What is the Trinity made up of?

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).

The Holy Ghost is a separate Personality in God. His Name is seen in conjunction with the names of the Father, and the Son, in Matthew 28 Christian baptism commits one to the confession of God as revealed by Christ, the full revelation of the one true living God being Father, Son, and Holy Ghost. There are not two Gods, or three Gods, as ignorant objectors allege; but three Personalities in one God. These three ever subsisted in the Godhead; and with regard to the Holy Spirit, He is expressly called the Eternal Spirit (Heb. 9:14). Before the worlds were made, God is (Heb. 11:3, 6); but even when heaven and earth were created these material things were not capable of bringing to light all that God is. Moreover, though Enoch and Noah walked with God, and Abraham was called God's friend, and the lord spake face to face unto Moses as a man speaks to his friend, their great intimacies did not bring to light the full truth. He was known to the patriarchs under His name of Almighty God, for the attribute of All-might pertains to the whole Godhead. Later, an advance was made when God especially linked His name of Jehovah with the nation of Israel (Exodus 6:2-3), for eternal existence and unchangeable glory (which are implied in that name) belong equally to the whole Godhead. Yet amid all the glories unfolded by the prophets, the Godhead secret w as never fully disclosed until in the fulness of time Christ came When it was no longer a question of the creation of worlds, or of the power that could sustain faith and reward it, as in Old Testament times, but rather of making purgation of sin and of revealing all that God is, the appearance of the Son of God in a concrete human form, apart from sin, necessarily brought to light His relations with the other Persons in the Trinity. Christianity therefore is based upon the knowledge of God as Father, Son, and Holy Ghost.

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.

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.

This clearly shows that whilst Scripture affirms that there are three distinct Persons in the Godhead, yet there are not three Gods, but one; not a trinity of Gods, but a triune God.

Divine revelation tells us of a triune God, that is three Divine Persons yet One God. The Bible presents three in One and One in Three—Father, Son and Spirit, the Triune God, completely One in power, will, and knowledge.

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.

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.

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.

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.
