"The explosive untold story of the most dangerous churchman in modern history -- drawn from secret archives by an award-winning Roman Catholic journalist Eugenio Pacelli, Pius XII -- a man with unprecedented power for... evil... was pope from 1939 to 1958. Today, still shadowed by his failure to condemn Hitler's Final Solution, he is at the same time nearing canonization. Backed by new research and exclusive access to a wealth of Vatican and Jesuit archives, John Cornwell tells for the first time, in depth, the truth about Pacelli's long career as a Vatican diplomat and the accord between Pacelli and Hitler that helped sweep the Nazis to unhindered power. Hitler's Pope shows how Pacelli's entire life and career led to this, from a brilliant young Vatican lawyer drafting new papal power for the twentieth century to his 1933 Concordat with Hitler that muzzled protest by Germany's Catholic community, the most powerful in the world. Cornwell's explosive conclusion is that without Pacelli's contribution, Hitler might never have come to power or been able to press forward with the Holocaust... Hitler's Pope conclusively documents Pius XII's anti-Semitism, narcissism, and calamitous mix of political and spiritual ambition -- and it shows how many of Pacelli's policies are reasserting themselves today under the reign of John Paul II" (Thomas Merton).
