9. When, then, we say, Eternal, wise, blessed, are these three the Trinity that is called God? We reduce, indeed, those twelve to this small number of three; but perhaps we can go further, and reduce these three also to one of them. For if wisdom and might, or life and wisdom, can be one and the same thing in the nature of God, why cannot eternity and wisdom, or blessedness and wisdom, be one and the same thing in the nature of God? And hence, as it made no difference whether we spoke of these twelve or of those three when we reduced the many to the small number; so does it make no difference whether we speak of those three, or of that one, to the singularity of which we have shown that the other two of the three may be reduced. What fashion, then, of argument, what possible force and might of understanding, what liveliness of reason, what sharp-sightedness of thought, will set forth how (to pass over now the others) this one thing, that God is called wisdom, is a trinity? For God does not receive wisdom from any one as we receive it from Him, but He is Himself His own wisdom; because His wisdom is not one thing, and His essence another, seeing that to Him to be wise is to be. Christ, indeed, is called in the Holy Scriptures, “the power of God, and the wisdom of God.” But we have discussed in the seventh book how this is to be understood, so that the Son may not seem to make the Father wise; and our explanation came to this, that the Son is wisdom of wisdom, in the same way as He is light of light, God of God. Nor could we find the Holy Spirit to be in any other way than that He Himself also is wisdom, and altogether one wisdom, as one God, one essence. How, then, do we understand this wisdom, which is God, to be a trinity? I do not say, How do we believe this? For among the faithful this ought to admit no question. But supposing there is any way by which we can see with the understanding what we believe, what is that way?
