Titus 3:9
9but shun foolish questionings, genealogies, strife, and disputes about the law; for they are unprofitable and vain.
But shun foolish questionings, genealogies, strife, and disputes about the law; for they are unprofitable and vain. The “but” sets this against the profitable good works of v. 8. Not every religious argument is obedience.
Controversy can be a way of resisting the mercy just preached. The Spirit enables a holy refusal of worthless talk; the church can still dive in and call it zeal. Profit is the test Paul just used: good works help people; these fights do not.
Calvin will soon forbid wasting much time in debate with heretics. Here the catalog is foolish questions, genealogies, dissensions, legal quarrels—unprofitable and worthless. The trustworthy saying (v. 8) is not served by this diet.
God feeds His people on mercy and good works, not on speculative fights. Avoidance is obedience. The law-quarrels of Crete are not a higher spirituality; they are a substitute for the regeneration just described.
