How can you say that you're not responsible?
It seems only fair to point out that the story also mentions how over a hundred Catholics in Holy Orders were killed for being born Tutsis, or standing up to the Hutu genocidal mobs, while it sounds like 3 or 4 priests have been legally accused of participating in the genocide. The actions of those handful had an unconscionable human cost, but it's worth keeping both numbers in mind.
What's far more worrying to me is the fact that the NPR piece starts with a familiar story. One of the priests currently standing trial in international court had been shuffled out of the country, even ministering in Europe under an assumed name. This person is accused of participating in the murder of 2,000 of his own parishoners.
The local archbishop denies that any priests were involved, in spite of the fact that some have been convicted by Rwandan and international courts.
Pope Benedict XVI does not need my advice on "where to start." There's plenty of good options. But it might not hurt to make an early acknowledgment that the members of the Church are subject to both canon law and the laws of the land. When a priest commits a crime, he needs to be subject to both ecclesiastical consequences and civil penalties. They deserve due process, of course, the presumption of innocence when possible, and even Christian charity. But we must not dare to be completely above the law.
The Berrigans did their time, as have countless other Catholics who committed civil crimes for religious conscience. It is an insult to our faith, and to the entire tradition of civil disobedience, to conflate "innocent until found guilty" with "innocent until found in Florence or Arizona."
This is how we reconcile being "a city on a hill" with "redering unto Caesar what is Caesar's." Most of us are not called to be separate, we are called to be more. We will hold up the martyrs who succeeded. We must hold accountable, in both worlds, those who have so spectacularly failed.
