The ideas in Lex Rex predate modern concepts of nationalism and politics. They are older than the United States Constitution, as well as the American Revolution - where many modern ideas of liberty originated. Lex Rex is even older than the Enlightenment that receives so much credit for concepts such as popular sovereignty, limited government, separation of powers, and individual liberty. Nevertheless, Samuel Rutherford's Lex Rex - written at a time that viewed kings as vessels of divine power - raised a Scriptural standard arguing for the dignity of the people and the accountability of earthly governments. Although some would seek to pigeonhole the book as merely a tract on civil resistance, Lex Rex contains a comprehensive examination of a Christian view of civil government. In doing so, Lex Rex actually formulates a blueprint for freedom applicable for any time and any place. Rutherford hoped to demonstrate the need for government based on law instead of the arbitrary decisions of fallible humanity. Throughout this process, the Bible is the final authority and basis for law. This Scriptural base was a primary reason for both the great support and opposition that met Lex Rex.
