Exodus 4:22

But, however, the majority of interpreters of the parables are deceived by the self-same result as is of very frequent occurrence in the case of embroidering garments with purple. When you think that you have judiciously harmonized the proportions of the hues, and believe yourself to have succeeded in skilfully giving vividness to their mutual combination; presently, when each body (of colour) and (the various) lights are fully developed, the convicted diversity will expose all the error. In the self-same darkness, accordingly, with regard to the parable of the two sons also, they are led by some figures (occurring in it), which harmonize in hue with the present (state of things), to wander out of the path of the true light of that comparison which the subject-matter of the parable presents. …

Now this is again a much greater honor than the first. And this is why he does not say merely, As many as live by the Spirit of God, but, “as many as are led by the Spirit of God,” to show that he would have Him use such power over our life as a pilot doth over a ship, or a charioteer over a pair of horses. And it is not the body only, but the soul itself too, that he is for setting under reins of this sort. For he would not have even that independent, but place its authority also under the power of the Spirit. For lest through a confidence in the Gift of the Font they should turn negligent of their conversation after it, he would say, that even supposing you receive baptism, yet if you are not minded to be “led by the Spirit” afterwards, you lose the dignity bestowed upon you, and the pre-eminence of your adoption. …

But to men who meditate on God’s law day and night, it is indeed needless to write all the proofs of this kind; the above are sufficient to persuade even the most obstinate opponents not to divide the divine titles. One point, however, I cannot endure to omit. He is alleged to have said that there are many Christs but one Son. Into this error I suppose he fell through ignorance. For if he had read the divine Scripture, he would have known that the title of the Son has also been bestowed by our bountiful Lord on many. …

4. Again, I say, on hearing of a Son, under stand it not merely in an improper sense, but as a Son in truth, a Son by nature, without beginning; not as having come out of bondage into a higher state of adoption, but a Son eternally begotten by an inscrutable and incomprehensible generation. And in like manner on hearing of the First-born, think not that this is after the manner of men; for the first-born among men have other brothers also. And it is somewhere written, Israel is My son, My first-born . But Israel is, as Reuben was, a first-born son rejected: for Reuben went up to his father’s couch; and Israel cast his Father’s Son out of the vineyard, and crucified Him.

14. Yet perchance inasmuch as He says, My firstborn Son Israel , some one will interpret the fact that He said, My firstborn , so as to deprive the Son of the characteristic property of birth; as though, because God also applied to Israel the epithet Mine , the adoption of those who have been made sons was misrepresented as though it were an actual birth, and therefore the phrase used of Him, This is My beloved Son , is not solely applicable to the birth of God, since the epithet My is (so it is asserted) shared with those who clearly were not born sons. But that they were not really born, although they are said to have been born, is shewn even from that passage where it is said, A people which shall be born, whom the Lord hath made .

4. Again, hear concerning the title Son of God, by which we have called Him. They say that “though God has no son, ye make that crucified Jesus, the firstborn son of God.” Yet He called Israel “ My first-born, ” when He sent to Pharaoh through Moses and said to him, Israel is My first-born; I have said unto thee, let My Son go to serve Me, and if thou art not willing to let (him) go, lo! I will slay thy son, thy firstborn . And also through the Prophet He testified concerning this, and reproved them and said to the people, Out of Egypt have I called My son. As I called them, so they went and worshipped Baal and offered incense to the graven images. And Isaiah said concerning them, Children have I reared and brought up, and they have rebelled against Me. And again it is written, Ye are the children of the Lord your God . …
