Reading about the CDF I invariably hear two things in my mind's ear: Mel Brooks'  "The Inquisition Yah Yah Yah" song and Monty Python's "Nobody expects the Spanish Inquisition!" routine.  I also think of St. Teresa of Avila who was brought before the Inquisition like five times.  There were others treated badly, including being excommunicated, who later became saints.
