must still taste death according to the debt of nature.
Although they undergo what belongs to human nature by falling under this common end, nevertheless, as Paul says, they "live to God" (Rom 6:10-14, 8; cf. Gal 2:17-21).
They do so as those who are destined to live forever.
