Irenaeus: Against Heresies, Books I–V

1. As regards His greatness, therefore, it is not possible to know God, for it is impossible that the Father can be measured; but as regards His love (for this it is which leads us to God by His Word), when we obey Him, we do always learn that there is so great a God, and that it is He who by Himself has established, and selected, and adorned, and contains all things; and among the all things, both ourselves and this our world. We also then were made, along with those things which are contained by Him. And this is He of whom the Scripture says, “And God formed man, taking clay of the earth, and breathed into his face the breath of life.” ^[1] It was not angels, therefore, who made us, nor who formed us, neither had angels power to make an image of God, nor any one else, except the Word of the Lord, nor any Power remotely distant from the Father of all things. For God did not stand in need of these [beings], in order to the accomplishing of what He had Himself determined with Himself beforehand should be done, as if He did not possess His own hands. For with Him were always present the Word and Wisdom, the Son and the Spirit, by whom and in whom, freely and spontaneously, He made all things, to whom also He speaks, saying, “Let Us make man after Our image and likeness;” ^[2] He taking from Himself the substance of the creatures [formed], and the pattern of things made, and the type of all the adornments in the world.

2. Truly, then, the Scripture declared, which says, “First ^[3] of all believe that there is one God, who has established all things, and completed them, and having caused that from what had no being, all things should come into existence:” He who contains all things, and is Himself contained by no one. Rightly also has Malachi said among the prophets: “Is it not one God who hath established us? Have we not all one Father?” ^[4] In accordance with this, too, does the apostle say, “There is one God, the Father, who is above all, and in us all.” ^[5] Likewise does the Lord also say: “All things are delivered to Me by My Father;” ^[6] manifestly by Him who made all things; for He did not deliver to Him the things of another, but His own. But in all things [it is implied that] nothing has been kept back [from Him], and for this reason the same person is the Judge of the living and the dead; “having the key of David: He shall open, and no man shall shut: He shall shut, and no man shall open.” ^[7] For no one was able, either in heaven or in earth, or under the earth, to open the book of the Father, or to behold Him, with the exception of the Lamb who was slain, and who redeemed us with His own blood, receiving power over all things from the same God who made all things by the Word, and adorned them by [His] Wisdom, when “the Word was made flesh;” that even as the Word of God had the sovereignty in the heavens, so also might He have the sovereignty in earth, inasmuch as [He was] a righteous man, “who did no sin, neither was there found guile in His mouth;” ^[8] and that He might have the pre-eminence over those things which are under the earth, He Himself being made “the first-begotten of the dead;” ^[9] and that all things, as I have already said, might behold their King; and that the paternal light might meet with and rest upon the flesh of our Lord, and come to us from His resplendent flesh, and that thus man might attain to immortality, having been invested with the paternal light.

3. I have also largely demonstrated, that the Word, namely the Son, was always with the Father; and that Wisdom also, which is the Spirit, was present with Him, anterior to all creation, He declares by Solomon: “God by Wisdom founded the earth, and by understanding hath He established the heaven. By His knowledge the depths burst forth, and the clouds dropped down the dew.” ^[10] And again: “The Lord created me the beginning of His ways in His work: He set me up from everlasting, in the beginning, before He made the earth, before He established the depths, and before the fountains of waters gushed forth; before the mountains were made strong, and before all the hills, He brought me forth.” ^[11] And again: “When He prepared the heaven, I was with Him, and when He established the fountains of the deep; when He made the foundations of the earth strong, I was with Him preparing [them]. I was He in whom He rejoiced, and throughout all time I was daily glad before His face, when He rejoiced at the completion of the world, and was delighted in the sons of men.” ^[12]

4. There is therefore one God, who by the Word and Wisdom created and arranged all things; but this is the Creator (Demiurge) who has granted this world to the human race, and who, as regards His greatness, is indeed unknown to all who have been made by Him (for no man has searched out His height, either among the ancients who have gone to their rest, or any of those who are now alive); but as regards His love, He is always known through Him by whose means He ordained all things. Now this is His Word, our Lord Jesus Christ, who in the last times was made a man among men, that He might join the end to the beginning, that is, man to God. Wherefore the prophets, receiving the prophetic gift from the same Word, announced His advent according to the flesh, by which the blending and communion of God and man took place according to the good pleasure of the Father, the Word of God foretelling from the beginning that God should be seen by men, and hold converse with them upon earth, should confer with them, and should be present with His own creation, saving it, and becoming capable of being perceived by it, and freeing us from the hands of all that hate us, that is, from every spirit of wickedness; and causing us to serve Him in holiness and righteousness all our days, ^[13] in order that man, having embraced the Spirit of God, might pass into the glory of the Father.

5. These things did the prophets set forth in a prophetical manner; but they did not, as some allege, [proclaim] that He who was seen by the prophets was a different [God], the Father of all being invisible. Yet this is what those [heretics] declare, who are altogether ignorant of the nature of prophecy. For prophecy is a prediction of things future, that is, a setting forth beforehand of those things which shall be afterwards. The prophets, then, indicated beforehand that God should be seen by men; as the Lord also says, “Blessed are the pure in heart, for they shall see God.” ^[14] But in respect to His greatness, and His wonderful glory, “no man shall see God and live,” ^[15] for the Father is incomprehensible; but in regard to His love, and kindness, and as to His infinite power, even this He grants to those who love Him, that is, to see God, which thing the prophets did also predict. “For those things that are impossible with men, are possible with God.” ^[16] For man does not see God by his own powers; but when He pleases He is seen by men, by whom He wills, and when He wills, and as He wills. For God is powerful in all things, having been seen at that time indeed, prophetically through the Spirit, and seen, too, adoptively through the Son; and He shall also be seen paternally in the kingdom of heaven, the Spirit truly preparing man in the Son ^[17] of God, and the Son leading him to the Father, while the Father, too, confers [upon him] incorruption for eternal life, which comes to every one from the fact of his seeing God. For as those who see the light are within the light, and partake of its brilliancy; even so, those who see God are in God, and receive of His splendour. But [His] splendour vivifies them; those, therefore, who see God, do receive life. And for this reason, He, [although] beyond comprehension, and boundless and invisible, rendered Himself visible, and comprehensible, and within the capacity of those who believe, that He might vivify those who receive and behold Him through faith. ^[18] For as His greatness is past finding out, so also His goodness is beyond expression; by which having been seen, He bestows life upon those who see Him. It is not possible to live apart from life, and the means of life is found in fellowship with God; but fellowship with God is to know God, and to enjoy His goodness.

6. Men therefore shall see God, that they may live, being made immortal by that sight, and attaining even unto God; which, as I have already said, was declared figuratively by the prophets, that God should be seen by men who bear His Spirit [in them], and do always wait patiently for His coming. As also Moses says in Deuteronomy, “We shall see in that day that God will talk to man, and he shall live.” ^[19] For certain of these men used to see the prophetic Spirit and His active influences poured forth for all kinds of gifts; others, again, [beheld] the advent of the Lord, and that dispensation which obtained from the beginning, by which He accomplished the will of the Father with regard to things both celestial and terrestrial; and others [beheld] paternal glories adapted to the times, and to those who saw and who heard them then, and to all who were subsequently to hear them. Thus, therefore, was God revealed; for God the Father is shown forth through all these [operations], the Spirit indeed working, and the Son ministering, while the Father was approving, and man’s salvation being accomplished. As He also declares through Hosea the prophet: “I,” He says, “have multiplied visions, and have used similitudes by the ministry (in manibus) of the prophets.” ^[20] But the apostle expounded this very passage, when he said, “Now there are diversities of gifts, but the same Spirit; and there are differences of ministrations, but the same Lord; and there are diversities of operations, but it is the same God which worketh all in all. But the manifestation of the Spirit is given to every man to profit withal.” ^[21] But as He who worketh all things in all is God, [as to the points] of what nature and how great He is, [God] is invisible and indescribable to all things which have been made by Him, but He is by no means unknown: for all things learn through His Word that there is one God the Father, who contains all things, and who grants existence to all, as is written in the Gospel: “No man hath seen God at any time, except the only-begotten Son, who is in the bosom of the Father; He has declared [Him].” ^[22]

7. Therefore the Son of the Father declares [Him] from the beginning, inasmuch as He was with the Father from the beginning, who did also show to the human race prophetic visions, and diversities of gifts, and His own ministrations, and the glory of the Father, in regular order and connection, at the fitting time for the benefit [of mankind]. For where there is a regular succession, there is also fixedness; and where fixedness, there suitability to the period; and where suitability, there also utility. And for this reason did the Word become the dispenser of the paternal grace for the benefit of men, for whom He made such great dispensations, revealing God indeed to men, but presenting man to God, and preserving at the same time the invisibility of the Father, lest man should at any time become a despiser of God, and that he should always possess something towards which he might advance; but, on the other hand, revealing God to men through many dispensations, lest man, falling away from God altogether, should cease to exist. For the glory of God is a living man; and the life of man consists in beholding God. For if the manifestation of God which is made by means of the creation, affords life to all living in the earth, much more does that revelation of the Father which comes through the Word, give life to those who see God.

8. Inasmuch, then, as the Spirit of God pointed out by the prophets things to come, forming and adapting us beforehand for the purpose of our being made subject to God, but it was still a future thing that man, through the good pleasure of the Holy Spirit, should see [God], it necessarily behoved those through whose instrumentality future things were announced, to see God, whom they intimated as to be seen by men; in order that God, and the Son of God, and the Son, and the Father, should not only be prophetically announced, but that He should also be seen by all His members who are sanctified and instructed in the things of God, that man might be disciplined beforehand and previously exercised for a reception into that glory which shall afterwards be revealed in those who love God. For the prophets used not to prophesy in word alone, but in visions also, and in their mode of life, and in the actions which they performed, according to the suggestions of the Spirit. After this invisible manner, therefore, did they see God, as also Esaias says, “I have seen with mine eyes the King, the Lord of hosts,” ^[23] pointing out that man should behold God with his eyes, and hear His voice. In this manner, therefore, did they also see the Son of God as a man conversant with men, while they prophesied what was to happen, saying that He who was not come as yet was present proclaiming also the impassible as subject to suffering, and declaring that He who was then in
