What is the Father in the Holy Trinity?

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

God the Father. As we have just said, it is the Father's name which is ever upon our Lord's lips, and this does not mean merely the relationship of God to the Lord Jesus as we speak of His relationship to ourselves, but it means specifically the first person of the Trinity revealed as Father, the One who declares His good pleasure in His Son.

When this Visitor from heaven was baptized by John the Baptist, the Holy Spirit descended and abode upon Him (John 1:32), and a voice from heaven said, "This is My beloved Son" (Matt. 3:17). Thus God is revealed to be Father, Son and Holy Spirit — relationships which were not revealed and therefore not understood before. Our Lord, however, constantly speaks of "the Father" and addressed Him as "My Father." He speaks of Him as One who has already been declared as the Father (see Matt. 11:25-26; Mark 13:32; Luke 9:26; John 4:23; 5:20, and many other places).

This was revealed at the baptism of the Lord Jesus. The Holy Spirit descended “like a dove” and abode upon Him; and God the Father declared “This is My beloved Son in whom I am well pleased.” That the Father is a distinct Person and is God is plainly stated, as in John 20:17.

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.

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.

To God the Father belongs initiative. All purpose, counsel, direction, are His. To God the Son belongs administration — the execution of the Divine purpose whether in creation, redemption, or judgment. To God the Holy Ghost belongs the energy all-pervading that, acting always in perfect harmony with the Father's counsels and the Son's administration, produces the desired effects whether upon matter in creation, or upon the souls and ultimately the bodies of saints in connection with redemption.

In Matthew 28:19 we have the risen Lord conferring authority upon his disciples to baptize. He authorizes them to baptize “to (eis) the name of the Father, and of the Son, and of the Holy Ghost.” This is the only place where the authorization is mentioned. The authority for Christian baptism is found here, and here alone. The risen Lord in issuing a commission to the eleven to go and disciple all the nations, authorizes them to formally identify the disciples of Christ with the confession of “the name of the Father, and the Son, and the Holy Ghost.” It is thus plain that baptism is a token, or mark, or badge, of discipleship to Christ. The badge of discipleship is put on by the baptism. The baptism signifies that the one baptized is connected with the profession of “the name of the Father, and the Son, and the Holy Ghost.” Hence the formula “to,” (or “unto”) the name, and so forth.

How, then, it may be asked, do we sustain our doctrine of eternal generation and at the same time obviate such a conclusion? We sustain it thus. We have already shown that there is a distinction between the Essence of God, which is one and self-existent, and the Personality of the Three Persons in the Godhead. Which is threefold, and thus intercommunicative, and so far dependent. We have to lament the inadequacy of language, or at least of our own language, to set such sublime mysteries forth; but the doctrine of a Trinity in Unity can only be so defended. The Unity of God implies self-existence; the Trinity in Unity implies relationship. Thus as regards the Unity of Essence Christ is self-existent; but as regards the Trinity He is begotten. He is therefore not a begotten God, though He is a begotten-Son. This explanation may be called mystical and obscure; but on such deep and incomprehensible subjects all thought fails and all language falters. Yet as we are sometimes called upon to state or defend our views of divine truth, it is desirable to have clear views of what we believe, and to express them as plainly as possible. We believe, then, that there are Three Persons in the Godhead, and that these are distinguished from each other by certain personal relationships, and that these personal relationships are not covenant titles, names, or offices, but are distinctive and eternal modes of existence. We are thus preserved from Sabellianism on the one hand, which holds that there is but one God with three different names; and Tritheism on the other, which makes three distinct Gods. But believing in a Trinity of Persons, in the Unity of the divine Essence, we say that the father is a Father as begetting; the Son is a Son as begotten; the Holy Spirit is a Spirit as proceeding. If, as imputed to us, we were to say that the Son is “a begotten God,” we should deny Him self-existence in His Essence, as One with the Father and the Holy Spirit; as if we should say that He is a Son by office or by His incarnation, we should deny, as Mr. Crowther does, His true, proper and actual Sonship. To sum up the whole in a few words, it is in His Person, not in His Essence, that He is the only-begotten Son of God. Dr. Gill has opened up this distinction with his usual clearness and ability in the following extract from his “Body of Divinity”:

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.

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.
