WHAT IS THE ROLE OF AN ELDER?

According to the Brit Hadasha (New Covenant), elders are responsible for the primary leadership and oversight of a congregation. The congregational leader is the head elder.  The function and role of an elder is well summarized by Alexander Strauch in his book Biblical Eldership: "Elders lead the congregation [1 Tim 5:17Titus 1:71 Peter 5:1-2], teach and preach the Word [1 Timothy 3:22 Timothy 4:2Titus 1:9], protect the body from false teachers [Acts 20:1728-31], exhort and admonish the saints in sound doctrine [1 Timothy 4:132 Timothy 3:13-17Titus 1:9], visit the sick and pray [James 5:14Acts 20:35], and judge doctrinal issues [Acts 15:16]. In biblical terminology, elders shepherd, oversee, lead, and care for the local congregation" (16).
