Russell Moore resigned from his position in the Southern Baptist Convention after finding himself at odds with other top evangelical leaders – for criticizing Donald Trump, condemning a sexual abuse scandal in the church, and calling out white nationalism within the institution. In his new book, Losing Our Religion, the Christianity Today editor-in-chief examines how the evangelical faith became inundated with politics and culture wars. He tells NPR's Scott Detrow about how despite today's polarization in Christianity, his faith has become stronger – and he sees a path to renewal.
