Chapter 1.--It is Shown by Reason that in God Three are Not Anything Greater Than One Person.
2. For we say that in this Trinity two or three persons are not anything greater than one of them; which carnal perception does not receive, for no other reason except because it perceives as it can the true things which are created, but cannot discern the truth itself by which they are created; for if it could, then the very corporeal light would in no way be more clear than this which we have said. For in respect to the substance of truth, since it alone truly is, nothing is greater, unless because it more truly is. [662] But in respect to whatsoever is intelligible and unchangeable, no one thing is more truly than another, since all alike are unchangeably eternal; and that which therein is called great, is not great from any other source than from that by which it truly is. Wherefore, where magnitude itself is truth, whatsoever has more of magnitude must needs have more of truth; whatsoever therefore has not more of truth, has not also more of magnitude. Further, whatsoever has more of truth is certainly more true, just as that is greater which has more of magnitude; therefore in respect to the substance of truth that is more great which is more true. But the Father and the Son together are not more truly than the Father singly, or the Son singly. Both together, therefore, are not anything greater than each of them singly. And since also the Holy Spirit equally is truly, the Father and Son together are not anything greater than He, since neither are they more truly. The Father also and the Holy Spirit together, since they do not surpass the Son in truth (for they are not more truly), do not surpass Him either in magnitude. And so the Son and the Holy Spirit together are just as great as the Father alone, since they are as truly. So also the Trinity itself is as great as each several person therein. For where truth itself is magnitude, that is not more great which is not more true: since in regard to the essence of truth, to be true is the same as to be, and to be is the same as to be great; therefore to be great is the same as to be true. And in regard to it, therefore, what is equally true must needs also be equally great.
[662] [In this and the following chapter, the meaning of Augustin will be clearer, if the Latin "veritas," "vera," and "vere," are rendered occasionally, by "reality," "real," and "really." He is endeavoring to prove the equality of the three persons, by the fact that they are equally real (true), and the degree of their reality (truth) is the same. Real being is true being; reality is truth. In common phraseology, truth and reality are synonymous.--W.G.T.S.]
Chapter 2.--Every Corporeal Conception Must Be Rejected, in Order that It May Be Understood How God is Truth.
3. But in respect to bodies, it may be the case that this gold and that gold may be equally true [real], but this may be greater than that, since magnitude is not the same thing in this case as truth; and it is one thing for it to be gold, another to be great. So also in the nature of the soul; a soul is not called great in the same respect in which it is called true. For he, too, has a true [real] soul who has not a great soul; since the essence of body and soul is not the essence of the truth [reality] itself; as is the Trinity, one God, alone, great, true, truthful, the truth. Of whom if we endeavor to think, so far as He Himself permits and grants, let us not think of any touch or embrace in local space, as if of three bodies, or of any compactness of conjunction, as fables tell of three-bodied Geryon; but let whatsoever may occur to the mind, that is of such sort as to be greater in three than in each singly, and less in one than in two, be rejected without any doubt; for so everything corporeal is rejected. But also in spiritual things let nothing changeable that may have occurred to the mind be thought of God. For when we aspire from this depth to that height, it is a step towards no small knowledge, if, before we can know what God is, we can already know what He is not. For certainly He is neither earth nor heaven; nor, as it were, earth and heaven; nor any such thing as we see in the heaven; nor any such thing as we do not see, but which perhaps is in heaven. Neither if you were to magnify in the imagination of your thought the light of the sun as much as you are able, either that it may be greater, or that it may be brighter, a thousand times as much, or times without number; neither is this God. Neither as [663] we think of the pure angels as spirits animating celestial bodies, and changing and dealing with them after the will by which they serve God; not even if all, and there are "thousands of thousands," [664] were brought together into one, and became one; neither is any such thing God. Neither if you were to think of the same spirits as without bodies--a thing indeed most difficult for carnal thought to do. Behold and see, if thou canst, O soul pressed down by the corruptible body, and weighed down by earthly thoughts, many and various; behold and see, if thou canst, that God is truth. [665] For it is written that "God is light;" [666] not in such way as these eyes see, but in such way as the heart sees, when it is said, He is truth [reality]. Ask not what is truth [reality] for immediately the darkness of corporeal images and the clouds of phantasms will put themselves in the way, and will disturb that calm which at the first twinkling shone forth to thee, when I said truth [reality]. See that thou remainest, if thou canst, in that first twinkling with which thou art dazzled, as it were, by a flash, when it is said to thee, Truth [Reality]. But thou canst not; thou wilt glide back into those usual and earthly things. And what weight, pray, is it that will cause thee so to glide back, unless it be the bird-lime of the stains of appetite thou hast contracted, and the errors of thy wandering from the right path?
