There is a movement today identified as Reconstructionism or Dominion Theology that has its roots in postmillennialism. It advocates establishing a theocratic kingdom in America based on the judicial laws of Moses. In fact, by its reasoning, the Christian is under a divine mandate to accomplish this end. It has been popularized in recent years by Rousas J. Rushdoony in The Institutes of Biblical Law and Greg Bahnsen in Theonomy in Christian Ethics. Out of this has come the Chalcedon school which is a foundation that identifies itself as an independent Christian educational organization.
