Ying Huang offers a new reading of Bonhoeffer's conception of 'nonreligious Christianity', based on an extensive analysis of his concept of religion in the theologian's earliest writings up to 1935. The result of the interpretation shows that there is a better outline for Bonhoeffer's concept of religion, namely the twofold shift in meaning from 1) a sociological concept of religion to 2) an epistemological to 3) one that is to be understood as an antonym for the kingdom of God.
