Hart’s Legal Positivism, Hans Kelsen’s Pure Theory of Law, John Finnis’ Natural Law Theory, and Lon Fuller’s Natural Law Theory. The researcher explores consistencies of the legal theories with the biblical perspective of law, as well as inconsistencies of the legal theories with the biblical perspective of law. The researcher also comments on the application of the legal theories to the analysis of current legal issues.
