Titus says to avoid foolish controversies, genealogies, dissensions, and quarrels about the law. He calls them unprofitable and worthless. See Titus 3:9.
In Titus 3:9 Paul tells Titus to deliberately avoid certain kinds of debates. He lists “foolish questions,” talk about genealogies, strife, and conflicts focused on the law. His reason is practical: these conversations do not produce anything useful and end up being empty. This line sits inside Titus’s closing set of practical instructions about community life and public behavior. Just before it, Paul urges believers to be ready for good works and to show gentleness toward everyone, grounding that posture in God’s kindness shown to them (3:1–8).
Titus 3:9 names a category of talk that is not worth a Christian community’s time: debates that spiral into heat rather than help.
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 3:9, then read the surrounding section so the answer stays connected to the passage's flow.
