The Bible clearly models a plurality of elders in each local church. Though it never suggests a specific number of elders for a particular congregation, the New Testament refers to “elders” in the plural in local churches (e.g., Acts 14:23; 16:4; 20:17; 21:18; Titus 1:5; James 5:14). When you read through Acts and the Epistles, there is always more than one elder being talked about.
