This adjective describes someone who is quick-tempered or irascible—prone to anger and given to outbursts. In Titus 1:7, Paul lists disqualifications for elders: 'For an overseer, as God's steward, must be above reproach. He must not be arrogant or quick-tempered.' The term indicates not occasional anger but a temperamental tendency—someone whose anger flares easily and frequently. Such volatility disqualifies one from shepherding God's people, who need patient, measured leadership, not explosive reactions.
