1Cor 15:48

“The flesh, therefore, when destitute of the Spirit of God, is dead, not having life, and cannot possess the kingdom of God: [it is as] irrational blood, like water poured out upon the ground. And therefore he says, "As is the earthy, such are they that are earthy." But where the Spirit of the Father is, there is a living man; [there is] the rational blood preserved by God for the avenging [of those that shed it]; [there is] the flesh possessed by the Spirit, forgetful indeed of what belongs to it, and adopting the quality of the Spirit, being made conformable to the Word of God. And on this account he (the apostle) declares, "As we have borne the image of him who is of the earth, we shall also bear the image of Him who is from heaven." What, therefore, is the earthly? That which was fashioned. And what is the heavenly? The Spirit. As therefore he says, when we were destitute of the celestial Spirit, we walked in former times in the oldness of the flesh, not obeying God; so now let us, receiving the Spirit, walk in newness of life, obeying God. Inasmuch, therefore, as without the Spirit of God we cannot be saved, the apostle exhorts us through faith and chaste conversation to preserve the Spirit of God, lest, having become non-participators of the Divine Spirit, we lose the kingdom of heaven; and he exclaims, that flesh in itself, and blood, cannot possess the kingdom God.”

“"As is the earthy, such are they also that are earthy; and as is the heavenly, such are they also that are heavenly." Such (does he mean), in substance; or first of all in training, and afterwards in the dignity and worth which that training aimed at acquiring? Not in substance, however, by any means will the earthy and the heavenly be separated, designated as they have been by the apostle once for all, as men.”

“The first man was made from the slime of the earth. The second man came from heaven. By using the word man, he taught the birth of this man from the virgin, who in fulfilling her function as a mother acted in accordance with the nature of her sex in the conception and birth of the man. And when he asserted that the second man was from heaven, he testified that his origin was from the appearance of the Holy Spirit who came upon the virgin. Thus precisely while he was a man, he was also from heaven. The birth of this man was from the virgin. The conception was from the Spirit.”

“"As is the earthy, such are they also that are earthy:" so shall they perish and have an end. "As is the heavenly, such are they also that are heavenly:" so shall they abide immortal and glorious. What then? Did not This Man too die? He died indeed, but received no injury therefrom, yea rather by this He put an end to death. Seest thou how on this part of his subject also, he makes use of death to establish the doctrine of the resurrection? "For having, as I said before, the beginning and the head," so he speaks, "doubt not of the whole body." Moreover also he frames hereby his advice concerning the best way of living, proposing standards of a lofty and severe life and of that which is not such, and bringing forward the principles of both these, of the one Christ, but of the other Adam. Therefore neither did he simply say, "of the earth," but "earthy," i.e., "gross, nailed down to things present:" and again with respect to Christ the reverse, "the Lord from heaven." But if any should say, "therefore the Lord hath not a body because He is said to be 'from heaven,'" although what is said before is enough to stop their mouths: yet nothing hinders our silencing them from this consideration also: viz. what is, "the Lord from heaven?" Doth he speak of His nature, or His most perfect life? It is I suppose evident to every one that he speaks of His life.”

“If you do not like the Christian faith, say so. But you will not find another Christian faith. There is one man unto life; there is one unto death. The one is only man; the other is God and man. Through the one the world was made the enemy of God. Through the other those chosen from the world are reconciled to God. For "As in Adam all die, so in Christ all will be made alive." Therefore even as we have borne the image of the earthly, let us also bear the image of the heavenly. Whoever tries to undermine these foundations of the Christian faith will himself be destroyed, but they will remain firm.”

“The Lord who was heavenly became earthly that he might make heavenly those who were earthly. From immortal he became mortal by taking the form of a servant, not by changing the nature of the Lord, that he might make immortal those who were mortal by imparting the grace of the Lord, not by retaining the offense of the servant.”

“That is, they will also perish and die; or those who were attached to the earth will die the death of sin. That is, they will likewise be immortal and glorious. For although the second Adam also died, He died in order to destroy death. Or: those who led a godlike life will be glorified as those who set their minds on heavenly things.”

“996. – Then when he says, As is the man of dust, he shows the derivation of the likeness of these principles from each one: first, in common; secondly, he divides it into parts (v. 49). 997. – He says, therefore, As is the man of dust. As if to say: because the first man was of the earth and mortal, so it follows that all were both of the earth and mortal: "For as in Adam all die" (1 Cor 15:22); "Adam was my exemplar" (Zech. 13:5, Vulgate). Because the second man was from heaven, i.e., spiritual and immortal, so we all will be both immortal and spiritual: "For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his" (Rom. 6:5).”
