My Conversion from Unitarianism to the Trinity

Not that my testimony proves anything, but I share it here to dispel the idea that seems to be common among Unitarians, that Trinitarians are just slaves to tradition, that if you just show the truth to all these uninformed Trinitarians, they will see the light and change. There are plenty of us who were raised to reject the Trinity who converted due to a study of the Scriptures.

So, I’d like to explain just how it is that a Unitarian comes to believe in the Trinity. This is a personal story of the Scriptures that revealed to me that I was wrong to reject the Trinity as unbiblical. Nothing short of a biblical case would have convinced me.

It’s hard to say exactly when things started to change, but I know it was sometime in the year after I graduated high school. The internet was a fairly new thing, only a few years old, and I had spent the previous year researching all I could about various religions. I had been raised in the Way International, but my parents had left the group when I was younger, like many others. But also like many others, my family and I had held onto the theology of the group we left behind and gathered with others in the same situation in homes and kept things going. In high school, I became very interested in arguing with my Trinitarian friends and with people online in chat rooms and on message boards, challenging their “traditions” of holding to the Trinity because of creeds and the influence of pagans. I went for hours at times with my peers, and most were not able to mount any kind of strong defense. Not that I convinced anyone that I’m aware of, but both sides remained steadfast in their previous convictions.

I knew all the prooftexts: the Father is “the only true God”, Jesus said the Father is “greater than I”, and it was just obvious to me that if there is just one difference between things, those things cannot be one thing. Jesus was tempted, God cannot be tempted. Jesus didn’t know the day or hour of His return, God knows everything. And of course it just seemed obvious to me that someone’s son cannot be himself, so there’s no way Jesus could be called the Son of God and be God at the same time. It all was so preposterous, I thought it impossible that any Trinitarian who actually looked at the Scriptures carefully could possibly still believe that Jesus is God or that there is this whole thing called the Trinity.

My last year of high school, I branched out and studied other faiths in order to engage them with the truth, looking into Mormonism, Islam, Hinduism, Roman Catholicism, etc. When I came across the Jehovah’s Witnesses, though, I ran into something unexpected. The primary area of disagreement with them from Protestant Christianity was on the doctrine of the Trinity and the Deity of Christ. Now, my own theology from the Way didn’t look much like the Jehovah’s Witnesses, but the line of argumentation taken by Christians was aimed directly at proving that Jesus is God.

This didn’t bother me at first, of course, since I had been inoculated well against most of the standard prooftexts leaned on by Trinitarians, and found those arguments unconvincing. But it became a little uncomfortable reading people I had come to trust were committed to basing their beliefs on the Bible going straight to the Bible with passion to defend the Trinity. That discomfort led me away from studying Jehovah’s Witnesses for a while. It was just a little too uncomfortable.

After some time, though, I felt a sense of moral unease. I knew that I was avoiding uncomfortable arguments, and I knew this couldn’t be okay. If what I believed was true, it should be able to stand up to scrutiny. Surely, if Jesus were not God, no amount of sophisticated argument would make it so. And, I had to admit, if somehow I was wrong, I would want to know it. I was still thoroughly convinced against the Trinity, but I knew that I am only human and could be wrong. I set out to learn, trusting God to lead me to the truth. And so I began to study in earnest.

At first, it was not difficult to find answers that were satisfactory against the arguments being made for the Trinity. There are some standard texts that Trinitarians go to first, and I knew ways to reinterpret them to avoid the Trinitarian conclusion. After a while, though, the sheer weight of texts, including many that I had no consistent answers for, began to shift my perspective.

I remember three questions, related to the Scriptures, that opened the door to my conversion. First, I was unclear as to whether I was supposed to worship Jesus. I saw that He was worshiped repeatedly in Matthew, but then He made clear, also in Matthew, that we are not to worship anyone but God (Matt. 4:10). So if Jesus isn’t God, are we supposed to worship Him? I didn’t have a good answer to this question.

Second, I saw that the Old Testament doesn’t just teach that Yahweh is the only God, but also that He is the only Savior (Isa. 43:11, 45:21). If we take Jesus to be the Savior of the world, the only way that works is if He is and has always been Yahweh.

Third, I could not explain away all of the very clear references to Jesus as Creator. It’s not just one or two places. Jesus is creator in so many texts, but the first one that I couldn’t find a way around was Colossians 1:16. I tried to get around John 1 by saying that the Word is just the expressed plan of God and that certain parts of the prologue, which are undeniably about a person, were about the Father, but I couldn’t do that in Colossians and remain consistent in the text. It was because of this text and others like it that I spent a little of my time while transitioning from Unitarianism to Trinitarianism as someone who basically believed in Arianism. I thought maybe Jesus was creator but still separate and inferior to God. Eventually, though, I couldn’t deny that everything pointed to full deity for the Son. The Scriptures simply lacked a category for a lesser being as Creator.

In concert with the Scriptures I was seeing, I also, for the first time, began to understand just what the Trinity actually was, according to Trinitarians who knew. I had spent a lot of time talking about how the Trinity clearly denies all the texts that say there is only one God, or how Jesus had human limitations, so obviously isn’t God. What I began to do was actually listen to Trinitarian apologists who engage arguments like mine. I let them define their own theology, and I found that virtually all of my favorite arguments were based on misrepresentations of the Trinity. When I allowed that, in its most basic form, the Trinity is actually not just a single doctrine, but a collection of simpler teachings that, when all affirmed, just are the Trinity, I found I had little reason anymore to deny it.

The doctrines I am speaking of are

1. There is only one God.

2. The Father, Son, and Holy Spirit are distinct Persons.

3. The Father, Son, and Holy Spirit are each affirmed to be God.

Later, I would tackle the two natures of Christ. I understood at this point that the Trinity doctrine was composed of parts. This was huge, because, by this time, I had seen how the parts of the Trinity were found in Scripture. Sure, I disagreed with Trinitarians on their interpretation of those passages, but I at least understood where they were coming from. They were saying that all the parts of the Trinity are there in plain text and that they don’t need more than that. Combine that with a few explanations to how God can be three in one sense while being one in another sense, and that Jesus has two natures, God and man, and this is why He can have attributes of both God and man, and you have a self-consistent, and, on its face, biblical theology.

At this point, I knew that the only way to prove my Unitarianism was right and the Trinity wrong was to show that it explicitly contradicted the Scriptures, but the more I studied, the less confident I became that the Trinity was unbiblical. Every passage I appealed to was shown to already have been considered and incorporated into the Trinity. While I could interpret passages in non-Trinitarian ways, I could find no Scripture that must be interpreted as denying the Trinity.

My last line of defense was the historical argument. I was still pretty well convinced that the Trinity, and specifically the deity of Christ, was invented centuries after Christ. How I was able to hold in my head both that the Trinity was biblical, yet untrue because it came later than the Bible, I don’t know. It wasn’t long that I held this view though. A few months at most. All it took was looking into what was written by the earliest Christians that we have and I knew I had been misled to think they didn’t believe Jesus is God. They most certainly did. Views may have differed somewhat, but Jesus’ deity was there from as far back as we can go.

From that point on, I’ve been a Trinitarian. Time and study have refined my views, but only strengthened my belief that God did indeed reveal Himself to be a Trinity and that the basic truths that make up the doctrine have always been believed in the church.

One of the first things that changed was that I had the very strong desire to go to church and spend time with Christians. This was a curious desire because I had always thought of this issue as one that should not divide Christians. I thought a person who believed in Jesus, whether they believed He is God or not, was saved either way. This was not based on Scripture or reason, only what I’d been told.

Logically, I think that there is no way that people on both sides of that issue can be saved. If the Unitarian is right, then the Trinitarian is worshiping Jesus as God, when He isn’t. That is idolatry, and persisting in it is unbelief. If the Trinitarian is right, then anyone who refuses to bow the knee to Jesus and worship Him as such is basically telling God, “You’re not God.” I don’t think a person needs to understand everything about the Trinity to be saved, but I don’t see how someone can get wrong who Jesus is at this point and still be in possession of the faith.

I pray this has been helpful to you, and that the Spirit would use it to guide you into the truth.

2 thoughts on “My Conversion from Unitarianism to the Trinity”

  1. This is fascinating, as it is the exact opposite path that my journey has taken. I was raised in a non-denominational Christian household. In high school, I started attending a Bible church in the same theological camp as John MacArthur. In college, I went to a conservative Presbyterian church, then came back to that Bible church. When I started my current job two states away from home, I church-hopped a bit. First it was another Bible church, then a Baptist church. Something in my soul wasn’t satisfied with any of the places I visited.

    About that time, a Messianic (Torah-observant gentile) friend at work started sharing her faith perspective with me. I went from thinking she was a crazy legalist to realizing how wrong I’d been as I began studying more on my own. I was shocked at how much I didn’t know I didn’t know about the Scriptures and the faith of our fathers. I began soaking up information like a sponge.

    Now I can’t say when exactly I began questioning the Trinity, but a few months before all of this happened, I’d befriended a homeless guy in the city. I worked part-time for a restaurant delivery service similar to Grubhub, and this guy sat outside the ever-popular Chipotle near the university. One night, we got to talking about faith, and I shared the Gospel (as I understood it at the time) with him. I knew it was necessary to believe in the Trinity to be saved, but as I explained it to him, I realized I never would’ve believed someone else saying those things to me. It disturbed me because this was something you couldn’t challenge. I let it go.

    Fast forward to after my conversation with the Messianic, and one of the first resources I discovered was the United Church of God. As I was devouring their publications, I came across their booklet on the Trinity. As I read it, two things stood out to me: (1) It is not a taboo to question the doctrine of the Trinity, and (2) Christians who were so biblically knowledgeable on other things my pastors had never told me (and probably didn’t know themselves) were not Trinitarian. That was a game-changer for me.

    I attended a UCG fellowship a couple of times, but ultimately decided to go to my friend’s Sabbath fellowship instead. There was a period of time where I was basically an Arian, partly because of the UCG’s binitarian theology and partly because of my study into the Logos/Memra from the Aramaic Targumim. There were a few things that caused me to abandon the Trinity:

    1. I’m an intellectual and have spent long hours trying to understand the Trinity, but every time I thought I’d arrived at a satisfying explanation, my pastor smiled and said it was some sort of heresy. That was frustrating. How can I believe in something that is logically impossible to conceive of? If Man is created in the image of God, why hasn’t God given Man the mental capacity to comprehend 3=1?

    2. The Bible Project on YouTube made an excellent video on the meaning of “spirit” in Hebrew and Greek. While they themselves are Trinitarians, that was my first exposure to the idea that “spirit” doesn’t describe a substance but rather the effect something invisible has on a substance. How could the Spirit of God be a person when the same word could be translated as “Breath” of God and mean the same thing? Simultaneously, just like Jews today call God “haShem” (the Name), it became apparent that in NT times they sometimes called him “the Holy Spirit”. This explained all those times when NT authors casually flipped between “God” and “Holy Spirit” without anyone batting an eye.

    3. Jesus has a God, and clearly said so multiple times. At this point in my walk, I wasn’t settled on whether Jesus _was_ a god of some sort, but even if he was, he still submitted to a God, Yahweh.

    While all of this was in my head, I was also digging deeper into studying the Torah, the Gospel of the Kingdom, and trying to understand the Atonement of Christ. Specifically, I was hung up on the OT’s insistence that everyone repent and obey the commandments of God, while the NT supposedly taught that this was impossible. It seemed cruel that God would ask his chosen people to obey rules he knew they couldn’t obey just so he could sacrifice his son to save them from the punishment brought on by their disobedience to his impossible standards. (This was about the time I started believing in Conditional Immortality/Annihilationism, but that’s ancillary.) If the OT taught that we should repent and obey, and the NT was an addition to the OT but not contradicting it, then there was a big problem. The Bible never says that it is impossible for a man to obey God’s commands, so there is no need for God himself to become a man to obey them for us. This was a bombshell for me. The whole _need_ for a divine sacrifice was rooted in Augustinian Total Depravity, something I could find very little support for in the pages of Scripture.

    I was still hung up on a few key passages that seemed to clearly state that Jesus at least existed before being conceived in Mary. These were predominantly the “creator” passages. I didn’t know how to answer certain verses and was still in a fuzzy gray area between Arianism and Unitarianism. Then Bill Schlegel got fired from The Masters University for announcing his newfound unitarian beliefs. I saw how disgracefully they treated him. But more than that, I had long respected that university because my home church of over a decade praised TMU, and I had several friends who’d graduated from that school. I decided that if anyone could prove to me the divinity of Christ, it was TMU. (This was back in March 2018, for reference.)

    I began tackling the first of the three essays they published defending the deity of Christ. It took over a month, and by the end, I’d written nearly 40 pages of rebuttal and footnotes. I didn’t go into it trying to disprove it, but I figured everything they said needed to be open to scrutiny, so I didn’t hold back. What I found were mostly arguments so weak that it made me angry. How could I have believed in the Trinity for my entire life when it was built on such flimsy arguments. TMU’s essay defending the deity of Christ was the very thing that convinced he wasn’t divine.

    Since that time, I’ve discovered the fascinating work of Dr. Michael Heiser on the Unseen Realm. Although he’s a Trinitarian, everything he says about the Unseen Realm fits perfectly into my evolving conception of the Gospel. I’ve only just begun this most important study, but I do know one thing: I can never go back to the Trinity.


    1. I will say, in post-script, that my respect and reverence for Jesus inversely corresponds to my Christology. When I had a high Christology, I was grateful for what He (God the Son) did, but it was altogether unrelatable to me because Jesus suffered for three days in hell to atone for millions of people’s eternal damnation. That clearly required an infinite God, but when it came to relating to anything he did, it was meaningless to me. I pretty much just ignored all the calls to “walk as he walked” because such a thing was impossible.

      Now, as my Christology has lowered to that of a “mere man” (actually, the Prophet and Anointed King who is the focal-point of Scripture, but “mere” compared with being God), my respect and reverence for him have reached a level I never knew before. I’m within a few months of how old Jesus was when he began his ministry. Knowing all of my struggles with the flesh and the fear of man, I cannot fathom doing what he did or even being able to abstain from sin. I mean, he was tempted in all things yet without sin! I’ve struggled with the common temptations of men for over half my life. I can’t imagine the teenage Jesus being able to overcome thoughts of lust as soon as they entered his head, but by faith in God he did. O, that I had such faith!

      The apostle Paul beat his flesh into submission. Was it such a struggle for Jesus, or did he have such a habit of trusting his Father that he wasn’t even tantalized by temptation? I don’t know. But on the one hand, I can look at his life and see how far I am from perfection, while on the other hand, I can look at his life and see that there is hope for all who trust in God.
