What does the Trinity teach us?

Thus we see that there could be no full revelation of God, but through the Son by the Spirit, and thereby of the Father. The full revelation of the one God is only thus - Father, Son, and Holy Ghost. This, this only, is what the one God is, one identity of will and being, so that they are essentially one and one only, yet distinct in willing and acting (and we can distinguish them in willing and acting: hence we commonly speak of persons), yet never willing or acting but in the common will and unity of nature.

I fear much human language on this. But I affirm that the only full revelation of the one true God is the revelation of Him in the Trinity. Our prayers rise up the same. Through Him (Christ the Son) we have access by one Spirit unto the Father.

So we must be careful in using the terms, first, second and third Persons in the Trinity, not to think there is any difference in importance. The Father is God; the Son is God; the Spirit is God—the Spirit equal in nature and substance to the Father and the Son. If the three Persons of the Godhead are each of them God, it does not follow that there are three Gods. That were impossible. There can be only one God, supreme and unique. Orthodox Christendom believes in three Persons in the Godhead, yet one God, indivisible and unique—the three Persons in the Godhead with one will, one purpose, each sharing to the full every thought and desire and purpose in the minds of the others. We may not, nay cannot, comprehend this. It is a mystery hidden in the Godhead, yet the Godhead is pleased to reveal Itself as Father, Son, and Holy Spirit.

Never in all Scripture is there the slightest ground for saying that the Holy Spirit is an “element of material or physical existence,” but it uses language that can only apply to a Divine Person. We read in Hebrews 9:14 of “The ETERNAL Spirit.” The word, ETERNAL, in this connection, can only predicate Deity. God alone is eternal, a Being without beginning or end. Christians recognise the plain teaching of Scripture—God the Father; God the Son; God the Holy Ghost; not three Gods, for in the nature of things there can be only One supreme, uncreated, self-sustained Being. Christians believe, as taught in the Scriptures, not in a trinity of Gods, but in the triune God—One in Three and Three in One, a mystery beyond the creature’s comprehension, but not beyond the grasp of faith.

Here we must remember that we are dealing with deep and blessed things, things indeed which are beyond our creature minds. Think of Three Persons in One God. They are not Three, in the same sense as They are One, nor are Father, Son and Spirit different names for one and the same Person. The Father counsels and sends the Son; the Son comes to reveal the Godhead, a revelation which stands good for the whole creation; and the Holy Spirit, Whose work is the subjective part, comes to make good, in the souls of the heirs of purpose, that which has been revealed. This revelation includes every family in the heavens and earth, and indeed, it will go out to the place of eternal punishment, for the lake of fire will be an everlasting witness to the righteousness, holiness and majesty of God.

When I say it is by necessity of nature, I do not mean that the divine nature, in which the divine Persons subsist, distinguishes Them; for that nature is one and common to Them all. The nature of the Son is the same with that of the Father; and the nature of the Spirit the same with that of the Father and the Son; and this nature, which They in common partake of, is undivided; it is not parted between Them, so that one has one part, and another a second, and another a third; nor that one has a greater and another a lesser part, which might distinguish Them, but the whole fullness of the Godhead is in each.

“To come to the point—it is the personal relations or distinctive relative properties which belong to each Person which distinguish Them from one another; as paternity in the First Person, filiation in the Second, and spiration in the Third; or, more plainly, it is begetting Psalm 2:7 which peculiarly belongs to the First, and is never ascribed to the Second and Third, which distinguishes Him from Them both, and gives Him; with great propriety, the Name of the Father; and it is being begotten, that is the personal relation, or relative property of the Second Person, hence called the only begotten of the Father (John 1:14), which distinguishes Him from the First and Third, and gives Him the name of the Son; and the relative property, or personal relation of the Third Person is, that He is breathed by the First and Second Persons; hence called the breath of the Almighty, the breath of the mouth of Jehovah the Father, and the breath of the mouth of Christ the Lord, and which is never said of the other Two Persons, and so distinguishes Him from Them; and very pertinently gives Him the name of the Spirit, or breath” (Job 33:4; Psalm 33:6; 2 Thessalonians 2:8). “Body of Divinity,” Book 1., ch. 28.

It will be seen from these extracts that a distinction is drawn between Essence and Person; but as some of my readers may feel a difficulty in gathering up the distinction between the two, I submit the following idea as an illustration, but, be it remembered, only as an illustration. Human nature is distinct, or at least distinguishable, from the individual men and women who in common possess that nature. Thus we may say that, human nature is common to alt men and women, and yet that men and women are distinct from one another as individuals. So, in a high and mysterious sense, the Essence of Deity, which is self-existent, may be distinguished from the Persons in the Deity, who sustain to each other a peculiar and eternal relationship. In Their Essence They are One, in Their Personality They are Three; in Their Essence They are self-existent, in Their Personality They subsist, the Father as Father to the Son, the Son as Son to the Father, the Holy Spirit to both as proceeding from the Father and the Son. Thus we establish a Trinity in Unity. “Hear, O Israel, the Lord our God is one Lord.” There is the unity of the divine Essence. “There are Three that bear record in heaven, the Father, the Word, and the Holy Spirit.” There we have the Trinity of Persons in the divine Essence, “for these Three are One” (1 John 5:7).

We are speaking of our Lord Jesus Christ as “the Son,” and not of His distinctive glories as “the Son of David,” “the Son of Man” and “the Son of God,” nor even of Him as “the Son of the Father,” but rather of His deity as God the Son. The Father is God, the Son is God, and the Holy Spirit is God; yet there are not three Gods, but one God, “God is one” (Gal. 3:20; 1 Tim. 2:5, N.Tr.). Baptism is to the name of the Father and of the Son and of the Holy Spirit,” we are told in Matthew 28:19. This indicates for us the trinity of Persons in the Godhead, all of whom share in that supreme glory.

Here in this very majestic declaration of the Oneness of the Godhead, care is taken to state it consistently with the truth afterwards revealed concerning the Three Persons of the Godhead—Father, Son and Spirit. These Three Persons, of one Substance, completely united in thought, will, purpose, counsel, are not three Gods, but One God, not a tritheism, but a Holy Trinity. We cannot understand the mystery of all this, but this truth lies at the very foundation of the Christian faith.

Without the Trinity love was not known, righteousness, holiness - the spiritual nature of God and purity as such. That is, He never was revealed as He is and always was. All the true nature of God, that is, what He is, without the Trinity is unknown. The Father wills; the Son quickens whom He will; but because we have separate wills, why necessarily have the Father and the Son? The Spirit distributes to whom He will; but this is not separate from the will of the Father and the Son. They have not the same counsel but one counsel, mind, purpose, thought; yet they act distinctly in the manifestation of that counsel. The Father sends the Son, and the Son the Spirit. Yet when the Son comes, He is not thereby separate from the Father. "The Father that dwelleth in me, he doeth the works." So He casts out demons by the Spirit of God; yet He casts them out. There is unity in all that constitutes oneness when we speak spiritually - not unity as one by arriving at the same things, or union, or by being united, as we are by having only one Spirit dwelling in all, but - by being one in eternal being; so that all else flows from that one will and counsel, yet so as that distinction in action in that will is revealed to us: not distinct will, but distinct willing.

It would be wicked folly and gross irreverence on the part of any to attempt to pry into the mysteries of the Trinity or to comprehend the Blessed Person of the Son. On the other hand, it would be an affront to divine grace to despise such revelations of Himself as He has been pleased to make. What has been revealed is necessary to the mature development of the spiritual nature that the Father may receive from us that worship in truth which He seeks; and that in our worship we may intelligently worship One Whom we know (John 4:22) according to His own manifestation in the Son.

That there is unity in the Godhead no Christian denies; while he fully believes three Persons in the Godhead, even the Father, and the Son, and the Holy Spirit (Matt. 28:19).

Nor is this truth to be enfeebled in the least degree. He who allows no more in the Godhead than three aspects of one Person is not a Christian, but a deceiver and an antichrist. He does not confess the fully revealed and true God, not the Godhead merely in three characters but in Three Persons; and so distinct that the Father could send the Son (1 John 4:14), and the Holy Ghost descend on that Son in the presence of the Father and in the consciousness of the Son (Mark 1:10-11), as it was even outwardly before man also (John 1:33-34).
