He then explains the phrase of St. Peter, Him God made Lord and Christ. And herein he sets forth the opposing statement of Eunomius, which he made on account of such phrase against S. Basil, and his lurking revilings and insults
Now that we have had presented to us this preliminary view of existences, it may be opportune to examine the passage before us. It is said, then, by Peter to the Jews, “Him God made Lord and Christ, this Jesus Whom you crucified,” while on our part it is said that it is not pious to refer the word “made” to the Divine Nature of the Only-begotten, but that it is to be referred to that “form of a servant,” which came into being by the Incarnation, in the due time of His appearing in the flesh; and, on the other hand, those who press the phrase the contrary way say that in the word “made” the Apostle indicates the pretemporal generation of the Son. We shall, therefore, set forth the passage in the midst, and after a detailed examination of both the suppositions, leave the judgment of the truth to our reader. Of our adversaries' view Eunomius himself may be a sufficient advocate, for he contends gallantly on the matter, so that in going through his argument word by word we shall completely follow out the reasoning of those who strive against us: and we ourselves will act as champion of the doctrine on our side as best we may, following so far as we are able the line of the argument previously set forth by the great Basil. But do you, who by your reading act as judges in the cause, “execute true judgment,” as one of the prophets says, not awarding the victory to contentious preconceptions, but to the truth as it is manifested by examination. And now let the accuser of our doctrines come forward, and read his indictment, as in a court of law.
In addition, moreover, to what we have mentioned, by his refusal to take the word 'made' as referring to the essence of the Son, and withal by his being ashamed of the Cross, he ascribes to the Apostles what no one even of those who have done their best to speak ill of them on the score of stupidity, lays to their charge; and at the same time he clearly introduces, by his doctrines and arguments, two Christs and two Lords; for he says that it was not the Word Who was in the beginning Whom God made Lord and Christ, but He Who 'emptied Himself to take the form of a servant,' and 'was crucified through weakness.' At all events the great Basil writes expressly as follows:— 'Nor, moreover, is it the intention of the Apostle to present to us that existence of the Only-begotten which was before the ages (which is now the subject of our argument), for he clearly speaks, not of the very essence of God the Word, Who was in the beginning with God, but of Him Who emptied Himself to take the form of a servant, and became conformable to the body of our humiliation, and was crucified through weakness.' And again, 'This is known to any one who even in a small degree applies his mind to the meaning of the Apostle's words, that he is not setting forth to us the mode of the Divine existence, but is introducing the terms which belong to the Incarnation; for he says, Him God made Lord and Christ, this Jesus Whom you crucified, evidently laying stress by the demonstrative word on that in Him which was human and was seen by all.
