Why I don't post much on the scandals
1. Plenty of other people are saying about everything that needs to be said: Amy Welborn, Eve Tushnet, Rod Dreher (at National Review and National Review Online), and many others.
2. There are many ways to respond to moral failures and scandals within the Church. One is evidenced by people like St. Catherine of Siena, and is seen in the strong words of people like Amy, Eve and Rod. Besides that reaction, though, is another one, evidenced by people like St. Ignatius of Loyola: to not say much and focus on one's own sanctity and to do good works and penance to heal the damage done by sin. (Obviously people like St. Catherine and her modern 'disciples' would embrace this as well; the options are not exclusive.) This is the path which I personally prefer. It's simply the one I feel most comfortable with, for a number of reasons.
I say this because I don't want my "silence" to give the wrong impression. What has gone on is wrong, simply put, and those responsible must be held accountable. But my personal response -- among many legitimate and excellent options -- is to focus on rooting out my own failings and to strive after my own holiness, and in so doing to help the Body of Christ in a time of special need.
