Each congregation of the Lord’s church is autonomous (self-governing). We have no earthly headquarters, but get our instructions from the Bible only. Elders are men who meet the qualifications found in 1 Timothy 3 and Titus 1, and they are selected by members of the congregation to serve.
Duties of elders include:
1) Overseeing the work (Acts 20:28),
2) Feeding the flock (Acts 20:28),
3) Watching for the souls (Hebrews 13:17) and
4) Being examples to the flock (1 Peter 5:3).
The elders are held accountable to God to see that only the Bible is taught for doctrine. All other doctrine is false and will cause men to lose their souls.
