Early Life and Formation

Philip Schaff was born in Switzerland in 1819 and educated in the German-speaking world at a time when historical study of Christianity was reshaping Protestant theology. As a young scholar he gravitated to the great lecture halls of German universities and came under the enduring influence of August Neander in Berlin, whose blend of piety and rigorous historical method left a decisive mark on Schaff's outlook. The emerging disciplines of church history and historical theology became his intellectual home, and his training prepared him to interpret the life of the church across centuries with sympathy for diverse confessional traditions. The breadth of his formation equipped him to mediate between European scholarship and the needs of a rapidly growing American Protestant culture.

Mercersburg: Theology, Teaching, and Controversy

In the early 1840s Schaff accepted a call to the theological seminary of the German Reformed Church in Mercersburg, Pennsylvania, to teach church history and related subjects. There he formed a close partnership with John Williamson Nevin, and together they shaped what came to be known as the Mercersburg Theology. Their work emphasized the organic development of Christian doctrine, the centrality of the incarnation, and a richer understanding of sacramental and liturgical life within Reformed Protestantism. Schaff's inaugural address, The Principle of Protestantism, argued that the Reformation should be seen as a positive, churchly renewal rather than a mere negation of medieval Catholicism. The address and subsequent publications provoked vigorous debate. Leading critics such as Charles Hodge at Princeton feared that the Mercersburg program endangered core Protestant convictions, while supporters saw in it a corrective to individualism and a bridge to the wider Christian tradition. Schaff faced formal charges of heresy within his denomination and was acquitted, an outcome that confirmed his standing but also underscored the unsettled state of American theology in the mid-nineteenth century.

Alongside the doctrinal debates, Schaff worked with Nevin on liturgical reform for the German Reformed Church. Their contributions to a churchly order of worship aimed to restore historical continuity without surrendering Reformation principles. This blend of historical sympathy and Protestant conviction defined his teaching and helped train a generation of pastors to think about the church not only as a collection of individuals but as a living communion across time.

Scholarship: Histories, Creeds, and the Fathers

Schaff's long-range scholarly project was to narrate the life of the Christian church from its apostolic beginnings to the modern age. His multivolume History of the Christian Church became a standard work in English, prized for its command of sources, clear organization, and even-handed treatment of competing traditions. He complemented narrative church history with documentary scholarship, producing The Creeds of Christendom, which assembled, translated, and annotated the major confessional statements of the churches. This work helped English-speaking readers grasp the inner logic of Catholic, Orthodox, and Protestant self-understandings and provided a ready reference for students and clergy.

Committed to making the classic sources of the faith accessible, Schaff supervised major English editions of the writings of the early church, working with collaborators such as Henry Wace and, in related volumes, Arthur Cleveland Coxe. He also served as editor for a comprehensive religious encyclopedia that adapted and expanded Johann Jakob Herzog's famed German reference work for an American audience. The resulting Schaff-Herzog Encyclopedia of Religious Knowledge introduced a wide readership to critical, yet sympathetic, treatments of biblical, theological, and historical topics and became a fixture in theological libraries.

Ecumenism and Public Leadership

Schaff's temperament and scholarship made him a natural leader in efforts to foster cooperation among Protestants and to promote understanding across confessional lines. He took a prominent role in the Evangelical Alliance, helping to organize its 1873 international conference in New York City, which gathered church leaders from Europe and North America for prayer, deliberation, and common witness. In that forum he drew on friendships with figures across the spectrum of American Protestantism and used his European connections to advance practical Christian unity without obscuring real differences.

He was equally active in the realm of the Bible's public use. Schaff served as secretary of the American committee for the revision of the English Bible, coordinating the work of American scholars such as Ezra Abbot and maintaining close relations with the British revisers, including Brooke Foss Westcott and F. J. A. Hort. The transatlantic collaboration that produced the revised English versions required diplomacy, organization, and scholarly judgment, qualities Schaff supplied in abundance. His efforts ensured that the American contributions were both heard by British counterparts and responsibly represented to American churches.

Union Theological Seminary and the Maturing of His Influence

After years at Mercersburg and the subsequent relocation of the German Reformed school, Schaff accepted a call to Union Theological Seminary in New York City, where he taught church history for the remainder of his career. At Union he stood alongside figures such as Henry Boynton Smith and Roswell D. Hitchcock in shaping a faculty known for combining evangelical earnestness with modern learning. He also interacted with younger colleagues, among them Charles A. Briggs, as the seminary navigated the rising currents of biblical criticism and historical study at the end of the nineteenth century. Schaff's classroom and public lectures trained pastors, missionaries, and scholars to appreciate the breadth of the Christian past and to bring historical insight to contemporary questions.

Schaff helped institutionalize the scholarly study of church history in the United States by helping to found the American Society of Church History and serving as its leader. Through that society, and through his vast network of correspondents, he connected American historical theology to the best work in Europe while encouraging a distinctly American contribution to the field.

Final Years and Legacy

In his later years Schaff continued to revise and expand his History of the Christian Church, bringing additional periods into view and refining earlier volumes in light of new research. He also supervised ongoing encyclopedic and patristic projects, ensuring coherent standards across multiple contributors. His family circle supported his work, and after his death in 1893 his son David Schley Schaff assisted in editing and completing projects that bore the Schaff name.

Philip Schaff's legacy rests on three pillars: a historically informed understanding of Protestantism that respected the wider catholic tradition; a tireless commitment to making primary sources and reliable reference works available in English; and a generous ecumenical spirit that built bridges among scholars and churches. The controversies he weathered with John Williamson Nevin, the criticisms leveled by Charles Hodge, the collegial labors with Henry Boynton Smith, Roswell D. Hitchcock, and Charles A. Briggs, and the transatlantic partnerships with Ezra Abbot, Westcott, Hort, Henry Wace, and Arthur Cleveland Coxe all testify to the breadth of his relationships and the scope of his ambitions. Rooted in Swiss origins and German training, and matured in American institutions, he left behind a model of scholarship in service to the church that continues to shape historical theology and ecumenical conversation.
