Chapter 2 explicates the theology behind southern evangelicals’ resistance to civil rights. It explains why conservative white Christians opposed civil rights reforms, arguing that a significant percentage of these Christians constructed a theology from both the natural world and biblical texts in which God was viewed as the author of segregation, and one who desired that racial separatism be maintained. Referencing letters, sermons, pamphlets, and books, this chapter documents how segregationist theology was crafted, defended, and deployed throughout the 1950s and 1960s in the South. It also demonstrates how such a theology supported a segregationist Christianity that became common in southern white churches, proving influential in shaping the social and political responses white southerners had to the civil rights movement.
