Q: If the Word Trinity isn’t Even Found in the Bible, Why Do Christians Believe in it?


The word Trinity isn’t found in the bible but that doesn’t mean the concept isn’t. The concept of the trinity is complex and it’s explanatory scope and power are the foundation for a coherent understanding of who God claims Himself to be. In this article I would like to compare the Old and New Testaments claims about God and see if the concept of the Trinity is affirmed or denied in scripture. The very concept of God is a complex one and I don’t think that mankind can understand and determine exactly who and what God is, other than what God has chosen to reveal to mankind about himself, in scripture.

What is the definition of the Trinity? The word Trinity simply means: three persons in one being, God the Father, God the Son (Jesus) and God the Holy Spirit, also called the Godhead. Let me explain how this is possible. Note, however, that I can’t give any direct illustrations because no naturalistic example could explain the greatest conceivable being (God), who is not bound by time, space, or matter.

Scripture tells us that God has entered into the world many times. Adam walked with God in the garden1. God appears to Abraham2. Jacob wrestled with God3. These accounts are only from he first few chapters of the Old Testament. Now that we have established that God has come into the world lets look at some possible difficulties with this understanding. Scripture says that “no one has seen God”4 and that “no one can see God and live”5. Is this a blatant contradiction in scripture? I think the concept of the trinity reconciles such verses once it is possible that more than one person exists in the Godhead6. This concept of “personhood” is used to describe the three persons of the Godhead because the word “person” is appropriate.  A person is self-aware, can speak, love, hate, say “you,” “yours,” “me,” “mine,” etc. Each of the three persons in the Trinity demonstrates these qualities7. Also consider that personhood is not tied to a physical body or state but is geared toward a mind. Many people have suffered the loss of a limb or even the loss of brain tissue, but that does not retract from their personhood because persons are directly related to their minds.

The questions of who and what become beneficial to identify the essence and nature of God. Lets apply those questions to ourselves; what am I? I am a human being. Who am I? I am Petrus Klopper, the person. This illustrates that I am one in being and one in person, though my being and person are different. When applying these questions to God, we see that it is possible for God to have a being, distinct from his personhood.

God the Father8, Jesus the Son9 and the Holy Spirit10 exist in perfect harmony with equal power, throughout eternity as the Godhead. Jesus exists as one person with two natures, a divine nature and a human nature. This is called the Hypostatic Union of Jesus, among theologians today11. Any other arrangement in the Godhead is a departure from Christianity. The Holy Spirit is not a force and Jesus is not simply human in nature as the Jehovah’s Witnesses hold. Nor is there three God beings in the trinity like Mormons would claim. Nor is there simply one God that changes “modes” and jumps back and forth between God in heaven, Jesus and the Holy Spirit12.

Jesus, being fully man and fully God is capable of entering into the world and communicating face to face with mankind, due to his human nature13. The Trinity is also the best explanation for verses where God is referred to multiple times in different locations in the same context. Lets consider the text in Genesis 19:24 “Then the Lord rained down burning sulfur on Sodom and Gomorrah—from the Lord out of the heavens.”   The text clearly states that two divine figures are interacting together in the same context. Lets also consider Psalm 110 where it is written, The Lord said to my Lord, “Sit in the place of honor at my right hand until I humble your enemies, making them a footstool under your feet.” These are two obvious examples for God interacting with God in a set location and context. And perhaps the best display of the Godhead is at the baptism of Jesus in Mathew 3: 16-17  And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him;  and behold, a voice from heaven said, “This is my beloved Son, with whom I am well pleased.” Hear we see the three separate persons in the Godhead, represented by the text, God the Father speaks from heaven to the “beloved Son” as the Holy Spirit descends upon the Son like a dove. Genesis chapter one also gives us insight into the Godhead, Genesis 1:26 -Then God said (singular verb), ‘Let us make (plural verb) man in our image, after our likeness’14. This verse alone demonstarates the plurality of personhood in the Godhead. Now one might think that this is a grand or royal way of speaking but the truth is that this verse is unique, there simply isn’t another reference of this sort in scripture.

A purely monotheistic God, as worshiped by Jews, Jehovah Witnesses and Muslims, fails to be all loving in his nature, just as one person needs another person to love so God needs something to love if he claims to be “all loving”15. An all loving God only makes sense from the perspective of the Trinity.

We can determine that the concept of the Trinity is confirmed in scripture, and does offer explanatory scope and power regarding who and what God is. We have also seen how the concept of an “all loving” God is consistent with the Trinitarian view of God, who can also come into the world and meet with people -because of Jesus’ human nature and divine nature. God can interact with God in the same context as we see at the baptism of Jesus, in the Psalms and at Sodom and Gomorrah. The deity of Jesus and the deity of the Holy spirit are essential to a coherent understanding of scripture. Therefore, even though the word Trinity is not found in the bible, we have good reasons to believe that the concept of the Trinity is sound; and by the way, the word “bible” also isn’t found in the bible either.

  1. The concept of Trinity is a church construct.

    Arianism and semi-Arianism are testimony to the fractious beliefs that surrounded the nature of the biblical character, Jesus of Nazareth; a doctrine that took three hundred years to appear. And was not officially settled even then.

    It took some seriously bloody conflicts and the death of a great many Christians as a precursor to Constantinople in 381 ( almost 60 years after Nicea) when Theodosius (who only became a Christian about a year before he convened this council) made it law and thus the fun and games to rout out all ”heretical” beleifs could begin.

    So the truth about the Trinity is simple:
    The Church made it up.


    1. Hello Arkenaten,
      The Deity of Jesus is only the most disputed doctrine therefore I’m not surprised at your objection. The timeline is irrelevant if it’s true. You are entitled to your opinion because Paul is part of the church. He had a personal encounter with Jesus as well as being a highly educated Pharisee. The Trinity has far greater explanatory scope and power concerning the scriptures about God the Father, the Holy Spirit and with regards to Jesus. Hope that clarifies. 🙂


      1. It clarifies a theological motif but history is quite clear on the issue – this was the reason there was so much dispute surrounding the Trinity issue.
        If this were not the case, as you appear to be asserting, can you explain the reason for the centuries long disputes and the horrendous bloodshed over this issue? Disputes that continued even after it was written into law at the command of Theodosius?
        And to which there is still no agreement among all christian sect event t this day?


        1. I’m by no means trying to oversimplify the issue. The conflicts show how serious the convictions were from both parties. That’s a historical reality, now both positions regarding the conflict can be wrong if you consider the law of non-contradiction but only one has the possibility of being correct. Do I think that the conflict was a reflection of Jesus words? No. The reality is this is a complex issue and because a counterfeit exists that doesn’t nullify the true currency. Hope that helps


          1. The conflict demonstrates that there is no ”history” of the Trinity, which was simply a claim made; quite likely by Athanasius, who’s view was a minority view in any case.
            There is no biblical evidence f the Trinity and Jesus himself never professed he was god either.
            If this were the case there would have been no disputation from the word go.
            And because of the politics surrounding this surrounding this issue which threatened to establish the Empire, Constantine sought and end to the fighting. Constantine eventually accepted the Athanasius view and forged ahead.
            It is not a complex issue at all. The nly complexity is the fact that christians refuse to accept the historical veracity, largely because most are ignorant of the history of their own religion and thus merely accept what they have been brought up with.
            The facts are really quite straightforward.
            The decision was simply a political one ( Constantine could really have not cared a fig about christianity, he was merely trying to maintain his position).
            There is not a scrap of evidence to support any claim of a biblical trinity.
            To state otherwise suggests a somewhat close-minded attitude toward the true historical nature of the christian religion.
            I reiterate. The church simply made it up, and thanks to Theodosius, wrote it into law and then proceeded to try liquidate all opposition. That is a matter of historical record.


  2. I have been talking to several Jehovahs Witnesses recently and this is the topic we talked about last week. Their argument against the Trinity is that 1) The Trinity is never explicitly mentioned in the bible.
    2) The Trinity first became accepted by the Church after the Council of Nicea which was heavily influenced by Constantine who wasn’t a true Christian.
    My counter-argument was that 1 is true and obvious because it was a name given to a doctrine that was evident in the Old and New Testament but not referred to as the “Trinity” until later. I think your blog gives some great examples of this.
    I also countered that early church fathers had believed this doctrine even if it wasn’t specifically called the Trinity. After they left I looked up some specific quotes from pre Nicean church fathers. Here is one website I found that does a nice job of putting these together: http://thecripplegate.com/did-the-early-church-affirm-jesus-deity/
