Today, a new crop of mainstream evangelicals has taken up the cause of the New Left, whether they know it or not. As pro-life evangelicals rush to support movements like #BlackLivesMatter and #MeToo, it is important to realize they are walking in footprints already laid down. Their mission may be more successful, but it is not new. To understand where the evangelical social justice movement is heading, it is vital to understand the origins of the movement. Host Matthew Nowlin welcomes Jon Harris author of "Social Justice Goes To Church: The New Left in Modern American Evangelicalism," to discuss these current trends.
