Titus says to warn a divisive person once and then twice, and after that to have nothing more to do with him. The reason given is that such a person is warped and sinful and is self-condemned. See Titus 3:10–11.
In Titus 3:10–11, Paul tells Titus to take firm, limited steps with a person who keeps stirring up division. The process is measured: give a first warning and a second warning, then stop engaging with them. The reason is not personal irritation but an assessment of what their behavior shows. These lines come near the close of Titus, within a stretch of practical instruction about community life. Just before this, Paul urges believers to be ready for good works, to avoid quarrels, and to refuse pointless disputes (3:1–9).
Paul’s instruction treats persistent division as a serious threat to a Christian community’s health. The response is described as measured: there is a first warning and a second warning before any break in engagement. The issue is not framed as a single mistake but as a pattern that continues after correction.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Titus 3:10-11, then read the surrounding section so the answer stays connected to the passage's flow.
10Avoid a factious man after a first and second warning;
11knowing that such a one is perverted, and sins, being self-condemned.
