Government
The term Presbyterian comes from the Greek word "presbuteros" which means "elder". One of the distinctive aspects of the Presbyterian Church is that it is a representative, Elder-led form of government. Ruling Elders and Teaching Elders (that is, pastors) are Ordained to share the leadership of the congregation. Meetings of the Elders are moderated by the Pastor and recorded by the Clerk of Session. (Interested in more? See Book of Order: Form of Government which meticulously outlines the government of the Presbyterian Church.

• Elders
  The congregation elects individuals from among its active members to the office of elder. Each year five Elders are elected to serve a 3-year term on the board of Elders (called "the Session"); thus there are 15 Elders serving on the Session each year.
  
  The Elders are entrusted with the oversight of the congregation with the Pastor, and serve as committee chairs and participants in the following committees: Christian Education, Church Growth and Outreach, Facilities, Personnel, Stewardship/Finance and Worship. A Nominating Committee (consisting of two Elders and other appointed members of the congregation) assists the congregation in suggesting names for prospective Elders.
• Deacons
  The office of deacon as set forth in Scripture is one of sympathy, witness, and service after the example of Jesus Christ. It is the duty of deacons, first of all, to minister to those who are in need, to the sick, to the friendless, and to any who may be in distress both within and beyond the community of faith.
  
  Deacons serve on the following committees: Congregational Care, Christian Service & Action, Fellowship, and New Member ministry teams.
