That the Son, however, may be proved to be eternal as the Father is, it is declared more plainly in the hundred and eighteenth psalm (verse 89): 'For ever, O Lord,' he says, 'thy word standeth firm in heaven.' And in Isaiah: 'All flesh is grass, and all the glory of man as the flower of grass: the grass is withered and we, but the word of the Lord endureth for ever' (Isaiah XL, 6). Likewise there: 'I am the first, and I am unto eternity; my hand hath founded the earth, and my right hand hath made firm the heaven' (Isaiah XLVIII, 12). And so the Son is found neither unlike to the Father in eternity, nor proved inferior in power:
since those who are one in Godhead and in power cannot be distinguished in eternity; nor indeed does the Son lack the eternity of nature, who is taught to possess in himself all the fullness of the Godhead. CHAPTER LXIV. Where they say that the Father made the Son, but the Son made all things. If they shall say, the Father made the Son, but the Son made all things. Reply. In the nature of the Godhead, in which the Father and the Son are one, we never read that the Son was made by the Father, but begotten. For if in that he is the Word of the Father you assert that the Son was made, then by no means will God the Father have the perfection of his substance in himself, who could not have in himself the perfect Word, perpetually abiding, before the birth of his Son.
But we who believe the Son to be born of the Father ineffably and without beginning, vindicating the unity of the faith, neither yield to your unbelief by resisting, nor are overcome by craftiness, so as to deny in the Son the truth of the paternal generation—whose generation neither the Father himself who begat passed over in silence, nor did the Son himself who was born of the Father keep silent in his own preaching, as he says: 'For God so loved this world that he gave his only-begotten Son for it' (John III, 16). And again: 'The only-begotten Son, who is in the bosom of the Father, he hath declared him' (John I, 18). And the Lord himself says to the Jews: 'You are indignant with me, because I said to you, I am the Son of God' (John VII, 23 [X, 36]). And again:
'I came forth from the Father, and am come into this good world' (John XVI, 28). And David in the person of God the Father sings in the Psalms, and says: 'My heart hath uttered a good word' (Psalm XLIV, 2). Likewise the same: 'In the brightness of the saints, from the womb before the day-star I begot thee' (Psalm CIX, 3). Likewise the same concerning the Son: 'The Lord said to me, Thou art my Son, this day have I begotten thee' (Psalm II, 7). And in the Gospel, while the same Son was being baptized in the Jordan, the voice of the Father thundered, saying: 'This is my most beloved Son, in whom I am well pleased' (Luke III, 22). And on the mountain to the three disciples: 'This is my most beloved Son, hear ye him' (Matthew XVII, 5).
Hear the Father testifying with his own voice that he begot him of himself; hear the Son demonstrating the origin of his nativity, whence and from whom he is by that unutterable birth. Cease to call the Maker of the heavens and of the world and of all creatures a thing made. CHAPTER LXV. Where they say: As the Father hath life in himself, so also he hath given to the Son to have life in himself. If they shall object to you that the Son said: 'As the Father hath life in himself, so he hath given to the Son to have life in himself' (John V, 26). Reply. If the Son, abiding in the Father before the beginning of the world, had not life, how is he called the author of life, and proved to be life eternal? 'You demanded,' says Peter the apostle, 'a man that was a murderer to be granted unto you, but',
'you killed the author of life, hanging him on a tree' (Acts III, 14). And John the apostle: 'This is the true God, and life eternal' (1 John V, 20). And the Lord himself to Martha: 'I am the resurrection and the life' (John XI, 25). Likewise there: 'I am the bread of life, who came down from heaven' (John VI, 51). And to the Father: 'As thou hast loved me, I also have loved them' (John XV, 9). And: 'I give them life everlasting' (John X, 28). And again: 'I am come that they may have life.' For just as in the appellation of this name life cannot be divided from life, so the Son cannot be separated from the Father in the substance of the divinity: for the Father gave the Son not another life than that which abides in himself; but the very life that he has, that he gave;
and as great as the life that is in him, so great did he give; and in this very thing, that he gave life to the Son, he did not lose it. CHAPTER LXVI. Where they say that the Father alone dwells in inaccessible light. If they shall object to you that it is said of the Father alone, 'who alone hath immortality, and inhabiteth light inaccessible' (1 Tim. VI, 16). Reply. Not the Father alone without the Son inhabits inaccessible light, because where the Father is, there too the Son must be believed to be by undoubting faith. For if the Father alone without the Son—which it is wickedness to say—inhabits inaccessible light, it is necessary that the Father have an abode set apart from the Son: and if it be so, in what way could the Son himself, standing at the right hand of the Father, be beheld by the blessed martyr Stephen (Acts
VII, 56), if the Father, according to you, is said to be contained in other seats? Far be this from the understanding of the faithful, who cleave to Christ in the unity of the faith! For just as it is not in the Son when the Father alone is said to inhabit inaccessible light, so it does not suffice for the Father, when Wisdom, which is the Son, is said to traverse the circuit of heaven alone (Eccli. XXIV, 8). Therefore, since he is invisible and unbegotten, that he was seen in the Son is proved by the testimony of the Apostle, and that he abode and rested in the Son, begotten of himself ineffably, is shown, the Son himself saying in the prophet: 'He that created me rested in my tabernacle' (Eccli. XXIV, 12). And in the Gospel: 'The Father, abiding in me, doth these works' (John XIV, 10). And:
'No man hath seen God at any time, save the only-begotten Son, who is in the bosom of the Father' (John I, 18). The Son was in the bosom of the Father from the beginning, and the good word was uttered forth from the heart of the Father; how is he not to be believed to have inhabited inaccessible light, abiding with him in the paternal heart? Could the Father in any way dwell together in the Son without any light, or rest in the tabernacle of the Son without that same light, since the same Son is the brightness of eternal light, and the spotless mirror of the Godhead (Wisdom VII, 26), whom Solomon said he loved above his own health: in whose beauty he ever longed to delight?
'Above health and beauty,' he says, 'I loved her, and I purposed to have her for a light, because her light cannot be extinguished' (ibid., 10). This light therefore the prophet David, longing for it, anxiously cries out, saying these things: 'Send forth thy light and thy truth' (Psalm XLII, 5). And again: 'In thy light we shall see light' (Psalm XXXV, 10). In the brightness of this light therefore the Son showed himself beforehand to the three disciples on the mountain, and they, terrified with the fear of death, prostrate on their faces, perceived that the end of their life was at hand. This light, I say, displaying it in himself, the Son proclaimed, while he forewarned his disciples that they should walk in the same: 'While you have the light,' he says, 'walk in the light' (John XII, 35). And again:
'I am the light of this world; he that followeth me walketh not in darkness, but shall have the light of life eternal' (John VIII, 12). And the Evangelist: 'He was the true light,' he says, 'which enlighteneth every man that cometh into this world' (John I, 9). If this light, which is promised to believers, is proved to be in the Son, and is said to be eternal with the Eternal, how is the Son separated by you from the inaccessible light of the Father? For if the Son is true God and life eternal, without doubt he must be believed to dwell in this light together with the Father, which no one established in this mortal body can in any wise behold; but when he shall appear, then truly he shall see it as it is, whoever shall be made worthy to be joined to his sight:
and not as Moses and the rest of the prophets through riddles and figure, but he shall behold according to the Apostle the very substance of the Godhead truly in the Son. For if you are willing to investigate this same matter with a serene gaze of the mind, following the testimony of the prophet, you will find that the Son did not declare himself to be utterly separated from this light of the Father, since when he said that the Son alone conversed on earth with men, he did not make the Father alien from him. CHAPTER LXVII. Where they say that the Son is not perfect as the Father is. If they shall say that the prophet could say concerning the Son: 'Thine eyes did see my imperfect being, and in thy book shall all be written' (Psalm CXXXVIII, 15). Reply.
If, as the Apostle said, you would use the law of Christ lawfully, you would surely acknowledge that the Son is established by the divine Scriptures as both prince and perfect, the Apostle Paul attesting: 'In the days of his flesh,' he says, 'offering up prayers and supplications with a strong cry and tears to him that was able to save him from death, he was heard for his reverence; and being made manifest the Son, he learned obedience by the things which he suffered, who being made perfect became to all that obey him the author of eternal salvation, and was called by God a prince of priests' (Hebrews V, 7). Likewise there: 'For the word of the oath, which is after the law, the Son perfect for evermore' (Hebrews VII, 28). Likewise there:
'Having therefore a prince of priests who hath penetrated the heavens, Jesus the Son of God' (Hebrews IV, 14). Likewise there: 'Let us run to the prize of the contest set before us, looking unto the prince and perfecter, Jesus' (Hebrews XII, 2). And again: 'Until we all meet in the unity of faith and the acknowledgment of the Son of God, unto a perfect man, unto the measure of the age of the fullness of Christ' (Ephesians IV, 13). Recount, I pray, those things which are set above concerning the perfection and the princedom of the Son, and contrive no further your vanity craftily unto your own destruction. CHAPTER LXVIII. Where they say: As the living Father hath sent me, so I live by the Father. But if they shall say that the Son is lesser than the Father in this, that he himself said:
'As the living Father hath sent me, and I live by the Father.' Reply. This matter does not indicate any inequality of the Son, but demonstrates the full substance of the divinity in him, in that the Son subsists not from himself, nor out of nothing, but from the Father, which is the highest and singular mark of unity: for to live, in the case of the Father, what else is it but to be? and for the Son to live by the Father, what else is it but to subsist in the Father? 'Therefore as the living Father hath sent me,' he says, 'and I live by the Father' (John VI, 57): he could surely have said, 'And I live through the Father,' if he had wished to show in himself any difference of an inferior power, since he who lives through another can by no means live through himself;
but he who lives for the sake of another, he rather exists as the cause of the one living. For just as through the mission of the living Father the Son became known to the world, so through the living Son the name of the Father became known to the world and to men, while he proved that he himself lives not for the sake of the Father, by saying: 'I have made known to them thy name, and will make it known; and I have manifested thy name to men' (John XVII, 6). For those who in revealing each other are equal cannot indeed be unequal in power. CHAPTER LXIX. Where they say that in the Son the Father was compounded. If they shall say to you: If God is in God, that is, the Father in the Son, then the one was compounded in the other. Reply. We too therefore believe in the Son, because the Father is in him, since he himself says:
'The Father is in me, and I in the Father' (John X, 38). Likewise we believe the apostle Paul preaching this, because he said: 'God was in Christ, reconciling the world to himself' (II Cor. V, 19). Therefore we lend a Christian ear to the prophet Isaiah, because he began to preach the mystery as of those inseparably united, while he asserted that in the Son the Father was always one God, declaring beforehand that besides him there is no other: 'In thee is God,' he says, 'and we knew it not: for thou art the God of the ages, the Saviour' (Isaiah XLV, 14). To the prophecy of Solomon also we therefore believe without hesitation, since by his announcement we recognise that the unbegotten God rested in the tabernacle of the only-begotten Son: 'He that begot me,' he says, 'rested in my tabernacle' (Eccli. XXIV, 12).
God therefore, who is of a simple nature, is not compounded in another, because according to the substance of the nature of the Godhead, there is one God in the Son, in whom, even though two persons and names are designated, yet there is one virtue of the divine name in them; since those who by nature are one cannot be diverse in divinity. CHAPTER LXX. Where they say: the Father of whom are all things, and the Son through whom are all things. But if they shall say: If the Father and the Son are one, how is the Father one, of whom are all things, and the Son another, through whom are all things? Reply.
Drive out at last from your senses those things which the Arian heresy, straying from the way of truth, instils into you, and learn that just as of the Son, so also of the Father holy Scripture records it spoken, since just as through the Son all things, so through the Father all things are believed to have been perfected. But if you judge the Son to be lesser than the Father on this account, because the Apostle said: 'One God the Father, of whom are all things, and one Lord Jesus Christ, through whom are all things' (1 Cor. VIII, 6), you ought diligently to attend to all the things that were said by the Apostle: and you will find that the Father too is not alien from the designation of this work, the same Apostle affirming: 'Brethren,' he says, 'God, through whom you are called into the one hope of your calling' (Ephesians IV, 4). And again:
'For of him, and through him, and in him are all things' (Rom. XI, 36). Of whom do you suppose this was said? answer, I pray: If the Apostle says these things of the Father, observe that of him, and through him, and in him are all things. But if of the Son, in like manner also you ought to attend, that of him, and through him, and in him are all things. By whatever argument you shall wish to assail the unity of the Father and the Son, you will appear to lie subject to the verdicts of your own words. CHAPTER LXXI. Where they say: If the Father and the Son are one God, then first the Word, and afterwards God. If they shall say to you: If the Father and the Son are one, then first he was the Word, and afterwards he was called God, because it is written:
'In the beginning was the Word, and the Word was with God, and the Word was God' (John I, 1). Reply. If according to a difference of common nature the Father and the Son are not called one God, then two gods, unlike in nature and unequal in power, are worshipped by you after the manner of the heathen, against that which is said: 'Hear, O Israel, the Lord thy God is one God' (Deut. VI, 4). We therefore confess in the profession of our faith neither the Word before God, nor God before the Word, but both together one God: because no intervals of time distinguish the Father and the Son from each other; and where neither time, nor any moment of time is found, so neither is there found a before or after—which it is wickedness to say.
We also call the only Son of God not only the Word, but also the splendour and the power of the Father, and Wisdom, according to the words of the divine Scriptures. And it is sacrilege to say that the Father was ever light without splendour, or strong without power, or wisdom without his own wisdom, whose perfect divinity has assumed nothing for its perfection from accidental things, whom the rational universe by believing recognises to contain in himself the things that are his own. But that the Evangelist wished to use first of all the appellation of the Word, he the more evidently declared the unity of the divinity, naming the Son before the Father, assigning no relation of time or of honour:
since where the Word is narrated to have been with God, and God to have been the Word, neither is God set before the Word, nor the Word before God. CHAPTER LXXII. Where they say: If the Father and the Son are one God, then first God, and afterwards he was called Father. If they shall say to you: If the Father and the Son are one God, then first he was God, and afterwards by begetting he was called Father. Reply. If therefore, according to you, he first subsisted singularly as God, and afterwards was called Father by begetting the Son, then the very name of Father will by no means be eternal, which took its beginning for him in time as the title of its appellation.
If according to you it is thus, he is mutable and will make progress, and will thereafter be mutable, because from the name of God he passed over into the appellation of Father. Making progress therefore, because, when he saw himself placed in the name of God to be less perfect, he added to himself, in the manner of those who complete, the name of Father unto the sum of his perfection. But who does not see that for this reason you used in this place that testimony of the Apostle, where he said: 'God and Father of our Lord Jesus Christ knoweth' (II Cor. XI, 31), so that thence you wished to show the dignity of God to precede the affection of Father? And although we remember that very many things have already been said above concerning what you have now wished to repeat, it seems superfluous to repeat again those things which, once said, could profit the instruction of readers.
But lest you accuse us of inexperience in having declined the propositions, it behoves you to know that the same apostle, writing to the Ephesians, named the Son and the Father first, and afterwards added the appellation of his deity: 'Giving thanks,' he says, 'always for all things in the name of our Lord Jesus Christ, to the Father and God, being subject one to another in the fear of Christ' (Ephesians V, 20). Since therefore you see the Apostle using sometimes first the appellation of God, sometimes of the Father, he most clearly teaches that the title of the divine and paternal name was everlasting, and that the Son is co-everlasting with the everlasting Father, and abides perpetually with the same. CHAPTER LXXIII. Where they say:
The Son and the Father is not called one God, who before the ages was born of the Father, and afterwards born of the Virgin. If they shall say to you: How shall he who before the ages was born of the Father, and afterwards born of the Virgin, be one God with the everlasting and unbegotten Father? Reply. The nature of the Word is one thing—who, abiding impassible, is shaken by no fear of sorrow—and another is the soul of our kind, which the Son deigned to take from us, that is, from a mother, in order to show himself a perfect man, by taking a man upon himself. Of which also he said: 'My soul is sorrowful even unto death' (Matthew XXVI, 38). And therefore a twofold, that is, a divine and human, nativity
did not prove the Son to be diverse from the Father, since in that birth from the substance of the paternal nature he remained as great as he is, and in this by which he was afterwards brought forth from the Virgin he did not change, as he himself testifies in the Gospel: 'I and the Father are one' (John X, 30); and, 'That they may be one in us, as we are, thou in me, and I in thee' (John XVII, 21). For that which he said: 'I have power to lay down my soul, and I have power to take it up again' (John X, 18), agrees in every way with his divinity, since no place is found apart from his divinity where his soul might be laid down by him, or whence it might be taken up.
We do not confess that the Father is the Unbegotten and the Son also unbegotten; for if the Son were called unbegotten just as the Father is unbegotten, then they could no longer be one, since each, standing fast in his own proper nature, would have no communion of substance with the other. THAT THE HOLY SPIRIT IS ONE GOD WITH THE FATHER. CHAPTER ONE. Where they say that the Father, the Son, and the Holy Spirit are not one God because they are distinguished by their own proper names. If they say to you: The Father and the Son and the Holy Spirit are not one for this reason, that they are distinguished by their own proper names. Reply. If, because the Father is called God, and the Son Jesus Christ, and the Holy Spirit the Paraclete, they cannot for that reason be one:
then it is not left to the Son or to the Holy Spirit to be named by the title of deity. If this be so, where then is that which the Apostle said of the Son: 'Whose are the fathers, and of whom is Christ according to the flesh, who is over all things, God blessed for ever' (Rom. 9:5)? Or why did Jeremiah give Him such testimony as to say that He is God, conversing on earth with men? 'This is our God,' he says, 'and no other shall be accounted beside him' (Baruch 3:36). And a little after he said: 'After this he was seen upon earth, and conversed with men' (ibid. 38). And again the Apostle says: 'Looking for the blessed hope, and the coming of the glory of the great God, our Saviour Jesus Christ' (Tit. 2:13).
If, then, the Father is called God, and the Son is named by the same title, how is the name of the Father and the Son not one name, since they are not divided from one another in the very appellation of deity? For the Holy Spirit is shown not to be a stranger to this title of deity, since by the Apostle the same Holy Spirit is called God and Lord: 'God is a Spirit,' he says (John 4:24). And the Son in the Gospel said: 'That which is born of the flesh is flesh, because it is born of flesh; and that which is born of the Spirit is spirit, because God is Spirit' (John 3:6).
In vain, therefore, did you wish to parcel out the names common to each Person by some special distribution, since by the inseparable manner of appellation the heralds of the supernal powers also fittingly bear witness together to the sacred Trinity. CHAPTER II. Where it is said: 'When I am gone, I will send you the Paraclete.' If they say to you concerning the person of the Holy Spirit, that the Lord, the Son of God, Himself said: 'When I am gone, I will send you the Paraclete, the Spirit of truth, and he himself shall teach you all truth' (John 15:26; 16:13). Reply. The very divine order of the words ought to have taught you what you, blinded by the error of unbelief, are not permitted to behold with the clear attention of mind:
namely, what so loving and so fitting a help for the human race could the Godhead provide, than that He who foretold Himself to be the Truth should also by His own proclamation mark out the Holy Spirit as being the Truth? So that, if (according to you) He had not been the Truth, or possessed a substance inferior to the Son, then surely when He came He would not teach the disciples all truth. But because there is one deity and power in both, therefore the things which the Son teaches, those same the Spirit also is known to teach; and in this the Holy Spirit cannot be called or said to be inferior to the Son: for just as the Son sent the Spirit to the disciples, so He foretold by prophetic announcement that He Himself was sent by the Holy Spirit, Isaiah himself speaking:
'The Spirit of the Lord is upon me, because he hath anointed me; he hath sent me to preach the gospel to the poor, to proclaim release to the captives, and sight to the blind' (Isa. 61:1), and so forth. And the Evangelist thus announces concerning Him: 'But Jesus himself said: He returned in the power of the Spirit into Galilee' (Luke 4:14). He who, returning in the Spirit, was performing works of power, cannot proclaim the Holy Spirit to have been inferior to Himself. CHAPTER III. Where it is said: 'I am the Lord, establishing the thunder, and creating the spirit (wind).' If they bring against you the prophetic testimony in which it is said: 'I am the Lord, establishing the thunder, and creating the spirit' (Amos 4:13). Reply.
The prophet, in saying this, does not show the Holy Spirit to be a creature, but rather the wind, which often arises in the disturbance of the air, and which the lightnings and thunders are proved to precede, as Jeremiah says: 'The wind blows in every region in the clouds; and when it is commanded to traverse the whole world, it accomplishes what is commanded; the lightnings also sent down from above, that they may consume cities and forests, do what is commanded' (Baruch 6:60). But these neither in appearance nor in power resemble that One; whence neither is it to be supposed nor said that they are gods, since they can neither pronounce judgment nor do good to men, because they are not gods. And in Ezekiel: 'Thus saith the Lord:
I will bring up a wind lifting itself in my wrath; in the consummation you shall perish, you and that which you have anointed; its foundations shall be revealed, and they shall fall' (Ezek. 13:13). And Jonah the prophet: 'And the Lord raised up a wind in the sea, and there was a great tempest in the sea, so that the ship was in danger of being covered by the waves' (Jonah 1:4). Likewise there: 'And it came to pass on the morrow, when the sun was rising, that God commanded a burning wind, and the sun beat upon the head of Jonah, and he fainted with heat' (Jonah 4:8). Likewise in the Psalms: 'With a violent wind thou shalt break the ships of Tharsis' (Ps. 47:8). Likewise there: 'He shall rain snares upon sinners; fire and brimstone and a stormy wind shall be the portion of their cup' (Ps. 10:7). Likewise there:
'He raised up a stormy wind, and its waves were lifted on high' (Ps. 106:25). Likewise there: 'Fire, hail, snow, ice, stormy wind, which fulfil his word' (Ps. 148:8). For that the Holy Spirit is Creator and not creature, as you allege, is taught in this manner, the prophet David saying: 'Thou shalt take away their spirit, and they shall fail; thou shalt send forth thy Spirit, and they shall be created' (Ps. 103:29). Likewise he himself: 'By the word of the Lord the heavens were established, and all their power by the Spirit of his mouth' (Ps. 32:6). And in the book of the discourses of Job: 'It is the divine Spirit that made me' (Job 33:4). And in the canticle of Judith:
'Let all thy creation serve thee, for thou didst speak and they were made; thou didst send forth thy Spirit, and they were built up' (Judith 16:17). And in Solomon: 'And he saw, and numbered, and measured all things; and he himself created them through the Holy Spirit, who is the Creator and the maker of his own work' (Sir. 1:9) — that is to say, the creature made by Him cannot be compared with Him, nor even be judged similar to Him. CHAPTER IV. Where they say that the Holy Spirit was made subject to the prophets. If they say to you that which is written: 'The spirits of the prophets are subject to the prophets' (1 Cor. 14:32). Reply. The spirit of the prophets is subjected to the Holy Spirit, but not the Holy Spirit, by whose inundation the spirit of the prophets spoke, as David sings in the Psalms:
