Justice: Law is King - Lex Rex

All, whether king, president, rich, poor, famous, or commoner are accountable to the law.

When Jesus said “Render unto Caesar the things that are Caesar’s, and to God the things that are God’s,” He was making clear that the civil government has limitations. The State is not the “be all and end all.” It cannot declare just anything to be its own. They cannot make up law as they go, nor change the immutable laws of God.

Lex, Rex, or The Law and the Prince; a Dispute for the Just Prerogative of King and People [written by Samuel Rutherford], published in 1644, is probably the greatest work on the foundation, nature and constitutional limits of Government, the Civil Magistrate, and the separate but mutual relationship of Church and State ever written...
