The Reformed Church in America is a historic Protestant denomination tracing its origins to seventeenth-century Dutch settlers in New Amsterdam. Grounded in continental Calvinism and the Three Forms of Unity rather than Scottish Presbyterianism, it shares close theological roots with the Christian Reformed Church while displaying a distinctive heritage of colonial ministry and civic engagement.
Reformed Church in America: Origins in New Netherland and Collegiate Church
The story of continental Reformed Christianity in North America begins in 1628 with the arrival of Domine Jonas Michaëlius in the Dutch West India Company settlement of New Amsterdam on Manhattan Island. Michaëlius gathered fifty communicants to celebrate the Lord's Supper, establishing the Collegiate Reformed Protestant Dutch Church. Today, this body survives as the Collegiate Church of New York, recognized as the oldest continuous Protestant congregation with an unbroken ministry in North America.
Throughout the colonial period, the Dutch Reformed Church operated under the ecclesiastical oversight of the Classis of Amsterdam. Pastors were educated in the Netherlands and sent across the Atlantic to minister to Dutch-speaking farming communities throughout the Hudson River Valley, northern New Jersey, and western Long Island. Even after the English seized New Netherland in 1664 and renamed it New York, the Dutch churches secured royal charters preserving their language, property, and confessional liberties.
By the mid-eighteenth century, tensions emerged between the "Coetus" party, which favored American self-governance and domestic ministerial training, and the conservative "Conferentie" party, which insisted on continued dependence upon the Classis of Amsterdam. In 1766, Coetus leaders secured a royal charter to establish Queen's College (now Rutgers University) in New Brunswick, New Jersey, followed in 1784 by the founding of New Brunswick Theological Seminary, the oldest Protestant seminary in North America. In 1792, the denomination adopted an independent American constitution, taking the name Reformed Protestant Dutch Church in North America, shortened in 1867 to the Reformed Church in America (RCA).
The Three Forms of Unity: Continental Reformed confessions
While English-speaking Presbyterians adopted the Westminster Standards, continental Reformed churches adhere to the Three Forms of Unity as their historic doctrinal foundation. Originating in sixteenth- and seventeenth-century European struggles for religious reformation, these three documents define classic Reformed orthodoxy:
- The Belgic Confession (1561): Composed by Guido de Brès in the southern Low Countries during intense Spanish Catholic persecution. Written to demonstrate to King Philip II that Reformed Christians were law-abiding believers who upheld apostolic Christianity rather than radical revolutionaries, the confession provides a thorough, systematic statement of Reformed dogmatics.
- The Heidelberg Catechism (1563): Commissioned by Elector Frederick III of the Palatinate and written primarily by theologians Zacharias Ursinus and Caspar Olevianus. Renowned for its warm, pastoral tone, the catechism is structured around three central themes: Guilt (human misery under sin), Grace (deliverance through Jesus Christ), and Gratitude (thankful Christian living in obedience to God's commandments). Its opening question famously asks, "What is your only comfort in life and in deat—
- The Canons of Dort (1618–1619): Formulated at an international synod convened in Dordrecht, Netherlands, to answer the theological challenges raised by the followers of Jacobus Arminius. The Canons defined five doctrinal points regarding divine election, human depravity, and sovereign grace that subsequently formed the basis for modern Calvinist soteriology.
Together, these standards confess the absolute sovereignty of God, salvation solely by divine grace through faith in Christ, and the authority of Holy Scripture. Studying the central teachings of John Calvin reveals how these European confessions preserved a unified theological witness across national boundaries.
The 1857 Secession: Emergence of the Christian Reformed Church
During the 1840s, economic hardship and state interference in the Netherlands prompted a fresh wave of devout Dutch emigration. Led by ministers Albertus van Raalte and Hendrik Scholte, these settlers founded immigrant colonies in western Michigan and central Iowa. Seeking theological fellowship, Van Raalte negotiated a union in 1850 between the Michigan immigrant churches and the established Reformed Church in America based in New York.
However, the alliance quickly proved contentious. Many immigrant farmers believed the older eastern RCA had become culturally Americanized and doctrinally compromised. Critics objected to the RCA's tolerance of fraternal lodge membership (such as Freemasonry), its use of non-biblical hymns in corporate worship alongside traditional metrical Psalms, and its perceived neglect of rigorous catechetical instruction for children.
In April 1857, four Michigan congregations led by elder Gysbert Haan seceded from the RCA to form what eventually became the Christian Reformed Church in North America (CRCNA). Establishing its intellectual and institutional center in Grand Rapids, Michigan, the CRC founded Calvin College (now Calvin University) and Calvin Theological Seminary in 1876. While the RCA leaned toward broader ecumenical involvement, the CRC embraced the neo-Calvinist philosophy of Dutch theologian and prime minister Abraham Kuyper, asserting that Jesus Christ claims sovereignty over every square inch of human culture, education, politics, and science.
Twentieth-century developments and recent denominational realignments
Throughout the twentieth century, both denominations expanded across North America while managing internal debates regarding biblical interpretation, women's ordination, and cultural assimilation. According to official denominational records, the CRCNA comprised approximately 190,000 members across more than 1,000 congregations in the United States and Canada in 2023. The CRC ordained women as deacons in 1984 and granted local synodical permission for women to serve as elders and ministers in 1995, though regional classes retain discretion regarding local implementation.
The Reformed Church in America maintained a prominent public presence through suburban church expansion and television broadcasts, including Robert Schuller's Hour of Power from the Crystal Cathedral in Garden Grove, California. The RCA approved the ordination of women to all church offices in 1979. However, theological divisions over marriage definitions and human sexuality accelerated during the 2010s. Following the RCA General Synod's decisions in 2021 allowing graceful separation, more than 150 conservative congregations withdrew to form the Alliance of Reformed Churches (ARC) or join the Presbyterian Church in America.
By the end of 2023, the RCA's official statistical summary reported 86,275 total members across 603 congregations. Despite these contractions, both the RCA and CRC maintain active international relief agencies, world missions, and university campuses that continue to influence American Christianity.
German Reformed heritage: Mercersburg theology and the United Church of Christ
The continental Reformed tradition in America also includes a major German component. During the eighteenth century, thousands of German Reformed refugees from the Palatinate emigrated to Pennsylvania, Maryland, and Virginia. Organized by pioneer pastors John Philip Boehm and Michael Schlatter, these congregations formed the Synod of the High German Reformed Church in 1793.
During the nineteenth century, professors John Williamson Nevin and Philip Schaff at Mercersburg Seminary in Pennsylvania formulated "Mercersburg Theology." Countering emotional revivalism and individualism on the American frontier, Mercersburg emphasized high-church liturgical worship, the central importance of the church as Christ's ongoing historical body, and the real spiritual presence of Christ in the Lord's Supper, anticipating modern ecumenical liturgical renewals.
In 1934, the German Reformed Church merged with the German Evangelical Synod of North America (a union of Lutheran and Reformed immigrants) to create the Evangelical and Reformed Church (E&R). In 1957, the E&R Church united with the Congregational Christian Churches to establish the United Church of Christ (UCC), bringing a substantial portion of German Reformed heritage into mainline Protestantism. A small conservative minority declined this union, continuing today as the Reformed Church in the United States (RCUS), an active confessional body adhering strictly to the Heidelberg Catechism.
Comparing Dutch Reformed and Scottish Presbyterian traditions
Worshipers examining continental Reformed bodies alongside Scottish Presbyterian traditions will discover identical Calvinist soteriology expressed through slight differences in church terminology and history. Where Presbyterians speak of sessions, presbyteries, and General Assemblies, Reformed churches speak of consistories, classes, and regional synods. Both traditions emphasize representative church government, elder leadership, and infant baptism within covenant theology.
When comparing the the historic Westminster Confession of Faith with the Three Forms of Unity, both systems affirm the core theological doctrines that Presbyterians believe regarding human depravity, divine election, and saving grace. When evaluating different Presbyterian denominations alongside Dutch Reformed bodies, believers will find substantial unity across theological lines. Furthermore, reviewing the geographic presence of Presbyterian churches by state illustrates how Dutch Reformed communities in western Michigan, central Iowa, and northern New Jersey continue to complement Scots-Irish Presbyterian hubs in Pennsylvania and the South.
Those seeking to worship in local Presbyterian and Reformed congregations will find reverent, scripture-saturated gatherings. Reading a comprehensive guide to Reformed worship services or exploring the broader history of the Presbyterian Church offers meaningful guidance before attending Sunday morning services in these historic communions.
