Acts 15:39 & Matt 18:15-17 dispute link?
How does Acts 15:39 connect with Matthew 18:15-17 on resolving disputes?

Setting the Scene

Acts 15:39 records “such a sharp disagreement” between Paul and Barnabas that “they parted company”.

Matthew 18:15-17 lays out Jesus’ step-by-step pattern for dealing with offenses: private confrontation, one or two witnesses, then the church, and finally separation if unrepentant.

• Both passages address conflict among believers; together they form a fuller picture of how Christians should handle disputes.


Looking Closely at Acts 15:39

“Barnabas took Mark and sailed for Cyprus.”

—No moral sin is mentioned, only intense disagreement over ministry strategy (cf. Acts 13:13; 15:37-38).

—“Sharp” shows real emotion, yet no name-calling, gossip, or violence is recorded.

—Both men continue serving the Lord immediately, implying no bitterness that hindered ministry (cf. Acts 15:40-41).


Reviewing Matthew 18:15-17

1. “If your brother sins against you, go and confront him privately.”

2. “If he will not listen, take one or two others along.”

3. “If he refuses to listen to them, tell it to the church.”

4. Persistent refusal leads to relational distance: “treat him as you would a pagan or a tax collector.”

—The goal in every step is restoration, not winning an argument (Galatians 6:1).


How the Two Passages Interlock

• Private Dialogue: Paul and Barnabas evidently followed step one. Scripture mentions only their direct conversation; no third parties appear until after they decide to separate.

• Matters of Conscience vs. Moral Sin: Matthew 18 targets overt sin. Acts 15 shows a disagreement over wisdom and personnel. Romans 14:1-4 teaches liberty in such areas; thus they could agree to disagree without labeling the other as sinful.

• Peaceable Separation: When consensus proved impossible, they parted for the sake of the mission, paralleling Matthew 18’s last resort—parting fellowship when unity cannot be maintained.

• Mutual Respect Maintained: Antioch’s believers “commended” Paul and Silas (Acts 15:40). No discipline was enacted; both teams received church blessing, suggesting the church recognized the dispute was not moral but practical.

• Later Reconciliation: Years later Paul writes, “Get Mark and bring him with you, for he is useful to me for ministry” (2 Timothy 4:11; cf. Colossians 4:10). The Matthew 18 spirit of restoration ultimately prevailed.


Practical Takeaways for Today

• Address conflict early and face-to-face.

• Distinguish between sin that demands repentance and honest differences in judgment.

• If agreement proves impossible, part ways without hostility, trusting God to work through each party.

• Keep the door open for future reconciliation; today’s “sharp disagreement” need not be tomorrow’s permanent division.

• Maintain a gospel focus: both teams multiplied ministry rather than stalling it. That remains the biblical priority (Philippians 1:18).
