What is Reconstructionism?
Reconstructionism is a theology that arose out of conservative Presbyterianism (Reformed and Orthodox), which proposes that contemporary application of the laws of Old Testament Israel, or "Biblical Law," is the basis for reconstructing society toward the Kingdom of God on earth.
Reconstructionism argues that the Bible is to be the governing text for all areas of life--such as government, education, law, and the arts, not merely "social" or "moral" issues like pornography, homosexuality, and abortion. Reconstructionists have formulated a "Biblical world view" and "Biblical principles" by which to examine contemporary matters. Reconstructionist theologian David Chilton succinctly describes this view: "The Christian goal for the world is the universal development of Biblical theocratic republics, in which every area of life is redeemed and placed under the Lordship of Jesus Christ and the rule of God's law."
Christian Historical Revisionism
Part of the Reconstructionist world view is a revisionist view of history called "Christian history," which holds that history is predestined from "creation" until the inevitable arrival of the Kingdom of God. Christian history is written by means of retroactively discerning "God's providence."
Most Reconstructionists, for example, argue that the United States is a "Christian Nation" and that they are the champions and heirs of the "original intentions of the Founding Fathers." This dual justification for their views, one religious, the other somehow constitutional, is the result of a form of historical revisionism that Rushdoony frankly calls "Christian revisionism." http://www.publiceye.org/magazine/v08n1/chrisre1.html
