Paul tells Titus to keep reminding believers that God’s saving grace must shape both their public conduct and the life of the church. Salvation rests entirely on God’s mercy, not on our righteous deeds, and that same grace leads believers to devote themselves to good works.

Paul begins with practical instruction for Christian life in society. Believers are to submit to rulers and authorities, to be obedient, and to be ready for every good work. They must not slander anyone. Instead, they are to be peaceable, gentle, and consistently courteous toward all people. This is more than social respectability. It is the kind of public conduct that fits those who have been saved by God’s grace.

Paul then explains why Christians must treat others this way: humility. Believers themselves were once in the same sinful condition as those still outside Christ. They too were foolish, disobedient, deceived, and enslaved to sinful desires and pleasures. Their lives were marked by evil, envy, hatred, and hostility toward one another. So Christians have no basis for pride or contempt. The contrast is clear—what we once were in sin, and what God has done for us in mercy.

That saving change did not come because of righteous deeds we had done, but because of God’s mercy. Paul states this plainly. Salvation is not earned by human goodness. God saved us through the washing of new birth and the renewing work of the Holy Spirit. The phrase “washing of regeneration” points chiefly to the Spirit’s inner cleansing and life-giving work at conversion, though the washing imagery naturally connects with baptism as its outward sign. In this context, however, baptism is not presented as the cause of salvation. Paul’s emphasis is on God’s saving action by mercy through the Spirit.

This saving work has a distinctly Trinitarian shape. God our Savior showed kindness and love for humanity. He saved us through the Holy Spirit, whom He poured out richly on us through Jesus Christ our Savior. As a result, believers have been justified by His grace and made heirs with the confident hope of eternal life. So the center of the passage is not moral improvement first, but God’s merciful saving work in Christ by the Spirit.

In verse 8, Paul calls this a trustworthy saying, most likely referring to the saving truths he has just stated in verses 4–7. Titus must insist on these things so that those who have believed God will be careful to devote themselves to good works. Paul does not set grace against obedience. In Titus, grace produces obedience. Good works do not save, but they are the proper fruit of salvation, and they are good and beneficial for people.

By contrast, Titus must avoid foolish controversies, genealogies, quarrels, and fights about the law. These disputes are useless and empty. They do not strengthen the church or encourage godly living. Paul then gives clear instruction about discipline: a divisive person is to be warned once and then again, and if he still persists, he is to be rejected. The issue is not merely that he holds a mistaken opinion, but that he is factious and disruptive in the church. At that point, his continued behavior shows that he is twisted by sin and knowingly persists in it.

Taken as a whole, this passage serves Titus’s larger task of helping establish healthy churches through sound doctrine and visibly good works. Christian conduct in society is grounded in salvation. God’s mercy in Christ should produce humble, peaceable, publicly visible goodness among believers. At the same time, church leaders must protect the church from fruitless teaching and persistent divisiveness. Grace and good works belong together, and the peace of the church must not be sacrificed by tolerating those who continually stir up division.
