Craig Munro Wilson, a Presbyterian minister from Ulster and doctoral scholar, has published a new book titled Baptize America that reexamines a pivotal but overlooked theological debate from 1820. The book argues that the two-day confrontation between Alexander Campbell and Rev. John Walker in Mount Pleasant, Ohio, was not merely a frontier curiosity but a foundational moment in American Christianity.
The debate, which drew approximately two thousand people to a Quaker meeting house, centered on the nature of baptism. Campbell, arguing against infant baptism from a two-covenant perspective, faced Walker, a Seceder Presbyterian who defended covenantal infant baptism. Neither conceded, and the published record of the exchange had remained largely unexamined for two centuries.
Wilson, who holds a doctorate from the University of Glasgow—Campbell's alma mater—places the debate within three contexts: Campbell's early ministry, the tensions of frontier Presbyterianism and Baptist life, and the broader societal conditions of the American frontier. The frontier, Wilson contends, was a contested space where faith, covenant, and national identity were being negotiated amid waves of Ulster-Scottish immigration.
A key finding in the book is a theological shift that has gone unnoticed. In 1820, both Campbell and Walker viewed baptism as a sign rather than a sacrament conferring grace. Wilson traces how Campbell moved toward full sacramentalism by 1843, a journey he argues Evangelical Christianity, particularly within the Reformed tradition, has yet to complete.
The book's title is drawn from a contemporary revival movement initiated in 2023 by Pastor Mark Francey, which aimed to baptize Californians en masse on Pentecost Sunday. Wilson connects that movement to Campbell's conviction that mass baptism of the American people was linked to the nation's millennial future. As the United States enters its 250th year, Wilson uses this milestone to highlight that while the frontier is gone, the questions debated by Campbell and Walker remain relevant.
Baptize America is the first work since the debate's original publication in 1824 to examine it in depth. Wilson, a paedobaptist Presbyterian minister, spent a decade studying Campbell, a man he was trained to disagree with, and found himself closer to Campbell's conclusions than his own tradition would expect.
