He further shows that the pretemporal generation of the Son is not the subject of influences drawn from ordinary and carnal generation, but is without beginning and without end, and not according to the fabrications constructed by Eunomius, in ignorance of His power, from the statements of Plato concerning the souland from the sabbath rest of the Hebrews
It remains to consider his support of his point by “the Divine laws,” by which he undertakes to show both an end and a beginning of the generation of the Son. “God,” he says, “willing that the law of creation should be impressed upon the Hebrews, did not appoint the first day of generation for the end of creation, or to be the evidence of its beginning; for He gave them as the memorial of the creation, not the first day of generation, but the seventh, whereon He rested from His works.” Will any one believe that this was written by Eunomius, and that the words cited have not been inserted by us, by way of misrepresenting his composition so as to make him appear ridiculous to our readers, in dragging in to prove his point matters that have nothing to do with the question? For the matter in hand was to show, as he undertook to do, that the Son, not previously existing, came into being; and that in being generated, He took a beginning of generation, and of cessation —His generation being protracted in time, as it were by a kind of travail. And what is his resource for establishing this? The fact that the people of the Hebrews, according to the Law, keep sabbath on the seventh day! How well the evidence agrees with the matter in hand! Because the Jew honours his sabbath by idleness, the fact, as he says, is proved that the Lord both had a beginning of birth and ceased being born! How many other testimonies on this matter has our author passed by, not at all of less weight than that which he employs to establish the point at issue!— the circumcision on the eighth day, the week of unleavened bread, the mystery on the fourteenth day of the moon's course, the sacrifices of purification, the observation of the lepers, the ram, the calf, the heifer, the scapegoat, the he-goat. If these things are far removed from the point, let those who are so much interested in the Jewish mysteries tell us how that particular matter is within range of the question. We judge it to be mean and unmanly to trample on the fallen, and shall proceed to enquire, from what follows in his writings, whether there is anything there of such a kind as to give trouble to his opponent. All, then, that he maintains in the next passage, as to the impropriety of supposing anything intermediate between the Father and the Son, I shall pass by, as being, in a sense, in agreement with our doctrine. For it would be alike undiscriminating and unfair not to distinguish in his remarks what is irreproachable, and what is blamable, seeing that, while he fights against his own statements, he does not follow his own admissions, speaking of the immediate character of the connection while refusing to admit its continuity, and conceiving that nothing was before the Son and having some suspicion that the Son was while yet contending that He came into being when He was not. We shall spend but a short time on these points (since the argument has already been established beforehand), and then proceed to handle the arguments proposed.
It is not allowable for the same person to set nothing above the existence of the Only-begotten, and to say that before His generation He was not, but that He was generated then when the Father willed. For “then” and “when” have a sense which specially and properly refers to the denoting of time, according to the common use of men who speak soundly, and according to their signification in Scripture. One may take “then shall they say among the heathen,” and “when I sent you” and “then shall the kingdom of heaven be likened,” and countless similar phrases through the whole of Scripture, to prove this point, that the ordinary Scriptural use employs these parts of speech to denote time. If therefore, as our opponent allows, time was not, the signifying of time surely disappears too: and if this did not exist, it will necessarily be replaced by eternity in our conception. For in the phrase “was not” there is surely implied “once”: as, if he should speak of “not being,” without the qualification “once,” he would also deny his existence now: but if he admits His present existence, and contends against His eternity, it is surely not “not being” absolutely, but “not being” once which is present to his mind. And as this phrase is utterly unreal, unless it rests upon the signification of time, it would be foolish and idle to say that nothing was before the Son, and yet to maintain that the Son did not always exist. For if there is neither place nor time, nor any other creature where the Word that was in the beginning is not, the statement that the Lord “once was not” is entirely removed from the region of orthodox doctrine. So he is at variance not so much with us as with himself, who declares that the Only-begotten both was and was not. For in confessing that the conjunction of the Son with the Father is not interrupted by anything, He clearly testifies to His eternity. But if he should say that the Son was not in the Father, we shall not ourselves say anything against such a statement, but shall oppose to it the Scripture which declares that the Son is in the Father, and the Father in the Son, without adding to the phrase “once” or “when” or “then,” but testifying His eternity by this affirmative and unqualified utterance.
