And how do you confess the Son to be of His substance, when the Son has often been seen by the patriarchs as changeable and mutable, and often shown forth to each in various forms? For if He were of that very substance, He would surely not be discerned as visible even by the assumption of flesh, but rather He would have remained in that equality in which the Father is, from whose substance He was; because what is of the Father must be believed unable to be seen, or changed, or altered. ATHANASIUS: This is the cause of error, this the origin of the Arian heresy, that they do not understand the power of God, nor do they recognize the dispensation of so great a mystery. To these it must first be answered that the Son of God was seen not as He was as God, but as man was able to apprehend Him.
Next, that it belongs to the power of God that, when He deigned to be revealed to individuals as He willed, He changed His appearance but did not alter His substance; nor, losing the property of His quality, but according to the merit of the beholder He applied a tempering to His majesty. Yet He Himself, as He is ever the same, remained in the property of His own substance, as it is written: 'Thou shalt change them, and they shall be changed; but thou art the selfsame, and thy years shall not fail' (Ps. 101:28). For the angels also, though often seen in the form of men, are nevertheless nothing other than what they know themselves to be, nor do they change their substance when they take on the form of a human body. How much more shall the Author of the angels not be changed, who by His own bounty granted the angels that they might be able to do this?
You see, then, the dispositions of things to come, which were to be fulfilled each in its own time, foreshown to the patriarchs in Him through an image, yet not God Himself seen as He properly is. THE HERETIC: I do not understand what you will say concerning the incarnation, and by what reasoning you will excuse its mutability. For we read: 'The Word was made flesh' (John 1:14). Then surely He filled the Virgin's womb; then was born something other than what had come. Whence now, the substance having been mingled, He changed His state, He loses His order in that very change: from God He was made man, from spirit, flesh. And every transference is certainly the interruption of a former state.

Therefore there is no doubt that the Son must be believed to be of another substance, which can be altered, and changed, and seen; because it is not lawful to believe this of the Father's substance, since He says: 'I am; I am, and I change not' (Mal. 3:6). And the Son in the Gospel: 'No man hath seen God at any time' (John 1:18). ATHANASIUS: Mingling indeed, or coalescence, is a change of nature; a change of nature produces a transference; and transference destroys what it was, and begins to be what it was not. The nativity of Christ does not have this, as the angel Gabriel testifies, who, when questioned about the possibility of Mary's conceiving, the Evangelist relates answered: 'The Holy Spirit shall come upon thee, and the power of the Most High shall overshadow thee' (Luke 1:35).
Who, in neither saying, named a mingling, but the coming upon of the Holy Spirit, and the overshadowing of the Most High. You read, 'The Word was made flesh' (John 1:14). But how it was made, our mind certainly does not reach; because what we believe surpasses our mind: but we attain it by faith. And thus in this way we hold the whole by faith, what we believe, even though we do not comprehend the whole with the mind. We ought therefore to know what and how much it is granted us to attain by understanding, and what to receive by faith; for we read: 'No man hath ascended into heaven, but he that descended from heaven, the Son of man who is in heaven' (John 3:13). How was the Son of man, who was speaking on earth, said to be in heaven?
And how is He said to have descended from there, who was neither made there, nor had yet ascended? Because, not yet having suffered, He had not risen. But because God the Word, about to take up manhood, had descended, the man, joined to the Godhead, ascended thither whence the flesh certainly had not descended, but the Word. Moreover, we read of the Lord speaking to John in the Apocalypse: 'I am the first and the last, and I was living and was dead, and behold I am living for ever and ever' (Rev. 1:17). If the first, how the last? If living, since He Himself is the life of all, how dead, since life cannot die? But if dead, how is He to be called either God, or life? And surely whoever has excluded any portion of the truth will not hold the perfect truth.
But you who object against the incarnation of your Creator and Redeemer, first investigate, if you can, the reason of your own birth. Surely you will admit that man subsists of two substances, soul and flesh; and yet he is called not two, but one man. And although his nature is united, the substances nevertheless remain unmixable. If, then, in man, joined together by God, the substances remain unmixable, consider what you are forced to think of the incarnation of your Creator, who indeed by His condescension is mingled with man, yet not commingled:
and the Word was so made flesh, that is, the only-begotten Son of God was so made the son of man, that neither being turned into the other, but each remaining in its own substance, God in man so suffered human things that in Himself He kept the divine things entire; not that by any conversion or mutability He began to be what He was not, but that by the power of the divine dispensation the Word of the Father, never departing from the Father, deigned properly to become man, and the only-begotten was made incarnate by that secret mystery which He Himself knows; for it is ours to believe, His to know. And thus God the Word Himself, taking up into Himself the whole of what belongs to man, is man; and the man assumed, by receiving the whole of what belongs to God, cannot be other than God.
Therefore no conjecture is to be made from visible things, as if we should suppose God and man to be commingled like creatures equal to one another, and that by such a confusion of flesh and Word some single body was produced. Far be it to believe thus; for such a mingling is a corruption of both parts. For God is one who contains, not one who is contained; one who penetrates, not one who is penetrated; one who fills, not one who is filled; who is everywhere whole at once, and everywhere diffused. By the infusion of His power He condescendingly was united to human nature, not that the human nature was mixed into the divine nature. The flesh therefore advanced into the Word, not the Word into the flesh. Most truly, then, the Word was made flesh:
but, as we have said, of Him alone properly and personally, not together with the Father or the Holy Spirit by nature; because the only-begotten Son of God, true God, who with the Father and the Holy Spirit is one in nature, is another in person. For we do not say that the Father Himself is the same as the Son; nor again do we say that the same Son is the same as the Father; nor again do we call the Holy Spirit the Father or the Son; but distinguishing the persons in their properties, we name God the Father, the Father properly; and the Son God, we call the Son properly; and the Holy Spirit God, we confess the Holy Spirit properly. And when we say 'God' three times in number, we do not believe three gods, but one perfect God in the Trinity of His omnipotence.
Therefore one person is to be received, of the flesh and of the Word: one and the same God and man, ever inseparable and of twofold substance, truly and ever to have done all things that belong to man, and truly and ever to have possessed those things that are God's: 'For although He was crucified through our weakness, yet He liveth by the power of God' (2 Cor. 13:4). Wherefore we are not afraid to say that God was born according to the man, and that the same, according to the man, was a God who suffered, a God who died; but we glory to say that God was born, and that the same, according to the man, suffered. Who, when He was in the form of God, took the form of a servant not for His own sake but for ours, and emptied Himself. How did He empty Himself? In that, being the form of God, He took the form of a servant:
in that, being principally Lord, He condescendingly assumes those things which belong to a servant; and in that, through His indulgence and compassion toward us, by bearing or doing lower things, the Word made flesh is, as it were, emptied in person of what He possessed in nature. And in the Word, by the habit of humanity, being obedient as man, He restored in Himself, through the humility and obedience of our nature, that which had perished in Adam through disobedience. And dead in the flesh, He who ever lives in the Spirit, giving life with the Father to all things, henceforth never to die again.
He is raised up by the Father in the flesh, and becomes for us the firstborn from the dead, He who is the only-begotten of the living God, and through the various ages for our sake poor in time, needy in His manhood, receives for us what He, abounding, ever had for Himself in the Father. THE HERETIC: Be assured that the foregoing things, established in my heart, have been set forth reasonably and truly; but for the fullness of faith I beg you to expound why they are divided by persons and names, since the substance of the Father, and of the Son, and of the Holy Spirit is one. ATHANASIUS: Are you ignorant that the Father is one God, and the Son is one God, and the Holy Spirit is one God? The name is one, because their substance is one. Whence John also in his Epistle says:
'There are three who bear witness in heaven, the Father, the Word, and the Spirit; and in Christ Jesus they are one' (1 John 5:7); yet He is not one person, because there is not one person of them. Surely nothing else is to be thought than that the one true Father who begot is not Himself also the one who is begotten of Him; and that the one Son who did not beget is not the Father; and that the Holy Spirit, who is neither Father nor Son, is another in person, who moreover is reported neither to have begotten nor to have been born. THE HERETIC: Why do you name them distinctively? ATHANASIUS: Without doubt the Father truly begot; this is His first name. The Son indeed was born of Him; this is His unique name. But the Holy Spirit, who proceeded from the Father, this is His natural name.
While, therefore, the names are distinguished in the persons, the proper names are displayed; while it is referred to according to the deity, the one united name is indicated in them; because the Father is substantive, the Son is substantive, and the Holy Spirit is substantive. Let there be in us, then, according to the confession of saving baptism, an entire faith of the Trinity; let there be one devotion of piety; nor, after the manner of the Gentiles, let us imagine diversities of powers, but rather, adoring and magnifying the perfect Trinity, as we say in the mysteries with our mouth, so let us hold it in our conscience: 'Holy, holy, holy, the Lord God Almighty' (Isa. 6:3). Saying 'holy' three times, you confess one omnipotence. Or that saying of the Apostle: 'One Spirit' (Eph. 4:4).
'The Lord Jesus Christ in the glory of God the Father' (Phil. 2:11). One Amen, because there is one religion, one glorification of the Trinity. And thereafter, pursuing peace and love, let us ever abound in new works, that we may hear from the Apostle: 'The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Spirit be with you all. Amen' (2 Cor. 13:13). THE ARIAN PROFESSION, AND THE CATHOLIC CONFESSION OF SAINT ATHANASIUS. TO THEOPHILUS. The Arians say that the Son of God was not begotten of the substance of God the Father, but created from without. I believe that the Son of God was born of the Father's substance, not created, just as also the Holy Spirit the Paraclete, who is the Son's, proceeds from the Father. And therefore I say 'Homousion'; with the Father saying to the Son:
'With thee is the principality in the day of thy power, in the splendours of the saints; from the womb before the day-star I begot thee' (Ps. 109:3). Likewise the Son also attesting: 'The Lord said to me: Thou art my Son, this day have I begotten thee' (Ps. 2:7). For also, at the time of the passion, when Pilate inquired of Him, the Jews accusing Him, whether He was a king, the Lord answering said: 'For this was I born' (John 18:37). Concerning the Holy Spirit also the Lord says: 'The Holy Spirit who proceedeth from my Father' (John 15:26). It is established, therefore, that according to the one substance of the deity the Son is begotten of the Father, not created; and the Holy Spirit proceeding from the Father, and being wholly of the Son, just as a fountain is from a fountain, and light from light.
The Arians say that the Son, or the Holy Spirit, was not always with the Father, or in the presence of the Father. I believe that the Son of God, according to the divine Scriptures, is the Word, the power, and the wisdom of the Father. And by faith I confess that His Son was never lacking to the Father, because the name of fatherhood was never lacking to Him, so that the Father is never to be believed to have been without wisdom, without the Word, without His own power, according to the preaching of the Evangelist John, who says: 'In the beginning was the Word, and the Word was with God, and the Word was God; the same was in the beginning with God. All things were made by Him' (John 1:1). He says all things were made by Him, not that He was made. So neither was the Father, nor the Son, ever without the Holy Spirit.
The Arians say that the Son has no power, except what He has received from the Father. Likewise concerning the Holy Spirit, except what He has received from the Son. I believe that, according to the divine substance, just as the Son is the Word, the power, the wisdom, the arm, the hand, so also He is the power of the Father. For according to the sentence of the Lord Himself: 'Whatsoever things the Father doeth, these same the Son also doeth in like manner. And as the Father raiseth up the dead and giveth life, so the Son also giveth life to whom He will' (John 5:19, 21). For He cleansed the leper not by another's command, but by His own power, saying: 'I will; be thou made clean' (Matt. 8:3).
So also the paralytic, among the Jews who were ignorant that He was the true God, when they said that none could forgive sins except God alone, He most manifestly declared Himself God, and showed forth His own power, saying: 'But that you may know that the Son of man hath power on earth to forgive sins,' He said to the paralytic: 'Arise, take up thy bed, and go into thy house' (Matt. 9:6). Likewise also He examines the faith of the blind men, saying: 'Believe ye that I am able to do this unto you?' (ibid. 28). When they had confessed that it was in His power, He brings the remedy of healing, saying: 'According to your faith be it done unto you' (ibid. 29). Concerning the passion also of His own body, indicating that it was in His own power, He thus says:
'No man taketh away my life from me: I have power to lay it down, and I have power to take it up again' (John 10:18). And countless other things. Concerning the power of the Holy Spirit also He Himself says: 'The Spirit breatheth where He will' (John 3:8). Surely, where by His own will and divinity He has willed to breathe, not where He has been commanded. As also the Apostle, preaching of the gifts of graces, teaches: 'But all these worketh one and the same Spirit, dividing to every one according as He will' (1 Cor. 12:11). For He also by His own power fills the prophets, and chooses and directs the apostles, and appoints bishops, as we read in the Acts of the Apostles. There are also countless other testimonies which it would now be long to expound;
and therefore, just as one substance, so I believe one power of the Father, and of the Son, and of the Holy Spirit. But what the Son received, He received according to the man, that is, according to the form of a servant, according to the nature of our condition, the Lord Himself saying in the Gospel: 'And He hath given Him power to do judgment, because He is the Son of man' (John 5:27). The Arians say that the whole Father cannot be apprehended by the Son, or beheld; just as neither does the Holy Spirit see or apprehend the whole Son. I believe that, just as the Son is in the Father, and is wholly seen by the Father, so also the Father is wholly seen by the Son, and is wholly in the Son; the Son Himself saying: 'I am in the Father, and the Father in me' (John 14:11). And:
'As the Father knoweth me, and I know the Father' (John 10:15). Likewise also concerning the Holy Spirit, the Apostle preaching that the Spirit searcheth even the deep things of God. And just as no man knoweth what is in a man, according to the sentence of the same Apostle, save the spirit of the man which is in the man; so also the things that are of God no man knoweth, but the Spirit who is in Him. For the Lord also in the Gospel says thus even of little ones: 'Because their angels always behold the face of the Father' (Matt. 18:10). It is impious to believe that the Son and the Holy Spirit do not wholly behold or apprehend the Father. The Arians say that there is only one God perfect, omnipotent, incomprehensible, unbegotten, unending; the Father alone, and immortal.
I believe, according to the divine Scriptures, in God and Lord the Father unbegotten, in God and Lord the Son begotten of the Father, in God and Lord the Holy Spirit proceeding from the Father and abiding in the Son. But the Son, just as in deity I do not call lesser, so in the form of a servant, which submitted to the passion, I confess to have been made less, the Apostle saying: 'But Him who was made a little lower than the angels, we see, namely Jesus, on account of the suffering of death' (Heb. 2:9). And therefore in three persons I do not perceive three gods, but I adore and worship one God and Lord in substance, divinity, power, equality, and perpetuity, as it is commanded in the law: 'Thou shalt adore the Lord thy God, and Him only shalt thou serve' (Deut. 6:13).
The Arians say that the Father alone is the invisible God, and the greater, and therefore alone to be worshipped and adored. I believe, according to the divine substance and majesty, that the Son is Spirit, and that the Holy Spirit also is Spirit, the Lord saying in the Gospel: 'God is a Spirit' (John 4:24). And therefore, as I have said, according to the divine substance I confess the Father invisible, the Son invisible, the Holy Spirit invisible; and I believe nothing greater nor lesser in the substance of the deity. Therefore I render the same honour to the Son and to the Holy Spirit which I render to the Father, the Lord commanding: 'That all may honour the Son, even as they honour the Father; for they who honour not the Son, honour not the Father' (John 5:23).
And concerning the Holy Spirit He Himself says: 'He who shall blaspheme against the Holy Spirit, it shall not be forgiven him, neither in this world nor in the world to come' (Matt. 12:32). Therefore, then, I believe one God in the Trinity, the divine Scripture teaching: 'Hear, O Israel, the Lord thy God is one God' (Deut. 6:4). The Arians say that the Son of God, according to the substance of His divinity, is both visible and lesser. I believe Him, in the form of God, as we have approved above, invisible, He Himself saying to Moses: 'No man shall see my face and live' (Exod. 33:20). But equal in all things to the Father, except in this, that the One is unbegotten and the Other begotten; the Apostle preaching of Him:
'Who, being in the form of God,' he says, 'thought it not robbery to be equal with God' (Phil. 2:6). The Arians say that the Son or the Holy Spirit is so exiled from the secrets of the Father, that He knows nothing of the secret dispositions except what is revealed by the Father, what He has willed to reveal to the Son; and to the Spirit, what has been made manifest by the Son. I believe the Son to be in the Father, and the Father in the Son, and the Holy Spirit also, the Paraclete, who proceeds from the Father, to be both the Son's and the Father's, because He also proceeds from the Son, as it is written also in the Gospel, that by His own breathing He gave to His disciples the Holy Spirit, saying: 'Receive ye the Holy Spirit. Whose sins ye shall forgive, they are forgiven them:'
'and whose sins ye shall retain, they are retained' (John 20:22-23). And therefore I confess the Trinity inseparable, nor do I say that the Son or the Holy Spirit is exiled from God the Father, as the heretics speak; since the Son, who is the wisdom of God the Father, is Himself also the will of the Father, which was ever in Him, and He Himself is the Angel of great counsel; and through Him were all things created (Isa. 9:6), as the apostle Paul preaches, which are in the heavens and which are on the earth, visible and invisible (Col. 1:16). And John the Evangelist teaches that all things were made through Him, and without Him was made nothing (John 1:3).
For just as the divine Scriptures declare that all things were made through Him, so also whatsoever the Son does, He testifies that He does together with the Father, saying: 'But the Father who abideth in me, He doeth the works' (John 14:10). By these things showing that the Father never disposed or made anything without the Son, who is the wisdom, the Word, the will, and the power of the Father, nor the Son without the Father. But concerning the Holy Spirit there is no doubt that He is ignorant of nothing, nor is He exiled from the Father; since to say that the Father was ever without His own Spirit is of the highest madness, because He Himself searcheth, according to the Apostle, as has often been said, the deep and high things of God (1 Cor. 2:10).
And that the same Spirit is the Son's, we have proved by many testimonies of the Scriptures; and that He wholly abides in the Son; and that, just as He proceeds from God the Father, so He proceeds from the Son, that the whole Trinity may be believed one God. There is nothing, therefore, which the Father makes or disposes without His own wisdom; nothing which He knows or disposes without His own Holy Spirit, of whom the prophet thus says: 'The Spirit the Paraclete, the Spirit of wisdom and understanding, the Spirit of counsel and might, the Spirit of knowledge and of piety' (Isa. 11:2); all of which consist in God, who is the Trinity. The Arians say that the Son of God was not in heaven with the Father at the time when He was dwelling among men.
I believe that God the Son of God, according to the power of His deity, was in heaven and on earth at the time of His incarnation, and fills all things, and was never absent, He Himself saying to Nicodemus in the Gospel: 'No man hath ascended into heaven, but he that descended from heaven, the Son of man, who is in heaven' (John 3:13). The Arians say that the Son of God existed when He was not, and before He was born He was not, and that He was made out of things that did not exist. I believe one substance of the Father, and of the Son, and of the Holy Spirit. Therefore I confess that the Son, who is the wisdom of the Father, was ever in Him, and is begotten of Him; because there never was a time in which the Father is believed by the faithful to have been without His Word and wisdom:
nor did the Son ever exist at any time without His Father; the Evangelist saying, and repeating often, that in the beginning was the Word, and ever was, and was God, and was with God, nor made out of things that did not exist, but in the Father, and with the Father, God with God, ever was. The Holy Spirit also both was, and is ever in the Father, and proceeds from Him, nor was the Father ever without His own wisdom, who is the Son, never without His own Holy Spirit. The Arians say that the Son of God is passible, and in His own substance mortal. I believe God the Word, and the wisdom of the Father, because He is one with the Father, to be impassible and immortal in His own substance.
But I confess that the passible and mortal man Jesus Christ was assumed of the Virgin Mary, who was united to the Word of God; the same Lord saying: 'The spirit indeed is willing, but the flesh is weak' (Matt. 26:41). The same again saying: 'That which is born of flesh is flesh; and that which is born of the Spirit is spirit' (John 3:6). So also the Apostle preaches to the Corinthians, saying: 'For although He was crucified through our weakness, yet He liveth by the power of God' (2 Cor. 13:4). Crucified, therefore, through the weakness of our flesh, but He lives by His own power, because the Son of God is proved to be God and the power of the Father. For He Himself is the way, the truth, and the life (John 14:6).
I confess also that the same man Christ Jesus, after the passion, was raised up from the tomb on the third day without corruption by God the Word, by whom also He was assumed; He Himself saying to the Jews, according to the Evangelist John, concerning the temple of His body: 'Destroy this temple, and in three days I will raise it up' (John 2:19). The Arians say that there are three diverse substances, and unequal persons, of the Father, and of the Son, and of the Holy Spirit. I do not believe in diverse substances and unequal persons of the Father, and of the Son, and of the Holy Spirit, but I confess three perfect persons, equal, and eternal, of one substance, of one power, of one virtue and majesty; because what is diverse cannot be one:
and what is reckoned by degrees is not equal. I believe the Son of God, the Word of God, the power of God, and the wisdom of God, ever equal to the Father. For the Son would not say that He is one with the Father, nor that the Father is seen in Him and He in the Father, unless He knew Himself equal; nor would He do the same things as the Father, or profess what He Himself willed, nor would He preach that He had proceeded from the Father and come into the world, and again would leave the world and go to the Father, the Father also abiding in Himself, unless He knew Himself begotten of the substance of His Father. For in the Gospel of John, when the Jews sought to stone Him, He asserts, saying:
not only because He broke the sabbath, but because He said that He was the Son of God, making Himself equal to God (John 5:18). Therefore, that which is equal cannot be unequal: for the substance of the Father and of the Son is one, one power, one and undivided authority. Since no one, as He Himself says in the Gospel, snatches His own sheep from the hand of the Son, nor can anyone snatch the same from the hand of the Father. And what is one cannot be diverse. The same again saying, when He had already premised the one and the same power of Himself and of the Father, afterward He assigns the very unity of substance, saying: 'I and the Father are one' (John 10:30).
The Holy Spirit also is in nothing an unequal person, nor of a substance diverse from the Father and the Son, so that the same Holy Spirit Himself, proceeding from the Father, is also the Son's; nor was He ever lacking to the Father, just as neither to the Son; so that, just as without beginning He ever was, and at the creation of the world was with the Father and the Son, He also Himself confirmed all things and illuminated them: so also the sacrament of baptism is not fulfilled except under His invocation and power, just as not without the visitation of the Father and of the Son.
