The Greek noun zētēsis (ζήτησις) means a seeking, inquiry, questioning, debate, controversy. It appears seven times in the NT (John 3:25; Acts 15:2, 7; 25:20; 1 Tim 6:4; 2 Tim 2:23; Titus 3:9). The word derives from zēteō (to seek) and can range from legitimate inquiry to fruitless dispute.
The NT uses zētēsis in both neutral and negative senses. In Acts 15:2, the 'debate' (zētēsis) over circumcision at Antioch led to the Jerusalem Council — a productive controversy that clarified the gospel. But in the Pastoral Epistles, Paul consistently warns against zētēsis of the wrong kind: 'foolish and ignorant controversies' that 'breed quarrels' (2 Tim 2:23), disputes about 'words' that produce 'envy, dissension, slander' (1 Tim 6:4), and 'foolish controversies, genealogies, dissensions, and quarrels about the law' that are 'unprofitable and worthless' (Titus 3:9). The distinction is key: seeking truth is noble; seeking argument is destructive.
