8. And His proper and peculiar, natural and excellent Sonship, St. Paul has declared, who thus speaks of God: "Who spared not His own Son, but for us," who were not His natural sons, "delivered Him up." [2422] For to distinguish Him from those who are not properly sons, He said that He was His own Son. And in the Gospel we read: "This is My beloved Son, in whom I am well pleased." [2423] Moreover, in the Psalms the Saviour says: "The Lord hath said unto Me, Thou art my Son." [2424] Where, showing that He is the true and genuine Son, He signifies that there are no other genuine sons besides Himself. And what, too, is the meaning of this: "From the womb before the morning I begat thee"? [2425] Does He not plainly indicate the natural sonship of paternal bringing forth, which he obtained not by the careful framing of His manners, not by the exercise of and increase in virtue, but by property of nature? Wherefore, the only-begotten Son of the Father, indeed, possesses an indefectible Sonship; but the adoption of rational sons belongs not to them by nature, but is prepared for them by the probity of their life, and by the free gift of God. And it is mutable as the Scripture recognises: "For when the sons of God saw the daughters of men, they took them wives," [2426] etc. And in another place: "I have nourished and brought up children, but they have rebelled against Me," [2427] as we find God speaking by the prophet Isaiah.
9. And though I could say much more, brethren beloved, I purposely omit to do so, as deeming it to be burdensome at great length to call these things to the remembrance of teachers who are of the same mind with myself. For ye yourselves are taught of God, nor are ye ignorant that this doctrine, which hath lately raised its head against the piety of the Church, is that of Ebion and Artemas; nor is it aught else but an imitation of Paul of Samosata, bishop of Antioch, who, by the judgment and counsel of all the bishops, and in every place, was separated from the Church. [2428] To whom Lucian succeeding, remained for many years separate from the communion of three bishops. [2429] And now lately having drained the dregs of their impiety, there have arisen amongst us those who teach this doctrine of a creation from things which are not, [2430] their hidden sprouts, Arius and Achilles, and the gathering of those who join in their wickedness. And three bishops in Syria, having been, in some manner, consecrated on account of their agreement with them, incite them to worse things. But let the judgment concerning these be reserved for your trial. For they, retaining in their memory the words which came to be used with respect to His saving Passion, and abasement, and examination, and what they call His poverty, and in short of all those things to which the Saviour submitted for our sakes, bring them forward to refute His supreme and eternal Godhead. But of those words which signify His natural glory and nobility, and abiding with the Father, they have become unmindful. Such as this: "I and My Father are one," [2431] which indeed the Lord says, not as proclaiming Himself to be the Father, nor to demonstrate that two persons are one; but that the Son of the Father most exactly preserves the expressed likeness of the Father, inasmuch as He has by nature impressed upon Him His similitude in every respect, and is the image of the Father in no way discrepant, and the expressed figure of the primitive exemplar. Whence, also, to Philip, who then was desirous to see Him, the Lord shows this abundantly. For when he said, "Show us the Father," [2432] He answered: "He that hath seen Me, hath seen the Father," since the Father was Himself seen through the spotless and living mirror of the divine image. Similar to which is what the saints say in the Psalms: "In Thy light shall we see light." [2433] Wherefore he that honoureth the Son, honoureth the Father also;" [2434] and with reason, for every impious word which they dare to speak against the Son, has reference to the Father.
10. But after these things, brethren beloved, what is there wonderful in that which I am about to write, if I shall set forth the false calumnies against me and our most pious laity? For those who have set themselves in array against the Godhead of Christ, do not scruple to utter their ungrateful ravings against us. Who will not either that any of the ancients should be compared with them, or suffer that any of those whom, from our earliest years, we have used as instructors should be placed on a level with them. Nay, and they do not think that any of all those who are now our colleagues, has attained even to a moderate amount of wisdom; boasting themselves to be the only men who are wise and divested of worldly possessions, the sole discoverers of dogmas, and that to them alone are those things revealed which have never before come into the mind of any other under the sun. Oh, the impious arrogance! Oh, the immeasurable madness! Oh, the vainglory befitting those that are crazed! Oh, the pride of Satan which has taken root in their unholy souls. The religious perspicuity of the ancient Scriptures caused them no shame, nor did the consentient doctrine of our colleagues concerning Christ keep in check their audacity against Him. Their impiety not even the demons will bear, who are ever on the watch for a blasphemous word uttered against the Son.
11. And let these things be now urged according to our power against those who, with respect to matter which they know nothing of, have, as it were, rolled in the dust against Christ, and have taken in hand to calumniate our piety towards Him. For those inventors of stupid fables say, that we who turn away with aversion from the impious and unscriptural blasphemy against Christ, of those who speak of His coming from the things which are not assert, that there are two unbegottens. For they ignorantly affirm that one of two things must necessarily be said, either that He is from things which are not, or that there are two unbegottens; nor do those ignorant men know how great is the difference between the unbegotten Father, and the things which were by Him created from things which are not, as well the rational as the irrational. Between which two, as holding the middle place, the only begotten nature of God, the Word by which the Father formed all things out of nothing, was begotten of the true Father Himself. As in a certain place the Lord Himself testified, saying, "Every one that loveth Him that begat, loveth Him also that is begotten of Him." [2435]
12. Concerning whom we thus believe, even as the Apostolic Church believes. In one Father unbegotten, who has from no one the cause of His being, who is unchangeable and immutable, who is always the same, and admits of no increase or diminution; who gave to us the Law, the prophets, and the Gospels; who is Lord of the patriarchs and apostles, and all the saints. And in one Lord Jesus Christ, the only-begotten Son of God; not begotten of things which are not, but of Him who is the Father; not in a corporeal manner, by excision or division as Sabellius and Valentinus thought, but in a certain inexplicable and unspeakable manner, according to the words of the prophet cited above: "Who shall declare His generation?" [2436] Since that His subsistence no nature which is begotten can investigate, even as the Father can be investigated by none; because that the nature of rational beings cannot receive the knowledge of His divine generation by the Father. But men who are moved by the Spirit of truth, have no need to learn these things from me, for in our ears are sounding the words before uttered by Christ on this very thing, "No man knoweth the Father, save the Son; and no man knoweth who the Son is, save the Father." [2437] That He is equally with the Father unchangeable and immutable, wanting in nothing, and the perfect Son, and like to the Father, we have learnt; in this alone is He inferior to the Father, that He is not unbegotten. For He is the very exact image of the Father, and in nothing differing from Him. For it is clear that He is the image fully containing all things by which the greatest similitude is declared, as the Lord Himself hath taught us, when He says, "My Father is greater than I." [2438] And according to this we believe that the Son is of the Father, always existing. "For He is the brightness of His glory, the express image of His Father's person." [2439] But let no one take that word always so as to raise suspicion that He is unbegotten, as they imagine who have their senses blinded. For neither are the words, "He was," or "always," or "before all worlds," equivalent to unbegotten. But neither can the human mind employ any other word to signify unbegotten. And thus I think that you understand it, and I trust to your right purpose in all things, since these words do not at all signify unbegotten. For these words seem to denote simply a lengthening out of time, but the Godhead, and as it were the antiquity of the only-begotten, they cannot worthily signify; but they have been employed by holy men, whilst each, according to his capacity, seeks to express this mystery, asking indulgence from the hearers, and pleading a reasonable excuse, in saying, Thus far have we attained. But if there be any who are expecting from mortal lips some word which exceeds human capacity, saying that those things have been done away which are known in part, it is manifest that the words, "He was," and "always," and "before all ages," come far short of what they hoped. And whatever word shall be employed is not equivalent to unbegotten. Therefore to the unbegotten Father, indeed, we ought to preserve His proper dignity, in confessing that no one is the cause of His being; but to the Son must be allotted His fitting honour, in assigning to Him, as we have said, a generation from the Father without beginning, and allotting adoration to Him, so as only piously and properly to use the words, "He was," and "always," and "before all worlds," with respect to Him; by no means rejecting His Godhead, but ascribing to Him a similitude which exactly answers in every respect to the Image and Exemplar of the Father. But we must say that to the Father alone belongs the property of being unbegotten, for the Saviour Himself said, "My Father is greater than I." [2440] And besides the pious opinion concerning the Father and the Son, we confess to one Holy Spirit, as the divine Scriptures teach us; who hath inaugurated both the holy men of the Old Testament, and the divine teachers of that which is called the New. And besides, also, one only Catholic and Apostolic Church, which can never be destroyed, though all the world should seek to make war with it; but it is victorious over every most impious revolt of the heretics who rise up against it. For her Goodman hath confirmed our minds by saying, "Be of good cheer, I have overcome the world." [2441] After this we know of the resurrection of the dead, the first-fruits of which was our Lord Jesus Christ, who in very deed, and not in appearance merely, carried a body, of Mary Mother of God, who in the end of the world came to the human race to put away sin, was crucified and died, and yet did He not thus perceive any detriment to His divinity, being raised from the dead, taken up into heaven, seated at the right hand of majesty.
13. These things in part have I written in this epistle, thinking it burdensome to write out each accurately, even as I said before, because they escape not your religious diligence. Thus do we teach, thus do we preach. These are the apostolic doctrines of the Church, for which also we die, esteeming those but little who would compel us to forswear them, even if they would force us by tortures, and not casting away our hope in them. To these Arius and Achilles opposing themselves, and those who with them are the enemies of the truth, have been expelled from the Church, as being aliens from our holy doctrine, according to the blessed Paul, who says, "If any man preach any other gospel unto you than that ye have received, let him be accursed; even though he feign himself an angel from heaven." [2442] And also, "If any man teach otherwise, and consent not to the wholesome words of our Lord Jesus Christ, and to the doctrine which is according to godliness; he is proud, knowing nothing," [2443] and so forth. These, therefore, who have been anathematized by the brotherhood, let no one of you receive, nor admit of those things which are either said or written by them. For these seducers do always lie, nor will they ever speak the truth. They go about the cities, attempting nothing else but that under the mark of friendship and the name of peace, by their hypocrisy and blandishments, they may give and receive letters, to deceive by means of these a few "silly women, and laden with sins, who have been led captive by them," [2444] and so forth.
