For years, Russell Moore was one of the top officials in the Southern Baptist Convention. But after he criticized Donald Trump, Moore found himself ostracized from many other Evangelical leaders who embraced Trump and Trumpism.Moore eventually resigned from his post, and found himself on the outside of a denomination that had, up until that point, defined his life.Today, Moore argues that Christianity is in crisis in America, and he explores a way forward for the faith he loves in his book, "Losing Our Religion: An Altar Call For Evangelical America."
