What doctrines should I be willing to divide over?
Question 0028
This is one of the most important questions any believer can ask, and it requires careful thought. Get this wrong in one direction, and you will divide over things that should not divide. Get it wrong in the other direction, and you will maintain fellowship with those who deny the gospel itself. The stakes are high. Churches have split over carpet colours and musical instruments, while others have embraced outright heresy in the name of keeping peace. We need biblical wisdom to navigate this terrain.
The Principle of Division
Before discussing which doctrines warrant division, we must establish that division is sometimes necessary. This goes against the grain for many modern believers who assume unity must be preserved at all costs. But Scripture itself commands division in certain circumstances.
Paul instructed the Romans: “I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them” (Romans 16:17). Notice who the divisive people are—not those who stand firm on doctrine but those who depart from it. The faithful are commanded to separate from those who have wandered.
To Titus, Paul wrote: “As for a person who stirs up division, after warning him once and then twice, have nothing more to do with him, knowing that such a person is warped and sinful; he is self-condemned” (Titus 3:10-11). The Greek word for “person who stirs up division” is αἱρετικὸν (hairetikon), from which we get our word “heretic.” This is someone who promotes false teaching that tears apart the body.
John goes even further: “If anyone comes to you and does not bring this teaching, do not receive him into your house or give him any greeting, for whoever greets him takes part in his wicked works” (2 John 10-11). This is startling in its severity. Some teachers are so dangerous that basic hospitality should be denied them, lest we become complicit in their destruction.
These passages establish that division is not always wrong. Indeed, there are circumstances where failure to divide is itself the sin.
First-Order Doctrines: The Gospel Itself
The first category of doctrines that demand division are those that constitute the gospel itself. These are the truths that define Christianity and distinguish it from all counterfeits. To deny these is not to hold a different interpretation but to embrace a different religion.
The nature of God is foundational. Scripture reveals God as one Being eternally existing in three Persons—Father, Son, and Holy Spirit. The Shema declares, “Hear, O Israel: The LORD our God, the LORD is one” (Deuteronomy 6:4), while Jesus commands baptism “in the name of the Father and of the Son and of the Holy Spirit” (Matthew 28:19)—one name, three Persons. Any departure from Trinitarian theology is a departure from the God of Scripture. This rules out modalism (the idea that Father, Son, and Spirit are merely different modes of one Person), tritheism (three separate gods), and subordinationism (the Son or Spirit as lesser divine beings).
The full deity and humanity of Christ is non-negotiable. Jesus is the eternal Son who became flesh (John 1:1, 14), truly God and truly man in one Person. The councils of Nicaea and Chalcedon did not invent this doctrine; they defended what Scripture teaches against various distortions. To deny Jesus’ deity is to deny His ability to save. To deny His humanity is to deny that He could represent us. Either error destroys the gospel.
The substitutionary atonement of Christ is central to salvation. Jesus did not merely die as a moral example or as a demonstration of God’s love in the abstract. He died in our place, bearing our sins, satisfying divine justice on our behalf. “He himself bore our sins in his body on the tree” (1 Peter 2:24). “For Christ also suffered once for sins, the righteous for the unrighteous, that he might bring us to God” (1 Peter 3:18). Any theology that denies substitutionary atonement has gutted the gospel.
Salvation by grace alone through faith alone in Christ alone is the heart of the gospel message. Paul could not be clearer: “For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast” (Ephesians 2:8-9). Any system that adds human merit, religious works, or ecclesiastical rituals as contributing factors to salvation has fallen under the anathema of Galatians 1:8-9.
The bodily resurrection of Christ is not merely one doctrine among many; it is the vindication of everything Jesus claimed and accomplished. “And if Christ has not been raised, your faith is futile and you are still in your sins” (1 Corinthians 15:17). Without resurrection, there is no Christianity. Those who spiritualise or deny the physical resurrection are to be opposed without compromise.
The authority and sufficiency of Scripture forms the epistemological foundation for all other doctrines. If Scripture is not God’s inerrant Word, we have no reliable access to any truth about God. “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness” (2 Timothy 3:16). While believers may disagree about the precise nature of biblical inspiration, any position that denies Scripture’s divine origin, authority, or truthfulness undermines the entire structure of Christian faith.
Why These Doctrines Demand Division
Why are these doctrines grounds for division? Because they determine whether someone has the true God and the true gospel. The person who denies the Trinity does not worship the same God we worship. The person who denies substitutionary atonement does not preach the same salvation we preach. These are not merely alternative Christian perspectives; they are different religions wearing Christian vocabulary.
This is why Paul pronounced anathema on those who preached a different gospel (Galatians 1:8-9). This is why John forbade welcoming those who denied the teaching of Christ (2 John 10-11). This is why Jude urged believers to “contend for the faith that was once for all delivered to the saints” (Jude 3). The faith has content, and that content must be defended.
Division over these matters is not optional. Fellowship with those who deny gospel essentials is not love; it is complicity. We are not being harsh when we draw these lines; we are being faithful. The eternal destinies of souls are at stake.
Second-Order Doctrines: Significant but Not Salvific
The second category of doctrines are those that are significant for church life and practice but do not determine salvation. Genuine believers disagree on these matters, and such disagreement does not indicate that one party has apostatised. However, these doctrines are sufficiently important that they may prevent close partnership in certain ministry contexts.
Baptism is a clear example. Some Christians practise infant baptism, understanding it as the New Covenant sign replacing circumcision and appropriate for children of believers. Others, including Baptists, hold that baptism is for believers only, following personal profession of faith. Both positions are held by sincere, Spirit-filled Christians who love Jesus and believe the Bible. But a church cannot practise both simultaneously. A Baptist church cannot have a Presbyterian pastor administering infant baptism, and vice versa. This is a matter where church-level separation exists without personal animosity or denial of one another’s salvation.
Church government fits the same pattern. Some churches are episcopal, with bishops exercising authority over multiple congregations. Some are presbyterian, with elders governing collectively across churches. Some are congregational, with the local body making decisions under Christ’s headship. Each position claims biblical support. Each has produced faithful churches throughout history. But these different polities cannot function together in the same congregation, so churches organise according to their convictions.
The continuation or cessation of certain spiritual gifts is another second-order issue. Cessationists believe that miraculous gifts like tongues, prophecy, and healing ceased with the apostolic age. Continuationists believe these gifts remain available today. This affects worship practice, expectations in ministry, and church culture. Congregations typically align with one position or the other, though both camps include genuine believers.
Views on women in church leadership also fall here. Complementarians hold that Scripture restricts the office of elder/pastor to qualified men, while affirming women’s full spiritual equality and vital ministry roles. Egalitarians believe all leadership positions are open to both men and women. Churches function according to one view or the other, and this conviction legitimately shapes church structure and practice.
How to Handle Second-Order Disagreements
How should we approach second-order disagreements? With conviction and charity in equal measure. We should hold our positions firmly, believing them to be biblical. I am a Baptist who practises believer’s baptism by immersion because I believe that is what Scripture teaches. I am not going to pretend otherwise. But I recognise my Presbyterian brother as a brother, indwelt by the same Spirit, loving the same Lord, proclaiming the same gospel.
At the church level, we organise around shared convictions. A church has to decide how it will baptise, who can serve as elders, and what view of spiritual gifts shapes its practice. These decisions necessarily create distinctions between congregations. But at the level of personal fellowship and broader cooperation in evangelism and ministry, Christians across these divides can and should work together.
The key principle is this: we do not divide personally over second-order issues, but we may organise separately. I can love my Methodist neighbour as a brother while explaining why our church practises differently. I can partner with an Assemblies of God church on community outreach while maintaining my cessationist convictions. Unity and distinctiveness are not opposites.
Third-Order Doctrines: Matters of Conscience
The third category of doctrines are matters where Scripture either does not speak directly or speaks in principles that allow for various applications. These are matters of wisdom and conscience rather than clear biblical mandate.
Eschatological details beyond the core truth of Christ’s return fit here. I hold to a pretribulational rapture and premillennial return of Christ, and I believe this position best accounts for the biblical data. But I have brothers who are posttribulational or amillennial. We can fellowship together without difficulty because these differences do not affect the gospel or church practice in ways that demand separation.
Questions about worship style, Bible translation preferences, the use of alcohol, observance of particular days, and similar matters also fall in this category. Romans 14 addresses precisely these issues, commanding mutual acceptance without requiring agreement. “One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind” (Romans 14:5).
Division over third-order doctrines is almost always sinful. It elevates personal preference to the level of divine mandate. It treats disputable matters as though they were gospel essentials. The person who refuses fellowship over Bible translation or musical instruments has made an idol of their preference and violated the clear command to accept one another.
Practical Wisdom for Division
When facing a potential doctrinal division, several questions can guide discernment. First, is this doctrine clearly taught in Scripture, or am I elevating an inference to the level of explicit biblical teaching? Many divisions occur because one party treats their interpretation as though it were the clear teaching of the text, when in fact godly people have read the same passages differently.
Second, what has the Church historically taught on this matter? The great creeds and confessions of the Church represent centuries of careful reflection on Scripture. When the entire Church has affirmed something—like the Trinity or the deity of Christ—we should be very hesitant to depart from it. When godly Christians throughout history have disagreed—like on baptism or church government—we should be humble about our own position.
Third, what are the spiritual consequences of getting this wrong? Denying the deity of Christ means worshipping a false god and trusting in one who cannot save. Getting the timing of the rapture wrong means… holding an incorrect eschatological position while still trusting in the same Jesus. The stakes are not the same.
Fourth, can I maintain fellowship while disagreeing? If yes, then I probably should. The burden of proof lies on the one seeking division, not the one seeking unity. Division must be justified by clear biblical warrant and genuine spiritual necessity.
Conclusion
We should be willing to divide over first-order doctrines—the truths that constitute the gospel itself. These are the hills worth dying on, the lines that cannot be crossed. To compromise here is to lose everything.
We should maintain church-level distinctions on second-order doctrines while recognising fellow believers who hold different positions. These matters shape our ecclesial practice without determining our eternal destiny.
We should refuse to divide over third-order doctrines, receiving one another in love despite differences in matters of conscience and preference.
The wisdom to know the difference is perhaps the greatest need in the Church today. May God grant us the courage to stand firm where standing is required, and the humility to embrace one another where embrace is appropriate.
