Congregationalist polity in the context of "Presbyterian synod"

Baptists are a Protestant tradition of Christianity distinguished by baptizing only believers (believer's baptism) and doing so by total immersion. Modern Baptist churches generally subscribe to the doctrines of soul competency (the responsibility and accountability of every person before God), sola fide (justification by faith alone), sola scriptura (the Bible as the sole infallible authority) and congregationalist ecclesiastical polity. Baptists generally recognize at least two sacraments or ordinances: Baptism and the Lord's Supper.

Diverse from their beginnings, those identifying as Baptists today may differ widely from one another in what they believe, how they worship, their attitudes toward other Christians, and their understanding of what is important in Christian discipleship. Baptist missionaries have spread various Baptist churches to every continent. The largest Baptist communion of churches is the Baptist World Alliance, and there are many different groupings of Baptist churches and Baptist congregations.

Congregationalism (also Congregational Churches or Congregationalist Churches) is a Reformed Christian (Calvinist) tradition of Protestant Christianity in which churches practice congregational government. Each congregation independently and autonomously runs its own affairs. These principles are enshrined in the Cambridge Platform (1648) and the Savoy Declaration (1658), Congregationalist confessions of faith. The Congregationalist Churches are a continuity of the theological tradition upheld by the Puritans. Their genesis was through the work of Congregationalist divines Robert Browne, Henry Barrowe, and John Greenwood.

In the United Kingdom, the Puritan Reformation of the Church of England laid the foundation for such churches. In England, early Congregationalists were called Separatists or Independents to distinguish them from the similarly Calvinistic Presbyterians, whose churches embraced a polity based on the governance of elders; this commitment to self-governing congregations was codified in the Savoy Declaration. Congregationalism in the United States traces its origins to the Puritans of New England, who wrote the Cambridge Platform of 1648 to describe the autonomy of the church and its association with others. Within the United States, the model of Congregational churches was carried by migrating settlers from New England into New York, then into the Old Northwest, and further.

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.
