The Greek adverb aperispastōs (from a- 'without' + perispaō 'to drag away/distract') means without distraction or undivided. Its single New Testament use describes the undistracted devotion that is possible for the celibate person.
Paul's argument in 1 Corinthians 7:35 uses aperispastōs to describe the gift of undistracted devotion to the Lord. He is not denigrating marriage but celebrating a particular calling: the person without family obligations can give their full attention to 'the Lord's affairs' without the holy tug-of-war that the married person faces. This rare word captures the monastic and apostolic ideal — not escape from the world, but unencumbered focus on the eternal. Every believer is called to some measure of aperispastōs attention amid life's legitimate distractions.
