Many Christians are at a loss to understand, much less to defend, the "Trinity." Critics argue that that word is not even found in the Bible. To deal with that issue, we must begin with God, as the Bible itself does. There are two general concepts of God: (1) pantheism/naturalism, that the universe itself is God; and (2) supernaturalism, that the Creator is distinct from His creation. Within these are two more opposing views: (1) polytheism, that there are many gods; and (2) monotheism, that there is only one true God.
Monotheism itself is divided into two rival beliefs: (1) that God is a single being; and (2) that God has always existed in three Persons who are separate and distinct yet One. Obviously, Christians are the only ones who hold the latter view—and even some who call themselves Christians reject it. Yet it is the only logically and philosophically coherent view of God possible.
Pantheism has the same fatal flaws as atheism. If everything is God, to be God has lost all meaning and so nothing is God. The problems with polytheism are equally obvious. There is no real God who is in charge, so the many gods fight wars and steal one another's wives. There's no basis for morals, truth or peace in heaven or earth. Polytheism's basic problem is diversity without unity.
The belief that God is a single being is held by both Muslims and Jews, who insist that Allah and Jehovah are single entities. It is also held by pseudo-Christian cults such as the Jehovah's Witnesses and Mormons—and by various aberrant Christian groups who also deny the deity of Christ. Some Pentecostals claim that God is a single being and that Father, Son and Holy Spirit are God's three "titles" or "offices." Here we have unity without diversity.
That God must have both unity and diversity is clear. The Allah of Islam and the Jehovah of Jehovah's Witnesses and Jews, for instance, is incomplete in himself, unable to experience love, fellowship and communion before creating beings with whom he could have these experiences. The Bible says that "God is love." But the God of Islam and Judaism could not be love in and of himself—for whom could he love when he was alone before creation?
This belief that God is a single entity (Unitarianism) and not three Persons existing eternally in one God (Trinitarianism) was first formulated in the early church around A.D. 220. by a Libyan theologian named Sabellius. He attempted to retain biblical language concerning Father, Son and Holy Spirit without acknowledging the triune nature of God. Sabellius claimed that God existed as a single Being who manifested Himself in three activities, modes or aspects: as Father in the creation, as Son in redemption, and as Holy Spirit in prophecy and sanctification. This heresy, though condemned by the vast majority of Christians, survives to this day.
The Bible presents a God who did not need to create any beings to experience love, communion and fellowship. This God is complete in Himself, being three Persons: Father, Son and Holy Spirit, separate and distinct, yet at the same time eternally one God. They loved and communed and fellowshiped with each other and took counsel together before the universe, angels or man were brought into existence. Isaiah "heard the voice of the Lord [in eternity past] saying, "Whom shall I send, and who will go for us?" (Isa:6:8Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me.
See All...). Moses revealed the same counseling together of the Godhead: "And God said, Let us make man in our image, after our likeness"; and again, "Let us go down, and there confound their language" (Gen:1:26And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
See All...;11:7). Who is this "us" if God is a single entity? Why does God say, "The man is become as one of us" (Gen:3:22And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
See All...)?
Moreover, if God is a single Being, then why is the plural Hebrew noun elohim (literally "gods") used for God repeatedly? In fact, this plural noun is in the center of Israel's famous confession of the oneness of God! The Shema declares, "Hear, O Israel, The Lord our God is one Lord" (Deut 6:4; Mk 12:29). In the Hebrew it reads, "Jehovah our elohim [gods] is one [echad] Jehovah." The Hebrew word echad allows for a unity of more than one. For example, it is used in Genesis:2:24Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
See All... where man and woman become one flesh; in Exodus:36:13And he made fifty taches of gold, and coupled the curtains one unto another with the taches: so it became one tabernacle.
See All... when the various parts "became one tabernacle"; in 2 Samuel:2:25And the children of Benjamin gathered themselves together after Abner, and became one troop, and stood on the top of an hill.
See All... when many soldiers "became one troop"; and elsewhere.
Nor is the word elohim the only way in which God's plurality is presented. For example: Psalm:149:2Let Israel rejoice in him that made him: let the children of Zion be joyful in their King.
See All..., "Let Israel rejoice in him that made him" (literally "makers"); Ecclesiastes:12:1Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them;
See All..., "Remember now thy Creator (lit. "creators"); and Isaiah:54:5For thy Maker is thine husband; the LORD of hosts is his name; and thy Redeemer the Holy One of Israel; The God of the whole earth shall he be called.
See All..., "For thy Maker is thine husband (lit. "makers, husbands"). Unitarianism has no explanation for this consistent presentation of God's plurality all through the Old Testament. Although the word "trinity" does not occur in the Bible, the concept is clearly there, providing the unity and diversity which makes possible the love, fellowship and communion within the Godhead. Truly the trinitarian God is love—and He alone.
Jesus said, "The Father loveth the Son and hath given all things into his hand" (Jn:3:35The Father loveth the Son, and hath given all things into his hand.
See All...). God's love is not just toward mankind but first of all among the three Persons of the Godhead. And three Persons they must be. Father, Son and Holy Spirit can't be mere offices, titles or modes in which God manifests Himself, for such cannot love, consult and fellowship together. Not only the Son is presented as a Person, but so are the Father and the Holy Spirit. The Bible presents each as having His own personality: each wills, acts, loves, cares, can be grieved or become angry. "Offices" or "titles" don't do that! Unitarianism isn't biblical—and it robs the Godhead of the necessary qualities of true Deity.
Godhead? Is that a biblical term? Yes, indeed. It occurs three times in the King James New Testament in Acts:17:29Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device.
See All..., Romans:1:20For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
See All..., and Colossians:2:9For in him dwelleth all the fulness of the Godhead bodily.
See All.... In contrast to theos, which is used consistently throughout the New Testament for "God," three different but related Greek words occur in these verses (theios, theiotes, theotes), which the King James translators (here's another reason for preferring the KJV!) carefully designated by the special word, Godhead. That very term indicates a plurality of being. Paul wrote, "In him dwelleth all the fullness of the Godhead bodily" (Col:2:9For in him dwelleth all the fulness of the Godhead bodily.
See All...). Did he simply mean that in Christ dwelt all the fullness of Himself? That would be like saying that in me dwells all the fullness of me. Well, of course it does—so why say it, and what does it really mean? Nothing!
Does it simply mean that in Christ dwells all the fullness of Deity as non-KJV translations render it? That, too, would be redundant—or it would detract from the deity of Christ. For if Christ is intrinsically God, then what is the point of saying that "in Him dwells all the fullness of deity"? Of course it does! But if Christ is the Son and there are two other persons in the Godhead, then it does mean something. It means that just as Father, Son, and Holy Spirit are one God, so when the Son became man He brought that fullness of the Godhead with Him into flesh.
In Romans:1:20For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
See All... Paul argues that God's "eternal power and Godhead" are seen in the creation He made. God's eternal power—but His Godhead? Yes, as Dr. Wood pointed out years ago in The Secret of the Universe, the triune nature of God is stamped on His creation. The cosmos is divided into three: space, matter and time. Each of these is divided into three. Space, for instance, is composed of length, breadth and width, each separate and distinct in itself, yet the three are one. Length, breadth and width are not three spaces, but three dimensions comprising one space. Run enough lines lengthwise and you take in the whole. But so it is with the width and height. Each is separate and distinct, yet each is all of space—just as the Father, Son and Holy Spirit is each God.
Time also is a trinity: past, present and future—two invisible and one visible. Each is separate and distinct, yet each is the whole. Man himself is a triunity of spirit, soul and body, two of which are invisible, one visible. Many more details could be given of the Godhead's triunity reflected in the universe. It can hardly be coincidence.
The Hebrew word elohim (gods) occurs about 2,500 times in the Old Testament, while the singular form occurs only250 times and most of those designate false gods. Genesis:1:1In the beginning God created the heaven and the earth.
See All... reads, "In the beginning, elohim created the heaven and the earth"; i.e., literally, "gods created the heaven and the earth." Though a single noun is available, yet the plural form is consistently used for God. And in violation of grammatical rules, with few exceptions, singular verbs and pronouns are used with this plural noun. Why?
At the burning bush it was elohim (gods) who spoke to Moses. Yet elohim did not say, "We are that we are," but "I AM THAT I AM" (Ex 3:14). One cannot escape the fact that, all through the Bible, God is presented as a plurality and yet as One, as having both diversity and unity. This is unique among all the world's religions! To reject the Trinity is to reject the God of the Bible.
The New Testament presents three Persons who are distinct, yet each is recognized as God. At the same time we have repeatedly the clear statement that there is only one true God. Christ prays to the Father. Is He praying to Himself? "The Father sent the Son to be the Saviour of the world" (1 Jn:4:14And we have seen and do testify that the Father sent the Son to be the Saviour of the world.
See All...). Did He send Himself? Worse yet, did one "office" pray to and send a "title"? Father, Son and Holy Spirit each has distinct functions, yet each works only in conjunction with the others. Christ said, "The words that I speak unto you I speak not of myself [on my own initiative]: but the Father that dwelleth in me, he doeth the works" (Jn:14:10Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
See All...); "I will pray the Father, and he shall give you another comforter...even the Spirit of truth" (Jn:14:16-17 [16] And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
[17] Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
See All...). Throughout the New Testament, Father, Son and Holy Spirit are each separately honored and act as God, yet only in concert with one another.
The Old Testament also presents three Persons in the Godhead interacting. For example: "Hearken unto me, O Jacob and Israel, my called; I am he; I am the first, I also am the last. Mine hand also hath laid the foundation of the earth, and my right hand hath spanned the heavens....From the time that it was, there am I: and now the Lord God, and his Spirit, hath sent me" (Isa:48:12-16 [12] Hearken unto me, O Jacob and Israel, my called; I am he; I am the first, I also am the last.
[13] Mine hand also hath laid the foundation of the earth, and my right hand hath spanned the heavens: when I call unto them, they stand up together.
[14] All ye, assemble yourselves, and hear; which among them hath declared these things? The LORD hath loved him: he will do his pleasure on Babylon, and his arm shall be on the Chaldeans.
[15] I, even I, have spoken; yea, I have called him: I have brought him, and he shall make his way prosperous.
[16] Come ye near unto me, hear ye this; I have not spoken in secret from the beginning; from the time that it was, there am I: and now the Lord GOD, and his Spirit, hath sent me.
See All...). The One speaking through Isaiah refers to Himself as "the first and the last" and the Creator of all, so He must be God. But He speaks of two others in the same passage who must also be God: "the Lord God, and his Spirit, hath sent me." Jesus presented a similar passage to the Pharisees (Mat:22:41-46 [41] While the Pharisees were gathered together, Jesus asked them,
[42] Saying, What think ye of Christ? whose son is he? They say unto him, The son of David.
[43] He saith unto them, How then doth David in spirit call him Lord, saying,
[44] The LORD said unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool?
[45] If David then call him Lord, how is he his son?
[46] And no man was able to answer him a word, neither durst any man from that day forth ask him any more questions.
See All...) when He asked them who the Messiah was, and they said, "The Son of David." He then quoted, "The Lord said unto my Lord, sit thou on my right hand, till I make thine enemies thy footstool" (Ps:110:1(A Psalm of David.) The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool.
See All...). Then Jesus asked them, "If David then call him Lord, how is he his son?" The Pharisees were speechless. Unitarianism cannot explain these two "Lords."
It is a mystery how God can exist in three Persons yet be one God; but it is also a mystery how God could have no beginning and create everything out of nothing. We can't understand what a human soul or spirit is. Nor can we explain love or beauty or justice. It is beyond human capacity to comprehend the full nature of God's being. But neither can we understand what it means for us or anything else to exist—nor can we comprehend what space is or what time is or matter is. For every door science opens, there are ten more unopened doors on the other side. The more we learn, the more rapidly the unknown expands before us like receding images in a hall of mirrors. The Jehovah's Witnesses and other Unitarians argue that because the Trinity can't be understood it can't be. But the fact that it is beyond human comprehension is no reason for rejecting what the Bible so consistently presents to us. God is telling us about Himself so we can believe in and know Him. We dare not reject what He says or lower it to the level of our finite minds. TBC
