Reformed Presbyterian Church General Assembly

Presbyterianism is a part of the Reformed tradition within Protestantism that broke from the Roman Catholic Church. Presbyterian churches derive their name from the presbyterian form of church government by representative assemblies of elders. Many Reformed churches are organised this way, but the word Presbyterian, when capitalized, is often applied to churches that trace their roots to the Church of Scotland or to English Dissenter groups that formed during the English Civil War.

The Presbyterian Church (USA), abbreviated PC (USA), is a mainline Protestant denomination in the United States. It is the largest Presbyterian denomination in the country, known for its liberal stance on doctrine and its ordaining of women and members of the LGBT community as elders and ministers. The Presbyterian Church (USA) was established with the 1983 merger of the Presbyterian Church in the United States, whose churches were located in the Southern and border states, with the United Presbyterian Church in the United States of America, whose congregations could be found in every state.

The Presbyterian Church in America (PCA) is the second-largest Presbyterian church body, behind the Presbyterian Church (USA), and the largest conservative Calvinist denomination in the United States. The PCA is Reformed in theology and presbyterian in government.

The Cumberland Presbyterian Church is a Presbyterian denomination spawned by the Second Great Awakening. In 2019, it had 65,087 members and 673 congregations, of which 51 were located outside of the United States. The word Cumberland comes from the Cumberland River valley where the church was founded.

The Presbyterian Church in the United States was a Protestant denomination in the Southern and border states of the United States that existed from 1861 to 1983. That year, it merged with the United Presbyterian Church in the United States of America (UPCUSA) to form the Presbyterian Church (USA).

The United Presbyterian Church in the United States of America (UPCUSA) was the largest branch of Presbyterianism in the United States from May 28, 1958, to 1983. It was formed by the union of the Presbyterian Church in the United States of America (PCUSA), often referred to as the "Northern" Presbyterian Church, with the United Presbyterian Church of North America (UPCNA), a smaller church of Covenanter-Seceder tradition at a conference in downtown Pittsburgh, Pennsylvania, in May 1958. Vigorous ecumenical activity on the part of PCUSA leaders led to this merger, something of a reunion of two long-separated branches of the larger Presbyterian family deriving from the British Isles.

The Evangelical Presbyterian Church (EPC) is an American church body holding to presbyterian governance and Reformed theology. It is most distinctive for its approach to the way it balances certain liberties across congregations on "non-essential" doctrines, such as egalitarianism in marriage or the ordination of women, alongside an affirmation of core "essential" doctrinal standards.

The Presbyterian Church in the United States of America (PCUSA) was the first national Presbyterian denomination in the United States, existing from 1789 to 1958. In that year, the PCUSA merged with the United Presbyterian Church of North America, a denomination with roots in the Seceder and Covenanter traditions of Presbyterianism. The new church was named the United Presbyterian Church in the United States of America. It was a predecessor to the contemporary Presbyterian Church (USA).

The Bible Presbyterian Church is an American Protestant denomination in the Calvinist tradition.

The fundamentalist–modernist controversy is a major schism that originated in the 1920s and 1930s within the Presbyterian Church in the United States of America. At issue were foundational disputes about the role of Christianity; the authority of the Bible; and the death, resurrection, and atoning sacrifice of Jesus Christ. Two broad factions within Protestantism emerged: fundamentalists, who insisted upon the timeless validity of each doctrine of Christian orthodoxy; and modernists, who advocated a conscious adaptation of the Christian faith in response to the new scientific discoveries and moral pressures of the age. At first, the schism was limited to Reformed churches and centered around the Princeton Theological Seminary which had fundamentalist faculty members found Westminster Theological Seminary when Princeton went in a liberal direction. However, it soon spread, affecting nearly every Protestant denomination in the United States. Denominations that were not initially affected, such as the Lutheran churches, eventually were embroiled in the controversy, leading to a schism in the United States.

ECO: A Covenant Order of Evangelical Presbyterians is an evangelical Presbyterian denomination in the United States. As a Presbyterian church, ECO adheres to Reformed theology and Presbyterian polity. It was established in 2012 by former congregations and members of the Presbyterian Church (USA), abbreviated PC(USA). Denominational disputes over theology—particularly ordination of practicing homosexuals as pastors and gay marriage—and bureaucracy led to the founding of ECO. In 2018, ECO has over 383 congregations, 103,425 covenant partners and over 500 pastors. ECO churches are egalitarian in beliefs and ordain women as pastors and elders.

The National Presbyterian Church in Mexico is the second-largest Protestant church, and the largest Reformed denomination in Mexico. It is present throughout the country, and is particularly strong in the states of Tabasco, Chiapas, Campeche, Yucatan, Nuevo León, Aguascalientes and Mexico City.
