American Protestants in the early nineteenth century faced intellectual and social challenge which made conspicuous the weakness of their own divided condition. The American Revolution—which was part of a larger upheaval in the Atlantic Community—had spread Enlightenment ideas, with their aggressive attack on orthodoxy. Quite typical was the lament of a convention of Massachusetts Congregational ministers in 1799 over “the present decay of Christian morals and piety, and the awful prevalence of speculative and practical infidelity.” Well before the middle eighteen-thirties the tide of deism had ebbed, but some, like the editors of the new Christian Review, were still building sea walls against it.
