From the beginning of the church, there were designated leaders. And though given various names (e.g., elders, pastors, overseers) they served the same function. As God-given leaders of God’s flock (Acts 20:28) and under-shepherds to the Chief Shepherd (1 Peter 5:1–4), these men were called to model the faith before God’s people and to teach the word of God, protecting God’s children from error and bolstering their faith in Christ.
A cursory reading of the New Testament shows how important these men were. In Acts we find elders in Jerusalem (11:30; 14:23; 15:2, 4, 6; 21:18) and Ephesus (20:17). When Paul planted churches in Galatia, he appointed elders in each church (Acts 14:23). In correspondence with Titus, he told him to appoint qualified overseers in the churches on Crete (Titus 1:5–9). Similarly, Timothy received instruction on the qualification of overseers (1 Timothy 3:1–7) and instructions for removing unqualified elders (5:17–23).
Even before Paul wrote his Pastoral Epistles, he had called churches to care for those who taught them (Galatians 6:6–9) and to honor those who led them (1 Thessalonians 5:12–13). Similarly, James, Peter, John, and the author of Hebrews all spoke in various ways about the office of the overseer/elder/pastor (see James 5:14; 1 Peter 5:1–4; 2 John 1; 3 John 1; Hebrews 13:7, 17). In short, the New Testament says a great deal about this important role, and it does so because the health of the church depends on those who lead them with God’s Word.
Yet, for all that it says about the office, we should ask another important question: Where do elders come from? Thankfully, the New Testament is not silent on this question. Just as it describes how to recognize an elder, it also describes where they come from. And faithful churches (and the elders who lead them), will be aware of how God raises up elders.
