Answer to Eunomius' Second Book
Now that the idea of ungeneracy and the belief in the Divine essence are quite different things may be seen by what he himself has put forward. God, he says, is indestructible and ungenerate by His very essence, as being unmixed and pure from all diversity and difference. This he says of God, Whose essence he declares to be indestructibility and ungeneracy. There are three names, then, that he applies to God, being, indestructibility, ungeneracy. If the idea of these three words in respect of God is one, it follows that the Godhead and these three are identical. Just as if any one, wanting to describe a man, should say that he was a rational, risible, and broad-nailed creature; whereupon, because there is no essential variation from these in the individuals, we say that the terms are equivalent to each other, and that the three things seen in the subject are one thing, viz. the humanity described by these names. If, then, Godhead means this, ungeneracy, indestructibility, being, by doing away with one of these he necessarily does away with the Godhead. For just as we should say that a creature which was neither rational nor risible was not man either, so in the case of these three terms (ungeneracy, indestructibility, being), if the Godhead is described by these, should one of the three be absent, its absence destroys the definition of Godhead. Let him tell us, then, in reply, what opinion he holds of God the Only-begotten. Does he think Him generate or ungenerate? Of course he must say generate, unless he is to contradict himself. If, then, being and indestructibility are equivalent to ungeneracy, and by all of these Godhead is denoted, to Whom ungeneracy is wanting, to Him being and indestructibility must needs be wanting also, and in that case the Godhead also must necessarily be taken away. And thus his blasphemous logic brings him to a twofold conclusion. For if being, and indestructibility, and ungeneracy are applied to God in the same sense, our new God-maker is clearly convicted of regarding the Son created by Him as destructible, by his not regarding Him as ungenerate, and not only so, but altogether without being, through his inability to see Him in the Godhead, as one in whom ungeneracy and indestructibility are not found, since he takes the ungeneracy and indestructibility to be identical with the being. But since in this there is manifest perdition, let some one counsel these unhappy folk to turn to the only course which is left them, and, instead of setting themselves in open opposition to the truth, to allow that each of these terms has its own proper signification, such as may be seen still better from their contraries. For we find ungenerate set against generate, and we understand the indestructible by its opposition to the destructible, and being by contrast with that which has no subsistence. For as that which was not generated is called ungenerate, and that which is not destructible is called indestructible, so that which is not non-existent we call being, and, conversely, as we do not call the generate ungenerate, nor the destructible indestructible, so that which is non-existent we do not call being. Being, then, is discernible in the being this or that, goodness or indestructibility in the being of this or of that kind, generacy or ungeneracy in the manner of the being. And thus the ideas of being, manner, and quality are distinct from each other.
But it will be well, I think, to pass over his nauseating observations (for such we must term his senseless attacks on the method of conception), and dwell more pleasurably on the subject matter of our thought. For all the venom that our disputant has disgorged with the view of overthrowing our Master's speculations in regard to conception, is not of such a kind as to be dangerous to those who come in its way, however stupid they may be and liable to be imposed on. For who is so devoid of understanding as to think that there is anything in what Eunomius says, or to see any ingenuity in his artifices against the truth when he takes our Master's reference to grain (which he meant simply by way of illustration, thereby providing his hearers with a sort of method and introduction to the study of higher instances), and applies it literally to the Lord of all? To think of his assertion that the most becoming cause for God's begetting the Son was His sovereign authority and power, which may be said not only in regard to the universe and its elements, but in regard to beasts and creeping things; and of our reverend theologian teaching that the same is becoming in our conception of God the Only-begotten— or again, of his saying that God was called ungenerate, or Father, or any other name, even before the existence of creatures to call Him such, as being afraid lest, His name not being uttered among creatures as yet unborn, He should be ignorant or forgetful of Himself, through ignorance of His own nature because of His name being unspoken! To think, again, of the insolence of his attack upon our teaching; what acrimony, what subtlety does he display, while attempting to establish the absurdity of what he (Basil) said, namely that He Who was in a manner the Father before all worlds and time, and all sensitive and intellectual nature, must somehow wait for man's creation in order to be named by means of man's conception, not having been so named, either by the Son or by any of the intelligent beings of His creation! Why no one, I imagine, can be so densely stupid as to be ignorant that God the Only-begotten, Who is in the Father, and Who sees the Father in Himself, is in no need of any name or title to make Him known, nor is the mystery of the Holy Spirit, Who searches out the deep things of God, brought to our knowledge by a nominal appellation, nor can the incorporeal nature of supramundane powers name God by voice and tongue. For, in the case of immaterial intellectual nature, the mental energy is speech which has no need of material instruments of communication. For even in the case of human beings, we should have no need of using words and names if we could otherwise inform each other of our pure mental feelings and impulses. But (as things are), inasmuch as the thoughts which arise in us are incapable of being so revealed, because our nature is encumbered with its fleshly surrounding, we are obliged to express to each other what goes on in our minds by giving things their respective names, as signs of their meaning.
But if it were in any way possible by some other means to lay bare the movements of thought, abandoning the formal instrumentality of words, we should converse with one another more lucidly and clearly, revealing by the mere action of thought the essential nature of the things which are under consideration. But now, by reason of our inability to do so, we have given things their special names, calling one Heaven, another Earth, and so on, and as each is related to each, and acts or suffers, we have marked them by distinctive names, so that our thoughts in regard to them may not remain uncommunicated and unknown. But supramundane and immaterial nature being free and independent of bodily envelopment, requires no words or names either for itself or for that which is above it, but whatever utterance on the part of such intellectual nature is recorded in Holy Writ is given for the sake of the hearers, who would be unable otherwise to learn what is to be set forth, if it were not communicated to them by voice and word. And if David in the spirit speaks of something being said by the Lord to the Lord, it is David himself who is the speaker, being unable otherwise to make known to us the teaching of what is meant except by interpreting by voice and word his own knowledge of the mysteries given him by Divine inspiration.
