If you ask the question: “how can Christians foster unity in the body of Christ?”, you can get a quick answer which says that Biblical unity in the body of Christ is built on:
- returning personally to Christ as the sole foundation -not denomination, not doctrine as a tribal identity;
- prioritising the one Gospel in evangelism over micro-denominational competition;
- personal, Holy Spirit-led study of Scripture rather than secondhand, tradition-only faith;
- the supreme rule of love which demands commitment to one another despite differences on secondary matters;
- Honouring the diversity of graces and ministries as complementary rather than competitive;
- understanding the critical difference between essential doctrines (non-negotiable) and secondary matters (where diversity is legitimate).
Introduction: Can a Body Be Divided and Still Be a Body?
Dear body of Christ, can a body be divided and still be a Body?
Unity is a state - one defined by being an undivided entity. Is this what the body of Christ is today? During the days of the Apostle Paul, there was a dissension that arose amongst the Corinthians concerning which faction they each belonged to. Paul, learning of this, used it as an opportunity to explain the beautiful open mystery of Unity.
“I appeal to you, brothers and sisters, in the name of our Lord Jesus Christ, that all of you agree with one another in what you say and that there be no divisions among you, but that you be perfectly united in mind and thought.” - 1 Corinthians 1:10 (NIV)
This lesson is very much needed today.
There are multiple factions that exist inside the Body of Christ. Every freedom and grace we have has been interpreted to mean different things by different people. There is also the division of doctrine. While doctrine is not evil and can build grace and faith, we have forgotten the foundation and uniting factor, which is the work of Christ, and have instead embraced our doctrines and man-made traditions as primary. This has led to a major crisis in the body of Christ, where instead of taking the light of Christ to the world, we argue with each other concerning who is right in the interpretation of the Scriptures and mysteries of Christ.
What was purposed to edify now breeds confusion. It is now hard to get every member of Christ to agree to one purpose - leading to a negative outlook of our expensively purchased Faith, and a mediocre spiritual experience as the body.
So how can we find our way back to the place of this divine and powerful unity? The unity that made the Church a highly revered principality and power in the days of the apostles and our fathers?
In this article, we will discuss how we can build, or rather rebuild bridges to foster unity in the body of Christ.
1. What Jesus Prayed: The Foundation of All Christian Unity
Before we discuss strategy, we must begin where Christian unity itself begins - with the prayer that Jesus prayed the night before He was crucified. This is the theological ground beneath every bridge we will discuss.
“I do not ask for these only, but also for those who will believe in me through their word, that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me.” - John 17:20–21 (ESV)
Three things are unmissable in this prayer.
- First: Jesus prayed this specifically for us. Not only for the eleven in the room, but for "those who will believe in me through their word." That means every believer in every century, including the twenty-first. Every divided denomination, every separated congregation, every fractured fellowship is a context in which this prayer is still being interceded.
- Second: The standard is breathtaking. Jesus does not pray that we would get along reasonably well or tolerate each other diplomatically. He prays that we would be one *"as you, Father, are in me, and I in you."* The unity of the Trinity — perfect, unbreakable, loving, differentiated but undivided — is the model. Not human-diplomatic unity. Trinitarian unity.
- Third: The stakes are evangelistic. The reason Jesus gives for wanting His followers to be one is “so that the world may believe that you have sent me.” Our division is not merely a family squabble. It is an evangelistic catastrophe. The watching world looks at the fragmented church and asks, reasonably, why they should follow a gospel whose adherents cannot stand each other.
Christian unity is not a nice-to-have feature for mature churches. It is the evidence the world is waiting to see before it believes.

2. The Critical Distinction: Unity vs. Uniformity
Before we go further, we must establish a distinction that is missing from most conversations about Christian unity and whose absence creates serious theological problems.
Unity is not uniformity.
Uniformity demands that everyone look the same, worship the same way, use the same liturgy, hold identical positions on every theological question, and organise their church in the same structural pattern. Uniformity is impossible in the body of Christ because God designed the body with diversity: “For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ.” - (1 Corinthians 12:12)
The Reformers captured the necessary balance in a phrase that has endured for centuries:
“In necessariis unitas, in dubiis libertas, in omnibus caritas” which means “Unity in necessary things. Liberty in doubtful things. Love in all things.”
This framework provides the map we need. There are essential doctrines where absolute unity is non-negotiable. These essential doctrines are:
- The Trinity - one God in three Persons
- The full deity and full humanity of Jesus Christ
- The bodily resurrection of Christ
- Salvation by grace alone through faith alone in Christ alone
- The authority and sufficiency of Scripture
On these matters, there is no room for "unity through disagreement." They are the foundation, and a foundation does not bend. But there are also secondary matters which are areas where sincere, Bible-believing Christians have disagreed throughout church history without departing from the faith. These include:
- Worship styles and liturgical forms
- Church governance and polity
- Baptismal modes and timing
- Eschatological positions (pre-, mid-, post-tribulation)
- Spiritual gifts and their operation today
- The precise mechanics of prayer and fasting
On secondary matters, the call is not uniformity but love in liberty, holding your own convictions before God while honouring your brother who holds different ones, and refusing to allow those differences to sever the bond of shared foundation in Christ.
Failing to make this distinction produces two equal and opposite errors: the error of treating all doctrinal differences as equally serious (which produces theological indifferentism), and the error of treating all doctrinal differences as equally divisive (which produces ungodly sectarianism). The bridge of unity must be built on truth, not around it.
3. Why the Body of Christ is Divided Today
Understanding the bridges requires understanding what broke them. The divisions in the body of Christ today flow from several identifiable sources:
- The confusion of foundation with structure. When a denomination, theological tradition, or ministry expression becomes the primary identity of its members rather than Christ Himself, the structure has replaced the foundation. A building whose structure becomes its foundation will not stand.
- Secondhand faith: When believers receive their theology entirely from a pastor, a denomination, or a tradition without developing their own Spirit-led engagement with Scripture, they become defenders of a human system rather than followers of a divine Person. Different systems inevitably produce territorial defensiveness.
- The flesh at work in sacred spaces: The New Testament is consistently honest about the fact that pride, jealousy, envy, and the desire for preeminence operate inside the church as well as outside it. Paul addresses factionalism in Corinth (1 Corinthians 1–4), James warns against bitter envy and selfish ambition (James 3:14–16), and Diotrephes who "loves to be first" in 3 John 9 is a portrait of a church leader who used division as a tool of control. The flesh does not check in its ambitions at the church door.
- Doctrinal confusion between the essential and the secondary.** When churches treat secondary matters with the same intensity they should reserve for essential doctrines, they produce a culture where every difference becomes a battle for theological survival. Everything becomes primary. Nothing can be held loosely.
- The competitive model of ministry: When churches are primarily measured by attendance, growth metrics, and cultural visibility rather than by faithfulness to the gospel and love of the brethren — they become competitors rather than collaborators. The market model of ministry is fundamentally incompatible with the body-of-Christ model of the New Testament.
4. Five Bridges to Rebuild: A Practical Biblical Framework
Here are five
Bridge 1: Personal Recognizance of the Foundation of Christ
Before we can bridge gaps, we must individually return to the bedrock of our faith. We must recognise that Jesus Christ - His death, burial, and resurrection - is the sole foundation upon which the Church rests. This is as confirmed in scriptures in 1st Corinthians 3:11 (ESV) which says: “For no one can lay a foundation other than that which is laid, which is Jesus Christ.” Every denominational structure or theological preference is secondary.
When each believer personally anchors their identity strictly in Christ rather than in a specific church label or human leader, the superficial walls that divide us begin to crumble. We must remember that we were bought by the same blood, into the same family, making us inherently one. *"There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus."* (Galatians 3:28)
This is not theological minimalism. It is theological priority. The Apostle Paul, whose letters contain some of the most developed theology in the New Testament, was also the man who said: *"I resolved to know nothing while I was with you except Jesus Christ and him crucified."* (1 Corinthians 2:2). Not because theology doesn't matter — but because the foundation is the non-negotiable thing. Everything else must be built on that, not substituted for it.
**Practical step:** Before your next conversation with a believer from a different denomination or theological tradition, ask yourself: *Do I see this person as a co-heir in Christ, or as a representative of a different team?* The answer to that question will reveal whether your primary identity is in Christ or in a category.
Bridge 2: Evangelism of the One Gospel
**Key Scripture:** *"I am not ashamed of the gospel, because it is the power of God that brings salvation to everyone who believes."* — Romans 1:16 (NIV)
Evangelism and proselytisation are two different things. Evangelism declares Christ to the world. Proselytisation recruits people to your church tradition, theological tribe, or ministry brand. The second produces division. Only the first produces disciples.
Our mission to the world should be a unifying force, not a source of competition. There is only one Gospel: the good news of salvation through Jesus Christ. When the body focuses its energy on preaching Christ and Him crucified to a hurting world, our petty doctrinal disputes lose their weight. True evangelism reminds us that we are all on the same team, fighting for the same souls, under the banner of the same King.
By prioritising the expansion of God's kingdom over our micro-kingdoms, unity becomes an inevitable byproduct.
There is a question that ecumenical pragmatism sometimes asks: "Can we not simply ignore our differences and unite around the mission?" The answer is: not entirely — because if we have different gospels (as Paul warns in Galatians 1:6–9), we have a mission problem, not merely a unity problem. But if what divides us is secondary — worship style, governance, spiritual gift practice — then shared evangelistic mission is both possible and powerfully unifying.
The early Church's unity was not organisational. It was missional. They shared the same story, the same Lord, the same Spirit, and the same mandate. The result was a movement that turned the world upside down (Acts 17:6) without a unified denominational structure.
**Practical step:** Identify one gospel-preaching ministry in your city that worships differently from you. Find one way to collaborate - joint outreach, shared prayer, combined community service - without requiring theological agreement on secondary matters.
Bridge 3: Personal Searching and Understanding of Scripture
**Key Scripture:** *"Now the Berean Jews were of more noble character than those in Thessalonica, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true."* — Acts 17:11 (NIV)
Much of the confusion and division today stems from a secondhand faith - believers who simply receive human interpretations without searching the Word for themselves. This creates doctrinal dependency: the theological equivalent of eating food you've never seen prepared.
Like the Bereans, we must develop a culture of personal study, guided by the Holy Spirit. As individuals seek the Scriptures with an open, humble heart, the Spirit of Truth aligns our understanding. This personal devotion strips away man-made traditions and aligns us with the true mind of Christ, allowing us to see our brothers and sisters through the lens of God's Word rather than human bias.
Jesus said, *"You will know the truth, and the truth will set you free."* (John 8:32). The freedom He speaks of is not only freedom from sin — it is freedom from the tyranny of religious systems that substitute human authority for the authority of Scripture.
A crucial balance must be maintained here: personal scripture study is not the same as private interpretation unaccountable to the community of faith. The Reformers insisted on *sola scriptura* (Scripture alone as the supreme authority) — but not on *solo scriptura* (only me and my Bible, ignoring two thousand years of Spirit-led interpretation by the church). Good personal Bible study is informed by church history, submitted to accountability, and shaped by the Holy Spirit who has been illuminating the same Word for the same community across the centuries.
**Practical step:** Start a 30-day personal Bible reading discipline. Not a devotional written by someone else — the text itself. Come to it with a notebook, a question, and a prayer: *"Holy Spirit, show me what this means, and show me what it means for how I relate to the rest of Your body."*
Bridge 4: The Rule of Love
**Key Scripture:** *"By this everyone will know that you are my disciples, if you love one another."* — John 13:35 (NIV)
*"And over all these virtues put on love, which binds them all together in perfect unity."* — Colossians 3:14 (NIV)
Love is more than a mere emotion in the Kingdom of Christ. It is the supreme law that governs the body.
Paul's great unity passage in Ephesians 4 does not begin with doctrine. It begins with disposition: “Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace.” - (Ephesians 4:2–3). Humility, gentleness, patience, forbearance, and love are not the results of unity - they are its prerequisites. Love does not demand absolute uniformity in minor opinions; rather, it demands absolute commitment to one another despite our differences. Where love rules, pride and the need to always "be right" die. Without love, every other thing in the body loses its essence.
But we must be clear about what this love looks like and what it does not. Love is not the suppression of truth for the sake of peacekeeping. Paul in Galatians 2 records publicly rebuking Peter to his face when Peter's behaviour contradicted the truth of the gospel (Galatians 2:11–14). That was a costly yet honest love which was concerned with Peter's integrity before the church and before God. The counterfeit of love is niceness that allows error to fester until it destroys.
True love tells the truth gently, patiently, and always with the other person's ultimate flourishing in view. The rule of love does not mean all theological opinions are equally valid. It means all theological conversations are conducted with a commitment to the other person's dignity and to the body's shared health.
Practical Step: Identify one person with whom you have theological tension. This week, do not argue with them. Instead, pray for them specifically. Ask God to bless their ministry, protect their family, and deepen their walk with Him. Do this before the next conversation, and notice what it does to the conversation.
Bridge 5: Honouring the Diversity of Graces and Ministries
**Key Scripture:** *"There are different kinds of gifts, but the same Spirit distributes them. There are different kinds of service, but the same Lord. There are different kinds of working, but in all of them and in everyone it is the same God at work."* — 1 Corinthians 12:4–6 (NIV)
We must recognise that diversity is not the same as division. God never intended for every part of the body to look or function the same way. The hand cannot do the work of the eye, yet both are vital. *"If they were all one part, where would the body be? As it is, there are many parts, but one body."* (1 Corinthians 12:19–20)
We must move from a posture of criticising differences in ministry styles, worship expressions, and spiritual gifts to a posture of honouring them. When we celebrate the unique graces God has deposited in various parts of His body, we move from competition to collaboration — realising we need each other to display the full stature of Christ.
This has direct implications for how we view ministries that operate differently from ours. The contemplative Anglican congregation and the exuberant Pentecostal fellowship, the teaching-focused Reformed church and the prophetically-oriented charismatic community — each is emphasising an aspect of the whole counsel of God that the others need. None is the whole picture by itself.
This does not mean that anything done in Jesus' name is equally valid. Paul himself distinguishes between ministries in 1 Corinthians 12–14 and calls the church to evaluate, weigh, and govern prophetic expression. Discernment is not the enemy of honour - it is the guardian of it. We honour genuine gifts by also protecting the body from counterfeits.
Practical Step: Attend a worship service at a church with a significantly different style or tradition from yours - not to evaluate or critique, but to receive. Ask God to show you what He is expressing through that part of His body that your own tradition tends to underemphasise.
5. What Unity Is NOT: Common Misconceptions
Several things are commonly confused with Christian unity that are not, in fact, unity:
- Unity is not theological indifferentism. The idea that doctrine doesn't matter and all religious paths lead to the same destination is not Christian unity - it is theological relativism, which is specifically condemned in Scripture (Jude 3–4; Galatians 1:6–9). Unity in Christ is built on truth, not on the suspension of all conviction.
- Unity is not conflict avoidance: A church in which no one ever disagrees is not necessarily unified - it may simply be controlled. Biblical unity can absorb and resolve genuine disagreement, as the Jerusalem Council in Acts 15 demonstrates. The apostles faced a significant doctrinal dispute, had a vigorous debate, and arrived at a Spirit-led conclusion that preserved both truth and fellowship.
- Unity is not Organisational merger: The ecumenical movement of the twentieth century attempted to achieve Christian unity primarily through institutional consolidation - creating joint bodies, shared councils, merged denominations. The results were mixed at best. True unity is relational and spiritual before it is organisational.
- *Unity is not the absence of church discipline.** The same Paul who wrote "make every effort to keep the unity of the Spirit" also wrote "expel the wicked person from among you" (1 Corinthians 5:13). Unity does not mean all behaviour and all teaching are equally tolerated. A body that cannot discipline itself is not unified — it is unhealthy.
- *Unity is not the silencing of theological distinctives.** Different theological traditions have developed important emphases that the whole church needs. Reformed theology's careful attention to the sovereignty of God, Wesleyan theology's emphasis on sanctification and human response, Pentecostal theology's recovery of the Spirit's active work in the church — these are not uniformly interchangeable. They are notes in a larger chord. The goal is not to flatten them but to play them together.
6. Practical Steps for Everyday Christians
Unity is not built only by theologians and church councils. It is built (or broken) every day by ordinary believers in ordinary interactions. Here are concrete steps:
- Speak well of other churches and ministers: When you find yourself tempted to criticise another congregation, ministry, or pastor, ask whether your critique is grounded in genuine doctrinal concern or in tribal defensiveness. If the latter, hold your tongue. The rule of Ephesians 4:29 applies: "Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up."
- *Practise the discipline of assumption of good faith.** Before concluding that a believer who worships differently holds wrong motives, assume they are following Christ as best they understand how. This is not naïve — but it is Christian. *"Love... thinks no evil."* (1 Corinthians 13:5 NKJV)
- *Pray specifically for the global body of Christ.** Extend your prayer list beyond your local church to include the persecuted church in nations where faith costs everything, the church in spiritual drought, the church in revival, the church in theological confusion. A broad prayer life produces a broad heart.
- *Learn from traditions other than your own.** Read a book by a serious theologian from a different tradition. Attend a conference hosted by a ministry with a different emphasis. You do not need to adopt everything you encounter, but exposure prevents the insularity that breeds division.
- Refuse to participate in denominational gossip: Every church community has its favourite stories of what other churches are doing wrong. Do not amplify them. Do not repeat them. Do not use them to build your congregation's sense of identity by comparison with what other churches lack. Identity in Christ does not require a competitor.
- Address conflict directly rather than avoiding it or broadcasting it: Matthew 18:15 is the protocol: "If your brother or sister sins against you, go and point out their fault, just between the two of you." Conflict handled publicly before it is handled privately violates both the letter and spirit of Christ's instruction.
7. Frequently Asked Questions (FAQs) About Unity in the Church
Here are some frequently asked
**What does the Bible say about unity in the body of Christ?
The Bible addresses unity extensively. Key passages include: John 17:20–21 (Jesus' prayer for His followers to be one); Ephesians 4:1–6 (the call to preserve the unity of the Spirit with humility and love); 1 Corinthians 12 (the diversity of gifts within the one body); Psalm 133:1 ("How good and pleasant it is when God's people live together in unity!"); and Colossians 3:14 (love as the bond that holds all virtues together in perfect unity).
What is the difference between Christian unity and ecumenism?
Christian unity, as the New Testament describes it, is the spiritual oneness of all genuine believers in Christ — built on the shared foundation of the gospel, expressed through love, and preserved through the Spirit. Ecumenism is a broad movement that sometimes pursues institutional and structural reunion among churches and denominations. Biblical unity does not require organisational merger; it requires shared foundation in Christ, love, and cooperation on the mission of the gospel. Unity that compromises essential doctrine for the sake of visible togetherness is not the unity Jesus prayed for.
Why is the church so divided if Jesus prayed for unity?
The division of the church reflects the ongoing reality of human sin (specifically pride, tribalism, and the desire for preeminence) operating within the community of faith. It also reflects genuine theological disagreements that are not easily resolved. However, the existence of denominations is not itself evidence that Jesus' prayer has failed - the Spirit continues to produce genuine spiritual unity among believers who hold the same foundation, even across structural divides. The task of every generation is to reduce unnecessary division and increase visible, loving cooperation across the body.
How do you promote unity in a divided church?
Practical steps include: returning personally to Christ as the foundation of your identity; distinguishing between essential doctrines (non-negotiable) and secondary matters (where diversity is legitimate); cultivating the dispositions of humility, gentleness, and patience that Paul identifies as prerequisites for unity; refusing to criticise other ministries out of tribal defensiveness; praying specifically for Christians different from yourself; and pursuing shared mission with believers across denominational lines.
Is unity possible without doctrinal agreement?
Unity is possible and required at the level of essential doctrine - the person and work of Christ, the gospel of salvation, the authority of Scripture. At the level of secondary doctrine, unity does not require identical positions but does require mutual love and respect. The standard formula from Reformation theology remains helpful: unity in necessary things, liberty in doubtful things, love in all things.
What breaks unity in the church?
The most common causes of disunity in the church are: pride and the desire for preeminence (3 John 9); the confusion of secondary doctrinal positions with essential ones; competitive rather than collaborative ministry models; secondhand, tradition-dependent faith that produces defensiveness rather than discernment; unresolved personal conflict between members or leaders; and the absence of love as the governing law of community life.
Conclusion: One Fold, One Shepherd
Unity is non-negotiable in Christianity. It is a powerful force the world and all its powers cannot reckon with. It is also the breeding ground of powerful miracles and divine interventions. Unity rooted in love shows our faith in its beauty and divinity.
If we would walk in power, manifestation and fulness of who we are in Christ, unity must be in place — as in the early church. There are different ministers, doctrines, mysteries, and understandings — and that diversity is part of what God designed. But the foundation of all this is undividedly Christ. The unsevered connection must be maintained.
The historic Christian formula stands as our guide: unity in necessary things, liberty in doubtful things, love in all things. Essential doctrine is not the enemy of unity - it is its foundation. Secondary distinctives are not inherently divisive - they are the expressions of a body whose diversity serves a whole too large for any single expression to contain.
The watching world is waiting. It is looking at the Church and asking the question the first century asked in wonder: *"See how they love one another."* Or, in our generation, it is asking with confusion: *"Why can't they?"*
The answer must be found in our generation. Not in a council. Not in a merger. Not in the silencing of theological conviction.
In a return to the foundation. In the enforcement of the law of love. In the daily choice — in homes, in congregations, in online comments, in conversations about other ministries — to be one.
*If a kingdom be divided against itself, will it stand?*
No. And the Enemy of our souls knows this better than we do.
One Fold. One Shepherd.
Let us walk like it.
