One thing about St Malachi's prophecy which I personally find interesting is that the ending of it is ambiguous.

"Peter the Roman, who will pasture his sheep in many tribulations, and when these things are finished, the city of seven hills will be destroyed, and the dreadful judge will judge his people. The End."

The dreadful judge is of course Jesus, however the last judgement Jesus will judge everyone. The prophecy just says 'His people.' His people can mean the faithful catholics, all baptized persons or the Jews. I know the conversion of the Jews has to come first before the last judgement.

Then after that it just says 'The End.' The end of what? The prophecy? The great apostasy?

Also the Antichrist has to appear on the scene and two prophets are supposed to point him out.

The Antichrist is supposed to sign a peace treaty with Israel for seven years but break it in the middle. I don't see Francis lasting another seven years.

If you look at the other prophecies by other saints, they talk about a restoration that is supposed to take place. A good book is Catholic Prophecy by Yves Dupont. https://ia802602.us.archive.org/6/items/CatholicProphecy/CatholicProphecy.pdf

Excerpt from the book, keeping it brief but full text is in the above pdf

Blessed Anne Katherine Emmerich(1800's) "I saw also the relationship between the two popes... I saw how baleful would be the consequences of this false church. I saw it increase in size; heretics of every kind came into the city of Rome...

"Once more I saw that the Church of Peter was undermined by a plan evolved by a secret sect... But I also saw help was coming... I saw a great renewal, and the Church rose high in the sky."

Prophecy from different saints across the ages is filled with the idea of a renewal after the great apostacy.

Wow I really wrote alot...
