Mark Shea on what to watch out for (scroll down a bit)
There are two sides to every great sin. There is the sin itself and also the effect the sin has on us. As a layman, there's precious little I can do about the sins of bishops like Krenn. However, there is something I can do about my reaction to people like Krenn. I can live in the love of Christ or I can be filled with rage and bitterness and let it destroy me. Basically, I want to say that I firmly believe God means for us to be healed of our bitterness (both as individuals and as a Church). He does not want the power of sin to destroy us, including the sins of other people and our own choice to cherish bitterness toward them.
