Athanasius of Alexandria (c. 296–298 – 2 May 373), also called Athanasius the Great, was a Christian theologian and the 20th patriarch of Alexandria.  In 325, at age 27, Athanasius began his leading role against the Arians as a deacon and assistant to Bishop Alexander of Alexandria during the First Council of Nicaea.

40. The rationality and order of the Universe proves that it is the work of the Reason or Word of God.

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 [ John 1:1 ], 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.

42. This function of the Word described at length.

The holy Word of the Father, then, almighty and all-perfect, uniting with the universe and having everywhere unfolded His own powers, and having illumined all, both things seen and things invisible, holds them together and binds them to Himself, having left nothing void of His own power, but on the contrary quickening and sustaining all things everywhere, each severally and all collectively; while He mingles in one the principles of all sensible existence, heat namely and cold and wet and dry, and causes them not to conflict, but to make up one concordant harmony.

2. By reason of Him and His power, fire does not fight with cold nor wet with dry, but principles mutually opposed, as if friendly and brotherly combine together, and give life to the things we see, and form the principles by which bodies exist. Obeying Him, even God the Word, things on earth have life and things in the heaven have their order. By reason of Him all the sea, and the great ocean, move within their proper bounds, while, as we said above, the dry land grows grasses and is clothed with all manner of diverse plants. And, not to spend time in the enumeration of particulars, where the truth is obvious, there is nothing that is and takes place but has been made and stands by Him and through Him, as also the Divine [ John 1:1 ] says, ​”​ In the beginning was the Word, and the Word was with God, and the Word was God; all things were made by Him, and without Him was not anything made. ​”​

3. For just as though some musician, having tuned a lyre, and by his art adjusted the high notes to the low, and the intermediate notes to the rest, were to produce a single tune as the result, so also the Wisdom of God, handling the Universe as a lyre, and adjusting things in the air to things on the earth, and things in the heaven to things in the air, and combining parts into wholes and moving them all by His beck and will, produces well and fittingly, as the result, the unity of the universe and of its order, Himself remaining unmoved with the Father while He moves all things by His organising action, as seems good for each to His own Father.

4. For what is surprising in His godhead is this, that by one and the same act of will He moves all things simultaneously, and not at intervals, but all collectively, both straight and curved, things above and beneath and intermediate, wet, cold, warm, seen and invisible, and orders them according to their several nature. For simultaneously at His single nod what is straight moves as straight, what is curved also, and what is intermediate, follows its own movement; what is warm receives warmth, what is dry dryness, and all things according to their several nature are quickened and organised by Him, and He produces as the result a marvellous and truly divine harmony.

43. Three similes to illustrate the Word’s relation to the Universe.

And for so great a matter to be understood by an example, let what we are describing be compared to a great chorus. As then the chorus is composed of different people, children, women again, and old men, and those who are still young, and, when one, namely the conductor, gives the sign, each utters sound according to his nature and power, the man as a man, the child as a child, the old man as an old man, and the young man as a young man, while all make up a single harmony;

2. or as our soul at one time moves our several senses according to the proper function of each, so that when some one object is present all alike are put in motion, and the eye sees, the ear hears, the hand touches, the smell takes in odour, and the palate tastes—and often the other parts of the body act too, as for instance if the feet walk;

3. or, to make our meaning plain by yet a third example, it is as though a very great city were built, and administered under the presence of the ruler and king who has built it; for when he is present and gives orders, and has his eye upon everything, all obey; some busy themselves with agriculture, others hasten for water to the aqueducts, another goes forth to procure provisions—one goes to senate, another enters the assembly, the judge goes to the bench, and the magistrate to his court. The workman likewise settles to his craft, the sailor goes down to the sea, the carpenter to his workshop, the physician to his treatment, the architect to his building; and while one is going to the country, another is returning from the country, and while some walk about the town others are going out of the town and returning to it again: but all this is going on and is organised by the presence of the one Ruler, and by his management:

4. in like manner then we must conceive of the whole of Creation, even though the example be inadequate, yet with an enlarged idea. For with the single impulse of a nod as it were of the Word of God, all things simultaneously fall into order, and each discharge their proper functions, and a single order is made up by them all together.

44. The similes applied to the whole Universe, seen and unseen.

For by a nod and by the power of the Divine Word of the Father that governs and presides over all, the heaven revolves, the stars move, the sun shines, the moon goes her circuit, and the air receives the sun’s light and the æther his heat, and the winds blow: the mountains are reared on high, the sea is rough with waves, and the living things in it grow, the earth abides fixed, and bears fruit, and man is formed and lives and dies again, and all things whatever have their life and movement; fire burns, water cools, fountains spring forth, rivers flow, seasons and hours come round, rains descend, clouds are filled, hail is formed, snow and ice congeal, birds fly, creeping things go along, water-animals swim, the sea is navigated, the earth is sown and grows crops in due season, plants grow, and some are young, some ripening, others in their growth become old and decay, and while some things are vanishing others are being engendered and are coming to light.

2. But all these things, and more, which for their number we cannot mention, the worker of wonders and marvels, the Word of God, giving light and life, moves and orders by His own nod, making the universe one. Nor does He leave out of Himself even the invisible powers; for including these also in the universe inasmuch as he is their maker also, He holds them together and quickens them by His nod and by His providence. And there can be no excuse for disbelieving this.

3. For as by His own providence bodies grow and the rational soul moves, and possesses life and thought, and this requires little proof, for we see what takes place—so again the same Word of God with one simple nod by His own power moves and holds together both the visible universe and the invisible powers, allotting to each its proper function, so that the divine powers move in a diviner way, while visible things move as they are seen to do. But Himself being over all, both Governor and King and organising power, He does all for the glory and knowledge of His own Father, so that almost by the very works that He brings to pass He teaches us and says, ​”​ By the greatness and beauty of the creatures proportionably the maker of them is seen [Wisdom 13:5].​”​
