A new book by Presbyterian minister and scholar Craig Munro Wilson examines a long-overlooked 1820 debate that he argues was a defining moment for American Christianity. Published as the United States approaches its 250th anniversary, 'Baptize America' delves into the two-day confrontation between Ulster-Scots ministers Alexander Campbell and Rev. John Walker in Mount Pleasant, Ohio, on June 19, 1820.
Wilson, a doctoral scholar from the University of Glasgow, spent over a decade reconstructing the debate in forensic detail. The book is the first in-depth analysis since the debate's original publication in 1824. According to Wilson, the dispute over infant baptism was not a mere frontier curiosity but the opening engagement in a theological war that helped determine the character of American Christianity.
The debate pitted Campbell, who argued against infant baptism using a two-covenant framework, against Walker, a Seceder Presbyterian who defended covenantal infant baptism. Neither conceded. Wilson places the debate within three contexts: Campbell's early ministry, the ecclesiastical tensions of frontier Presbyterianism and Baptist life, and the broader societal conditions of the American frontier—a world shaped by Ulster-Scottish immigration and evangelism.
A key contention of the book is a theological shift that has gone largely unremarked. 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 through subsequent debates, a journey Wilson argues Evangelical Christianity, particularly within the Reformed tradition, has yet to complete.
The title 'Baptize America' is drawn from a contemporary revival movement initiated in 2023 by Pastor Mark Francey, which aimed to baptize Californians en masse on Pentecost Sunday before expanding nationally. Wilson connects that movement to Campbell's mature conviction that mass baptism was tied to the nation's millennial future, showing that what seems modern is actually a very old idea.
Wilson, a paedobaptist Presbyterian minister from Co. Donegal, notes that he studied the man he was trained to disagree with and ended up closer to his conclusions than his own tradition would expect. His book argues that the frontier Campbell and Walker debated on is long gone, but the questions they argued over remain unresolved. As America marks its 250th year, Wilson uses the moment deliberately, not decoratively, to highlight that the theological struggles of the frontier continue to resonate.
