The good news: After years of agitation among prelates, historians and Jewish leaders, on March 2 the Vatican will fully open its covert archives that cover Pope Pius XII’s performance during the Nazi era.

The bad news for journalists: It will take months, even years, for expert researchers to draw coherent conclusions from the estimated 16 million pages of documents. Neverthelessl, retrospectives on the Pius debate since the 1960s will be timely just now, drawing upon the massive material in newsroom morgues and online.

The issues surrounding this pontiff — a long-pending and controversial candidate for sainthood — are huge for Jewish relations. Beginning in 1920, Pius was the Vatican’s envoy to Germany, and during his years as secretary of state its top strategist on Nazism. Then his 1939 election as pope coincided with war and the Holocaust.

The big historic question: Did he say and do enough as Hitler’s regime oppressed Jews and eventually slaughtered them by the millions?

The Vatican completed a partial release of historical texts on Pius in 1981 but the new, complete batch is expected to be more enlightening. The Holy See is offering assurances that scholars are welcome to apply for access to the collection regardless of religious views or ideologies. What historians are in line, and what journalists will be on the list?
