Short answer: In Matthew 18:15–20 Jesus lays out a sequence for a brother who sins: go alone, then take one or two witnesses, then tell the assembly, and only if he refuses to hear the assembly treat him as an outsider. The gathered disciples are authorized to bind and release, and Jesus promises his presence where two or three gather in his name. That authority is real but derivative and remedial: it exists to regain the brother, it works by testimony and agreement rather than private whim, and it is bounded by the command to forgive seventy times seven that follows.
The setting and shape of Matthew 18:15-20
These verses belong to a block of Jesus' teaching to his disciples in Matthew's fourth large discourse, and they begin right after the parable of the lost sheep. That parable ends with the Father's will that not one of these little ones perish, and the note of seeking the stray carries straight into what follows. So the procedure is framed by concern for the one who wanders, not by a desire to be rid of him. The unit also runs directly into Peter's question about how often to forgive, which keeps the whole passage inside a conversation about mercy.
The literary shape is a short sequence: a private conversation, then one or two witnesses, then the assembly, then a pronouncement about binding and releasing, closing with a promise about agreed prayer and Christ's presence. The witness step is not a new invention; it applies the Old Testament rule that a charge stands only on the testimony of two or three. The word assembly places the saying within Matthew's portrait of a gathered people who hear Jesus' teaching and live under his authority. The goal stated in 18:15 is to gain the brother back.
The saying about binding and releasing follows immediately from the assembly's refusal to hear, so it describes the weight of that final step rather than a general power to legislate. Read in isolation, this sequence can be turned into a mechanism for shunning or public humiliation. What guards against that is the setting: the shepherd seeking the stray, the stated aim of gaining the brother, and Peter's question that draws out the answer about forgiving seventy times seven. The passage is case law for a community of disciples, and its purpose is restoration.
The closing promise about two or three gathered in his name is not a technique for getting requests granted. It sits at the end of a procedure concerned with a straying brother, and it assures the gathered community that Jesus is present among them as they act in his name. The agreement in prayer is set within that context of seeking and restoring. Read this way, the passage gives a local church both a serious process and a clear direction: the goal is the brother's recovery, and the surrounding call to limitless forgiveness keeps the process from hardening into expulsion.
The words Jesus gave for a brother who sins
The passage begins with motion, not with a tribunal. If your brother sins against you, Jesus says, go and show him his fault between the two of you alone. The phrase is plain: expose the wrong so it can be dealt with. It is not a word for announcing a scandal or shaming a man in front of others. The setting is private and the goal is stated in the same sentence, that you might gain your brother back. Everything that follows depends on that aim. A process that leaves a brother lost while everyone else feels informed has missed the point Jesus made first.
Only if he will not listen does the circle widen, and it widens to one or two more. Jesus grounds this in the old requirement that a matter be established at the mouth of two or three witnesses. The second step therefore protects the accused as much as it presses him: no one should be condemned on a single person's word. If he still refuses, tell it to the assembly, the ordinary word for the gathered congregation. Treating him as a Gentile or a tax collector describes a changed standing, not a license for contempt. The same Lord ate with tax collectors.
Then Jesus speaks of binding and releasing, picture words for declaring what is forbidden and what is permitted, and of two or three gathered in his name, which means assembled on his authority and for his sake. These promises sit inside a chapter about a shepherd who rejoices over one found sheep, and they are followed at once by Peter's question about forgiveness and the answer, seventy times seven. So the assembly's authority is not a warrant for shunning or public humiliation. The stated goal remains gaining the brother, and the surrounding call is limitless forgiveness.
Pursuing the brother: authority that serves restoration
Matthew 18:15–20 sits inside a parable, and the parable sets the tone. A shepherd leaves ninety-nine sheep to search for one that has wandered, and Jesus says, "Even so it is not the will of your Father who is in heaven that one of these little ones should perish." That sentence governs everything that follows. The procedure Jesus describes is a search, not a purge. A brother who sins is pursued: first privately, then with one or two witnesses, then before the gathered disciples. Each step widens the circle only because the earlier step was refused. The goal is stated plainly in 18:15: the one who listens has been gained back. Read the paragraph with the parable still in view, and the whole process looks like a rescue.
The steps themselves borrow from ordinary legal practice. The rule about two or three witnesses echoes the Old Testament requirement that a charge stand only on tested testimony, so Jesus applies case law to the community of disciples rather than inventing a new tribunal. Notice what that rules out: no accusation rests on one person's private impression. The assembly enters only after repeated refusal to hear. Then comes the saying about binding and releasing in 18:18, and its placement matters. It follows directly on the assembly's verdict, describing the weight of that final step rather than granting a general power to legislate. Authority here is derivative and remedial, exercised by agreement and testimony, never by whim.
The sentence that follows keeps the procedure from hardening into a machine for expulsion. Peter asks how often he must forgive a brother, offering seven times, and Jesus answers with seventy times seven. That number is not a new ceiling; it removes the ceiling. So the step of treating a hardened offender as an outsider in 18:17 must be read beside the command to forgive without limit, and beside the promise of 18:20 that where two or three gather in his name, he is there among them. Leaders should guard the stated aim, gaining the brother, and refuse any use of this passage to justify shunning or public humiliation.
Where readers differ on restoring a brother
Evangelical readers agree the steps of Matthew 18:15–17 are real, but they part ways on the last one. Some hear in "let him be to you as a Gentile or a tax collector" a formal act of exclusion from the fellowship, a deliberate putting outside. Others point out that Jesus ate with tax collectors and welcomed Gentiles, so they read the step as a change in ordinary association rather than a pronouncement of condemnation. A second disagreement runs alongside it: does this passage set up the structures of a local church, or does it describe any two or three disciples handling a private wrong? The text names a personal sin, known and specific, not a general suspicion.
The saying about binding and releasing in 18:18 raises another question. Some readers take it as judicial authority given to a gathered congregation, so that its decisions on earth carry weight in heaven. Others hear it as a restatement of the promise already made to Peter, now widened to the disciples who do the hard work of restoration, and they stress the unusual wording: what is bound will have been bound, suggesting the church declares what God has already decided rather than deciding on its own. The agreed prayer of 18:19 is disputed too, whether it is a general guarantee or a specific assurance for this difficult work.
What limits the text sets are worth naming plainly. The sin is personal and known, the process moves in steps, and the goal is stated: gaining the brother back. Judgment is a last resort, not a first instinct, and it sits beside Peter's question and the answer about seventy times seven, which keeps forgiveness in view. Across these disagreements, what stays central is that the church pursues the straying with truth and patience, and that Christ is present in the gathering that acts in his name. Leaders should guard that goal against any use of this passage to justify shunning or public humiliation.
The shepherd's authority in the gathered church
Jesus gives these instructions immediately after telling the parable of the lost sheep, and he does not change subjects. The shepherd who leaves the ninety-nine to search for the one is the one now saying, "If he finds it, most certainly I tell you, he rejoices over it more than over the ninety-nine which have not gone astray." Matthew 18:13. He adds in 18:14 that the Father does not will that one of these little ones perish. So the steps that follow have a shepherd's goal: to gain back a brother, not to discard him. Discipline that begins anywhere else has already missed the point.
The process itself is restrained. Go alone first and show him his fault privately, and only if he will not listen take one or two others, then tell the assembly. The goal is stated plainly: "If he listens to you, you have gained back your brother." Matthew 18:15. The widening circle exists to win him, not to shame him. When Jesus says to treat the unrepentant man as a Gentile or tax collector, he has just described the shepherd's search for the stray and the Father's unwillingness that any should perish. That comparison should make leaders slow to shun and quick to keep seeking.
The authority here belongs to Christ, not to the group. He promises, "For where two or three are gathered together in my name, there I am in the middle of them." Matthew 18:20. The assembly acts with his authority only because he is present among them, and the binding and loosing of 18:18 is his, not theirs. Peter's very next question about how often to forgive, answered with seventy times seven, guards the whole passage. The mercy we have received in Christ sets both the motive and the limit for every step of correction.
What faithful response looks like when a brother sins against you
Start with yourself. Jesus says that if your brother sins against you, you go to him alone and show him his fault (18:15). Notice the direction: the wronged person moves toward the one who wronged him, before telling anyone else. The aim is stated plainly, that you may gain your brother back. That is a different goal from winning an argument or assembling allies. Private conversation protects the person and keeps the door open. Most offenses could stop here if we obeyed this first step. Speaking to everyone except the person involved is not obedience to this verse; it is avoidance dressed up as concern.
If the private conversation fails, take one or two others who can hear both sides fairly, following the pattern of established testimony (18:16). The witnesses are not there to take your side but to listen and confirm what is true. Only after that does the matter go to the assembly (18:17). This final step should be rare and tearful. Treating someone as an outsider describes a sad relational reality, not permission for contempt or public humiliation. Leaders must guard the stated goal of gaining the brother, and remember that the Lord who commands this process also commands limitless pardon (18:21–22).
Do all of it in his name and in dependence on his presence. Jesus promises that where two or three gather in his name, he is there among them (18:20). That promise steadies a difficult meeting, but it does not guarantee the outcome we want. The brother may refuse to listen. Forgiveness may still be refused by the one who was wronged. We obey, speak honestly, and leave results with the Father, whose will is that none of these little ones perish (18:14). The discipline and the pardon come from the same Lord, so we practice both with humility.
Biblical fidelity check
Matthew 18:15–20 must be read in its setting: Jesus has just told the parable of the lost sheep and then answers Peter's question about repeated forgiveness. The steps are specific. A personal sin is named privately, then confirmed by witnesses, then brought to the gathered congregation, and the goal is gaining the brother. Readers face real interpretive risks here: taking "as a Gentile or a tax collector" as license for contempt, treating the promise of agreed prayer as a blank guarantee, or lifting verses 19–20 out of the restoration process they serve.
Evangelical readers genuinely differ over whether the final step means formal exclusion or a changed relational standing, and over how far the passage governs institutional church structures rather than the informal gathering of disciples. They also differ over whether binding and releasing grants judicial authority to a congregation or restates the promise given to Peter, and whether agreed prayer is a general guarantee or a specific assurance for restoration. What stays central is that the church pursues the straying with truth and patience, that judgment is a last resort, and that Christ is present where two or three gather in his name.

Frequently asked questions
When should a Christian take a sin to the whole church rather than settling it privately?
Jesus moves to the assembly only after private reproof and then one or two witnesses have been refused. The text says to tell it to the assembly if he refuses to listen to them, so the whole-church step is a last resort after earlier attempts to regain the brother have failed. Going public before those steps inverts the sequence Jesus gives. The stated goal remains gaining the brother, not exposing him.
Does Matthew 18 give local church leaders authority to exclude someone from membership?
The passage gives the gathered assembly a real judgment to make, but it describes the outcome as treating the unrepentant person as a Gentile or a tax collector, and it does not use the word membership. Jesus authorizes the gathered body to bind and release, and he says heaven ratifies what they bind and release, so the authority is genuine. It is also derivative, because it comes from Jesus, and remedial, because the aim is regaining the brother. Leaders should guard that aim and the surrounding call to forgive without limit rather than turning the passage into a license for shunning or public humiliation.
What does it mean that where two or three are gathered, Jesus is there?
Jesus promises his presence among even two or three gathered in his name, which assures the smallest legitimate gathering that he is in the middle of them. In context the promise follows the instruction about telling a matter to the assembly, so it comforts those who must make a hard judgment with the assurance that Jesus is present. It is not a formula for getting whatever a small group wants, because the verse before speaks of agreement in asking and the whole passage is bounded by the call to forgive. The promise is about his presence with those who gather under his name, not about the size or impressiveness of the group.
