Here are some authentic prophecies regarding the Great Monarch and Holy Pope. I took them from Desmond Birch's "Trial, Tribulation and Triumph". Mr. Birch is reliable because he only used fully approved sources which can't be said of others. These are only a few but there are many more. I post more later when I have more time.
Saint Cataldus of Tarentino (c. 680): "The Great Monarch will be in war till he is forty
years of age; a king of the House of Lily, he will assemble great armies and expel
tyrants from his empire. He will conquer England and other island empires.
Greece he will invade and be made a king thereof. Clochis, Cyprus, the Turks and
barbarians he will subdue and have all men to worship the Crucified One. He will at
length lay down his crown in Jerusalem."
Saint Caesar of Arles (469-543): "When the entire world, and in a special manner
France, and in France more particularly the provinces of the North, of the East, and
above all that of Lorraine and Champagne, shall have been a prey to the greatest
miseries and trials, then the provinces shall be succored by a prince who had been
exiled in his youth, and who shall recover the crown of the lilies.
"This prince shall extend his dominion over the entire universe. At the same time
there will be a Great Pope, who will be most eminent in sanctity and most perfect in
every quality. This Pope shall have with him the Great Monarch, a most virtuous man,
who shall be a scion of the holy race of the French kings.
“This Great Monarch will assist the Pope in the reformation of the whole earth.
Many princes and nations that are living in error and impiety shall be converted, and
an admirable peace shall reign among men during many years because the wrath of
God shall be appeased through repentance, penance and good works.
“There will be one common law, one only faith, one baptism, one religion. All nations
shall recognize the Holy See of Rome, and shall pay homage to the Pope. But after
some considerable time fervor shall cool, iniquity shall abound, and moral corruption
shall become worse than ever, which shall bring upon mankind the last and worst
persecution of Antichrist and the end of the world."
Saint Hippolytus (died 235): "The Great French Monarch who shall subject all the
East shall come around the end of the world."
Blessed Ruhunns Maurus (died 856): "Our principal doctors agree in announcing to
us that toward the end of time one of the descendants of the kings of France shall
reign over all the Roman empire, and that he shall be the greatest of the French
monarchs, and the last of his race.
"After having most happily governed his kingdom, he will go to Jerusalem, and
depose on Mount Olivet his scepter and crown. This shall be the end and conclusion
of the Roman and Christian Empire."
Monk Adso (died 992): "Some of our teachers say that a King of the Franks will
possess the entire Roman Empire. This King will be the greatest and last of all
monarchs, and after having prosperously governed his kingdom he will come in the
end to Jerusalem and he will lay down his scepter and his crown upon the Mount of
Olives. This will he the end and consummation of the Empire of Rome, and
immediately afterwards Antichrist will come."
Venerable Bartholomew Holzhauser (died 1658): "The fifth period of the Church, which began circa 1520, will end with the arrival of the Holy Pope and of the powerful Monarch who is called "Help from God" because he will restore everything in Christ.'
St. Francis of Paula (15th Century): "From your lordship, (here he is speaking of a future descendant), shall be born the great leader of the holy militia of the Holy Spirit, which shall overcome the world, and shall possess the earth so completely that no king or lord shall be able to exist, except he belongs to the Sacred Host of the Holy Spirit. These devout men shall wear on their breasts, and much more within their hearts, the sign of the living God, namely, the cross. He shall destroy all tyrants and heresies. There will be one fold and one shepherd. He shall reign until the end of time. On the whole earth there will be twelve Kings, one Emperor and one Pope."
