I haven't commented on the ongoing scandal in the Roman Catholic Church because it is too easy as an outsider to point fingers or be super self-righteous. Child abuse is a serious problem in society in general, not just in the Roman Catholic Church. My denomination is not exempt. A deep hypocrisy and credibility problem in the RCC is a problem for all Christians, not just those loyal to Rome.
All that is to say I think Hans Kung is exactly right in his recent open letter to Pope Benedict. Though I have no right to say what the RCC should do - I hope they listen to him.
