In the Presbyterian Church, local churches are managed and administered by a Kirk Session ("Session") and General Committee ("Committee").
Kirk Session comprises a teaching elder (or Minister) and ruling elders, who are voted in by the members of the church and serve for an unlimited period. Session members are de facto members of Committee, which also includes a number of church members who are voted in by the members of the church and serve for a fixed period, typically three years.
The Session is responsible for the spiritual welfare of the church. The Committee is responsible for all practical matters such as financial management, property management, rotas etc.
