These groups of elders make decisions for the local parish through a ruling body called the Kirk session (Latin. sessio from sedere "to sit"), sometimes the Session, church session, or (in Continental Reformed usage) consistory. The members of the session are the pastor of that congregation, and the other ruling elders (sometimes called "lay elders". In most denominations, the pastor serves as Moderator and thus convenes or presides over the session. All elders have an equal vote in the session. In some denominations, the pastor is given no vote, however in a sitting body of an even number or with a quorum of the session counted he or she can break a tie with a casting vote. In the Polity of the Presbyterian Church (USA), the pastor and associate pastor have a vote as members of the session on any and all matters; however, oftentimes he or she refrains from voting except in tie situations. The Pastor is not a voting member of the congregation.
The elders who are members of Session have both executive powers as a group and pastoral responsibility. Many elders will be in regular pastoral contact with a group of the members of the congregation and their families. In the pastoral function elders rarely bring issues to Session meetings, resolving them privately or with the aid of the minister or other counsellor.
In executive function a number of Sessions have complete authority (under presbytery) for the ordering of all business, spiritual and temporal, of their congregation. This condition is known in the Church of Scotland as "quoad omnia". Other congregations have a separate "Congregational Board", "Deacons' court" or "Management Committee" which deals with financial details and the maintenance of property. The financial board thus relieves the Session of much routine responsibility but remains under the direction of the Session. Kirk Sessions remain the first court of the presbyterian church. They are under the jurisdiction of the presbytery of the bounds to which they commission the minister and at least one ruling elder. The minister is not a member of the congregation but of the presbytery, thus he or she is under the spiritual oversight of the presbytery. The members of the congregation, including the ruling elders, are under the spiritual oversight of the Kirk Session.
The person who takes minutes for the Session is known as the "Session Clerk".
