Overview
The Cost of Discipleship is a 1937 book by German theologian Dietrich Bonhoeffer, considered to be a classic of Christian thought. It is centered on an exposition of the Sermon on the Mount, in which Bonhoeffer spells out what he believes it means to follow Christ. The book was first published in 1937, when the rise of the Nazi regime was underway in Germany. It was against this background that Bonhoeffer's theology of costly discipleship developed, which ultimately led to his death.
Summary
One of the most quoted parts of the book deals with the distinction which Bonhoeffer makes between "cheap" and "costly" grace. According to Bonhoeffer,
Cheap grace, Bonhoeffer says, is to hear the gospel preached as follows: "Of course you have sinned, but now everything is forgiven, so you can stay as you are and enjoy the consolations of forgiveness." The main defect of such a proclamation is that it contains no demand for discipleship. In contrast to costly grace,
Bonhoeffer argues that as Christianity spread, the Church became more "secularised", accommodating the demands of obedience to Jesus to the requirements of society. In this way, "the world was Christianised, and grace became its common property." But the hazard of this was that the gospel was cheapened, and obedience to the living Christ was gradually lost beneath formula and ritual, so that in the end, grace could literally be sold for monetary gain.
