Interesting to note that there was a time, not so long ago - where Catholic marriages were not recognized by the civil authorities in Italy. I foresee this will return, where the state will not accept marriages performed by the Catholic church.
The next stage of normal European transformation is the move from the large nation-state to the small principality with idiosyncratic rules.
That's usually set off by some sort of calamity of horrendous proportions.
Just a matter of time.
