Concerning whom was the controversy? Was it not concerning the Only-begotten God, the Maker of all the creation, whether He always was, or whether He came into being afterwards as an addition to His Father? What then do our master's words say on this matter? That it is irreverent to believe that what is naturally good was not in God: for that he saw no cause by which it was probable that the good was not always present with Him Who is good, either for lack of power or for weakness of will. What does he who contends against these statements say? "If you allow that God the Word is to be believed eternal, you must allow the same of the things that have been created"--(How well he knows how to distinguish in his argument the nature of the creatures and the majesty of God! How well he knows about each, what befits it, what he may piously think concerning God, what concerning the creation!)--"if the Maker," he says, "begins from the time of His making: for there is nothing else by which we can mark the beginning of things that have been made, if time does not define by its own interval the beginnings and the endings of the things that come into being."
On this ground he says that the Maker of time must commence His existence from a like beginning. Well, the creation has the ages for its beginning, but what beginning can you conceive of the Maker of the ages? If any one should say, "The beginning' which is mentioned in the Gospel"--it is the Father Who is there signified, and the confession of the Son together with Him is there pointed to, nor can it be that He Who is in the Father [891] , as the Lord says, can begin His being in Him from any particular point. And if any one speaks of another beginning besides this, let him tell us the name by which he marks this beginning, as none can be apprehended before the establishment of the ages. Such a statement, therefore, will not move us a whit from the orthodox conception concerning the Only-begotten, even if old women do applaud the proposition as a sound one. For we abide by what has been determined from the beginning, having our doctrine firmly based on truth, to wit, that all things which the orthodox doctrine assumes that we assert concerning the Only-begotten God have no kindred with the creation, but the marks which distinguish the Maker of all and His works are separated by a wide interval. If indeed the Son had in any other respect communion with the creation, we surely ought to say that He did not diverge from it even in the manner of His existence. But if the creation has no share in such things as are all those which we learn concerning the Son, we must surely of necessity say that in this matter also He has no communion with it. For the creation was not in the beginning, and was not with God, and was not, God, nor life, nor light, nor resurrection, nor the rest of the Divine names, as truth, righteousness, sanctification, Judge, just, Maker of all things, existing before the ages, for ever and ever; the creation is not the brightness of the glory, nor the express image of the Person, nor the likeness of goodness, nor grace, nor power, nor truth, nor salvation, nor redemption; nor do we find any one at all of those names which are employed by Scripture for the glory of the Only-begotten, either belonging to the creation or employed concerning it,--not to speak of those more exalted words, "I am in the Father, and the Father in Me [892] ," and, "He that hath seen Me hath seen the Father [893] ," and, "None hath seen the Son, save the Father [894] ." If indeed our doctrine allowed us to claim for the creation things so many and so great as these, he might have been right in thinking that we ought to attach what we observe in it to our conceptions of the Only-begotten also, since the transfer would be from kindred subjects to one nearly allied. But if all these concepts and names involve communion with the Father, while they transcend our notions of the creation, does not our clever and sharp-witted friend slink away in shame at discussing the nature of the Lord of the Creation by the aid of what he observes in creation, without being aware that the marks which distinguish the creation are of a different sort? The ultimate division of all that exists is made by the line between "created" and "uncreated," the one being regarded as a cause of what has come into being, the other as coming into being thereby. Now the created nature and the Divine essence being thus divided, and admitting no intermixture in respect of their distinguishing properties, we must by no means conceive both by means of similar terms, nor seek in the idea of their nature for the same distinguishing marks in things that are thus separated. Accordingly, as the nature that is in the creation, as the phrase of the most excellent Wisdom somewhere tells us, exhibits "the beginning, ending, and midst of the times [895] " in itself, and extends concurrently with all temporal intervals, we take as a sort of characteristic of the subject this property, that in it we see some beginning of its formation, look on its midst, and extend our expectations to its end. For we have learnt that the heaven and the earth were not from eternity, and will not last to eternity, and thus it is hence clear that those things are both started from some beginning, and will surely cease at some end. But the Divine Nature, being limited in no respect, but passing all limitations on every side in its infinity, is far removed from those marks which we find in creation. For that power which is without interval, without quantity, without circumscription, having in itself all the ages and all the creation that has taken place in them, and over-passing at all points, by virtue of the infinity of its own nature, the unmeasured extent of the ages, either has no mark which indicates its nature, or has one of an entirely different sort, and not that which the creation has. Since, then, it belongs to the creation to have a beginning, that will be alien from the uncreated nature which belongs to the creation. For if any one should venture to suppose the existence of the Only-begotten Son to be, like the creation, from any beginning comprehensible by us, he must certainly append to his statement concerning the Son the rest also of the sequence [896] ; for it is not possible to avoid acknowledging, together with the beginning, that also which follows from it. For just as if one were to admit some person to be a man in all [897] the properties of his nature, he would observe that in this confession he declared him to be an animal and rational, and whatever else is conceived of man, so by the same reasoning, if we should understand any of the properties of creation to be present in the Divine essence, it will no longer be open to us to refrain from attaching to that pure Nature the rest of the list of the attributes contemplated therein. For the "beginning" will demand by force and compulsion that which follows it; for the "beginning," thus conceived, is a beginning of what comes after it, in such a sense, that if they are, it is, and if the things connected with it are removed, the antecedent also would not remain [898] . Now as the book of Wisdom speaks of "midst" and "end" as well as of "beginning," if we assume in the Nature of the Only-begotten, according to the heretical dogma, some beginning of existence defined by a certain mark of time, the book of Wisdom will by no means allow us to refrain from subjoining to the "beginning" a "midst" and an "end" also. If this should be done we shall find, as the result of our arguments, that the Divine word shows us that the Deity is mortal. For if, according to the book of Wisdom, the "end" is a necessary consequence of the "beginning," and the idea of "midst" is involved in that of extremes, he who allows one of these also potentially maintains the others, and lays down bounds of measure and limitation for the infinite Nature. And if this is impious and absurd, the giving a beginning to that argument which ends in impiety deserves equal, or even greater censure; and the beginning of this absurd doctrine was seen to be the supposition that the life of the Son was circumscribed by some beginning. Thus one of two courses is before them: either they must revert to sound doctrine under the compulsion of the foregoing arguments, and contemplate Him Who is of the Father in union with the Father's eternity, or if they do not like this, they must limit the eternity of the Son in both ways, and reduce the limitless character of His life to non-existence by a beginning and an end. And, granted that the nature both of souls and of the angels has no end, and is no way hindered from going on to eternity, by the fact of its being created, and having the beginning of its existence from some point of time, so that our adversaries can use this fact to assert a parallel in the case of Christ, in the sense that He is not from eternity, and yet endures everlastingly,--let any one who advances this argument also consider the following point, how widely the Godhead differs from the creation in its special attributes. For to the Godhead it properly belongs to lack no conceivable thing which is regarded as good, while the creation attains excellence by partaking in something better than itself; and further, not only had a beginning of its being, but also is found to be constantly in a state of beginning to be in excellence, by its continual advance in improvement, since it never halts at what it has reached, but all that it has acquired [899] becomes by participation a beginning of its ascent to something still greater, and it never ceases, in Paul's phrase, "reaching forth to the things that are before," and "forgetting the things that are behind [900] ." Since, then, the Godhead is very life, and the Only-begotten God is God, and life, and truth, and every conceivable thing that is lofty and Divine, while the creation draws from Him its supply of good, it may hence be evident that if it is in life by partaking of life, it will surely, if it ceases from this participation, cease from life also. If they dare, then, to say also of the Only-begotten God those things which it is true to say of the creation, let them say this too, along with the rest, that He has a beginning of His being like the creation, and abides in life after the likeness of souls. But if He is the very life, and needs not to have life in Himself ab extra, while all other things are not life, but are merely participants in life, what constrains us to cancel, by reason of what we see in creation, the eternity of the Son? For that which is always unchanged as regards its nature, admits of no contrary, and is incapable of change to any other condition: while things whose nature is on the boundary line have a tendency that shifts either way, inclining at will to what they find attractive [901] . If, then, that which is truly life is contemplated in the Divine and transcendent nature, the decadence thereof will surely, as it seems, end in the opposite state [902] .
Now the meaning of "life" and "death" is manifold, and not always understood in the same way. For as regards the flesh, the energy and motion of the bodily senses is called "life," and their extinction and dissolution is named "death." But in the case of the intellectual nature, approximation to the Divine is the true life, and decadence therefrom is named "death": for which reason the original evil, the devil, is called both "death," and the inventor of death: and he is also said by the Apostle to have the power of death [903] . As, then, we obtain, as has been said, from the Scriptures, a twofold conception of death, He Who is truly unchangeable and immutable "alone hath immortality," and dwells in light that cannot be attained or approached by the darkness of wickedness [904] : but all things that participate in death, being far removed from immortality by their contrary tendency, if they fall away from that which is good, would, by the mutability of their nature, admit community with the worse condition, which is nothing else than death, having a certain correspondence with the death of the body. For as in that case the extinction of the activities of nature is called death, so also, in the case of the intellectual being, the absence of motion towards the good is death and departure from life; so that what we perceive in the bodiless creation [905] does not clash with our argument, which refutes the doctrine of heresy. For that form of death which corresponds to the intellectual nature (that is, separation from God, Whom we call Life) is, potentially, not separated even from their nature; for their emergence from non-existence shows mutability of nature; and that to which change is in affinity is hindered from participation in the contrary state by the grace of Him Who strengthens it: it does not abide in the good by its own nature: and such a thing is not eternal. If, then, one really speaks truth in saying that we ought not to estimate the Divine essence and the created nature in the same way, nor to circumscribe the being of the Son of God by any beginning, lest, if this be granted, the other attributes of creation should enter in together with our acknowledgment of this one, the absurd character of the teaching of that man, who employs the attributes of creation to separate the Only-begotten God from the eternity of the Father, is clearly shown. For as none other of the marks which characterize the creation appears in the Maker of the creation, so neither is the fact that the creation has its existence from some beginning a proof that the Son was not always in the Father,--that Son, Who is Wisdom, and Power, and Light, and Life, and all that is conceived of in the bosom of the Father.
