Or so says the U.S. Holocaust Memorial Museum in Washington, when it comes to the dispute over whether wartime Pope Pius XII did enough-or not enough-to save Jews during the Holocaust.

We’ve already written how Pius, 50 years after his death, continues to overshadow Catholic-Jewish relations. The Holocaust Museum says there’s an easy answer: open up the Vatican archives to historians and other interested parties so they can judge for themselves what Pius did, didn’t do or could have done:

“The United State Holocaust Memorial Museum views with concern recent indications that definitive conclusions are being drawn regarding the record of Pope Pius XII during the Holocaust. Such pronouncements, and any actions that might follow, can only be substantiated when the archives of the Vatican from this period are fully opened to the public for in-depth scholarly research.”
