Against Eunomius

If then the appellations, as Eunomius says, indicate relationship, and the existence of relationship is observed in the things, not in the mere sound of the words (and by things I mean the things conceived in themselves, if it be not over-bold thus to speak of the Son and the Father), who would deny that the very champion of blasphemy has by his own action been dragged into the advocacy of orthodoxy, overthrowing by his own means his own arguments, and proclaiming community of essence in the case of the Divine doctrines?

For the argument that he unwillingly casts into the scale on the side of truth does not speak falsely as regards this point—that He would not have been called Son if the natural conception of the names did not verify this calling. For as a bench is not called the son of the workman, and no sane man would say that the builder engendered the house, and we do not say that the vineyard is the “product” of the vine-dresser, but call what a man makes his work, and him who is begotten of him the son of a man, (in order, I suppose, that the proper meaning might be attached by means of the names to the respective subjects,) so too, when we are taught that the Only-begotten is Son of God, we do not by this appellation understand a creature of God, but what the word “Son” in its signification really displays.

And even though wine be named by Scripture the “product” of the vine, not even so will our argument with regard to the orthodox doctrine suffer by this identity of name. For we do not call wine the “product” of the oak, nor the acorn the “product” of the vine, but we use the word only if there is some natural community between the “product” and that from which it comes. For the moisture in the vine, which is drawn out from the root through the stem by the pith, is, in its natural power, water: but, as it passes in orderly sequence along the ways of nature, and flows from the lowest to the highest, it changes to the quality of wine, a change to which the rays of the sun contribute in some degree, which by their warmth draw out the moisture from the depth to the shoots, and by a proper and suitable process of ripening make the moisture wine: so that, so far as their nature is concerned, there is no difference between the moisture that exists in the vine and the wine that is produced from it.

For the one form of moisture comes from the other, and one could not say that the cause of wine is anything else than the moisture which naturally exists in the shoots. But, so far as moisture is concerned, the differences of quality produce no alteration, but are found when some peculiarity discerns the moisture which is in the form of wine from that which is in the shoots, one of the two forms being accompanied by astringency, or sweetness, or sourness, so that in substance the two are the same, but are distinguished by qualitative differences.

As, therefore, when we hear from Scripture that the Only-begotten God is Son of man, we learn by the kindred expressed in the name His kinship with true man, so even, if the Son be called, in the adversaries' phrase, a “product,” we none the less learn, even by this name, His kinship in essence with Him that has “produced” Him, by the fact that wine, which is called the “product” of the vine has been found not to be alien, as concerns the idea of moisture, from the natural power that resides in the vine.

Indeed, if one were judiciously to examine the things that are said by our adversaries, they tend to our doctrine, and their sense cries out against their own fabrications, as they strive at all points to establish their “difference in essence.” Yet it is by no means an easy matter to conjecture whence they were led to such conceptions. For if the appellation of “Son” does not merely signify “being from something,” but by its signification presents to us specially, as Eunomius himself says, relationship in point of nature, and wine is not called the “product” of an oak, and those “products” or “generation of vipers,” of which the Gospel somewhere speaks, are snakes and not sheep, it is clear, that in the case of the Only-begotten also, the appellation of “Son” or of “product” would not convey the meaning of relationship to something of another kind: but even if, according to our adversaries' phrase, He is called a “product of generation,” and the name of “Son,” as they confess, has reference to nature, the Son is surely of the essence of Him Who has generated or “produced” Him, not of that of some other among the things which we contemplate as external to that nature. And if He is truly from Him, He is not alien from all that belongs to Him from Whom He is, as in the other cases too it was shown that all that has its existence from anything by way of generation is clearly of the same kind as that from whence it came.
