3 Days of Darkness prophecy in the Last Days

The most spectacular aspect of the Act of God will be the three days of darkness over the whole earth. The Three Days have been announced by many mystics, Anna-Maria Taigi, Elizabeth Canori-Mora, Rosa-Colomba Asdente, Palma d'Oria, in Italy; Father Nectou, in Belgium; St. Hildegard, in Germany; Pere Lamy, Marie Baourdi, Marie Martel, Marie-Julie Jahenny, in France. Many of Saints [like St. Columba d. 597 A.D.
have announced the Three Days.

of the Three Days of Darkness; where at least half to three quarters of the world's population will be killed by God's Just Wrath.
the Gospel [Evangelium]: the Holy Ghost will speak to many in the Latter Days.

Moreover, when an identical prophecy has been made by widely separated people in time and space, when this particular prophecy was accompanied by other predictions which have already come to pass, and when the holiness of the mystics in question has been recognized by the Church, we would be foolish indeed not to believe that the prophecy must come to pass. Such is the case concerning the Three Days of Darkness. How else could we explain that an illiterate peasant woman of Brittany is describing the very thing that another mystic in, say, Germany or Italy is also describing.

After the three days of darkness, St. Peter and St. Paul, having come down from Heaven, will preach in the whole world and designate a new Pope. A great light will flash from their bodies and will settle upon the cardinal who is to become Pope. Christianity, then, will spread throughout the world. He is the Holy Pontiff, chosen by God to withstand the storm. At the end, he will have the gift of miracles, and his name shall be praised over the whole earth. Whole nations will come back to the Church and the face of the earth will be renewed. Russia, England, and China will come into the Church."
