Reformed theology in the context of "Congregational polity"

Presbyterianism (pres-bə-TE-ree-a-nizm) is a historically Reformed Protestant tradition named after its form of church government by representative assemblies of elders, known as "presbyters". Though other Reformed churches are structurally similar, the word Presbyterian is applied to churches that trace their roots to the Church of Scotland or to English Dissenter groups that were formed during the English Civil War, 1642 to 1651.

Presbyterian theology typically emphasises the sovereignty of God, the authority of the Scriptures, and the necessity of grace through faith in Christ. Scotland ensured Presbyterian church government in the 1707 Acts of Union, which created the Kingdom of Great Britain. In fact, most Presbyterians in England have a Scottish connection. The Presbyterian denomination was also taken to North America, Australia, and New Zealand, mostly by Scots and Scots-Irish immigrants. Scotland's Presbyterian denominations hold to the Reformed theology of John Calvin and his immediate successors, although there is a range of theological views within contemporary Presbyterianism. Local congregations of churches that use Presbyterian polity are governed by sessions made up of representatives of the congregation (elders), a conciliar approach as with other levels of decision-making (presbytery, synod, and general assembly). There are roughly 75 million Presbyterians in the world.

In Reformed theology, the Lord's Supper or Eucharist is a sacrament that spiritually nourishes Christians and strengthens their union with Christ. The outward or physical action of the sacrament is eating bread and drinking wine. Reformed confessions, which are official statements of the beliefs of Reformed churches, teach that Christ's body and blood are really present in the sacrament and that believers receive, in the words of the Belgic Confession, "the proper and natural body and the proper blood of Christ." The primary difference between the Reformed doctrine and that of Catholic and Lutheran Christians is that for the Reformed, this presence is believed to be communicated in a spiritual manner by faith rather than by oral consumption. The Reformed doctrine of real presence is called "pneumatic presence" (from pneuma, a Greek word for "spirit"; alternatively called "spiritual real presence" or "mystical real presence").

Early Reformed theologians such as John Calvin and Heinrich Bullinger taught that Christ's person, including his body and blood, are presented to Christians who partake of it in faith. This view of the real spiritual presence was formally formulated by both Calvin and Bullinger in the Consensus Tigurinus. The historic Reformed confessions of faith, including the Second Helvetic Confession (Continental Reformed), Westminster Confession (Presbyterian), Thirty-Nine Articles (Anglican), and Savoy Declaration (Congregationalist), hold to the doctrine of real spiritual presence.

Protestant theology refers to the doctrines held by various Protestant traditions, which share some things in common but differ in others. In general, Protestant theology, as a subset of Christian theology, holds to faith in the Christian Bible, the Holy Trinity, salvation, sanctification, charity, evangelism, and the four last things.

Various Protestant denominations differ in their doctrine, with churches teaching either Wesleyan-Arminian theology, Reformed theology, or Baptist theology. Other evangelical bodies, such as the Lutheran Church–Missouri Synod, Presbyterian Church in America and the Evangelical Friends Church International may subscribe to what they see as the orthodox theology espoused by their historic tradition, such as Lutheranism, Presbyterianism or Quakerism respectively.

Under Charles I, the Puritans became a political force as well as a religious tendency in the country. Opponents of the royal prerogative became allies of Puritan reformers, who saw the Church of England moving in a direction opposite to what they wanted, and objected to increased Catholic influence both at Court and (as they saw it) within the Church.

After the First English Civil War political power was held by various factions of Puritans. The trials and executions of William Laud and then King Charles were decisive moves shaping British history. While in the short term Puritan power was consolidated by the Parliamentary armed forces and Oliver Cromwell, in the same years, the argument for theocracy failed to convince enough of the various groupings, and there was no Puritan religious settlement to match Cromwell's gradual assumption of dictatorial powers. The distinctive formulation of Reformed theology in the Westminster Assembly would prove to be its lasting legacy.

Baptist covenant theology, also known as 1689 Federalism or Baptist federalism, is a Baptist conceptual overview and interpretive framework for understanding the overall structure of the Bible. It sees the theological concept of a covenant as an organizing principle for Christian theology. The standard form of covenant theology views the history of God's dealings with mankind, from Creation to Fall to Redemption to Consummation, under the framework of three overarching theological covenants: those of redemption, of works, and of grace.

Covenentalists call these three covenants "theological" because, though not explicitly presented as such in the Bible, they are thought of as theologically implicit, describing and summarizing a wealth of scriptural data. Historical Reformed systems of thought treat classical covenant theology not merely as a point of doctrine or as a central dogma, but as the structure by which the biblical text organizes itself. The most well known form of covenant theology is associated with Presbyterians (paedobaptists) and comes from the Westminster Confession of Faith. Baptist covenant theology (credobaptist) is distinct from Westminsterian covenant theology, and finds its most influential expression in the Second London Confession of Faith of 1689.
