While many Christians believe that biblical law is a guide to morality and public ethics, when interpreted in faith, Reconstructionism is unique in advocating that civil law should be derived from and limited by biblical law. For example, they support the recriminalization of acts of abortion and homosexuality, but also oppose confiscatory taxation, conscription, and most aspects of the welfare state. Protection of property and life needs grounding in biblical law, according to Reconstructionism, or the state set free from the restraint of God's law will take what it wishes at a whim. Accordingly, Reconstructionists advocate biblically derived measures of restitution, a definite limit upon the powers of taxation, and a gold standard or equivalent fixed unit for currency.
Christian Reconstructionists describe their view of public ethics by the term, "Theonomy" (the Law of God governs); while their critics tend to label them "Theocratic" (God governs). The notable differences are that "theocracy" is usually thought of as totalitarian and involving no distinction between church and state, while Reconstructionists claim that "theonomy" is broadly libertarian and maintains a distinction of sphere of authority between family, church, and state.[2] For example, enforcement of moral sanctions under theonomy is done by family and church government, and sanctions for moral offenses is outside the authority of civil government (which is limited to criminal matters, courts and national defense). However, in some areas the application of theonomy could increase the authority of the civil government; 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 idolatry[3][4][5], active homosexuals[6], adulterers, practitioners of witchcraft, and blasphemers[7], and perhaps even recalcitrant youths[8] (see the List of capital crimes in the Bible).
