Bonhoefferolatry: an inordinate obsession and/or adoration of Dietrich Bonhoeffer, wherein his writings displace scripture as the new Word of God and the man is venerated as the first and only pontiff of the Protestant faith.
Bonhoefferolaters can be spotted easily. If they are not reading "The Cost of Discipleship" this very moment, you should be able to locate any one of them solemnly talking about "costly grace" or whipping out flashy dialectical phrases like "the Lord who meets us in judgment and grace".
In fact, the second question of the Westminster catechism is already being re-worked to say:
"What rule hath God given to direct us how we may glorfy and enjoy him?
Answer: The word of Dietrich Bonhoeffer, which is contained in Ethics, Life Together but chiefly in The Cost of Discipleship."
