Setting aside The Statute of Limitations, on which I agree with Joe, the Crimes were not committed BY the Church, but by adult males who happened to be employees OF the Church.

Should the law enforcement agencies be held responsible for the actions of every bent or sexually abusive policeman?
The Church can only be faulted on improper vetting of priests(they should have spotted the time bomb within their organisation) and a limited and desperate attempt at damage limitation.
