Martin Luther was a German monk, theologian, university professor, priest, father of Protestantism, and church reformer. His ideas started the Protestant Reformation. Luther taught that the gift of getting saved is a free gift of God and received only through true faith in Jesus as redeemer from sin.
It is the "Great Chain of Being"--derived from the thinking of Plato and Aristotle-- that recognizes God as the ultimate authority in government and law, and of course over all humans and animals.
