Russell Moore, the author of Losing Our Religion, was a solid conservative Southern Baptist preacher and theologian; yet his insightful criticism of Donald Trump defines his story. Most recently, Moore was on staff at a nondenominational church in Nashville and served as Editor-in-Chief for Christianity Today. Moore argues that American evangelical Christianity has lost its way, and church congregations are torn apart by Donald Trump.
Moore sees evangelicals walking away from evangelical churches not because they do not believe what the church teaches, but because they believe the church itself does not believe what it is teaching. Thus, Christianity has declined into political tribalism and culture warfare. He is particularly critical of Christian Nationalism, saying that it is to Christianity what the Nation of Islam is to the Muslim faith. He says evangelicals have to turn away from tribalism and embrace truth, and that truth is Jesus Christ. That is why the book is An Alter Call for Evangelical America.
