Evangelicals like Russell Moore and Beth Moore are down on Christian nationalism, and a new book smears John Piper, Wayne Grudem, Francis Schaeffer, and Franklin Graham with the label. And the book is endorsed by Christianity Today and Tim Keller. What is "Christian Nationalism" and why the smear? Why is the social justice agenda pressing so hard against biblical law and Christian ethics? Has the salt lost all of its saltiness? Shall we just step aside and make way for Marxist ethics to take over everywhere in every country in the world now?
