Christian Reconstructionism is a fundamentalistReformed theonomic movement that developed under the ideas of Rousas Rushdoony, Greg Bahnsen and Gary North; it has had an important influence on the Christian Right in the United States. In keeping with the cultural mandate, Reconstructionists advocate theonomy and the restoration of certain biblical laws said to have continuing applicability. The movement declined in the 1990s and was declared dead in a 2008 Church History journal article, although Christian Reconstructionist organizations such as the Chalcedon Foundation and American Vision are active today. Christian Reconstructionists are usually postmillennialists and followers of the presuppositional apologetics of Cornelius Van Til.
A Christian denomination that advocates the view of Christian Reconstructionism is the Reformed Presbyterian Church in the United States. Most Reformed Christians, however, disavow Christian Reconstructionism and hold to classical covenant theology, the traditional Reformed view of the relationship between the Old Covenant and Christianity.
Christian Reconstructionists advocate a theonomic government and libertarian economic principles. They maintain a distinction of spheres of authority between family, church, and state. For example, the enforcement of moral sanctions under theonomy is carried out by the family and church government, and sanctions for moral offenses are outside the authority of civil government (which is limited to criminal matters, courts and national defense). However, some believe these distinctions become blurred, as the application of theonomy implies an increase in the authority of the civil government. Reconstructionists argue, though, that under theonomy, the authority of the state is severely limited to a point where only the judicial branch exists (e.g., a homosexual does not fear of a police force breaking in their house at night, since, under theonomy, there is no executive branch and therefore no police). Reconstructionists also say that the theocratic government is not an oligarchy or monarchy of man communicating with God, but rather, a national recognition of existing laws. Prominent advocates of Christian Reconstructionism have written that according to their understanding, God's law approves of the death penalty not only for murder, but also for propagators of all forms of idolatry, active homosexuals,adulterers, practitioners of witchcraft, and blasphemers, and perhaps even recalcitrant youths (see the List of capital crimes in the Bible). American Vision's Joel McDurmon responded to these criticisms by denying that Reconstructionists have promoted coercive means.
