This is in reply to your 8/20 post RE: Donna Danna: 08.13.23: Mystery, Babylon (fivedoves.com)  According to the article about the history of the Vatican City at Vatican City (history.com) the Vatican was a part of Rome and did not become a sovereign nation until 1929.  So yes, the Vatican would fit Mystery Babylon, but I think all the present day apostate churches are also a part of Mystery Babylon because they are also harlots who are lying with Satan with their false doctrines.
