The Bondage of the Will

On the Bondage of the Will (Latin: 'De Servo Arbitrio', literally, "On Un-free Will", or "Concerning Bound Choice"), by Martin Luther, was published in December 1525. It was his reply to Erasmus's De libero arbitrio diatribe sive collatio or On Free Will, which had appeared in September 1524 as Erasmus's first public attack on Luther, after being wary about the methods of the reformer for many years. At issue was whether human beings, after the Fall of Man, are free to choose good or evil. The debate between Luther and Erasmus is one of the earliest of the Reformation over the issue of free will and predestination. Luther maintained that sin incapacitates human beings from working out their own salvation, that they are completely unable to bring themselves to God. In this treatise, he begins by examining Erasmus's argument. He then discusses the power and complete sovereignty of God and lays out his own argument. His conclusions are that unredeemed human beings are dominated by Satan: Satan as the prince of this world never lets go of what he considers his own unless he is overpowered by a stronger power, i.e. God. When God redeems a person, he redeems the entire person, including the will, which then is liberated to serve God.
