Teaching and ruling elders are ordained and convene in the lowest council known as a session or consistory responsible for the discipline, nurture, and mission of the local congregation. Teaching elders (pastors or ministers) have responsibility for teaching, worship, and performing sacraments. Pastors or ministers are called by individual congregations. A congregation issues a call for the pastor or minister's service, but this call must be ratified by the local presbytery. The pastor or minister is a teaching elder, and Moderator of the Session, but is not usually a member of the congregation; instead, this person is a member of the Presbytery of which the given church is a member.
