Chapter VII.-Inasmuch as Christ Did Rise in Our Flesh, It Follows that We Shall Be Also Raised in the Same; Since the Resurrection Promised to Us Should Not Be Referred to Spirits Naturally Immortal, But to Bodies in Themselves Mortal.
1. In the same manner, therefore, as Christ did rise in the substance of flesh, and pointed out to His disciples the mark of the nails and the opening in His side 35 (now these are the tokens of that flesh which rose from the dead), so "shall He also," it is said, "raise us up by His own power." 36 And again to the Romans he says, "But if the Spirit of Him that raised up Jesus from the dead dwell in you, He that raised up Christ from the dead shall also quicken your mortal bodies." 37 What, then, are mortal bodies? Can they be souls? Nay, for souls are incorporeal when put in comparison with mortal bodies; for God "breathed into the face of man the breath of life, and man became a living soul." Now the breath of life is an incorporeal thing. And certainly they cannot maintain that the very breath of life is mortal. Therefore David says, "My soul also shall live to Him," 38 just as if its substance were immortal. Neither, on the other hand, can they say that the spirit is the mortal body. What therefore is there left to which we may apply the term "mortal body," unless it be the thing that was moulded, that is, the flesh, of which it is also said that God will vivify it? For this it is which dies and is decomposed, but not the soul or the spirit. For to die is to lose vital power, and to become henceforth breathless, inanimate, and devoid of motion, and to melt away into those [component parts] from which also it derived the commencement of [its] substance. But this event happens neither to the soul, for it is the breath of life; nor to the spirit, for the spirit is simple and not composite, so that it cannot be decomposed, and is itself the life of those who receive it. We must therefore conclude that it is in reference to the flesh that death is mentioned; which [flesh], after the soul's departure, becomes breathless and inanimate, and is decomposed gradually into the earth from which it was taken. This, then, is what is mortal. And it is this of which he also says," He shall also quicken your mortal bodies." And therefore in reference to it he says, in the first [Epistle] to the Corinthians: "So also is the resurrection of the dead: it is sown in corruption, it rises in incorruption." 39 For he declares, "That which thou sowest cannot be quickened, unless first it die." 40
2. But what is that which, like a grain of wheat, is sown in the earth and decays, unless it be the bodies which are laid in the earth, into which seeds are also cast? And for this reason he said, "It is sown in dishonour, it rises in glory." 41 For what is more ignoble than dead flesh? Or, on the other hand, what is more glorious than the same when it arises and partakes of incorruption? "It is sown in weakness, it is raised in power: " 42 in its own weakness certainly, because since it is earth it goes to earth; but [it is quickened] by the power of God, who raises it from the dead. "It is sown an animal body, it rises a spiritual body." 43 He has taught, beyond all doubt, that such language was not used by him, either with reference to the soul or to the spirit, but to bodies that have become corpses. For these are animal bodies, that is, [bodies] which partake of life, which when they have lost, they succumb to death; then, rising through the Spirit's instrumentality, they become spiritual bodies, so that by the Spirit they possess a perpetual life. "For now," he says, "we know in part, and we prophesy in part, but then face to face." 44 And this it is which has been said also by Peter: "Whom having not seen, ye love; in whom now also, not seeing, ye believe; and believing, ye shall rejoice with joy unspeakable." 45 For our face shall see the face of the Lord 46 and shall rejoice with joy unspeakable,-that is to say, when it shall behold its own Delight.
Irenaeus even discussed how some whom he referred to as "heretics" were attempting to use the phrase "flesh and blood" from 1 Corinthians in order to attempt to overturn the resurrection of the flesh.

Chapter IX.-Showing How that Passage of the Apostle Which the Heretics Pervert, Should Be Understood; Viz., "Flesh and Blood Shall Not Possess the Kingdom of God."
1. Among the other [truths] proclaimed by the apostle, there is also this one, "That flesh and blood cannot inherit the kingdom of God." 58 This is [the passage] which is adduced by all the heretics in support of their folly, with an attempt to annoy us, and to point out that the handiwork of God is not saved. They do not take this fact into consideration, that there are three things out of which, as I have shown, the complete man is composed-flesh, soul, and spirit. One of these does indeed preserve and fashion [the man]-this is the spirit; while as to another it is united and formed-that is the flesh; then [comes] that which is between these two-that is the soul, which sometimes indeed, when it follows the spirit, is raised up by it, but sometimes it sympathizes with the flesh, and falls into carnal lusts. Those then, as many as they be, who have not that which saves and forms [us] into life [eternal], shall be, and shall be called, [mere] flesh and blood; for these are they who have not the Spirit of God in themselves. Wherefore men of this stamp are spoken of by the Lord as "dead; "for, says He, "Let the dead bury their dead," 59 because they have not the Spirit which quickens man.
2. On the other hand, as many as fear God and trust in His Son's advent, and who through faith do establish the Spirit of God in their hearts,-such men as these shall be properly called both "pure," and "spiritual," and "those living to God," because they possess the Spirit of the Father, who purifies man, and raises him up to the life of God. For as the Lord has testified that "the flesh is weak," so [does He also say] that "the spirit is willing." 60 For this latter is capable of working out its own suggestions. If, therefore, any one admix the ready inclination of the Spirit to be, as it were, a stimulus to the infirmity of the flesh, it inevitably follows that what is strong will prevail over the weak, so that the weakness of the flesh will be absorbed by the strength of the Spirit; and that the man in whom this takes place cannot in that case be carnal, but Spiritual, because of the fellowship of the Spirit. Thus it is, therefore, that the martyrs bear their witness, and despise death, not after the infirmity of the flesh, but because of the readiness of the Spirit. For when the infirmity of the flesh is absorbed, it exhibits the Spirit as powerful; and again, when the Spirit absorbs the weakness [of the flesh], it possesses the flesh as an inheritance in itself, and from both of these is formed a living man,-living, indeed, because he partakes of the Spirit, but man, because of the substance of flesh.
3. 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." 61 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." 62 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.
4. If, however, we must speak strictly, [we would say that] the flesh does not inherit, but is inherited; as also the Lord declares, "Blessed are the meek, for they shall possess the earth by inheritance; " 63 as if in the [future] kingdom, the earth, from whence exists the substance Of our flesh, is to be possessed by inheritance. This is the reason for His wishing the temple (i.e., the flesh) to be clean, that the Spirit of God may take delight therein, as a bridegroom with a bride. As, therefore, the bride cannot [be said] to wed, but to be wedded, when the bridegroom comes and takes her, so also the flesh cannot by itself possess the kingdom of God by inheritance; but it can be taken for an inheritance into the kingdom of God. For a living person inherits the goods of the deceased; and it is one thing to inherit, another to be inherited. The former rules, and exercises power over, and orders the things inherited at his will; but the latter things are in a state of subjection, are under order, and are ruled over by him who has obtained the inheritance. What, therefore, is it that lives? The Spirit of God, doubtless. What, again, are the possessions of the deceased? The various parts of the man, surely, which rot in the earth. But these are inherited by the Spirit when they are translated into the kingdom of heaven. For this cause, too, did Christ die. that the Gospel covenant being manifested and known to the whole world, might in the first place set free His slaves; and then afterwards, as I have already shown, might constitute them heirs of His property, when the Spirit possesses them by inheritance. For he who lives inherits, but the flesh is inherited. In order that we may not lose life by losing that Spirit which possesses us, the apostle, exhorting us to the communion of the Spirit, has said, according to reason, in those words already quoted, "That flesh and blood cannot inherit the kingdom of God." Just as if he were to say, "Do not err; for unless the Word of God dwell with, and the Spirit of the Father be in you, and if ye shall live frivolously and carelessly as if ye were this only, viz., mere flesh and blood, ye cannot inherit the kingdom of God."
