The country had a problem because of its most trusted religious authority, the Bible, was sounding an uncertain note. The evangelical Protestant churches had a problem because the mere fact of trusting implicitly in the Bible was not solving disagreements about what the Bible taught concerning slavery. The country and the churches were both in trouble because the remedy that finally solved the question of how to interpret the Bible was recourse to arms. The supreme crisis over the Bible was that there existed no apparent biblical resolution to the crisis. As I have written elsewhere, it was left to those consummate theologians, the Reverend Doctors Ulysses S. Grant and William Tecumseh Sherman to decide what in fact the Bible actually meant.
pg 159 -160:
The theological crisis of the Civil War was that while voluntary reliance on the Bible had contributed greatly to the creation of American national culture, that same voluntary reliance on Scripture led only to deadlock over what should be done about slavery. After the shooting stopped, two great problems in practical theology confronted the United States. One was the enduring reality of racism, which displayed its continuing force almost as virulently through the mob and the rope as it had in the chain and the lash.
The other was the expansion of consumer captialism, in which unprecedented opportunities to create wealth were matched by large-scale alienation and considerable poverty in both urban and rural America... But the Civil War was won and slavery was abolished not by theological orthodoxy but my military might and a hitherto unimaginable degree of industrial mobilization.
Although the war freed the slaves and gave African Americans a constitutional claim to citizenship, it did not provide the moral energy required for rooting equal rights in the subsoil of American society or for planting equal opportunity throughout the land. Although the war showed what could be accomplished through massive industrial mobilization , it did not offer clear moral guidance as to how that mobilization could be put to use for the good of all citizens.
Pg 162:
From the historical record it is clear that the American Civil War generated a first-order theological crisis over how to interpret the Bible, how to understand the work of God in the world, and how to exercise the authority of theology in a democratic society.
