John R. McKivigan employs both conventional and quantitative historical techniques to assess the positions adopted by various churches in the North during the growing conflict over slavery, and to analyze the stratagems adopted by American abolitionists during the 1840s and 1850s to persuade northern churches to condemn slavery and to endorse emancipation. Working for three decades to gain church support for their crusade, the abolitionists were the first to use many of the tactics of later generations of radicals and reformers who were also attempting to enlist conservative institutions in the struggle for social change. To correct what he regards to be significant misperceptions concerning church-oriented abolitionism, McKivigan concentrates on the effects of the abolitionists' frequent failures, the division of their movement, and the changes in their attitudes and tactics in dealing with the churches. By examining the pre-Civil War schisms in the Presbyterian, Baptist, and Methodist denominations, he shows why northern religious bodies refused to embrace abolitionism even after the defection of most southern members. He concludes that despite significant antislavery action by a few small denominations, most American churches resisted committing themselves to abolitionist principles and programs before the Civil War. In a period when attention is again being focused on the role of religious bodies in influencing efforts to solve America's social problems, this book is especially timely.
