On the Holy Trinity

¹⁷ What then is love? Will it not be an image? Will it not be a word? Will it not be begotten? For why does the mind beget its knowledge when it knows itself, and not beget its love when it loves itself? For if it is the cause of its own knowing, for the reason that it is knowable, it is also the cause of its own love because it is lovable. It is hard, then, to say why it does not beget both. For there is a further question also respecting the supreme Trinity itself, the omnipotent God the Creator, after whose image man is made, which troubles men, whom the truth of God invites to the faith by human speech; viz. why the Holy Spirit is not also to be either believed or understood to be begotten by God the Father, so that He also may be called a Son. And this question we are endeavoring in some way to investigate in the human mind, in order that from a lower image, in which our own nature itself as it were answers, upon being questioned, in a way more familiar to ourselves, we may be able to direct a more practised mental vision from the enlightened creature to the unchangeable light; assuming, however, that the truth itself has persuaded us, that as no Christian doubts the Word of God to be the Son, so that the Holy Spirit is love. Let us return, then, to a more careful questioning and consideration upon this subject of that image which is the creature, that is, of the rational mind; wherein the knowledge of some things coming into existence in time, but which did not exist before, and the love of some things which were not loved before, opens to us more clearly what to say: because to speech also itself, which must be disposed in time, that thing is easier of explanation which is comprehended in the order of time.

18. First, therefore, it is clear that a thing may possibly be knowable, that is, such as can be known, and yet that it may be unknown; but that it is not possible for that to be known which is not knowable. Wherefore it must be clearly held that everything whatsoever that we know begets at the same time in us the knowledge of itself; for knowledge is brought forth from both, from the knower and from the thing known. When, therefore, the mind knows itself, it alone is the parent of its own knowledge; for it is itself both the thing known and the knower of it. But it was knowable to itself also before it knew itself, only the knowledge of itself was not in itself so long as it did not know itself. In knowing itself, then, it begets a knowledge of itself equal to itself; since it does not know itself as less than itself is, nor is its knowledge the knowledge of the essence of some one else, not only because itself knows, but also because it knows itself, as we have said above. What then is to be said of love; why, when the mind loves itself, it should not seem also to have begotten the love of itself? For it was lovable to itself even before it loved itself since it could love itself; just as it was knowable to itself even before it knew itself, since it could know itself. For if it were not knowable to itself, it never could have known itself; and so, if it were not lovable to itself, it never could have loved itself. Why therefore may it not be said by loving itself to have begotten its own love, as by knowing itself it has begotten its own knowledge? Is it because it is thereby indeed plainly shown that this is the principle of love, whence it proceeds? For it proceeds from the mind itself, which is lovable to itself before it loves itself, and so is the principle of its own love by which it loves itself: but that this love is not therefore rightly said to be begotten by the mind, as is the knowledge of itself by which the mind knows itself, because in the case of knowledge the thing has been found already, which is what we call brought forth or discovered; and this is commonly preceded by an inquiry such as to find rest when that end is attained. For inquiry is the desire of finding, or, what is the same thing, of discovering. But those things which are discovered are as it were brought forth, whence they are like offspring; but wherein, except in the case itself of knowledge? For in that case they are as it were uttered and fashioned. For although the things existed already which we found by seeking, yet the knowledge of them did not exist, which knowledge we regard as an offspring that is born. Further, the desire (appetitus) which there is in seeking proceeds from him who seeks, and is in some way in suspense, and does not rest in the end whither it is directed, except that which is sought be found and conjoined with him who seeks. And this desire, that is, inquiry—although it does not seem to be love, by which that which is known is loved, for in this case we are still striving to know—yet it is something of the same kind. For it can be called will (voluntas),since every one who seeks wills (vult) to find; and if that is sought which belongs to knowledge, every one who seeks wills to know. But if he wills ardently and earnestly, he is said to study (studere): a word that is most commonly employed in the case of pursuing and obtaining any branches of learning. Therefore, the bringing forth of the mind is preceded by some desire, by which, through seeking and finding what we wish to know, the offspring, viz. knowledge itself, is born. And for this reason, that desire by which knowledge is conceived and brought forth, cannot rightly be called the bringing forth and the offspring; and the same desire which led us to long for the knowing of the thing, becomes the love of the thing when known, while it holds and embraces its accepted offspring, that is, knowledge, and unites it to its begetter. And so there is a kind of image of the Trinity in the mind itself, and the knowledge of it, which is its offspring and its word concerning itself, and love as a third, and these three are one, and one substance. Neither is the offspring less, since the mind knows itself according to the measure of its own being; nor is the love less, since it loves itself according to the measure both of its own knowledge and of its own being.
