Prophecy of Blessed Anna Maria Taigi who was Beatified by Pope Bendedict XV in 1920
"God will send two punishments: one will be in the form of wars, revolutions and other evils; it shall originate on earth. The other will be sent from Heaven. There shall come over the whole earth an intense darkness lasting three days and three nights. Nothing can be seen, and the air will be laden with pestilence which will claim mainly, but not only, the enemies of religion. It will be impossible to use any man-made lighting during this darkness, except blessed candles. He, who out of curiosity, opens his window to look out, or leaves his home, will fall dead on the spot. During these three days, people should remain in their homes, pray the Rosary and beg God for mercy." "All the enemies of the Church, whether known or unknown, will perish over the whole earth during that universal darkness, with the exception of a few whom God will soon convert. The air shall be infected by demons who will appear under all sorts of hideous forms."
All light in the heavens will be extinguished, and there will be great darkness over the whole earth. Then the sign of the cross will be seen in the sky, and from the openings where the hands and the feet of the Savior were nailed will come forth great lights which will light up the earth for a period of time. This will take place shortly before the last dayExodus chapter 10
Then the LORD said to Moses: Stretch out your hand toward the sky, that over the land of Egypt there may be such darkness that one can feel it. So Moses stretched out his hand toward the sky, and there was dense darkness throughout the land of Egypt for three days.Catholic Mystic and Stigmatist Marie Julie Jahenny of La Fraudais, France
There will come three days of continued darkness. The blessed candles of wax alone will give light during the horrid darkness. One candle will last for three days, but in the houses of the godless they will not give light. During those three days the demons will appear in abominable and horrid forms; they will make the air resound with shocking blasphemies.
“The lightning will penetrate the homes, but will not extinguish the light of the blessed candles; neither wind nor storm nor earthquake will extinguish it. Red clouds like blood will pass in the sky, the crash of thunder will make the Earth tremble; lightning will flash through the streets at an unusual time of the year; the Earth will tremble to its foundations; the ocean will cast its foaming waves over the land, the Earth will be changed into an immense cemetery; the corpses of the wicked and the just will cover the face of the Earth.”
“Keep your windows well covered. Do not look out. Light a blessed candle, which will suffice for many days. Pray the rosary. Read spiritual books. Make acts of Spiritual Communion, also acts of love, which are so pleasing to Us. Pray with outstretched arms, or prostrate on the ground, in order that many souls may be saved. Do not go outside the house. Provide yourself with sufficient food. The powers of nature shall be moved and a rain of fire shall make people tremble with fear. Have courage! I am in the midst of you.”
