What perps? This is an allegation.
Furthermore, there's no statement in the article which indicates that clerics were involved other than the one implicating the now deceased Vatican archivist. The Vatican has many lay employees and in fact, the linked Daily Mail article indicates that a foreign embassy to the Vatican was implicated.
One can argue either way where this should be posted. I post articles on all matters Catholic and I post them to the religion forum as a matter of course, as you'll see if you scroll down the thread.
Glad you found it.
There are some folks who don’t read, just react. They don’t read the Bible, just give their guesses on what it is — and then they lecture Catholics/Orthodox/Lutherans etc. on their rot. When you point out to them how little they read or know, they get huffy and jump away.
