I remember reading that speech of Enda Kenny over and over, and watching replays of his delivery.  Finally, someone with governmental power called out the Vatican for its claim of special exemption to following laws of the country in which they didn't just exist, but in which they had played an powerful role in both society and government.  The Royal Commission did the same kind of in depth investigation as Ireland had done.  

I think the impact in both countries was profound - at least on the Catholic people.  I don't know if the church itself, acting through the bishops and the bishops conferences, really did much to change themselves.  Oh, they implemented important and necessary procedures to protect children now and in the future.  But it doesn't seem to me that they even looked at themselves and why they failed so utterly in the first place.  What happened is systemic to what and how they (the hierarchical church) think and how they have organized themselves.  They don't get it.
