I think this report should be the trigger for a very broad discussion in the church: the WHOLE church, and not just the clerics.  It would seem to gut so much of what the bishops have told us, what they have done.  I cannot imagine curing this cancer on the church, without a major organizational and structural change.  

For the church's regular "defenders," I would hope this triggers a period of a serious pause for reflection.  The actions of the previous popes trigger, once again, that question of church teaching, and how it  might be used not as an attempt to understand the Divine, but as a means to protect the clergy, especially the hierarchy, from their own sins.  That is the card at the bottom of a house of cards that has caused so many to question their faith as a result of the scandal.  

My hat is off to those who prepared this study, and I hope it triggers some serious review of the studies issued here in the US,  It's time to talk about the truth, and deal with it.
