Two Kinds of Unity
What Sets Biblical Oneness Apart
A Note Before Starting
This isn't a document about people. It's about comparing two theological pictures of unity — one built on submission to a single, undivided will, and one built on relationship between distinct Persons who are perfectly one. The goal is to see clearly what makes biblical oneness different, not to characterize anyone made in God's image. Every person, whatever they believe, is someone God loves and is calling toward Himself.
Unity as Submission to One
Islamic theology centers on tawhid — the absolute, indivisible oneness of God. Allah has no partners, no Son, no plurality of Persons within Him. Unity, in that framework, is achieved through total submission — the word Islam itself means submission — of every believer to that single, undivided will. It's a real and serious kind of unity: one God, one law, one community bound together by shared obedience.
What it doesn't include is relationship within God Himself. There's no Father loving a Son, no Spirit proceeding in love between them, because there's no plurality inside the one at all. Unity is horizontal — believers united to each other under God — rather than something modeled first inside God's own nature.
Unity as Relationship Within God
Biblical oneness starts somewhere different. Before it's ever a command for believers, it's a description of who God already is — Father, Son, and Spirit, distinct Persons, perfectly one.
Hear, O Israel: The Lord our God, the Lord is one. (Deuteronomy 6:4)
I and the Father are one. (John 10:30)
Do you not believe that I am in the Father and the Father is in me? (John 14:10)
That's not a contradiction of God's oneness — it's what makes His oneness relational rather than merely numerical. The unity isn't achieved by submission alone; it flows out of love that already exists inside God, and it's that same love that gets extended to believers.
That they may all be one, just as you, Father, are in me, and I in you, that they also may be in us... I in them and you in me, that they may become perfectly one. (John 17:21-23)
Why the Difference Matters
A unity built on submission to an undivided will tends to produce uniformity — one law applied evenly, with little room for relationship to shape it. A unity built on love between Persons produces something else: a call into relationship, not just obedience. That's why the New Testament can describe the church as a body with many different parts, each one different, all genuinely one — because the model it's drawing from is a Trinity of distinct Persons in perfect love, not a single will imposed on many.
For as in one body we have many members, and the members do not all have the same function, so we, though many, are one body in Christ. (Romans 12:4-5)
Submission has its place in the Christian life too — but it's submission that flows out of being loved first, not submission that creates the unity by itself.
For the Harvest
This distinction matters because Romans 11 points to a day when the fullness of the Gentiles comes in — and that includes people currently living under a different picture of unity than the one Scripture offers. Iran and the wider Middle East are, right now, seeing unprecedented openness to the gospel. Understanding what makes biblical oneness different isn't about winning an argument. It's about being able to explain, clearly and with love, why the relationship God offers is better than submission alone — because it's rooted in a Father who already loved a Son before the world began, and who invites every person, from every background, into that same love.
For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. (John 3:16)
