The Bible teaches that the church is led by Elders. Elders are responsible for the spiritual oversight and governance of the congregation. In the Presbyterian form of church government, elders are also delegates to the higher courts of Presbytery and Synod.


Deacons are responsible for the ministry of mercy for the congregation and the community, and take care of the church's facilities.
