Unity in Christ: How Ephesians 2 Breaks Down Walls
Short answer: Unity in Christ is not a mood or a marketing slogan; it is a work of God. Ephesians 2:11-22 says Christ himself broke down the dividing wall of hostility between Jew and Gentile and created one new humanity in himself. The passage begins with a command to remember what believers once were apart from Christ, then traces how his death ended the enmity, how his Spirit gives both groups access to the Father, and how together they are being built into a dwelling place for God. Unity is therefore something Christ accomplished and the Spirit applies, not something we manufacture. Our part is to live out what God has already made true, with humility and patience.
What Ephesians 2:11-22 actually says
The passage opens with a command that is easy to skip: Ephesians 2:11 says, "Therefore remember that once you, the Gentiles in the flesh, who are called “uncircumcision” by that which is called “circumcision” (in the flesh, made by hands)". The verb remember matters. Paul is not asking Gentile believers to dwell on past shame for its own sake, but to recall the distance that grace crossed. They were labeled by a physical marker they did not carry, and the label carried social and religious weight. Remembering that distance produces humility, not pride, in anyone who now belongs to Christ.
The next verses press the point hard. Paul lists what the Gentiles were apart from Christ: separated from Israel, alienated from the covenants, without hope and without God in the world. This is not flattery; it is diagnosis. The problem was not merely bad manners between two groups but a real separation from God and from his people. Any discussion of unity that skips this diagnosis will produce a shallow togetherness. The gospel begins by telling the truth about our condition, and only then announces what God has done about it.
Then comes the turn: but now in Christ Jesus you who once were far off are made near by the blood of Christ. Notice the agent and the means. Christ is the one who acts, and his blood is the means. Unity is not the result of a negotiated settlement between parties who decided to get along. It is the result of a sacrifice. That is why Christian unity has a different character from mere tolerance. It is purchased, not produced, and therefore it is owed, not optional.
The passage goes on to say that he is our peace, who made both one and broke down the middle wall of partition. He abolished the enmity, the law of commandments contained in ordinances, so that he might create in himself one new man from the two, making peace, and might reconcile them both in one body to God through the cross. The language is deliberate and physical: a wall, a body, a cross. Reconciliation with God and reconciliation with each other are not two separate projects; they are one work with two sides.
The dividing wall and what it stood for
The middle wall Paul mentions had a concrete reference his readers would recognize. In the Jerusalem temple, a barrier separated the court of the Gentiles from the inner courts, and warning notices threatened death to any Gentile who passed beyond it. Paul is not merely using a metaphor; he is pointing to a structure that embodied the division. Christ abolished the enmity that the wall represented. The barrier was not a mistake in the Old Testament; it was a temporary arrangement that taught Israel about holiness and separation while the promises were being carried forward.
What changed is that the purpose of that arrangement reached its goal. The law of commandments in ordinances functioned as a boundary marker for a particular people during a particular period. When the promised offspring came, the boundary did its job and was set aside as a dividing barrier. This is not a rejection of the Old Testament; it is the Old Testament reaching its intended destination. The same God who said to Israel, be holy, is the God who now says in Christ, be one. There is no contradiction, only fulfilment.
It is worth being precise here, because this passage is sometimes misused. Paul does not say that moral commands are abolished, nor that God changed his mind about holiness. He says the enmity, expressed in the law of commandments contained in ordinances, was abolished in Christ's flesh. The ceremonial boundary that kept Gentiles at a distance is gone. The moral will of God, which the law also revealed, is not repealed but is now written on hearts by the Spirit. Confusing these two things produces either lawlessness or a rebuilt wall.
Practically, this means that any wall we build in the church on the basis of ethnicity, culture, class, or religious pedigree is a rebuilding of what Christ tore down. We may build walls out of preference, language, tradition, or suspicion, and we may call them wisdom. But if a wall keeps away those whom Christ has brought near, it stands against his work. The passage does not ask us to pretend differences do not exist; it asks us to stop treating them as grounds for separation among those who are in Christ.
One new man, not two improved ones
Ephesians 2:15 says Christ's purpose was to create in himself one new man from the two, so making peace. The phrase one new man is striking. The goal is not two groups that tolerate each other, nor one group absorbing the other. It is a new identity that neither group possessed before. Jewish believers do not stop being Jewish, and Gentile believers do not stop being Gentile, but neither identity is now the foundation of their standing. Christ himself is the foundation, and the new humanity is defined by union with him.
This is why the language of citizenship matters. Ephesians 2:19 says that believers are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God. Citizenship is a shared status, not a shared personality. Two citizens of the same country may differ in language, food, and habits, and still belong to the same nation. In the church, the shared status is far deeper than any national citizenship, because it was purchased by blood and secured by the Spirit.
The passage then shifts to building imagery. Believers are built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone, and the whole building grows into a holy temple in the Lord. The point is corporate. Salvation is personal, but it is not private. No believer is a standalone stone. Each one is fitted into a structure that only makes sense as a whole, and the structure exists for God's dwelling by the Spirit.
If that is true, then disunity is not merely a relational annoyance; it is a construction problem. A wall that divides the building works against the architect's plan. This does not mean every disagreement is a crisis, or that doctrinal boundaries do not matter. It means that the burden of proof falls on those who would divide, not on those who would unite. When we separate over preferences, we should ask whether we are defending the foundation or merely protecting our own comfort.
How Christ's peace becomes our practice
Ephesians 2 tells us what God did; Romans 15:5-7 tells us how to live in light of it. The passage says, "Now the God of perseverance and of encouragement grant you to be of the same mind with one another according to Christ Jesus". Notice that the same mind is something God grants, not something we generate by sheer willpower. It is according to Christ Jesus, which means it is shaped by his example and his priorities rather than by our preferences. Unity is a gift to be received before it is a duty to be performed.
The same passage goes on to speak of glorifying God with one mouth, and then gives the command to receive one another, just as Christ also received us, to the glory of God. The pattern is downward before it is outward. Christ received us while we were far off, not after we had made ourselves presentable. That is the measure of how we are to receive one another. If we wait for others to become like us before we welcome them, we have not yet understood the gospel we claim to believe.
Colossians 3:10-11 supplies the same logic with different imagery. Believers have put on the new man, who is being renewed in knowledge after the image of his Creator, and in that renewal there is no distinction that counts as grounds for exclusion. The old humanity organized itself around status markers; the new humanity is organized around Christ. This is not a claim that all distinctions vanish in daily life. It is a claim that no distinction gives anyone a superior standing before God.
Christian community is one of the ordinary means by which this renewal happens. We do not learn to love people unlike us by reading about it; we learn by sitting with them, singing with them, praying with them, and bearing with them over time. That is slow work, and it is often unglamorous. But it is the work the Spirit uses to shape mature believers who reflect the character of Christ rather than the reflexes of their own social group.
Unity and truth are not rivals
Some Christians treat unity as though it were in tension with truth, as if pursuing one requires neglecting the other. Ephesians 2 does not support that. The unity Paul describes is built on the foundation of the apostles and prophets, which means it is a unity defined by apostolic teaching, not by whatever lowest common denominator happens to be available. The dividing wall came down, but the foundation stayed. Christ is the cornerstone, and a building without a cornerstone is not a building.
That means unity has content. It is unity in Christ, not unity in general. Two people can agree on many things and still not share this unity, because this unity comes from being joined to the same Lord by the same Spirit through the same faith. Conversely, two believers can disagree about secondary matters and still share it. The New Testament consistently treats some disagreements as serious and others as matters of conscience to be borne with patience, and it never treats the difference as a reason to abandon the foundation.
In practice, this calls for discernment rather than slogans. When a division arises, the question is not simply whether people are upset, but whether the issue touches the gospel itself. Some divisions are necessary because the foundation is being denied. Many more are unnecessary because the foundation is intact and the disagreement is about preference, culture, or method. Wisdom is knowing which is which, and humility is being willing to lose an argument rather than fracture a body unnecessarily.
It also calls for honesty. Unity does not mean pretending that real differences do not exist or that every practice is equally good. It means holding those differences in a way that does not deny the common Lord. Romans 15 addresses exactly this kind of situation, where believers differed about matters that were not the foundation. The command was to receive one another, not to settle every question before sharing a table. That is a harder and more durable unity than uniformity.
Why this unity is worth the cost
The stakes are higher than most of us assume. Ephesians 2 ends by saying that in Christ the whole building is fitted together and grows into a holy temple in the Lord, a dwelling place of God in the Spirit. The unity of the church is not merely for the comfort of its members; it is the setting in which God has chosen to dwell. A fractured church obscures the very thing God is building. When believers live in reconciled relationships across the divisions that once defined them, they display something the world cannot manufacture.
That display is the point. The book of Acts records that the first believers held their possessions and their lives in common, and that the watching world took notice. The unity of the church is meant to be visible, not theoretical. It is a sign that the gospel is true, because the gospel claims to reconcile people who had no natural basis for reconciliation. When that reconciliation is absent, outsiders reasonably ask whether the claim is real.
This does not mean every local church will be perfectly unified. Churches are made of sinners, and sin divides. It does mean that unity is a legitimate goal to pursue, a gift to guard, and a mark of spiritual maturity. It means we should be quicker to listen than to accuse, quicker to forgive than to withdraw, and quicker to remember our own rescue than to rehearse someone else's failure. These are not vague sentiments; they are habits that flow from the cross.
The cost is real. Bearing with people unlike us is inconvenient and sometimes painful. It requires giving up the right to win every argument, the comfort of a group that thinks exactly like us, and the satisfaction of being the one who was right. But the passage does not present unity as a burden to be endured. It presents it as the natural outworking of what Christ has done, and it presents the church as the place where God himself dwells by his Spirit. That is worth far more than the walls we are tempted to rebuild.
Biblical fidelity check
Ephesians 2:11-22 establishes several things plainly. It establishes that Jew and Gentile were genuinely separated, that Christ is himself our peace, that he abolished the enmity through the cross, that he created one new humanity, and that believers are now fellow citizens and a growing temple of God. It establishes that this unity is God's work and that the Spirit is the one through whom both groups have access to the Father. It also establishes that the foundation of this unity is the apostles and prophets, with Christ as the cornerstone, so unity never floats free of apostolic teaching.
The passage does not establish that all distinctions are erased, that doctrinal boundaries are unimportant, or that every group calling itself a church shares this unity. It does not promise that local congregations will be free of conflict, and it does not make reconciliation automatic or effortless. A common misreading treats the passage as a mandate to set aside the truth claims of the gospel in order to get along. That is wrong because the same passage grounds unity in the cross, in the Spirit, and in the apostolic foundation. A unity that denies those foundations is not the unity Paul describes but a different thing wearing its name.
Other passages that speak to Ephesians 2:11-22
Several other passages fill out this theme. John 17:20-23 records Jesus praying that all who believe would be one, tying the unity of his people to the credibility of the gospel before the world. Galatians 3:26-29 declares that those who are in Christ are all children of God through faith, so the distinctions that once defined status no longer define standing. First Corinthians 12:12-13 makes the church a body, where many members form one body and were all made to drink of one Spirit. Colossians 3:10-11 describes the new man, renewed after the image of his Creator, in whom the old dividing markers no longer determine who belongs. Each of these passages adds its own angle on the same work of God.

Frequently asked questions
What is the dividing wall of hostility in Ephesians 2?
It refers to the barrier that separated Gentiles from the inner courts of the Jerusalem temple, and more broadly to the enmity the law of commandments had expressed as a boundary. In Ephesians 2:14, Paul says Christ broke down that middle wall of partition in his flesh. The wall was not evil in itself; it marked a temporary arrangement for a particular period. Christ abolished the enmity it represented, so that Jew and Gentile could be reconciled in one body through the cross. The point is that Christ removed the barrier by removing the hostility, not by ignoring it.
Does unity in Christ mean all churches should merge?
No, and Ephesians 2 does not require it. The passage speaks of one new humanity and one body, which is a spiritual reality rooted in union with Christ. It does not mandate a single institutional structure or the removal of every denominational distinction. Faithful Christians differ on questions of polity, worship, and secondary doctrine, and those differences can be legitimate. What the passage rules out is treating such differences as grounds for hostility or contempt among those who share the true foundation, which is Christ and the apostolic gospel, as Ephesians 2:20 states.
How do I pursue unity without compromising truth?
First, know the foundation. Ephesians 2:20 grounds the church on the apostles and prophets, with Christ as the cornerstone. Commitments that deny that foundation cannot be treated as optional, because unity is unity in Christ. Second, distinguish primary from secondary matters. Some disagreements concern the gospel itself; many concern preference, method, and conscience. Third, practice the posture of Romans 15:7, receiving one another as Christ received us. That means patience where the foundation is intact and clarity where it is not, holding both without using one to excuse neglect of the other.
