United in Christ, Even When We Disagree
Finding Christian Unity Through Our Common Faith in Jesus Christ
Christians disagree about many things. Theology, politics, biblical interpretation, ethics, and church practices can all become sources of conflict. But when those disagreements threaten to divide a congregation, what does it mean to remain united in Christ?
In 1 Corinthians 1:10–13, the Apostle Paul appeals to believers to agree with one another, avoid divisions, and be united in mind and purpose. It’s a challenging instruction, especially when Christians hold deeply different convictions.
This sermon explores how Christians can disagree without becoming divided, why quarrels and competing loyalties threaten the church, and how a shared commitment to Jesus Christ provides the foundation for Christian unity.
What Does Paul Teach About Christian Unity?
Writing to the church in Corinth, Paul addresses believers who have begun identifying themselves with different leaders. Some claim to follow Paul, others Apollos, others Cephas, and still others Christ.
Paul challenges these divisions by asking whether Christ himself has been divided.
We identify four principles from Paul’s teaching:
- Jesus Christ alone can keep believers united in a common mind and purpose.
- Splits, quarrels, and competing groups will happen, but Christians must recognize and resist these patterns.
- When unity begins to fragment, believers should realign their thinking around Jesus Christ.
- Christians must actively work to preserve unity while allowing freedom to disagree about other matters.
The central distinction is between agreeing about Jesus Christ and requiring agreement about everything else. Christians can share a common faith in Jesus while holding different opinions about theology, ethics, politics, and church practices.
Why Do Disagreements Cause Division in the Church?
Paul’s warning about division addresses several patterns that continue to challenge Christian communities.
Splits tear apart relationships that should remain connected. Quarrels create ongoing contention and struggles over whose opinion will prevail. Factions encourage people to identify with their own groups while distancing themselves from those who think differently.
Yet, underlying these patterns is a recurring human temptation: the desire to control others.
Rather than accepting that another Christian may disagree, we may insist that the other person adopt our position. Differences become struggles for authority, and maintaining our own point of view becomes more important than preserving fellowship.
The preacher also challenges the tendency to embrace only selected aspects of Jesus that support our existing beliefs. Different groups may emphasize different parts of his life and teachings while overlooking the fullness of who he is.
Paul’s response is to bring believers back to their common foundation in Christ.
Coming Alongside One Another Instead of Seeking Control
One of the central ideas comes from Paul’s use of the word appeal.
Pastor Gareth explains this word through the image of coming alongside another person. Rather than standing over someone, standing against them, or attempting to control them, Paul approaches believers as people with whom he seeks agreement. This becomes especially clear in Paul’s letter to Philemon. Although Paul explains that he has the authority to command what is right, he chooses instead to appeal on the basis of love. He wants a good action to be voluntary rather than forced.
He offers us a practical model for handling disagreements within the church.
Christians can debate, reason together, and express strong convictions. But Paul’s approach challenges the assumption that unity can be achieved by forcing others to agree. Instead, Christian unity calls believers to come alongside one another, even when significant disagreements remain.
Maintaining the Unity of the Spirit
In Ephesians 4:1–6, Paul calls Christians to live with humility, gentleness, patience, and love, making every effort to maintain the unity of the Spirit through the bond of peace.
Instead of investing energy in suspicion, distrust, gossip, and division, we are called to strengthen our common trust in Jesus. This does not eliminate differences of opinion. Christians may continue to disagree about significant theological, ethical, and practical questions. But those disagreements need not prevent us from remaining together in faith.
Pastor Gareth compares this commitment to a long-lasting marriage, where people may disagree about many things while maintaining a shared foundation for their relationship.
Having the Mind of Christ
Concluding with Philippians 2:1–8, where Paul urges believers to share the same mind and love, setting aside selfish ambition and considering the interests of others, Paul points to Jesus Christ as the example of humility and self-sacrifice. Although Christ existed in the form of God, he humbled himself and became obedient even to death on a cross.
Likewise, following Jesus may require believers to lay down their own interests, relinquish the desire for control, and demonstrate sacrificial love toward people with whom they disagree.
Having the mind of Christ means allowing his humility, love, and willingness to serve others to shape how Christians relate to one another.
Our Unity Is Found in Jesus Christ
Agreement about Jesus Christ allows Christians to disagree about many other matters without dividing the church. Paul’s call to unity challenges believers to recognize Jesus Christ as their common head and purpose. While Christians may disagree about theology, ethics, politics, and biblical interpretation, those differences need not destroy our fellowship when our shared commitment remains centered on Christ.
Unity requires humility, patience, listening, and a willingness to love people whose convictions differ from our own.
