From Mark Noll's The Civil War as Theological Crisis:
American national culture had been built in substantial part by voluntary and democratic appropriation of Scripture. Yet if by following such an approach to the Bible there resulted an unbridgeable chasm of opinion about what Scripture actually taught, there were no resources within democratic or voluntary procedures to resolve the public division of opinion that was created by voluntary and democratic interpretation of the Bible. The Book that made the nation was destroying the nation; the nation that had taken to the Book was rescued not by the Book but by the force of arms.
