John L. Allen, Jr., the ubiquitous fair-minded former Rome correspondent for the lefty National Catholic Reporter in his weekly flash as a very good piece on, get this… why Pope Pius XII ought to be beatified immediately.
A significant block in the Catholic church, including much of its senior leadership, has a strong conviction that Pius XII is a saint and should be formally recognized as such; In other sectors of opinion, including much of the Jewish world, there is an equally strong conviction that Pius XII failed in his moral responsibilities during the Holocaust; No new evidence, or new historical perspective, is likely to alter those convictions; The primary force keeping this debate alive in the media, and making it a source of turbulence in Catholic-Jewish relations, is the question of possible sainthood.
Assuming those four premises are accurate, it seems to follow that there are only two ways out: Either Catholicism renounces sainthood for Pius XII, or we get it over with. Since the former is unlikely, the latter may be the best available option — and the sooner, the better. The alternative is allowing an endless cycle of point/counter-point exchanges to coarsen conversation and harden feelings.
He also has a very good summary of recent events, books, addresses about Pius XII on both sides of the issue.
Remember that in May the Congregation for Causes of Saints presented their decree super virtutibus for Servant of God Eugenio Pacelli. The Holy Father has yet to approve it.
