Chapter 1.— In What Way We Must Inquire Concerning the Trinity.
We certainly seek a trinity — not any trinity, but that Trinity which is God, and the true and supreme and only God. Let my hearers then wait, for we are still seeking. And no one justly finds fault with such a search, if at least he who seeks that which either to know or to utter is most difficult, is steadfast in the faith. But whosoever either sees or teaches better, finds fault quickly and justly with any one who confidently affirms concerning it. Seek God, he says, and your heart shall live; and lest any one should rashly rejoice that he has, as it were, apprehended it, Seek, he says, His face evermore. And the apostle: If any man, he says, think that he knows anything, he knows nothing yet as he ought to know. But if any man love God, the same is known of Him. He has not said, has known Him, which is dangerous presumption, but is known of Him. So also in another place, when he had said, But now after that you have known God: immediately correcting himself, he says, or rather are known of God. And above all in that other place, Brethren, he says, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before, I press in purpose toward the mark, for the prize of the high calling of God in Christ Jesus. Let us therefore, as many as be perfect, be thus minded. Perfection in this life, he tells us, is nothing else than to forget those things which are behind, and to reach forth and press in purpose toward those things which are before. For he that seeks has the safest purpose, [who seeks] until that is taken hold of whither we are tending, and for which we are reaching forth. But that is the right purpose which starts from faith. For a certain faith is in some way the starting-point of knowledge; but a certain knowledge will not be made perfect, except after this life, when we shall see face to face. Let us therefore be thus minded, so as to know that the disposition to seek the truth is more safe than that which presumes things unknown to be known. Let us therefore so seek as if we should find, and so find as if we were about to seek. For when a man has done, then he begins. Let us doubt without unbelief of things to be believed; let us affirm without rashness of things to be understood: authority must be held fast in the former, truth sought out in the latter. As regards this question, then, let us believe that the Father, and the Son, and the Holy Spirit is one God, the Creator and Ruler of the whole creature; and that the Father is not the Son, nor the Holy Spirit either the Father or the Son, but a trinity of persons mutually interrelated, and a unity of an equal essence. And let us seek to understand this, praying for help from Himself, whom we wish to understand; and as much as He grants, desiring to explain what we understand with so much pious care and anxiety, that even if in any case we say one thing for another, we may at least say nothing unworthy. As, for the sake of example, if we say anything concerning the Father that does not properly belong to the Father, or does belong to the Son, or to the Holy Spirit, or to the Trinity itself; and if anything of the Son which does not properly suit with the Son, or at all events which does suit with the Father, or with the Holy Spirit, or with the Trinity; or if, again, anything concerning the Holy Spirit, which is not fitly a property of the Holy Spirit, yet is not alien from the Father, or from the Son, or from the one God the Trinity itself. Even as now our wish is to see whether the Holy Spirit is properly that love which is most excellent which if He is not, either the Father is love, or the Son, or the Trinity itself; since we cannot withstand the most certain faith and weighty authority of Scripture, saying, God is love. And yet we ought not to deviate into profane error, so as to say anything of the Trinity which does not suit the Creator, but rather the creature, or which is feigned outright by mere empty thought.
Chapter 2.— The Three Things Which are Found in Love Must Be Considered.
And this being so, let us direct our attention to those three things which we fancy we have found. We are not yet speaking of heavenly things, nor yet of God the Father, and Son, and Holy Spirit, but of that inadequate image, which yet is an image, that is, man; for our feeble mind perhaps can gaze upon this more familiarly and more easily. Well then, when I, who make this inquiry, love anything, there are three things concerned — myself, and that which I love, and love itself. For I do not love love, except I love a lover; for there is no love where nothing is loved. Therefore there are three things — he who loves, and that which is loved, and love. But what if I love none except myself? Will there not then be two things — that which I love, and love? For he who loves and that which is loved are the same when any one loves himself; just as to love and to be loved, in the same way, is the very same thing when any one loves himself. Since the same thing is said, when it is said, he loves himself, and he is loved by himself. For in that case to love and to be loved are not two different things: just as he who loves and he who is loved are not two different persons. But yet, even so, love and what is loved are still two things. For there is no love when any one loves himself, except when love itself is loved. But it is one thing to love one’s self, another to love one’s own love. For love is not loved, unless as already loving something; since where nothing is loved there is no love. Therefore there are two things when any one loves himself — love, and that which is loved. For then he that loves and that which is loved are one. Whence it seems that it does not follow that three things are to be understood wherever love is. For let us put aside from the inquiry all the other many things of which a man consists; and in order that we may discover clearly what we are now seeking, as far as in such a subject is possible, let us treat of the mind alone. The mind, then, when it loves itself, discloses two things — mind and love. But what is to love one’s self, except to wish to help one’s self to the enjoyment of self? And when any one wishes himself to be just as much as he is, then the will is on a par with the mind, and the love is equal to him who loves. And if love is a substance, it is certainly not body, but spirit; and the mind also is not body, but spirit. Yet love and mind are not two spirits, but one spirit; nor yet two essences, but one: and yet here are two things that are one, he that loves and love; or, if you like so to put it, that which is loved and love. And these two, indeed, are mutually said relatively. Since he who loves is referred to love, and love to him who loves. For he who loves, loves with some love, and love is the love of some one who loves. But mind and spirit are not said relatively, but express essence. For mind and spirit do not exist because the mind and spirit of some particular man exists. For if we subtract the body from that which is man, which is so called with the conjunction of body, the mind and spirit remain. But if we subtract him that loves, then there is no love; and if we subtract love, then there is no one that loves. And therefore, in so far as they are mutually referred to one another, they are two; but whereas they are spoken in respect to themselves, each are spirit, and both together also are one spirit; and each are mind, and both together one mind. Where, then, is the trinity? Let us attend as much as we can, and let us invoke the everlasting light, that He may illuminate our darkness, and that we may see in ourselves, as much as we are permitted, the image of God.
