Pope Pius XII reigned between 1939 and 1958, a period of catastrophic events. But history seems mainly concerned about his behaviour around the Holocaust. Pius has been accused of being a German sympathizer or at best failing to do his moral duty to help save the Jews of Europe by keeping silent. For others he was a saint who used his skill as a diplomat to save thousands of Jews from Nazi terror. But this week in Jerusalem, Yad Vashem, the world’s foremost Holocaust museum, softened its criticism of the wartime pope, allowing that despite faults he did help save Jewish lives.
