Presbyterian church history began during the sixteenth-century Protestant Reformation, rooted in John Calvin's Geneva and established in Scotland by John Knox. Defined by government through elected elders (presbyters) and reformed covenant theology, Scots-Irish immigrants brought the tradition to North America, where it played a major role in the American Revolution and national education.
Foundations of Presbyterian church history: Calvin's Geneva and Knox's Scotland
The origins of Presbyterianism are rooted in the Swiss Reformation led by French theologian John Calvin. In Geneva during the 1530s through 1560s, Calvin developed a systematic biblical theology articulated in his magnum opus, Institutes of the Christian Religion. Calvin emphasized the supreme sovereignty of God, the absolute authority of Holy Scripture, double predestination, and the covenantal structure of redemption. Learn more about his theology in our guide to John Calvin and Calvinism explained.
Crucially, Calvin designed a representative form of church government based on the New Testament Greek term presbyteros, meaning elder. Rather than top-down monarchical bishops (episcopacy) or autonomous direct democracy (congregationalism), Calvin established a graded hierarchy of representative courts. Local congregations were guided by a session of teaching elders (ministers) and ruling elders (lay leaders elected by the congregation), who answered to regional synods.
Among the Marian exiles who found sanctuary in Geneva was Scottish Catholic priest turned Protestant reformer John Knox. Knox marveled at Geneva, declaring it "the most perfect school of Christ since the days of the Apostles." Returning to Scotland in 1559, Knox spearheaded the Scottish Reformation. In 1560, the Scottish Parliament abolished papal jurisdiction, approved the Scots Confession, and adopted Knox's First Book of Discipline, establishing the Church of Scotland (known as the Kirk) as a national Presbyterian communion.
Over the following century, Scottish Presbyterians fiercely defended their church government against English monarchs who sought to impose royal supremacy and Anglican bishops. In 1638, thousands of Scots signed the National Covenant, pledging loyalty to Christ as the sole King and Head of the Church. During the brutal persecution of the 1680s known as the "Killing Time," faithful Covenanters gathered in secret outdoor field assemblies called conventicles among the heather and glens, facing imprisonment, torture, and execution on the gallows rather than surrender their Presbyterian polity.
During the English Civil War in the 1640s, the English Parliament summoned the Westminster Assembly of Divines to the cloisters of Westminster Abbey. Working alongside Scottish commissioners from 1643 to 1649, the assembly produced the Westminster Confession of Faith, the Westminster Shorter Catechism, and the Larger Catechism. These historic documents became the constitutional doctrinal standards of English-speaking Presbyterianism, defining the core principles of what Presbyterians believe and detailed in our guide to the Westminster Confession of Faith.
Colonial America: Scots-Irish immigration and Francis Makemie
Presbyterianism arrived in North America primarily through the great eighteenth-century migration of Ulster Scots, commonly known as the Scots-Irish. In the early seventeenth century, King James I had settled thousands of Scottish Lowland Presbyterians in northern Ireland. Facing severe economic rents, crop blights, and religious discrimination under Anglican sacramental test oaths, more than 200,000 Scots-Irish departed Ireland for the American colonies between 1717 and 1775.
Arriving at ports along the Delaware River, these Scots-Irish immigrants pushed directly toward the colonial frontier, establishing homesteads along the Appalachian valleys of central and western Pennsylvania, the Shenandoah Valley of Virginia, and the Carolina backcountry. Fiercely independent and deeply pious, they built log meetinghouses that served as community centers, defensive forts, and classical grammar schools, embedding Presbyterian faith across the American wilderness.
The pioneer missionary who organized these scattered settlers was Francis Makemie, an energetic Irish-born Presbyterian evangelist who arrived in the Chesapeake Bay region in 1683. Makemie traveled on horseback and by boat throughout Maryland, Virginia, Delaware, and Pennsylvania, preaching and gathering congregations. In 1707, Makemie was arrested in New York by the royal Anglican governor, Lord Cornbury, for preaching without a royal license. Makemie skillfully defended his rights as a free Englishman under the Toleration Act of 1689. His jury acquittal was celebrated throughout the colonies as a historic milestone for American religious freedom.
In the spring of 1706, Makemie convened seven ministers in Philadelphia to establish the Presbytery of Philadelphia, the first presbytery organized on American soil. By 1716, rapid congregational growth necessitated the creation of the Synod of Philadelphia, composed of four regional presbyteries. In 1729, the synod adopted the Westminster Standards through the famous Adopting Act, which established the principle of "scrupling—llowing candidates for ordination to declare reservations on non-essential matters while affirming the substance of the confession.
The Great Awakening: Old Side vs. New Side
During the 1730s and 1740s, the religious revival known as the First Great Awakening swept through the American colonies, precipitating the first major schism in American Presbyterianism. Evangelist George Whitefield and New Jersey Presbyterian pastor Gilbert Tennent preached fervent outdoor revival sermons, demanding that ministers and congregants demonstrate proof of inward spiritual regeneration.
Gilbert's father, William Tennent, established the famous "Log College" in Neshaminy, Pennsylvania, in 1726, an unaccredited log cabin academy that trained dozens of zealous revivalist preachers. Traditionalists in the Synod of Philadelphia, known as the "Old Side," opposed these revivalist preachers, criticizing their emotionalism, their violation of parish boundaries, and their lack of formal European university degrees. The revivalists, known as the "New Side," accused Old Side ministers of dead orthodoxy, epitomized by Gilbert Tennent's inflammatory 1740 sermon, The Danger of an Unconverted Ministry.
In 1741, the synod ruptured into the Old Side Synod of Philadelphia and the New Side Synod of New York. In 1746, New Side leaders established the College of New Jerse—hich later became Princeton Universit—o unite rigorous classical education with living evangelical piety. In 1758, the two sides reconciled and formed the Synod of New York and Philadelphia on the basis of the Westminster Standards.
Presbyterians and the American Revolution: John Witherspoon
In 1768, the College of New Jersey called eminent Scottish minister and moral philosopher John Witherspoon to serve as its sixth president. Witherspoon transformed Princeton into a premier intellectual incubator for colonial leaders. His students included future president James Madison, twenty-one United States senators, thirty-nine representatives, three Supreme Court justices, and nine Continental Congress delegates.
Witherspoon emerged as a leading champion of colonial independence, arguing that civil liberty and religious liberty were inseparable. In 1776, Witherspoon served in the Continental Congress and became the only active clergyman to sign the Declaration of Independence. Across the Atlantic, British authorities viewed the rebellion as an insurrection led by Calvinists; King George III reportedly commented, "Cousin America has run off with a Presbyterian parson," and Prime Minister Horace Walpole quipped that all the colonies had run away with a Presbyterian dominie.
In 1789, the same year George Washington was inaugurated under the new United States Constitution, Presbyterian delegates met in Philadelphia under Witherspoon's moderation to organize the General Assembly of the Presbyterian Church in the United States of America (PCUSA), adopting a national church constitution modeled directly on representative republican governance.
Nineteenth-century divisions: Old School vs. New School
During the early nineteenth century, Presbyterians expanded aggressively into the western frontier. In 1801, the PCUSA adopted the Plan of Union with New England Congregationalists, allowing frontier settlements to share pastors and church buildings. However, this alliance introduced theological tensions:
- New School: Centered in New York, Ohio, and New England, this wing embraced the revivalist methods of Charles Finney, interdenominational missionary and moral reform societies, and New Haven theology, which modified Calvinist doctrines of original sin. They also increasingly opposed chattel slavery.
- Old School: Centered in Pennsylvania, New Jersey, and the South, this faction championed strict confessional Calvinism, direct denominational control over mission boards and seminaries, and the theological scholarship of Charles Hodge at Princeton Theological Seminary.
In 1837, the Old School majority abrogated the Plan of Union and expelled four New School synods, splitting the denomination into rival Old School and New School General Assemblies. When the Civil War erupted in 1861, both branches fractured sectionally. Southern Old School presbyteries broke away to form the Presbyterian Church in the Confederate States (later known as the Presbyterian Church in the United States, or PCUS), leaving American Presbyterianism divided into northern and southern camps for more than a century.
The Fundamentalist-Modernist controversy and twentieth-century realignments
Between 1890 and 1930, the northern Presbyterian Church became the primary battleground of the Fundamentalist-Modernist controversy. As higher-critical German scholarship and Darwinian evolutionary theory swept through universities and seminaries, theological modernists sought to adapt Christian doctrine to contemporary culture.
In response, the 1910 General Assembly formulated five doctrinal essentials: the inerrancy of Scripture, the virgin birth of Christ, substitutionary atonement, the bodily resurrection, and the historical reality of miracles. In 1922, progressive Baptist preacher Harry Emerson Fosdick delivered a controversial sermon from the pulpit of First Presbyterian Church in New York City titled Shall the Fundamentalists Win?, challenging orthodox doctrines as outmoded. In 1924, more than 1,200 northern Presbyterian ministers signed the Auburn Affirmation, arguing that the Five Fundamentals were merely non-binding theories.
The foremost defender of orthodoxy was J. Gresham Machen, professor of New Testament at Princeton Seminary and author of the 1923 classic Christianity and Liberalism. When Princeton Seminary was reorganized in 1929 to give theological moderates control, Machen and orthodox faculty members resigned to found Westminster Theological Seminary in Philadelphia. After establishing an independent board for foreign missions in 1933, Machen was tried and suspended from the ministry. In June 1936, Machen and his supporters formed the Orthodox Presbyterian Church (OPC).
In the southern PCUS, traditionalists grew increasingly troubled by theological liberalism, the ordination of women, and impending merger with the northern church. In December 1973, delegates from 260 southern congregations gathered at Briarwood Presbyterian Church in Birmingham, Alabama, to establish the conservative, confessional Presbyterian Church in America (PCA).
In June 1983, northern and southern mainline bodies finally resolved their Civil War division, merging in Atlanta to create the Presbyterian Church (USA), or PCUSA, which stands today as the largest mainline Presbyterian denomination. However, subsequent disagreements over biblical authority and ordination led conservative congregations to leave the PCUSA to form the Evangelical Presbyterian Church (EPC) in 1981 and the Evangelical Covenant Order of Presbyterians (ECO) in 2012.

Visiting a Presbyterian church today
Presbyterian worship reflects the historic Calvinist principle of the regulative principle of worship, emphasizing reverent prayers, scripture reading, congregational psalmody and hymnody, pastoral expository preaching, and the celebration of the Lord's Supper and infant baptism. The sanctuary layout highlights the authority of the Word, typically featuring a central pulpit elevated above the communion table and baptismal font.
