The Scriptures establish two categories of office within the Church: Elders (also designated overseers or bishops, and pastor-teachers), and Deacons to lead and serve the flock under Christ (Philippians 1:1). Those who serve in these capacities must be qualified biblically (1 Timothy 3:1-13; Titus 1:5-9; 1 Peter 5:1-5). The elders-overseers-pastor-teachers who have been given a divinely delegated authority are especially accountable for the spiritual welfare of their Master's flock. He will judge not only them and their guidance of His sheep but also the flock's expected submission to their spiritual direction (Hebrews 13:7, 17).
