This issue of Forum marks the first in a two-part series on Christian Nationalism. Four distinguished authors set the table for a robust discussion. They trace the movement's roots back into antiquity and help the reader sight the troubling future at which Christian Nationalists aim. A slim volume with four great essays, this material is a perfect primer for study groups and a doorway into a deep and troubling issue. Bernard Brandon Scott, Jeffrey W. Robbins, Arthur J. Dewey, and John D. Caputo display this movement's roots in the Christian tradition, the distortion thereof that it represents, and offer a clear-eyed view about the threat posed to liberal democracy.
