In each congregation, which has existed long enough to become fully organized, there is a plurality of elders or presbyters who serve as the governing body. These men are selected by the local congregations on the basis of qualifications set down in the scriptures (1 Timothy 3:1-8). Serving under the elders are deacons, teachers, and evangelists or ministers. The latter do not have the authority equal to or superior to the elders. The elders are shepherds or overseers who serve under the headship of Christ according to the New Testament, which is a kind of constitution. There is no earthly authority superior to the elders of the local church.
