In this meticulously researched, unflinching, and reasoned study, National Book Award finalist David I. Kertzer presents shocking revelations about the role played by the Vatican in the development of modern anti-Semitism. Working in long-sealed Vatican archives, Kertzer unearths startling evidence to undermine the Church's argument that it played no direct role in the spread of modern anti-Semitism. In doing so, he challenges the Vatican's recent official statement on the subject, We Remember. Kertzer tells an unsettling story that has stirred up controversy around the world and sheds a much-needed light on the past.
