One of the most defining elements of the Brethren is the rejection of the concept of clergy. Their view is that all Christians are ordained by God to serve and therefore all are ministers, in keeping with the doctrine of the priesthood of all believers. The Brethren embrace the most extensive form of that idea, in that there is no ordained or unordained person or group employed to function as minister(s) or pastors. Brethren assemblies are led by the local church elders within any fellowship.
