Church of Scotland Act 1921

VI This Church acknowledges the divine appointment and authority of the civil magistrate within his own sphere, and maintains its historic testimony to the duty of the nation acting in its corporate capacity to render homage to God, to acknowledge the Lord Jesus Christ to be King over the nations, to obey His laws, to reverence His ordinances, to honour His Church, and to promote in all appropriate ways the Kingdom of God. The Church and the State owe mutual duties to each other, and acting within their respective spheres may signally promote each other's welfare. The Church and the State have the right to determine each for itself all questions concerning the extent and the continuance of their mutual relations in the discharge of these duties and the obligations arising therefrom.
