Against the Heresies: St. Irenaeus of Lyon

Book I, Chapter 10

Unity of the faith of the Church throughout the whole world

1. The Church, though dispersed through the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith: [She believes] in one God, the Father Almighty, Maker of heaven, and earth, and the sea, and all things that are in them; and in one Christ Jesus, the Son of God, who became incarnate for our salvation; and in the Holy Spirit, who proclaimed through the prophets the dispensations of God, and the advents, and the birth from a virgin, and the passion, and the resurrection from the dead, and the ascension into heaven in the flesh of the beloved Christ Jesus, our Lord, and His [future] manifestation from heaven in the glory of the Father "to gather all things in one," and to raise up anew all flesh of the whole human race, in order that to Christ Jesus, our Lord, and God, and Saviour, and King, according to the will of the invisible Father, "every knee should bow, of things in heaven,, and things in earth, and things under the earth, and that every tongue should confess" to Him, and that He should execute just judgment towards all; that He may send "spiritual wickednesses," and the angels who transgressed and became apostates, together with the ungodly, and unrighteous, and wicked, and profane among men, into everlasting fire; but may, in the exercise of His grace, confer immortality on the righteous, and holy, and those who have kept His commandments, and have persevered in His love, some from the beginning [of their Christian course], and others from [the date of] their repentance, and may surround them with everlasting glory.

2. As I have already observed, the Church, having received this preaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it. She also believes these points [of doctrine] just as if she had but one soul, and one and the same heart, and she proclaims them, and teaches them, and hands them down, with perfect harmony, as if she possessed only one mouth. For, although the languages of the world are dissimilar, yet the import of the tradition is one and the same. For the Churches which have been planted in Germany do not believe or hand down anything different, nor do those in Spain, nor those in Gaul, nor those in the East, nor those in Egypt, nor those in Libya, nor those which have been established in the central regions of the world. But as the sun, that creature of God, is one and the same throughout the whole world, so also the preaching of the truth shineth everywhere, and enlightens all men that are willing to come to a knowledge of the truth. Nor will any one of the rulers in the Churches, however highly gifted he may be in point of eloquence, teach doctrines different from these (for no one is greater than the Master); nor, on the other hand, will he who is deficient in power of expression inflict injury on the tradition. For the faith being ever one and the same, neither does one who is able at great length to discourse regarding it, make any addition to it, nor does one, who can say but little diminish it.

3. It does not follow because men are endowed with greater and less degrees of intelligence, that they should therefore change the subject-matter [of the faith] itself, and should conceive of some other God besides Him who is the Framer, Maker, and Preserver of this universe, (as if He were not sufficient for them), or of another Christ, or another Only-begotten. But the fact referred to simply implies this, that one may [more accurately than another] bring out the meaning of those things which have been spoken in parables, and accommodate them to the general scheme of the faith; and explain [with special clearness] the operation and dispensation of God connected with human salvation; and show that God manifested longsuffering in regard to the apostasy of the angels who transgressed, as also with respect to the disobedience of men; and set forth why it is that one and the same God has made some things temporal and some eternal, some heavenly and others earthly; and understand for what reason God, though invisible, manifested Himself to the prophets not under one form, but differently to different individuals; and show why it was that more covenants than one were given to mankind; and teach what was the special character of each of these covenants; and search out for what reason "God hath concluded every man in unbelief, that He may have mercy upon all;" and gratefully describe on what account the Word of God became flesh and suffered; and relate why the advent of the Son of God took place in these last times, that is, in the end, rather than in the beginning [of the world]; and unfold what is contained in the Scriptures concerning the end [itself], and things to come; and not be silent as to how it is that God has made the Gentiles, whose salvation was despaired of, fellow-heirs, and of the same body, and partakers with the saints; and discourse how it is that "this mortal body shall put on immortality, and this corruptible shall put on incorruption;" and proclaim in what sense [God] says, "'That is a people who was not a people; and she is beloved who was not beloved;" and in what sense He says that "more are the children of her that was desolate, than of her who possessed a husband." For in reference to these points, and others of a like nature, the apostle exclaims: "Oh! the depth of the riches both of the wisdom and knowledge of God; how unsearchable are His judgments, and His ways past finding out!" But [the superior skill spoken of] is not found in this, that any one should, beyond the Creator and Framer [of the world], conceive of the Enthymesis of an erring Aeon, their mother and his, and should thus proceed to such a pitch of blasphemy; nor does it consist in this, that he should again falsely imagine, as being above this [fancied being], a Pleroma at one time supposed to contain thirty, and at another time an innumerable tribe of Aeons, as these teachers who are destitute of truly divine wisdom maintain; while the Catholic Church possesses one and the same faith throughout the whole world, as we have already said.

Book V, Chapter 2

When Christ visited us in his grace, he did not come to what did not belong to him: also, by shedding his true blood for us, and exhibiting to us his true flesh in the Eucharist, he conferred upon our flesh the capacity of salvation.

1. And vain likewise are those who say that God came to those things which did not belong to Him, as if covetous of another's property; in order that He might deliver up that man who had been created by another, to that God who had neither made nor formed anything, but who also was deprived from the beginning of His own proper formation of men. The advent, therefore, of Him whom these men represent as coming to the things of others, was not righteous; nor did He truly redeem us by His own blood, if He did not really become man, restoring to His own handiwork what was said [of it] in the beginning, that man was made after the image and likeness of God; not snatching away by stratagem the property of another, but taking possession of His own in a righteous and gracious manner. As far as concerned the apostasy, indeed, He redeems us righteously from it by His own blood; but as regards us who have been redeemed, [He does this] graciously. For we have given nothing to Him previously, nor does He desire anything from us, as if He stood in need of it; but we do stand in need of fellowship with Him. And for this reason it was that He graciously poured Himself out, that He might gather us into the bosom of the Father.

2. But vain in every respect are they who despise the entire dispensation of God, and disallow the salvation of the flesh, and treat with contempt its regeneration, maintaining that it is not capable of incorruption. But if this indeed do not attain salvation, then neither did the Lord redeem us with His blood, nor is the cup of the Eucharist the communion of His blood, nor the bread which we break the communion of His body. For blood can only come from veins and flesh, and whatsoever else makes up the substance of man, such as the Word of God was actually made. By His own blood he redeemed us, as also His apostle declares, "In whom we have redemption through His blood, even the remission of sins." And as we are His members, we are also nourished by means of the creation (and He Himself grants the creation to us, for He causes His sun to rise, and sends rain when He wills ). He has acknowledged the cup (which is a part of the creation) as His own blood, from which He bedews our blood; and the bread (also a part of the creation) He has established as His own body, from which He gives increase to our bodies.

3. When, therefore, the mingled cup and the manufactured bread receives the Word of God, and the Eucharist of the blood and the body of Christ is made, from which things the substance of our flesh is increased and supported, how can they affirm that the flesh is incapable of receiving the gift of God, which is life eternal, which [flesh] is nourished from the body and blood of the Lord, and is a member of Him? -- even as the blessed Paul declares in his Epistle to the Ephesians, that "we are members of His body, of His flesh, and of His bones." He does not speak these words of some spiritual and invisible man, for a spirit has not bones nor flesh; but [he refers to] that dispensation [by which the Lord became] an actual man, consisting of flesh, and nerves, and bones -- that [flesh] which is nourished by the cup which is His blood, and receives increase from the bread which is His body. And just as a cutting from the vine planted in the ground fructifies in its season, or as a corn of wheat falling into the earth and becoming decomposed, rises with manifold increase by the Spirit of God, who contains all things, and then, through the wisdom of God, serves for the use of men, and having received the Word of God, becomes the Eucharist, which is the body and blood of Christ; so also our bodies, being nourished by it, and deposited in the earth, and suffering decomposition there, shall rise at their appointed time, the Word of God granting them resurrection to the glory of God, even the Father, who freely gives to this mortal immortality, and to this corruptible incorruption, because the strength of God is made perfect in weakness, in order that we may never become puffed up, as if we had life from ourselves, and exalted against God, our minds becoming ungrateful; but learning by experience that we possess eternal duration from the excelling power of this Being, not from our own nature, we may neither undervalue that glory which surrounds God as He is, nor be ignorant of our own nature, but that we may know what God can effect, and what benefits man receives, and thus never wander from the true comprehension of things as they are, that is, both with regard to God and with regard to man. And might it not be the case, perhaps, as I have already observed, that for this purpose God permitted our resolution into the common dust of mortality, that we, being instructed by every mode, may be accurate in all things for the future, being ignorant neither of God nor of ourselves?

Book V, Chapter 3

The power and glory of God shine forth in the weakness of human flesh, as he will render our body a participator of the resurrection and of immortality, although He has formed it from the dust of the earth; He will also bestow upon it the enjoyment of immortality, just as He grants it this short life in common with the soul.

1. The Apostle Paul has, moreover, in the most lucid manner, pointed out that man has been delivered over to his own infirmity, lest, being uplifted, he might fall away from the truth. Thus he says in the second [Epistle] to the Corinthians: "And lest I should be lifted up by the sublimity of the revelations, there was given unto me a thorn in the flesh, the messenger of Satan to buffet me. And upon this I besought the Lord three times, that it might depart from me. But he said unto me, My grace is sufficient for thee; for strength is made perfect in weakness. Gladly therefore shall I rather glory in infirmities, that the power of Christ may dwell in me." What, therefore? (as some may exclaim:) did the Lord wish, in that case, that His apostles should thus undergo buffering, and that he should endure such infirmity? Even so it was; the word says it. For strength is made perfect in weakness, rendering him a better man who by means of his infirmity becomes acquainted with the power of God. For how could a man have learned that he is himself an infirm being, and mortal by nature, but that God is immortal and powerful, unless he had learned by experience what is in both? For there is nothing evil in learning one's infirmities by endurance; yea, rather, it has even the beneficial effect of preventing him from forming an undue opinion of his own nature (non aberrare in natura sua). But the being lifted up against God, and taking His glory to one's self, rendering man ungrateful, has brought much evil upon him. [And thus, I say, man must learn both things by experience], that he may not be destitute of truth and love either towards himself or his Creator. But the experience of both confers upon him the true knowledge as to God and man, and increases his love towards God. Now, where there exists an increase of love, there a greater glory is wrought out by the power of God for those who love Him.

2. Those men, therefore, set aside the power of God, and do not consider what the word declares, when they dwell upon the infirmity of the flesh, but do not take into consideration the power of Him who raises it up from the dead. For if He does not vivify what is mortal, and does not bring back the corruptible to incorruption, He is not a God of power. But that He is powerful in all these respects, we ought to perceive from our origin, inasmuch as God, taking dust from the earth, formed man. And surely it is much more difficult and incredible, from non-existent bones, and nerves, and veins, and the rest of man's organization, to bring it about that all this should be, and to make man an animated and rational creature, than to re-integrate again that which had been created and then afterwards decomposed into earth (for the reasons already mentioned), having thus passed into those [elements] from which man, who had no previous existence, was formed. For He who in the beginning caused him to have being who as yet was not, just when He pleased, shall much more reinstate again those who had a former existence, when it is His will [that they should inherit] the life granted by Him. And that flesh shall also be found fit for and capable of receiving the power of God, which at the beginning received the skilful touches of God; so that one part became the eye for seeing; another, the ear for hearing; another, the hand for feeling and working; another, the sinews stretched out everywhere, and holding the limbs together; another, arteries and veins, passages for the blood and the air; another, the various internal organs; another, the blood, which is the bond of union between soul and body. But why go [on in this strain]? Numbers would fail to express the multiplicity of parts in the human frame, which was made in no other way than by the great wisdom of God. But those things which partake of the skill and wisdom of God, do also partake of His power.

3. The flesh, therefore, is not destitute [of participation] in the constructive wisdom and power of God. But if the power of Him who is the bestower of life is made perfect in weakness -- that is, in the flesh -- let them inform us, when they maintain the incapacity of flesh to receive the life granted by God, whether they do say these things as being living men at present, and partakers of life, or acknowledge that, having no part in life whatever, they are at the present moment dead men. And if they really are dead men, how is it that they move about, and speak, and perform those other functions which are not the actions of the dead, but of the living? But if they are now alive, and if their whole body partakes of life, how can they venture the assertion that the flesh is not qualified to be a partaker of life, when they do confess that they have life at the present moment? It is just as if anybody were to take up a sponge full of water, or a torch on fire, and to declare that the sponge could not possibly partake of the water, or the torch of the fire. In this very manner do those men, by alleging that they are alive and bear life about in their members, contradict themselves afterwards, when they represent these members as not being capable of [receiving] life. But if the present temporal life, which is of such an inferior nature to eternal life, can nevertheless effect so much as to quicken our mortal members, why should not eternal life, being much more powerful than this, vivify the flesh, which has already held converse with, and been accustomed to sustain, life? For that the flesh can really partake of life, is shown from the fact of it; being alive; for it lives on, as long as it is God's purpose that it should do so. It is manifest, too, that God has the power to confer life upon it, inasmuch as He grants life to us who are in existence. And, therefore, since the Lord has power to infuse life into what He has fashioned, and since the flesh is capable of being quickened, what remains to prevent its participating in incorruption, which is a blissful and never-ending life granted by God?
