IV. Epistle to Dionysius Bishop of Rome
From the First Book.
1. There certainly was not a time when God was not the Father.
2. Neither, indeed, as though He had not brought forth these things, did God afterwards beget the Son, but because the Son has existence not flora Himself, but from the Father.
And after a few words he says of the Son Himself:—
3. Being the brightness of the eternal Light, He Himself also is absolutely eternal. For since light is always in existence, it is manifest that its brightness also exists, because light is perceived to exist from the fact that it shines, and it is impossible that light should not shine. And let us once more come to illustrations. If the sun exists, there is also day; if nothing of this be manifest, it is impossible that the sun should be there. If then the sun were eternal, the day would never end; but now, for such is not really the state of the case, the day begins with the beginning of the sun, and ends with its ending. But God is the eternal Light, which has neither had a beginning, nor shall ever fail. Therefore the eternal brightness shines forth before Him, and co-exists with Him, in that, existing without a beginning, and always begotten, He always shines before Him; and He is that Wisdom which says, “I was that wherein He delighted, and I was daily His delight before His face at all times.”
And a little after he thus pursues his discourse from the same point:—
4. Since, therefore, the Father is eternal, the Son also is eternal, Light of Light. For where there is the begetter, there is also the offspring. And if there is no offspring, how and of what can He be the begetter? But both are, and always are. Since, then, God is the Light, Christ is the Brightness. And since He is a Spirit— for says He, “God is a Spirit” — fittingly again is Christ called Breath; for “He,” says He, “is the breath of God's power.”
And again he says:—
5. Moreover, the Son alone, always co-existing with the Father, and filled with Him who is, Himself also is, since He is of the Father.
From the Same First Book.
6. But when I spoke of things created, and certain works to be considered, I hastily put forward illustrations of such things, as it were little appropriate, when I said neither is the plant the same as the husbandman, nor the boat the same as the boatbuilder. But then I lingered rather upon things suitable and more adapted to the nature of the thing, and I unfolded in many words, by various carefully considered arguments, what things were more true; which things, moreover, I have set forth to you in another letter. And in these things I have also proved the falsehood of the charge which they bring against me— to wit, that I do not maintain that Christ is consubstantial with God. For although I say that I have never either found or read this word in the sacred Scriptures, yet other reasonings, which I immediately subjoined, are in no wise discrepant from this view, because I brought forward as an illustration human offspring, which assuredly is of the same kind as the begetter; and I said that parents are absolutely distinguished from their children by the fact alone that they themselves are not their children, or that it would assuredly be a matter of necessity that there would neither be parents nor children. But, as I said before, I have not the letter in my possession, on account of the present condition of affairs; otherwise I would have sent you the very words that I then wrote, yea, and a copy of the whole letter, and I will send it if at any time I shall have the opportunity. I remember, further, that I added many similitudes from things kindred to one another. For I said that the plant, whether it grows up from seed or from a root, is different from that whence it sprouted, although it is absolutely of the same nature; and similarly, that a river flowing from a spring takes another form and name: for that neither is the spring called the river, nor the river the spring, but that these are two things, and that the spring indeed is, as it were, the father, while the river is the water from the spring. But they feign that they do not see these things and the like to them which are written, as if they were blind; but they endeavour to assail me from a distance with expressions too carelessly used, as if they were stones, not observing that on things of which they are ignorant, and which require interpretation to be understood, illustrations that are not only remote, but even contrary, will often throw light.
From the Same First Book.
7. It was said above that God is the spring of all good things, but the Son was called the river flowing from Him; because the word is an emanation of the mind, and— to speak after human fashion— is emitted from the heart by the mouth. But the mind which springs forth by the tongue is different from the word which exists in the heart. For this latter, after it has emitted the former, remains and is what it was before; but the mind sent forth flies away, and is carried everywhere around, and thus each is in each although one is from the other, and they are one although they are two. And it is thus that the Father and the Son are said to be one, and to be in one another.
From the Second Book.
8. The individual haines uttered by me can neither be separated from one another, nor parted. I spoke of the Father, and before I made mention of the Son I already signified Him in the Father. I added the Son; and the Father, even although I had not previously named Him, had already been absolutely comprehended in the Son. I added the Holy Spirit; but, at the same time, I conveyed under the name whence and by whom He proceeded. But they are ignorant that neither the Father, in that He is Father, can be separated from the Son, for that name is the evident ground of coherence and conjunction; nor can the Son be separated from the Father, for this word Father indicates association between them. And there is, moreover, evident a Spirit who can neither be disjoined from Him who sends, nor from Him who brings Him. How, then, should I who use such names think that these are absolutely divided and separated the one from the other?
After a few words he adds:—
9. Thus, indeed, we expand the indivisible Unity into a Trinity; and again we contract the Trinity, which cannot be diminished, into a Unity.
From the Same Second Book.
10. But if any quibbler, from the fact that I said that God is the Maker and Creator of all things, thinks that I said that He is also Creator of Christ, let him observe that I first called Him Father, in which word the Son also is at the same time expressed. For after I called the Father the Creator, I added, Neither is He the Father of those things whereof He is Creator, if He who begot is properly understood to be a Father (for we will consider the latitude of this word Father in what follows). Nor is a maker a father, if it is only a framer who is called a maker. For among the Greeks, they who are wise are said to be makers of their books. The apostle also says, “a doer (scil. maker) of the law.” Moreover, of matters of the heart, of which kind are virtue and vice, men are called doers (scil. makers); after which manner God said, “I expected that it should make judgment, but it made iniquity.”
