Introduction

How you treat brothers and sisters in Christ with whom you disagree tells me all I need to know about your walk with Jesus. Furthermore, this simple yet profound truth has echoed through the corridors of Christian history for over two millennia. Moreover, it continues to challenge believers today as we navigate political divisions, worship preferences, and theological differences within the body of Christ.

Throughout my years in pastoral ministry, I’ve witnessed countless moments where loving believers who disagree either demonstrated Christ’s character or sadly fell short of His call to unity. Additionally, these moments often reveal more about our spiritual maturity than our attendance at Sunday morning worship or midweek Bible studies ever could.

Today, I want to take you on a journey through Christian history, beginning with remarkable testimonies from the early church, then exploring Paul’s practical wisdom for handling disagreement, and finally applying these timeless principles to our modern context.

Witnesses from the Early Church: The Epistle to Diognetus

The anonymous author of the Epistle to Diognetus, writing in the second century, painted a stunning portrait of Christian community life that captured the attention of both believers and skeptics. Consequently, this early Christian apologetic work provides us with invaluable insight into how the first generations of believers handled conflict and disagreement.

The epistle describes Christians as a people radically different in how they lived and loved: “They love all men, and are persecuted by all. They are unknown and condemned; they are put to death, and restored to life… They are reviled, and bless; they are insulted, and repay the insult with honor. They do good, yet are punished as evildoers.”

Think about this remarkable description for a moment. These early Christians faced external persecution, yet they responded with blessing rather than bitterness. However, the epistle doesn’t directly address internal disagreement, but it paints a picture of grace under pressure—a community that responded to hostility with blessing. If that’s how they treated outsiders and enemies, how much more should they have extended grace to fellow believers with whom they disagreed?

The author concludes with this powerful metaphor: “To sum up: what the soul is in the body, that Christians are in the world.” Christians function as the soul of the world, bringing life, purpose, and vitality to human society. Nevertheless, just as the soul must work harmoniously with different organs in the body, Christians must learn to work together despite their differences.

This early witness establishes a crucial foundation: loving believers who disagree isn’t just about maintaining peace—it’s about fulfilling our calling as Christ’s representatives in a watching world.

An Enemy’s Testimony: Emperor Julian’s Reluctant Praise

Perhaps even more striking than Christian self-description is the testimony of Emperor Julian, known to history as “Julian the Apostate.” Writing in 362 AD to Arsacius, the pagan high priest of Galatia, Julian expressed his frustration with Christian effectiveness:

“It is disgraceful that the impious Galileans support not only their own poor but ours as well… It is their benevolence to strangers, their care for the graves of the dead, and the pretended holiness of their lives that have done most to increase atheism [by which he meant Christianity].”

Julian’s begrudging admiration reveals something profound about early Christian community life. Even from an opponent’s perspective, the unity and sacrificial care among Christians was undeniable. Moreover, Julian observed that their love wasn’t limited to those with whom they agreed—it extended to strangers and even enemies.

This external testimony carries particular weight because Julian had every reason to criticize Christians harshly. Instead, he found himself compelled to acknowledge their remarkable unity and love, even when it frustrated his own religious and political goals.

Together, these historical witnesses suggest that Christian credibility was built not on uniformity of opinion but on radical love and unity in the face of difference. Furthermore, this legacy challenges us to examine our own witness in an age of increasing polarization.

Paul’s Practical Wisdom: Romans 14 and the Weak and Strong

The apostle Paul faced the challenge of loving believers who disagree head-on in his letter to the Romans. Specifically, Romans 14 addresses disagreements between Jewish and Gentile Christians over dietary laws and sacred days—issues that created significant tension in the early church.

Paul begins with a fundamental principle: “Accept the one whose faith is weak, without quarreling over disputable matters” (Romans 14:1, NIV). The Greek word for “accept” here is proslambano, which means to receive warmly, to welcome into one’s circle. Consequently, Paul isn’t suggesting mere tolerance but active, warm acceptance of those with different convictions.

Paul then presents two groups: the “weak” who feel obligated to observe dietary restrictions and special days, and the “strong” who feel free from such obligations. However, notice that Paul doesn’t dismiss either group as wrong—instead, he calls both to love and mutual respect.

“The one who eats everything must not treat with contempt the one who does not, and the one who does not eat everything must not judge the one who does. For God has accepted them” (Romans 14:3). The word “contempt” (exoutheneo) means to treat as nothing, to despise completely. Meanwhile, the word “judge” (krino) refers to harsh condemnation rather than discernment.

This passage directly addresses how loving believers who disagree should interact. Paul prohibits both contempt from the “strong” and condemnation from the “weak.” Instead, he calls for recognition that God has accepted both groups.

Furthermore, Paul provides a crucial test: “Each of them should be fully convinced in their own mind” (Romans 14:5). This doesn’t mean that all opinions are equally valid, but rather that believers should hold their convictions with integrity before God, not merely to please others or avoid conflict.

First Corinthians 8: Love Over Knowledge

Paul’s handling of the meat-sacrificed-to-idols controversy in 1 Corinthians 8 provides another lens through which to understand loving believers who disagree. Here, Paul addresses Christians who had different levels of knowledge about idol worship and its implications for eating meat.

“We know that ‘We all possess knowledge.’ But knowledge puffs up while love builds up” (1 Corinthians 8:1). The Greek word for “puffs up” (phusioo) suggests arrogant inflation, while “builds up” (oikodomeo) refers to constructive edification—literally building a house.

Paul acknowledges that some believers have greater theological knowledge about the reality that idols have no real existence. However, he warns that knowledge without love becomes destructive rather than constructive. Moreover, he introduces a principle that revolutionizes how we handle disagreement: the stronger believer bears responsibility for the weaker.

“Be careful, however, that the exercise of your rights does not become a stumbling block to the weak” (1 Corinthians 8:9). The word “stumbling block” (proskomma) refers to something that causes another to fall or be injured. Therefore, Paul teaches that loving believers who disagree means the “stronger” party actively seeks to protect and serve the “weaker” rather than simply asserting their rights.

This principle challenges our natural tendency to demand our rights or prove our point. Instead, Paul calls us to consider how our actions might affect our brothers and sisters in Christ, even when we believe we’re theologically correct.

Additional Biblical Foundation: Matthew 18, Ephesians 4, and Galatians 6:1

Jesus Himself provides the framework for handling disagreement in Matthew 18:15-17. When conflicts arise, Jesus prescribes a process that prioritizes relationship restoration over winning arguments. “If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over.”

The goal isn’t victory in debate but restoration of relationship. Furthermore, the process protects both parties’ dignity by starting privately rather than exposing the disagreement publicly.

Ephesians 4:2-3 adds another dimension: “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.” The phrase “bearing with one another” (anecho) suggests enduring or putting up with differences rather than demanding uniformity.

Paul uses military language when he says “make every effort” (spoudazo)—the same urgency a soldier shows in battle should characterize our pursuit of unity. Additionally, notice that Paul doesn’t say “create unity” but “keep the unity of the Spirit”—unity already exists through Christ, and our job is to maintain it.

Galatians 6:1 provides guidance for more serious disagreements: “Brothers and sisters, if someone is caught in a sin, you who live by the Spirit should restore that person gently. But watch yourselves, or you also may be tempted.” The word “restore” (katartizo) means to mend or repair, like fixing a broken net.

This restoration must happen “gently” (pneuma prautetos)—literally “in a spirit of gentleness.” Moreover, Paul warns those doing the restoring to examine themselves, recognizing their own vulnerability to failure.

Modern Applications: Political Differences

In our current cultural climate, political differences often create the most heated disagreements among believers. I’ve watched loving believers who disagree about candidates, policies, and political philosophies sometimes treat each other with less grace than they would show complete strangers.

Whether you lean Democrat or Republican, conservative or progressive, the principles we’ve explored apply directly to political disagreements within the church. Furthermore, Scripture doesn’t endorse any particular political party—it calls us to pursue justice, mercy, and humility regardless of our political affiliations.

Consider how the early church navigated political diversity. Jewish Christians had to worship alongside Gentile Christians who came from the Roman system that oppressed them. Tax collectors (who collaborated with Rome) sat next to zealots (who wanted to overthrow Rome) in the same congregations. Yet Paul never suggests they needed to agree politically to fellowship together.

When political discussions arise in our churches, we can apply Paul’s principle from Romans 14: “Each of them should be fully convinced in their own mind” while refusing to show contempt for those who reach different conclusions. Moreover, we can remember Julian’s observation about early Christians—their care for others, including political opponents, drew people to Christ.

Instead of allowing political differences to divide us, we can demonstrate to a polarized world what loving believers who disagree actually looks like. This doesn’t mean avoiding all political discussion, but rather engaging with the humility and gentleness that marks mature Christian character.

Worship Style Preferences: Hymns vs. Praise Songs

Few things create more passionate disagreement in churches than worship style preferences. I’ve witnessed congregations split over whether to sing “How Great Thou Art” or “How Great Is Our God,” whether to use an organ or a guitar, whether to stand or sit during worship.

These preferences often reflect deeper generational, cultural, and theological differences. However, the principles from our biblical foundation apply directly to these situations. When we examine the heart behind worship style preferences, we often discover that both “sides” genuinely desire to honor God—they simply express that desire differently.

The “hymn people” often value theological depth, historical connection, and reverent tradition. Meanwhile, the “praise song people” often value contemporary relevance, emotional expression, and accessible participation. Both groups want to worship God authentically, yet they sometimes treat each other with suspicion or contempt.

Paul’s teaching about meat sacrificed to idols provides helpful guidance here. Neither worship style is inherently superior, but both can become stumbling blocks when we insist on our preferences over the spiritual well-being of others. Furthermore, loving believers who disagree means considering how our advocacy for particular worship styles might affect our brothers and sisters.

I’ve found that the most spiritually mature believers often show flexibility in worship style while maintaining firm commitment to worship substance. They recognize that God receives glory both from ancient hymns and contemporary songs when hearts are genuinely engaged in worship.

Theological Secondary Issues: Creation, Communion, Baptism, Spiritual Gifts, and Women in Ministry

Some of the most complex disagreements among loving believers involve theological issues that, while important, don’t constitute essential Christian doctrine. These secondary issues—including creation timelines, communion frequency and method, baptism mode and timing, spiritual gifts operation, and women’s roles in ministry—require particular wisdom and grace.

First, we must distinguish between essential and secondary doctrines. Essential doctrines include the Trinity, the deity of Christ, salvation by grace through faith, and the authority of Scripture. Secondary issues, while significant, allow for legitimate disagreement among faithful Christians who hold equally high views of biblical authority.

Regarding creation, some believers hold young-earth views while others embrace old-earth perspectives or theistic evolution. Both groups typically affirm that God created the universe and humanity, but they interpret the biblical and scientific evidence differently. Moreover, both groups include scholars who love Christ and respect Scripture’s authority.

Communion practices vary widely among denominations and local churches. Some celebrate weekly, others monthly or quarterly. Some use wine, others grape juice. Some restrict participation to church members, others welcome all believers. Furthermore, some emphasize remembrance while others stress real presence. These differences reflect theological convictions, not spiritual maturity levels.

Baptism generates similar diversity. Some practice infant baptism, others believer’s baptism. Some require immersion, others accept sprinkling or pouring. Some see baptism as sacramental, others as symbolic. Yet all these groups typically agree that baptism represents our union with Christ in His death and resurrection.

Spiritual gifts create particularly intense disagreements. Some believers embrace all miraculous gifts as normative for today, while others see certain gifts as limited to the apostolic period. Some practice speaking in tongues, others question its contemporary validity. However, both groups generally affirm that the Holy Spirit distributes gifts for the church’s edification.

The role of women in ministry generates passionate discussion among equally committed believers. Some interpret Scripture as limiting women’s pastoral roles, while others see no such restriction. Some emphasize biblical passages about submission, others focus on passages about equality and giftedness. Nevertheless, both perspectives include godly men and women who seek to honor Scripture’s teaching.

In all these areas, loving believers who disagree means approaching these discussions with humility, recognizing that faithful Christians can examine the same biblical texts and reach different conclusions. Furthermore, it means refusing to question others’ commitment to Christ or Scripture simply because they hold different secondary positions.

Social Media Behavior: Digital Discipleship

Perhaps nowhere do we see more failures in loving believers who disagree than on social media platforms. The anonymity and distance of digital communication seem to bring out the worst in Christian discourse, with believers regularly engaging in behavior online that they would never exhibit in face-to-face conversation.

I’ve watched Christians share political memes that mock brothers and sisters with different views, engage in theological arguments that generate more heat than light, and participate in pile-on attacks against fellow believers who express unpopular opinions. Moreover, the speed and public nature of social media amplifies these failures, creating lasting damage to relationships and Christian witness.

The principles we’ve explored apply directly to digital interactions. Paul’s prohibition against contempt and harsh judgment doesn’t include a social media exception. Furthermore, Jesus’ call to private correction before public confrontation suggests that most theological disagreements shouldn’t be aired in public forums where they can become spectacles for non-believers.

Before posting or commenting on controversial topics, we can ask ourselves: “Does this demonstrate the character of Christ? Will this build up my brother or sister in faith? Does this reflect the kind of love that drew Emperor Julian’s reluctant praise?”

Social media also provides unique opportunities to demonstrate loving believers who disagree. We can model gracious disagreement, share content that builds rather than tears down, and use these platforms to encourage rather than attack. Additionally, we can remember that our online behavior contributes to the watching world’s perception of Christianity.

Practical Steps for Loving Believers Who Disagree

Based on our journey through Christian history and biblical wisdom, here are concrete steps for implementing these principles in daily life:

Listen First, Speak Second: Before responding to disagreement, truly listen to understand the other person’s perspective. Often, what appears to be theological disagreement actually reflects different life experiences or cultural backgrounds. Furthermore, listening demonstrates respect and creates space for genuine dialogue.

Assume Good Intentions: Unless clearly proven otherwise, assume that your Christian brothers and sisters hold their positions because they genuinely want to follow Christ, not because they want to be difficult or divisive. This assumption creates a foundation for respectful conversation rather than defensive argument.

Focus on Relationship Over Being Right: While truth matters enormously, relationships also matter to God. Sometimes the most Christ-like response involves setting aside our need to win an argument in favor of preserving a relationship that allows for ongoing influence and mutual growth.

Practice Private Confrontation: When disagreement involves behavior that seems clearly wrong, follow Jesus’ pattern in Matthew 18 by addressing it privately first. Public correction should be reserved for public sin or false teaching that threatens the broader community.

Ask Questions Instead of Making Statements: Questions invite dialogue while statements often end it. Instead of saying “You’re wrong about baptism,” try asking “Help me understand how you interpret the passages about baptism.” This approach demonstrates humility and creates learning opportunities for both parties.

Acknowledge Areas of Agreement: Before diving into disagreements, identify and celebrate areas where you agree. This establishes common ground and reminds both parties that you’re on the same team in the most important matters.

Pray Together: When possible, pray with those with whom you disagree. Prayer reminds us that we both serve the same Lord and need the same grace. Moreover, it’s difficult to maintain hostility toward someone with whom you regularly pray.

The Watching World

Throughout this sermonette, I’ve emphasized that our treatment of believing brothers and sisters with whom we disagree serves as a powerful witness to the watching world. This theme connects directly to Jesus’ prayer in John 17:21: “that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me.”

Christian unity—not uniformity, but unity—serves as evidence of the gospel’s truth. Conversely, Christian division and hostility provide ammunition for those who want to dismiss Christianity as just another human institution marked by the same petty conflicts that plague secular organizations.

The early church’s reputation for love and unity, documented by both the Epistle to Diognetus and Emperor Julian, contributed significantly to Christianity’s growth and influence. People were drawn to a community where love transcended natural barriers of race, class, and nationality. Similarly, our ability to disagree gracefully while maintaining love and respect can serve as a powerful apologetic in our fractured world.

However, this doesn’t mean we should avoid all disagreement or compromise essential truths for the sake of harmony. Rather, it means we should handle disagreement in ways that reflect Christ’s character and demonstrate the transforming power of the gospel.

Living as Soul in the World

The Epistle to Diognetus described Christians as the soul of the world—bringing life, purpose, and vitality to human society. This metaphor provides a beautiful framework for understanding our role in a world marked by division and hostility.

Just as the soul animates and coordinates the body’s various organs, Christians should animate and coordinate society’s various groups and perspectives. We don’t do this by eliminating differences or forcing uniformity, but by demonstrating how people with different viewpoints can work together in love and mutual respect.

When the world sees Democrats and Republicans worshiping together, traditionalists and progressives serving together, and people from different cultures and backgrounds loving each other despite their differences, they see something supernatural. Furthermore, they see evidence that the gospel really does transform human nature and create new communities based on grace rather than similarity.

This witness becomes particularly powerful when we extend this same grace to fellow believers with whom we disagree. If we can’t love Christian brothers and sisters who hold different secondary positions, how can we claim to love a lost world that holds completely different primary positions?

---

The Character Test

Returning to our opening statement: how you treat brothers and sisters in Christ with whom you disagree tells me all I need to know about your walk with Jesus. This isn’t an arbitrary standard—it reflects the deep connection between our horizontal relationships and our vertical relationship with God.

First John 4:20 makes this connection explicit: “Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen.” While disagreement doesn’t equal hatred, our response to disagreement reveals the depth of our love.

Moreover, our treatment of disagreeing believers reflects our understanding of grace. If we believe we’re saved by grace rather than perfect theology, we should extend that same grace to others whose theology differs from ours on secondary matters. Furthermore, if we believe God uses sanctification as a lifelong process rather than instant perfection, we should show patience with those who are at different stages of that process.

The character test also reveals our trust in God’s sovereignty. If we believe God is big enough to save us despite our theological blind spots, we should trust Him to work in the lives of other believers despite their blind spots. Additionally, suppose we believe the Holy Spirit guides believers into truth. In that case, we should allow room for Him to work in others’ lives rather than assuming we must correct every error we perceive.

Hope for Unity

Despite the challenges we face in our current cultural moment, I remain hopeful about the possibility of Christians demonstrating loving believers who disagree. This hope rests not on human ability to overcome natural tendencies toward tribalism and pride, but on the power of the gospel to transform hearts and communities.

The same Spirit who enabled first-century Jews and Gentiles to worship together despite centuries of hostility can enable twenty-first-century believers to find unity across political, cultural, and theological differences. Furthermore, the same Christ who prayed for unity among His followers continues to intercede for us today.

I’ve witnessed remarkable examples of this unity throughout my ministry. I’ve seen conservatives and progressives work together on community service projects, traditionalists and contemporaries collaborate on worship planning, and believers with different theological convictions support each other through personal crises. These glimpses of unity remind me that the gospel truly creates new communities marked by supernatural love.

However, this unity requires intentional effort and spiritual maturity. It demands that we examine our own hearts for pride, prejudice, and selfishness. It requires that we choose love over being right, relationship over reputation, and Christ’s glory over our own preferences.

---

Conclusion: The Legacy We Leave

As I conclude this sermonette, I want to challenge you to consider the legacy you’re creating through your treatment of brothers and sisters with whom you disagree. Future generations will judge our faithfulness not primarily by our theological precision or cultural relevance, but by our love for one another.

The early Christians left a legacy of love that impressed even their enemies and drew thousands to faith in Christ. Moreover, their example continues to inspire and challenge believers today. What kind of legacy are we leaving for future generations?

Will they remember us as the generation that chose political affiliation over Christian unity? Will they see us as the believers who split churches over worship styles and theological secondary issues? Or will they remember us as the generation that learned to disagree gracefully while maintaining deep love and respect for one another?

The choice remains before us every day, in every interaction with fellow believers. Each conversation about politics, each discussion about worship, each theological debate provides an opportunity to demonstrate that loving believers who disagree isn’t just a nice ideal—it’s a practical reality empowered by the gospel of Jesus Christ.

How you treat brothers and sisters in Christ with whom you disagree tells me all I need to know about your walk with Jesus. Furthermore, it tells the watching world everything they need to know about the transforming power of the gospel. May we choose to walk worthy of this high calling, following in the footsteps of those who have gone before us and leaving a legacy of love for those who will come after.
