Who then might this Maker be? For this is a point most necessary to make plain, lest, from ignorance with regard to him, a man should suppose the wrong maker, and fall once more into the same old godless error, but I think no one is really in doubt about it. For if our argument has proved that the gods of the poets are no gods, and has convicted of error those that deify creation, and in general has shown that the idolatry of the heathen is godlessness and impiety, it strictly follows from the elimination of these that the true religion is with us, and that the God we worship and preach is the only true One, Who is Lord of Creation and Maker of all existence. 2. Who then is this, save the Father of Christ, most holy and above all created existence, Who like an excellent pilot, by His own Wisdom and His own Word, our Lord and Saviour Christ, steers and preserves and orders all things, and does as seems to Him best? But that is best which has been done, and which we see taking place, since that is what He wills; and this a man can hardly refuse to believe. 3. For if the movement of creation were irrational, and the universe were borne along without plan, a man might fairly disbelieve what we say. But if it subsist in reason and wisdom and skill, and is perfectly ordered throughout, it follows that He that is over it and has ordered it is none other than the [reason or] Word of God. 4. But by Word I mean, not that which is involved and inherent in all things created, which some are wont to call the seminal principle, which is without soul and has no power of reason or thought, but only works by external art, according to the skill of him that applies it—nor such a word as belongs to rational beings and which consists of syllables, and has the air as its vehicle of expression—but I mean the living and powerful Word of the good God, the God of the Universe, the very Word which is God, Who while different from things that are made, and from all Creation, is the One own Word of the good Father, Who by His own providence ordered and illumines this Universe. 5. For being the good Word of the Good Father He produced the order of all things, combining one with another things contrary, and reducing them to one harmonious order. He being the Power of God and Wisdom of God causes the heaven to revolve, and has suspended the earth, and made it fast, though resting upon nothing, by His own nod. Illumined by Him, the sun gives light to the world, and the moon has her measured period of shining. By reason of Him the water is suspended in the clouds; the rains shower upon the earth, and the sea is kept within bounds, while the earth bears grasses and is clothed with all manner of plants. 6. And if a man were incredulously to ask, as regards what we are saying, if there be a Word of God at all, such an one would indeed be mad to doubt concerning the Word of God, but yet demonstration is possible from what is seen, because all things subsist by the Word and Wisdom of God, nor would any created thing have had a fixed existence had it not been made by reason, and that reason the Word of God, as we have said.
41. The Presence of the Word in nature necessary, not only for its original Creation, but also for its permanence.
But though He is Word, He is not, as we said, after the likeness of human words, composed of syllables; but He is the unchanging Image of His own Father. For men, composed of parts and made out of nothing, have their discourse composite and divisible. But God possesses true existence and is not composite, wherefore His Word also has true Existence and is not composite, but is the one and only-begotten God, Who proceeds in His goodness from the Father as from a good Fountain, and orders all things and holds them together. 2. But the reason why the Word, the Word of God, has united Himself with created things is truly wonderful, and teaches us that the present order of things is none otherwise than is fitting. For the nature of created things, inasmuch as it is brought into being out of nothing, is of a fleeting sort, and weak and mortal, if composed of itself only. But the God of all is good and exceeding noble by nature,— and therefore is kind. For one that is good can grudge nothing: for which reason he does not grudge even existence, but desires all to exist, as objects for His loving-kindness. 3. Seeing then all created nature, as far as its own laws were concerned, to be fleeting and subject to dissolution, lest it should come to this and lest the Universe should be broken up again into nothingness, for this cause He made all things by His own eternal Word, and gave substantive existence to Creation, and moreover did not leave it to be tossed in a tempest in the course of its own nature, lest it should run the risk of once more dropping out of existence; but, because He is good He guides and settles the whole Creation by His own Word, Who is Himself also God, that by the governance and providence and ordering action of the Word, Creation may have light, and be enabled to abide always securely. For it partakes of the Word Who derives true existence from the Father, and is helped by Him so as to exist, lest that should come to it which would have come but for the maintenance of it by the Word,— namely, dissolution—“for He is the Image of the invisible God, the first-born of all Creation, for through Him and in Him all things consist, things visible and things invisible, and He is the Head of the Church,” as the ministers of truth teach in their holy writings.
