Presbyterian polity

Presbyterian or presbyteral polity is a method of church governance ("ecclesiastical polity") typified by the rule of assemblies of presbyters, or elders. Each local church is governed by a body of elected elders usually called the session (or consistory), though other terms, such as church board, may apply. Groups of local churches are governed by a higher assembly of elders known as the presbytery or classis; presbyteries can be grouped into a synod, and presbyteries and synods nationwide often join together in a general assembly. Responsibility for conduct of church services is reserved to an ordained minister or pastor known as a teaching elder, or a minister of the word and sacrament.

Presbyterian polity was developed as a rejection of governance by hierarchies of single bishops (episcopal polity), but also differs from the congregationalist polity in which each congregation is independent. In contrast to the other two forms, authority in the presbyterian polity flows both from the top down (as higher assemblies exercise limited but important authority over individual congregations, e.g., only the presbytery can ordain ministers, install pastors, and start up, close, and approve relocating a congregation) and from the bottom up (e.g., the moderator and officers are not appointed from above but are rather elected by and from among the members of the assembly). This theory of governance developed in Geneva under John Calvin and was introduced to Scotland by John Knox after his period of exile in Geneva. It is strongly associated with French, Dutch, Swiss and Scottish Reformation movements, and the Reformed and Presbyterian churches.

Among the early church fathers, it was noted that the offices of elder and bishop were identical, and were not differentiated until later, and that plurality of elders was the norm for church government. St. Jerome (347–420) "In Epistle Titus", vol. iv, said, "Elder is identical with bishop; and before the urging of the devil gave rise to factionalism in religion, so much that it was being said among the people, 'I am of Paul, I of Apollos, I of Cephas', the churches were governed by a joint council of elders. After it was... decreed throughout the world that one chosen from among the presbyters should be placed over the others." This observation was also made by Chrysostom (349–407) in "Homilia i, in Phil. i, 1" and Theodoret (393–457) in "Interpret ad. Phil. iii", 445.

Aerius of Sebaste also attacked the episcopal polity in the 4th century.

Presbyterianism was first described in detail by Martin Bucer of Strasbourg, who believed that the early Christian church implemented presbyterian polity. The first modern implementation was by the Geneva church under the leadership of John Calvin in 1541.

In the early days of the Scottish Reformation there were Superintendents. There were also Tulchan Bishops and Archbishops. Much of the history of the Church of Scotland and the nation itself is bound up with the relation between Episcopalianism, which the Protestant monarchs favoured, and the Presbyterianism of the reformers. In the Hungarian Reformed Church there remain bishops who have a superintending role.

Presbyterian polity is constructed on specific assumptions about the form of the government intended by the Bible:

Presbyterianism uses a conciliar method of church government (that is, leadership by the group or council). Thus, the ministers and "elders" govern together as a group, and at all times the office is for the service of the congregation, to pray for them and to encourage them in the faith. The elders together exercise oversight (episcopacy) over the local congregation, with superior groups of elders gathered on a regional basis exercising wider oversight.
