Matthew 18:18 Commentary: Binding and Loosing

Matthew 18 sits within Jesus’ instruction to his disciples on life in the kingdom community. The immediate context (vv.15, 17) outlines a process for addressing sin among believers: private correction, then taking witnesses, then bringing the matter before the assembled church. Verse 18 then supplies the theological foundation for those actions.

First-century Judaism used “bind and loose” as technical terms. Rabbis would “bind” what the Torah forbade and “loose” what it permitted. Jesus adopts this language, but his disciples are not merely interpreting law; they are administering the fellowship of the new covenant. The fact that Jesus repeats this promise to all twelve disciples (not only Peter, as in Matthew 16:19) signals that the authority extends to the apostolic band and, by extension, to the church acting in their tradition.

The setting is also significant. Jesus has been teaching about humility, receiving “little ones,” and confronting sin. The church (v.17, ἐκκλησία) is the community where these hard conversations happen. Jewish synagogues had discipline procedures, including rebuke and excommunication. Jesus now authorises his own assembly to do the same, with the assurance that its sentences are taken seriously in heaven. This is not a blank cheque for any church decision, but a promise that when the church acts by his teaching and in his name, the Father backs its judgment.

The consulted sources note no significant textual variants for Matthew 18:18. The wording is stable across the major manuscript families, and the verse is well attested.

In the early church, this verse was often cited in debates about church discipline and the authority of bishops. Cyprian of Carthage used it to argue for unity under the bishop. During the medieval period, it became a foundation for papal claims to bind and loose both sins and doctrine, a development challenged at the Reformation. Martin Luther and John Calvin insisted that the power of the keys was ministerial, dependent on the word of God, not vested in a person. The Reformed tradition, following Calvin, distinguished the doctrinal binding and loosing (Matthew 16) from the disciplinary binding and loosing (Matthew 18). In modern ecumenical dialogues, the verse surfaces in discussions about church order, excommunication, and the role of the congregation in decision-making.

Three-point outline

1. The Authority of the Church. Jesus gives the community of disciples the power to bind and loose. This echoes the earlier grant to Peter but is here extended to all. Your decisions in church discipline carry divine weight.
2. Heaven Ratifies Earthly Decisions. The future perfect tense (“will have been bound”) indicates that heaven has already confirmed what the church, acting faithfully, decides. This is not a cause for pride but for sober responsibility.
3. Restoration Is the Goal. The whole context (vv.15, 20) aims not at punishment but at “gaining your brother” (v.15). Binding and loosing serves the end of repentance, forgiveness, and reinstatement.

Five-point outline

1. Begin with private confrontation (v.15).
2. Escalate with witnesses (v.16).
3. Bring the matter before the church (v.17).
4. Pronounce binding or loosing, with confidence that heaven concurs (v.18).
5. Pray together, trusting Christ’s presence in the assembly (vv.19, 20).

Illustration hooks

• A church board struggles over whether a member whose lifestyle contradicts Christian teaching should be removed. They weigh love and truth, unsure what to decide. This verse says: act in humility, follow the process, and trust that God stands behind your decision.
• A teenager has been caught stealing from the church offering. The leadership follows the steps of Matthew 18, private talk, then witnesses, then a meeting. The family feels judged, but the church says, “We do this because we want you restored, not discarded.” Binding and loosing is about healing.

Questions your congregation is asking

• Does God really back everything a church decides, even when leaders make mistakes?
• Is Matthew 18:18 about church discipline only, or does it also apply to doctrinal debates (e.g., what is permissible for Christians)?
• If this authority was given to the apostles, does it still apply to churches today?

This verse is the hinge between Jesus’ instructions on confronting sin (vv.15, 17) and his promise about prayer and his presence (vv.19, 20). It connects the hard work of discipline with the confidence that heaven is involved.

Discussion questions

1. Read Matthew 18:15, 20. Why do you think Jesus frames church discipline with this promise about binding and loosing?
2. The phrase “bind and loose” would have sounded familiar to first-century Jews. What did it mean in rabbinic circles, and how does Jesus use it differently?
3. Look at verse 18 in the YLT: “shall be having been bound” and “shall be having been loosed.” What does the future perfect tense suggest about the relationship between earth and heaven?
4. Some say this authority was given only to the apostles; others say it belongs to the whole church. What do you think, and why? How does the context of v.17 (“tell it to the assembly”) affect your answer?
5. How can a church misuse this promise? What safeguards does Jesus build into the context to prevent abuse?
6. Does binding and loosing apply only to exclusion (excommunication), or also to welcoming people back? How does that fit with the overall goal of Matthew 18?
7. How does knowing that Christ is present “where two or three are gathered” (v.20) change the way you view difficult church decisions?
