Prominent theopolitical thinkers of recent decades, including Yoder, Hauerwas and Cavanaugh, have called attention to key ways in which the church loses its identity as a distinctive polis. Constantinian habits of thinking, liberalism’s hostility to traditions (“no story but the story I choose for myself”), and the modern order’s relegation of “religion” to a “private,” over against a “public” sphere, have each been examined in association with the church’s inability to be the church. But what role does the phenomenon of nationalism play in the church’s going astray? This question, coupled with another—‘In what ways is the church itself responsible for going astray from its true identity?’—is at the heart of Braden Anderson’s important study. He strives to display how the formal study of nationalism both builds on and transforms theopolitical thought up to this day, especially by calling attention to internal (including, importantly, scriptural) sources of the distortion of the church’s identity.
