Sounds interesting - just checked it out on amazon. What kind of writing is it? Historical fictional narrative? History-book style?
The book traces the development of the religious beliefs and behaviors that led to the Holocaust and the erecting of a large cross at Auschwitz.
The ideas of important secular-religious figures and institutions are presented - people such as Jesus, Paul, Constantine, Ambrose, Augustine, Anselm, Abelard and Heloise, Thomas Aquinas, Voltaire, the Popes, the Kings, Luther, Alfred Dreyfus and LaCroix, and so on. Some of these represent missed opportunities to do better. There is some discussion of Jewish religious thought and figures.
The book does have a narrative aspect as well. Carrol presents the history as an illumination of his own personal religious journey.
It is a very good read.
That does sound interesting. Maybe I'll ask for it for Christmas.
