“after which the seven hilled city will be destroyed and the dreadful Judge will judge the people.”
One of the great tip-offs of the slanderous nature of Luther’s is that he didn’t know the geography of Rome, despite basing his deceit on his supposed visit there. The Vatican is in exile from Rome, on an eighth hill, across the River Tiber, where the Romans expelled St. Peter’s remains to. Thus, prior to Luther, Catholics awaited the destruction of Rome as representing the destruction of all things evil, without any disloyalty to the Bishop of Rome, who is the Pope.
The other portions of the prophecy should make plain that Peter the Roman is a virtuous Catholic who upholds the truth of the Catholic church.
Incidentally, that final clause of Malachy’s prophecy is recorded in a different handwriting than the rest.
Depending on how one counts hills, there could be up to 9 inside the walls of 100 AD Rome.
The Vaticano is on the western side of the Tiber as you say, and was not inside the walls of 100 AD Rome.
If that is so, then the current pope is the last pope. No?
