Mandatory retirement age for RC bishops is 75. Archbishop Chaput is 72, and not a cardinal.  The culture war he helps lead in the United States is not only a dubious way to spread the Good News, it has also been a continuous loser in public contests. The profound damage to the moral authority of the RC Church caused by the sex abuse scandals has deeply discounted the moral authority of the episcopacy even in his archdiocese, where he just completed a full court press to frustrate an effort in the Pennsylvania legislature to lift the statute of limitations on sex abuse in that state.  
The issue is this: what is the wise response to a legal and cultural regime which is inconsistent with Catholic doctrine-- persuasion or political power and control? Conversion, or the county sheriff?
