No one is to be called a Theist, who does not believe in a Personal God, whatever difficulty there may be in defining the word “Personal.” Now it is the belief of Catholics about the Supreme Being, that this essential characteristic of His Nature is reiterated in three distinct ways or modes; so that the Almighty God, instead of being One Person only, which is the teaching of Natural Religion, has Three Personalities, and is at once, according as we view Him in the one or the other of them, the Father, the Son, and the Spirit—a Divine Three, who bear towards Each Other the several relations which those names indicate, and are in that respect distinct from Each Other, and in that alone.

This is the teaching of the Athanasian Creed; viz. [pg 125] that the One Personal God, who is not a logical or physical unity, but a Living Monas, more really one even than an individual man is one—He (“unus,” not “unum,” because of the inseparability of His Nature and Personality),—He at once is Father, is Son, is Holy Ghost, Each of whom is that One Personal God in the fulness of His Being and Attributes; so that the Father is all that is meant by the word “God,” as if we knew nothing of Son, or of Spirit; and in like manner the Son and the Spirit are Each by Himself all that is meant by the word, as if the Other Two were unknown; moreover, that by the word “God” is meant nothing over and above what is meant by the “Father,” or by “the Son,” or by “the Holy Ghost;” and that the Father is in no sense the Son, nor the Son the Holy Ghost, nor the Holy Ghost the Father. Such is the prerogative of the Divine Infinitude, that that One and Single Personal Being, the Almighty God, is really Three, while He is absolutely One.

Indeed, the Catholic dogma may be said to be summed up in this very formula on which St. Augustine lays so much stress, “Tres et Unus,” not merely “Unum;” hence that formula is the key-note, as it may be called, of the Athanasian Creed. In that Creed we testify to the Unus Increatus, to the Unus Immensus, Omnipotens, Deus, and Dominus; yet Each of the Three also is by Himself Increatus, Immensus, Omnipotens, for Each is that One God, though Each is not the Other; Each, as is intimated by Unus Increatus, is the One Personal God of Natural Religion.

That this doctrine, thus drawn out, is of a notional [pg 126] character, is plain; the question before me is whether in any sense it can become the object of real apprehension, that is, whether any portion of it may be considered as addressed to the imagination, and is able to exert that living mastery over the mind, which is instanced as I have shown above, as regards the proposition, “There is a God.”

“There is a God,” when really apprehended, is the object of a strong energetic adhesion, which works a revolution in the mind; but when held merely as a notion, it requires but a cold and ineffective acceptance, though it be held ever so unconditionally. Such in its character is the assent of thousands, whose imaginations are not at all kindled, nor their hearts inflamed, nor their conduct affected, by the most august of all conceivable truths. I ask, then, as concerns the doctrine of the Holy Trinity, such as I have drawn it out to be, is it capable of being apprehended otherwise than notionally? Is it a theory, undeniable indeed, but addressed to the student, and to no one else? Is it the elaborate, subtle, triumphant exhibition of a truth, completely developed, and happily adjusted, and accurately balanced on its centre, and impregnable on every side, as a scientific view, “totus, teres, atque rotundus,” challenging all assailants, or, on the other hand, does it come to the unlearned, the young, the busy, and the afflicted, as a fact which is to arrest them, penetrate them, and to support and animate them in their passage through life? That is, does it admit of being held in the imagination, and being embraced with a real assent? I maintain it does, and that it is the normal faith which every Christian [pg 127] has, on which he is stayed, which is his spiritual life, there being nothing in the exposition of the dogma, as I have given it above, which does not address the imagination, as well as the intellect.

Now let us observe what is not in that exposition;—there are no scientific terms in it. I will not allow that “Personal” is such, because it is a word in common use, and though it cannot mean precisely the same when used of God as when it is used of man, yet it is sufficiently explained by that common use, to allow of its being intelligibly applied to the Divine Nature. The other words, which occur in the above account of the doctrine,—Three, One, He, God, Father, Son, Spirit,—are none of them words peculiar to theology, have all a popular meaning, and are used according to that obvious and popular meaning, when introduced into the Catholic dogma. No human words indeed are worthy of the Supreme Being, none are adequate; but we have no other words to use but human, and those in question are among the simplest and most intelligible that are to be found in language.

There are then no terms in the foregoing exposition which do not admit of a plain sense, and they are there used in that sense; and, moreover, that sense is what I have called real, for the words in their ordinary use stand for things. The words, Father, Son, Spirit, He, One, and the rest, are not abstract terms, but concrete, and adapted to excite images. And these words thus simple and clear, are embodied in simple, clear, brief, categorical propositions. There is nothing abstruse either in the terms themselves, or in their setting. It is otherwise [pg 128] of course with formal theological treatises on the subject of the dogma. There we find such words as substance, essence, existence, form, subsistence, notion, circumincession; and, though these are far easier to understand than might at first sight be thought, still they are doubtless addressed to the intellect, and can only command a notional assent.

It will be observed also that not even the words “mysteriousness” and “mystery” occur in the exposition which I have above given of the doctrine; I omitted them, because they are not parts of the Divine Verity as such, but in relation to creatures and to the human intellect; and because they are of a notional character. It is plain of course even at first sight that the doctrine is an inscrutable mystery, or has an inscrutable mysteriousness; few minds indeed but have theology enough to see this; and if an educated man, to whom it is presented, does not perceive that mysteriousness at once, that is a sure token that he does not rightly apprehend the propositions which contain the doctrine. Hence it follows that the thesis “the doctrine of the Holy Trinity in Unity is mysterious” is indirectly an article of faith. But such an article, being a reflection made upon a revealed truth in an inference, expresses a notion, not a thing. It does not relate to the direct apprehension of the object, but to a judgment of our reason upon the object. Accordingly the mysteriousness of the doctrine is not, strictly speaking, intrinsical to it, as it is proposed to the religious apprehension, though in matter of fact a devotional mind, on perceiving that mysteriousness, will lovingly appropriate [pg 129] it, as involved in the divine revelation; and, as such a mind turns all thoughts which come before it to a sacred use, so will it dwell upon the Mystery of the Trinity with awe and veneration, as a truth befitting, so to say, the Immensity and Incomprehensibility of the Supreme Being.

However, I do not put forward the mystery as the direct object of real or religious apprehension; nor again, the complex doctrine (when it is viewed, per modum unius, as one whole), in which the mystery lies. Let it be observed, it is possible for the mind to hold a number of propositions either in their combination as one whole, or one by one; one by one, with an intelligent perception indeed of each, and of the general direction of each towards the rest, yet of each separately from the rest, for its own sake only, and not in connexion and one with the rest. Thus I may know London quite well, and find my way from street to street in any part of it without difficulty, yet be quite unable to draw a map of it. Comparison, calculation, cataloguing, arranging, classifying, are intellectual acts subsequent upon, and not necessary for, a real apprehension of the things on which they are exercised. Strictly speaking then, the dogma of the Holy Trinity, as a complex whole, or as a mystery, is not the formal object of religious apprehension and assent; but as a number of propositions, taken one by one. That mystery also is of course the object of assent, but it is the notional object; and when presented to religious minds, it is received by them notionally; and again implicitly, viz. in the real assent which they give to the word of God as conveyed [pg 130] to them through the instrumentality of His Church. On these points it may be right to enlarge.

Of course, as I have been saying, a man of ordinary intelligence will be at once struck with the apparent contrariety between the propositions one with another which constitute the Heavenly Dogma, and, by reason of his spontaneous activity of mind and by an habitual association, he will be compelled to view the Dogma in the light of that contrariety,—so much so, that to hold one and all of these separate propositions will be to such a man all one with holding the mystery, as a mystery; and in consequence he will so hold it;—but still, I say, so far he will hold it only with a notional apprehension. He will accurately take in the meaning of each of the dogmatic propositions in its relation to the rest of them, combining them into one whole and embracing what he cannot realize, with an assent, notional indeed, but as genuine and thorough as any real assent can be. But the question is whether a real assent to the mystery, as such, is possible; and I say it is not possible, because, while we can image the separate propositions, we cannot image them all together. We cannot, because the mystery transcends all our experience; we have no experiences in our memory which we can put together, compare, contrast, unite, and thereby transmute into an image of the Ineffable Verity;—certainly; but what is in some degree a matter of experience, what is presented for the imagination, the affections, the devotion, the spiritual life of the Christian to repose upon with a real assent, what stands for things, not for notions only, is each of those propositions taken one by one, and that, not [pg 131] in the case of intellectual and thoughtful minds only, but of all religious minds whatever, in the case of a child or a peasant, as well as of a philosopher.
