I can't see any reason to use American Dating format for an article that intimately concerns an Italian, where International Dating is more appropriate. Not without a good reason. Sure, the Roman Catholic Church is a global institution, but so to is the British Commonwealth, and I can't see any reason to use American Dating in the biographical article on the current head of the Commonwealth, Queen Elizabeth II. Or for any previous British monarch, including the time when they reigned over what is now the U.S.. When there's an American (or Filipino]] pope, then American Dating format would be appropriate for their biographical article. I've been working my way through the popes, changing the date formats to International Dating, and I'd appreciate that my careful work on this article be restored. Including unlinking dates, please.
