Gaining Your Brother

September 1, 2026

Six weeks ago I walked slowly through what Scripture does when a believer sins and someone loves him enough to go. I stopped short on purpose. I quoted a single verse out of Matthew 18, and then I wrote this:

“There is more in Matthew 18 for the brother who will not listen, and that deserves a careful reading of its own another week . . .”

This is that week.

I stopped there because Matthew 18 has a particular problem, and the problem is not that churches ignore it. Churches quote it constantly. They quote it the way you quote a policy number. Three steps, in order, and did you follow them. In more rooms than I can count I have heard the chapter referred to entirely in the shorthand of its procedure, by people who could not tell you what else is in it.

Because Jesus did not hand us a paragraph. He set that paragraph inside a chapter, and the chapter is the instruction manual for the paragraph.

What the Chapter Was Answering

Matthew 18 does not begin with conflict. It begins with ambition.

“At that time the disciples came to Jesus, saying, ‘Who is the greatest in the kingdom of heaven?’” (Matthew 18:1 ESV). His answer was not a sentence. It was a child, set down in the middle of the room. “Whoever humbles himself like this child is the greatest in the kingdom of heaven” (Matthew 18:4 ESV).

Everything that follows in the chapter is still answering that question. The warnings about causing a little one to stumble. The parable of the sheep. The process. The seventy-seven times. The servant who would not forgive. All of it is one long answer to men who wanted to know who ranked highest, delivered by the One who had just put a child where the rank was supposed to go.

That matters enormously for what comes later, because a process for handling another believer’s sin is one of the most rank-conscious things a church ever does. Somebody speaks; somebody is spoken about. Somebody is heard; somebody has to listen. Jesus set that machinery down in a room He had already emptied of greatness.

The Sheep, and Where He Put It

Then, just before the process, He tells a parable about a lost sheep.

We sat with this parable two weeks ago, in Luke’s telling, and I want to be honest that we are back at it. But we are not back at the same place, because the setting is different, and in this chapter the setting is the whole argument. In Luke, Jesus tells it to critics who are scandalized that He eats with sinners, and it defends His welcome of them. In Matthew, He tells it to disciples arguing about rank, He tells it about the little ones, and He tells it immediately before He explains what to do when a brother sins.

“So it is not the will of my Father who is in heaven that one of these little ones should perish” (Matthew 18:14 ESV).

That is the sentence the process is standing on. Read the next verse without it and you get a compliance sequence. Read it with the previous sentence still in the air and you get something else entirely: instructions for going after somebody.

The Process, Read in That Light

“If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother” (Matthew 18:15 ESV).

“But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses” (Matthew 18:16 ESV). “If he refuses to listen to them, tell it to the church” (Matthew 18:17 ESV).

Notice the shape of that. One person. Then two or three. Then the church. It is usually described as escalation, and it is, but look at what it is escalating toward. Not severity. Not exposure. Each step opens the room by the smallest amount that might still work, and not one inch more. If the smallest room does the job, nobody else ever learns it happened. Escalation in Matthew 18 exists to shrink a conflict, not to build a case.

And here is the thing I most want you to see about the goal. The aim is stated once, in the first verse, and never stated again. Every step after it inherits the goal. Jesus does not repeat “that you may gain your brother” at the second step or the third, because He does not have to. There is only one purpose in the paragraph, declared at the front, and it is still running when the church is finally told. A step that has stopped aiming at gaining the brother has stopped being this process, whatever else it may be following correctly.

I have been on both ends of one of these conversations, and I can tell you where I have failed. The failure I know best is not skipping a step. It is finishing them. Doing it right, in order, on the record, with a heart that had already quietly settled the question of what I wanted the outcome to be. The steps were clean. I was not going after anybody.

Paul gives the tone the whole thing runs in, in four words: a spirit of gentleness (Galatians 6:1 ESV). That is not a mood for step one that expires at step two. It governs the whole sequence, including the part where the church is told.

What “Tell It to the Church” Means, and What It Does Not

This is the step that gets misused most, so let me say plainly what it is not.

It is not a public airing of something that was never privately pursued. The order is not decoration; the widest room comes last precisely because two narrower rooms were tried first and failed. It is not a verdict announcement, where a decision made elsewhere gets read to a congregation that had no part in it. And it is not a small group of leaders standing in for the church because involving the actual congregation would be awkward. Jesus said the church.

What it is, is the last appeal. The congregation is brought in because a brother’s relationship to the whole body is now genuinely at stake, and because the appeal of a whole church is the most weight the New Testament knows how to bring to bear on a man who will not listen. It is still an appeal. It is not a sentence.

And then the last clause, which sounds harsh until you notice who wrote it down. “Let him be to you as a Gentile and a tax collector” (Matthew 18:17 ESV). This is Matthew’s Gospel. The man whose name is on it was a tax collector when Jesus walked up to his booth and called him. Matthew wrote down a sentence about how a hardened man should be treated, and he was describing the category he himself had been in when Christ came for him.

So what does it mean to treat someone as a Gentile and a tax collector? It means the relationship has changed and the pretending is over; you can no longer relate to him as a brother in good standing, because he is not walking as one. It does not mean he is now beneath your concern. Ask how the One saying this treated Gentiles and tax collectors. He went to their houses. He ate at their tables. He called them by name.

The verses right after it are usually lifted out of this paragraph and used elsewhere. “Whatever you bind on earth shall be bound in heaven” (Matthew 18:18 ESV). “For where two or three are gathered in my name, there am I among them” (Matthew 18:20 ESV). That last one is a favorite for small gatherings and thin attendance, and there is nothing wrong with the comfort people take from it. But its home is here, in this paragraph, and here it says something heavier. When a church does this work the way Christ described it, He is in the room. Which ought to make everyone in that room careful, and ought to make the brother being pursued know exactly who has come after him.

Nobody Gets to Wait

There is a companion passage that quietly removes the most common excuse in church conflict, and almost nobody puts the two together.

“So if you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there before the altar and go. First be reconciled to your brother” (Matthew 5:23–24 ESV).

Put them side by side. If your brother sins against you, you go. If you remember your brother has something against you, you go. Between the two, initiative falls on both parties, which means there is no position in a Christian conflict from which the right move is waiting for the other person.

Most stalled conflicts in a church are two people each waiting for the other to start. Scripture has cut off both retreats. It even interrupts worship to say so.

When Love Simply Covers It

But not every offense is a case, and a church that has forgotten this will process things it should have absorbed.

“Above all, keep loving one another earnestly, since love covers a multitude of sins” (1 Peter 4:8 ESV).

Covering is not denial and it is not conflict avoidance dressed up in a verse. It is a real and frequent Christian act: the decision, made freely by the person who was wounded, that this will not be carried forward. The sharp word in a hard week. The slight that was probably not even aimed at you. Much of what holds a congregation together over decades is people quietly deciding not to make something into a matter.

Two guardrails on it, though. Covering belongs to the one who was wounded. It is never something a third party gets to assign to her because he would prefer the quiet. And love covering a multitude of sins is not a policy for serious, ongoing, unrepented sin that is harming people, which is exactly the situation Matthew 18 was given for. Knowing which is which is the discernment this takes. That discernment is easier in a church where going to a brother is ordinary and small rather than rare and enormous.

Where the Chapter Ends

Then Peter asks the question everyone in the room was already doing arithmetic on. How many times? As many as seven? “Jesus said to him, ‘I do not say to you seven times, but seventy-seven times’” (Matthew 18:22 ESV).

And immediately He tells the story of a servant who was forgiven a debt he could never in ten lifetimes have repaid, walked out of the room, and seized a man who owed him pocket change. The master’s question at the end is the question the whole chapter has been walking toward: “And should not you have had mercy on your fellow servant, as I had mercy on you?” (Matthew 18:33 ESV).

Now stand back and look at what surrounds the process. A shepherd going after one wandering sheep on one side. A forgiven servant who would not forgive on the other. Jesus set the process between a lost sheep and an unforgiving servant. Whatever runs between them was never meant to be cold.

The man being handed these instructions is himself a debtor who was forgiven everything. That is not a sentimental frame around a legal procedure. It is the condition of the person carrying it out, and it decides how the whole thing goes.

If You Sit at a Table

If you serve on an elder board, here are two questions worth carrying into your next meeting.

First: when this process runs in our church, can anyone in the room say out loud what we are aiming at? Not what step we are on. What we want to happen to the man. If the answer takes a while, that is worth knowing early.

Second, and harder: has anyone here ever used the order of these steps to slow something down rather than to protect someone? “You didn’t follow Matthew 18” can be a genuine correction. It can also be a way of not hearing something. You will know which by whether the person saying it is more interested in the process or in the problem.

I will say one thing and leave it, because it belongs to a different article. Scripture does not run every conflict through this chapter. When the person accused holds the office, Paul gives Timothy a different procedure, on purpose, and the separateness of it is the whole point. That is where we go next week.

If You Have Been on the Receiving End

And if you are reading this from the other side of it, I have not forgotten you.

Some of you have had this chapter quoted at you. Not to restore anything, but to stop you talking. You raised something real and were told you had gone about it wrong, and the conversation became about your procedure instead of about what you saw. If that happened to you, you should know that it is a known pattern with a name, and I am going to give it a whole article in two weeks rather than a paragraph here, because it deserves better than a paragraph.

For today, take only this. The chapter that was used against you does not read the way it was quoted to you. It opens with a child put down in the middle of an argument about greatness. It sets a shepherd going out after one sheep. It ends with a warning to a forgiven man who would not extend what he had received. There is not one line in it about protecting an institution, and not one line about managing an inconvenient person out of a room.

You were not wrong to expect better from it. You were reading it right.

Not the Will of Your Father

The whole chapter rests on one sentence, and it is worth carrying out of here on its own.

“So it is not the will of my Father who is in heaven that one of these little ones should perish” (Matthew 18:14 ESV).

That is what all of this is for. Not order for its own sake. Not the church’s comfort, and not its reputation. The Father does not want one of them lost, and a church doing this the way Christ described it is simply a church that has decided to want the same thing He wants.

Gaining your brother is the whole point. If the brother comes back, the process worked, whatever step it stopped on. And if you are the one who has been out in the open country a long time now, wandered off or driven off or simply never gone after: He is not the church that failed to come. He is the One who does not consider you acceptable losses, and He never has.
