Everyone in the small congregation knew. The man had left his wife and moved in with a woman from work, and he still came to church most Sundays, sat in the fourth row, and took communion. People talked about it in the parking lot and over the phone that afternoon. What nobody did was talk to him. Months passed. The wife stopped coming because she could not bear the sight of him being greeted warmly at the door. Eventually a few other families drifted away too, not because of what he had done, but because of what the church had not done. The whole thing dissolved into silence and resentment, and nobody could quite say when the damage happened.
That story, with the details rearranged, plays out in congregations constantly. The alternative, the thing Jesus actually prescribed, has fallen out of use in most churches, and where it survives it has often been handled so badly that the phrase "church discipline" makes people flinch. Both the neglect and the abuse come from the same place: a failure to read Matthew 18 carefully and to notice what it is for.
Where the Passage Sits
Matthew 18:15-20 does not arrive out of nowhere. The chapter opens with the disciples arguing about who is greatest, and Jesus putting a child in front of them. He warns, fiercely, against causing "one of these little ones" to stumble. Then He tells the parable of the shepherd who leaves ninety-nine sheep on the hills to go after one that wandered off, and ends with this: "it is not the will of my Father who is in heaven that one of these little ones should perish" (Matthew 18:14).
That is the sentence immediately before the instructions on confronting a sinning brother. The context is not a courtroom. It is a search party. Everything Jesus says about confrontation is framed as the shepherd going out after the one who wandered.
And what comes after? Peter asks how many times he has to forgive, offering seven as a generous estimate, and Jesus says seventy-seven, then tells a story about a servant forgiven a staggering debt who throttles a colleague over pocket change. So the process of correction is bracketed on one side by a shepherd who refuses to write anyone off and on the other by a warning against anyone who receives mercy and then withholds it. Read with those bookends in place, it becomes very hard to use Matthew 18 as a weapon. Read without them, it becomes very easy.
The Steps, Taken Slowly
Start Small and Private
"If your brother sins against you, go and tell him his fault, between you and him alone" (Matthew 18:15). Two words carry most of the weight here: go and alone.
Go means the burden falls on the one who noticed, not on the offender to figure it out, and not on the pastor to handle it for you. Alone means no audience, no text thread, no "I'm just asking for prayer about this." The first move in Jesus' process is a private conversation, which is also the hardest one and the one most often skipped. We would rather tell four people how concerned we are than tell the one person who could actually do something about it.
Notice the goal stated outright: "If he listens to you, you have gained your brother." Not won the argument, not established the facts, not protected the institution. Gained. The language is the language of recovery, of something lost being found again. Paul uses the same instinct in Galatians 6:1, telling those who are spiritual to restore a brother "in a spirit of gentleness," and then adding a line that should hang over every such conversation: "Keep watch on yourself, lest you too be tempted." You go as someone who knows how easily this could be you.
Some manuscripts of Matthew 18:15 read simply "if your brother sins," without "against you," which widens the scope from personal offense to sin generally. Either way, this is not a mandate to audit your neighbor's life. Jesus had already warned about the log in your own eye (Matthew 7:3-5). This is for sin that is real, serious, and clear, not for preferences, personality, or the music in the second service.
Take One or Two Others
If the private conversation fails, Jesus says to bring one or two others along, citing the Old Testament principle that "every charge may be established by the evidence of two or three witnesses." This is a protection, and it cuts in both directions. It protects the accused from one person's misperception, grudge, or faulty memory. It protects the one raising the concern from being dismissed or quietly retaliated against. It slows the whole thing down and introduces sober, outside eyes.
Paul applies the same safeguard to leaders in 1 Timothy 5:19, insisting that no accusation against an elder be received "except on the evidence of two or three witnesses," and then, strikingly, that persistent sin among leaders be rebuked publicly. The safeguard was never meant to make leaders untouchable. It was meant to make the process fair for everyone, including the people with the least power in the room.
Tell It to the Church
Only if that fails does the matter come before the congregation, and even then the aim has not changed. The church speaks with one voice to say: we love you, we see what this is doing to you, please come back. The gravity of the step is the point. It is a last appeal, not a sentence.
Then the line people stumble over: "let him be to you as a Gentile and a tax collector" (Matthew 18:17). It sounds like excommunication, and in a real sense it is. The person is no longer treated as a brother inside the fellowship. But consider who is writing these words. Matthew was a tax collector when Jesus called him (Matthew 9:9). Jesus ate with tax collectors so often it became the standard accusation against Him, and His answer was, "I desire mercy, and not sacrifice" (Matthew 9:13). To treat someone as a Gentile and a tax collector, in Jesus' own practice, is to treat them as an outsider who desperately needs the gospel and who will be pursued with dinner invitations. Paul says it plainly to the Thessalonians: "Do not regard him as an enemy, but warn him as a brother" (2 Thessalonians 3:15).
The two famous verses that follow, about binding and loosing and about two or three gathered in Christ's name, are not general-purpose promises about prayer meetings. In context they are Jesus guaranteeing His presence and authority in exactly this painful work. He is saying that when a church does this carefully and in His name, He is in the room.
The Hard Case in Corinth
Matthew 18 assumes the sin is hidden enough that a private conversation makes sense. First Corinthians 5 handles the other kind. A man in the church was sleeping with his father's wife, the whole city apparently knew, and the Corinthians were proud of themselves for their tolerance. Paul is appalled, not primarily at the man, but at the church: "And you are arrogant! Ought you not rather to mourn?"
His instruction is severe. Remove him from the fellowship, "deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord." Even here, in the harshest sentence Paul passes on anyone, the purpose clause is salvation. The removal is not revenge. It is an attempt to let a man feel the full weight of what he has chosen, outside the warmth of the community that was insulating him from it, in the hope that he comes to his senses.
Paul gives a second reason too: "a little leaven leavens the whole lump." Sin that is publicly known and publicly tolerated does not stay contained. It teaches everyone watching what the church actually believes, regardless of what is preached. And he draws a hard boundary around the whole enterprise: "What have I to do with judging outsiders?" (1 Corinthians 5:12). This is housekeeping, not a campaign against the surrounding culture. The church has no mandate to discipline people who have not placed themselves under its care.
The sequel matters as much as the original command. In 2 Corinthians 2, writing about a disciplined man, Paul says the punishment "is enough," and urges the church to "forgive and comfort him" so he is not "overwhelmed by excessive sorrow," and then to "reaffirm your love for him." Discipline that has no door back in is not biblical discipline. It is exile with a verse attached.
How It Goes Wrong
The abuses are not hypothetical, and pretending otherwise is why so many people distrust the whole subject.
The most common distortion is gossip wearing a halo. A concern gets shared with six people before it reaches the one person it concerns, and by then the process is already poisoned. The second is discipline applied to the wrong things: leaving for another church, questioning a leader's decision, disagreeing on a secondary doctrine, failing to give enough. Scripture reserves formal discipline for serious, unrepentant sin, not for insufficient loyalty.
The third distortion is the one that has done the most harm. Where leaders control the process, the process protects leaders. Accusations get buried, victims get told they are being divisive, and the two or three witnesses rule gets twisted into a reason to ignore a lone voice. A system designed to recover the wandering sheep becomes a tool for managing the shepherd's reputation. Jesus' warning about causing little ones to stumble sits three paragraphs above these verses for a reason.
One thing should be said without qualification. When sin is also a crime, especially abuse of a child or a vulnerable person, Matthew 18 is not the governing text. Romans 13 is. Civil authority "does not bear the sword in vain," and churches are obligated to report such things to the police immediately, not to run an internal process first. A private conversation with an abuser is not a step toward restoration. It is a warning that gives him time.
The Cost of Doing Nothing
Churches avoid all of this for understandable reasons. It is unpleasant. It risks relationships and giving units. It can make a congregation look judgmental. So the common solution is to say nothing and hope the person drifts away or works it out privately.
But the silence has a price, and it is usually paid by the wrong people. The wife in the fourth row pays it. The young believer who concludes that what the church says on Sunday has no connection to how anyone actually lives pays it. The sinning man himself pays it, left alone with a conscience nobody disturbed, which is not kindness. James ends his letter with the opposite vision: "whoever brings back a sinner from his wandering will save his soul from death" (James 5:20). Doing nothing is not neutral.
And membership in a church that never does this means very little. If there is no way to be out, there is nothing meaningful about being in. The word becomes a mailing list rather than a covenant, and the promise congregations make to one another, to watch over each other's souls, quietly expires.
The First Step Is Usually the Last
Here is what most discussions of church discipline miss: the overwhelming majority of it never gets past verse 15. One friend says to another, over coffee, "I need to tell you something I've noticed, and I'd rather say it to your face than think it behind your back." And the other person, after a long and uncomfortable pause, says, "I know. I've been afraid someone would notice." That is church discipline. It is already complete. Nobody files a report. Nobody stands before the congregation. A brother was gained, which was the whole objective from the beginning.
If your church has a formal process, you want it to exist the way you want a fire extinguisher on the wall: available, maintained, rarely used. What you actually need, week to week, is a congregation where people love each other enough to say hard things directly and humbly, and are loved enough to hear them. That culture cannot be installed by policy. It grows slowly, in churches where leaders go first, where confession is normal, and where the people who speak up are not punished for it.
Think of someone you have been talking about rather than talking to. Jesus' instruction is startlingly simple, and it does not require a committee. Go. Alone. Gently, aware of how easily it could be you. The shepherd in the story left ninety-nine sheep for one, and He did not do it to punish the one He found.
