Answer to Eunomius' Second Book
Since, then, it is monstrous to regard God as the inventor of such names, lest the names even of these idol gods should seem to have had their origin from God, it will be well not to receive what has been said without inquiry, but to get to the meaning in this case also after the analogy of those things of which number informs us. Well, since it attests the accuracy of our knowledge, when we call one familiar to us by his name, we are here taught that He Who embraces the Universe in His knowledge not only comprehends the total of the aggregate quantity, but has an exact knowledge of the units also that compose it. And therefore the Scripture says not only that He “tells the number of the stars,” but that “He calls them all by their names,” which means that His accurate knowledge extends to the minutest of them, and that He knows each particular respecting them, just as a man knows one who is familiar to him by name. And if any one say that the names given to the stars by God are different ones, unknown to human language, he wanders far away from the truth. For if there were other names of stars, Holy Scripture would not have made mention of those which are in common use among the Greeks, Esaias saying, “Which makes the Pleiads, and Hesperus, and Arcturus, and the Chambers of the South,” and Job making mention of Orion and Aseroth; so that from this it is clear that Holy Scripture employs for our instruction such words as are in common use. Thus we hear in Job of Amalthea's horn, and in Esaias of the Sirens, the former thus naming plenty after the conceit of the Greeks, the latter representing the pleasure derived from hearing, by the figure of the Sirens. As, then, in these cases the inspired word has made use of names drawn from mythological fables, with a view to the advantage of the hearers, so here it freely makes use of the appellations given to the stars by human fancy, teaching us that all things whatsoever that are named among men have their origin from God— the things, not their names. For it does not say Who names, but “Who makes Pleiad, and Hesperus, and Arcturus.” I think, then, it has been sufficiently shown in what I have said that David supports our opinion, in teaching us by this utterance, not that God gives the stars their names, but that He has an exact knowledge of them, after the fashion of men, who have the most certain knowledge of those whom they are able, through long familiarity, to call by their names.
And if we set forth the opinion of most commentators on these words of the Psalmist, that of Eunomius regarding them will be still more convicted of foolishness. For those who have most carefully searched out the sense of the inspired Scripture, declare that not all the works of creation are worthy of the Divine reckoning. For in the Gospel narratives of feeding the multitudes in the wilderness, women and children are not thought worthy of enumeration. And in the account of the Exodus of the children of Israel, those only are enumerated in the roll who were of age to bear arms against their enemies, and to do deeds of valour. For not all names of things are fit to be pronounced by the Divine lips, but the enumeration is only for that which is pure and heavenly, which, by the loftiness of its state remaining pure from all admixture with darkness, is called a star, and the naming is only for that which, for the same reason, is worthy to be registered in the Divine tablets. For of His adversaries He says, “I will not take up their names into my lips.”
But the names which the Lord gives to such stars we may plainly learn from the prophecy of Esaias, which says, “I have called you by your name; you are Mine.” So that if a man makes himself God's possession, his act becomes his name. But be this as the reader pleases. Eunomius, however, adds to his previous statement that the beginnings of creation testify to the fact, that names were given by God to the things which He created; but I think that it would be superfluous to repeat what I have already sufficiently set forth as the result of my investigations; and he may put his own arbitrary interpretation on the word Adam, which, the Apostle tells us, points prophetically to Christ. For no one can be so infatuated, when Paul, by the power of the Spirit, has revealed to us the hidden mysteries, as to count Eunomius a more trustworthy interpreter of Divine things— a man who openly impugns the words of the inspired testimony, and who by his false interpretation of the word would fain prove that the various kinds of animals were not named by Adam. We shall do well, also, to pass over his insolent expressions, and tasteless vulgarity, and foul and disgusting tongue, with its accustomed fluency going on about our Master as “a sower of tares,” and about “a deceptive show of grain, and the blight of Valentinus, and his grain piled in our Master's mind”: and we will veil in silence the rest of his unsavoury talk as we veil putrefying corpses in the ground, that the stench may not prove injurious to many. Rather let us proceed to what remains for us to say. For once more he adduces a dictum of our Master, to this effect. “We call God indestructible and ungenerate, applying these words from different points of view. For when we look to the ages that are past, finding the life of God transcending all limitation, we call Him ungenerate. But when we turn our thoughts to the ages that are yet to come, Him Who is infinite, illimitable, and without end, we call indestructible. As, then, that which has no end of life is indestructible, so that which has no beginning we call ungenerate, representing things so by the faculty of conception.”
