The Elders and Pastors together form the Session, the governing body for the local church. As identified in the Book of Order (the Constitution of the Presbyterian Church U.S.A.), the Session is given the authority and responsibilities to lead and direct the entire ministry of the church. Either men and women may serve as officers.
At Westminster Presbyterian Church , the Session is comprised of 12 elders, divided among three classes based on end of term. Elders are elected annually at a meeting of the congregation.
