"Moreover, to kings, princes, rulers, and magistrates, we affirm that chiefly and most principally the conservation and purgation of the religion appertains; so that not only they are appointed for civil policy, but also for maintenance of the true religion, and for suppressing of idolatry and superstition whatsoever: as in David, Jehoshaphat, Hezekiah, Josiah, and others, highly commended for their zeal in that case, may be espied." - The Scottish Confession of Faith (written by John Knox and others), Chapter 24, 1560, on the Puritan Hard Drive
"The nations are bound to recognize the Bible as the supreme law of the land; as the standard of civil legislation. God's law as recorded in the Bible, reaches all the possible relations of humanity; extends to every duty that can be performed, and fastens its claims on associated bodies of men, as well as upon individual persons. Were this not true, we should have this monstrous anomaly in Jehovah's government, that while men, as individuals, are bound by the laws recorded in the Bible, in their congregated capacities, they may set these laws at defiance, and even contemn as citizens, what as Christians they are bound to honor and obey. ... The nations are bound to evince their subjection to the Son of God, by filling all their official stations with upright, godly and able men. ... In all their political institutions the nations are bound to subserve the interests of the church of God, and promote, truth and godliness. ... In all their civil, criminal, and international concerns, the kingdoms should have a supreme regard to the glory of God." - The Subjection of Kings and Nations to Messiah (1820) by James R. Willson (emphases added)
