What does it mean that the Trinity is God in three Persons?

The truth as to the Deity is not that there are Gods—three supreme and omnipotent Beings, each having His own life and acting from Himself—but three in one—Father, Son and Holy Spirit—One God; and though for the sake of accommodation we use the word Person, and speak of three Persons in the Godhead, yet there are not three Persons as we understand persons. Such as Abraham, Isaac, and Jacob were three persons; each having his own separate life.

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.

There are three divine persons: the Father, the Son and the Holy Spirit. Each of them is ‘God’.

For the Son, see questions 2 and 3. For the Father, there are so many references to Him as the ‘God and Father’ (e.g. Eph. 1:3). The Spirit is eternal (Heb. 9:14), omnipresent (Ps. 139:7) and co-equal (‘on the same level with’) the Father and the Son (Mt. 18:19; 2 Cor. 13:13; Rev.1:4).

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.

Our title at the head of this paper is one such. Yet there is abundance of teaching in the Holy Scriptures that God reveals Himself as Father, Son and Holy Spirit, not three Gods, but a Triune God, though Scripture teaches that the Father is God, the Son is God, the Holy Spirit is God, yet one God indivisible.

Scripture is most plain, whatever unbelief may say, that there are three distinct persons in the Godhead, equal in power, majesty, and glory, each taking His own part in all that is done, whether in creation or redemption, yet ever acting in perfect unity and communion.

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.

C.C. — Yes; that is another line. It is a different word. Now, if there are persons in the Godhead, and yet the Godhead is a unity, in what sense or senses are the three persons one? They are one in substance; one in nature; one in life; one in purpose, plan and counsel.

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).
