In this book you’ll read about the American church’s sickening record of supporting racism. Many would prefer this history to remain locked away and hidden. But Martin Luther King Jr. gave an important rationale for shining a light on injustice, despite the pain it may provoke. “Like a boil that can never be cured so long as it is covered up but must be opened with all its ugliness to the natural medicines of air and light,” he wrote, “injustice must be exposed, with all the tension its exposure creates, to the light of human conscience and the air of national opinion before it can be cured.”
