Many congregations have a committee to assist and work with the professional minister or ministers.
An older model is the Ministerial Relations Committee, which tends to be an advocate for, and a support and guidance group to, the minister or ministers. The focus of these groups generally is limited to professional ministers, rather than to the overall state of the congregation's ministry. In unhealthy congregations, this model can lead to triangulation.
A newer model is the Committee on Ministry (CoM), which focuses on all aspects of the congregation's ministry, including professional leadership, music, social justice, religious education, pastoral care, and so on. This model helps the congregation make sure that its ministries are serving its mission and vision using a whole-church assessment model.
In practice, congregations have used the names interchangeably, so some congregations have creatively tweaked the name (e.g. Committee on Shared Ministries) to distinguish the difference.
An excellent description of the Committee on Ministry Model is described in Robert Latham's book Moving on from Church Folly Lane: The Pastoral to Program Shift.
