Reformed churches in the context of Elder (Presbyterian)

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.

In the early 17th century, thousands of English Puritans settled in North America, almost all in New England. Puritans were intensely devout members of the Church of England who believed that the Church of England was insufficiently reformed, retaining too much of its Roman Catholic doctrinal roots, and who therefore opposed royal ecclesiastical policy. Most Puritans were "non-separating Puritans" who believed there should be an established church and did not advocate setting up separate congregations distinct from the Church of England; these were later called Nonconformists. A small minority of Puritans were "separating Puritans" who advocated for local, doctrinally similar, church congregations but no state established church. The Pilgrims, unlike most of New England's puritans, were a Separatist group, and they established the Plymouth Colony in 1620. Puritans went chiefly to New England, but small numbers went to other English colonies up and down the Atlantic.

Puritans played the leading roles in establishing the Massachusetts Bay Colony in 1629, the Saybrook Colony in 1635, the Connecticut Colony in 1636, and the New Haven Colony in 1638. The Colony of Rhode Island and Providence Plantations was established by settlers expelled from Massachusetts because of their unorthodox religious opinions. Puritans were also active in New Hampshire before it became a crown colony in 1691. Puritanism as a powerful force weakened early in the 18th century and before 1740 was replaced by the much milder Congregational church.

The Synod of Dort (also known as the Synod of Dordt or the Synod of Dordrecht) was a European transnational Synod held in Dordrecht in 1618–1619, by the Dutch Reformed Church, to settle a divisive controversy caused by the rise of Arminianism. The first meeting was on 13 November 1618 and the final meeting, the 154th, was on 9 May 1619. Voting representatives from eight foreign Reformed churches were also invited. Dort was a contemporary Dutch term for the town of Dordrecht (and it remains the local colloquial pronunciation).

In 2014, the first entire critical edition of the Acts and Documents of the Synod was published.

The reformed confessions of faith are the confessional documents of various Reformed churches. These express the doctrinal views of the churches adopting the confession. Confessions play a crucial part in the theological identity of reformed churches, either as standards to which ministers must subscribe, or more generally as accurate descriptions of their faith. Most confessions date to the 16th and 17th century.

Catechisms, canons, theses and other such documents may not be confessions per se, yet these still serve as symbols of the reformed faith.

The Confession of Faith, popularly known as the Belgic Confession, is a confession to which many Reformed churches subscribe as a doctrinal standard. The Confession forms part of the Three Forms of Unity, which are the official subordinate standards of the Dutch Reformed Church. The confession's chief author was Guido de Brès, a Walloon Reformed pastor, active in the Low Countries, who died a martyr to the faith in 1567, during the Dutch Reformation. The name Belgic Confession follows the 17th-century Latin Confessio Belgica. Belgica referred to the whole of the Low Countries, both north and south, which today is divided into the Netherlands and Belgium.
