In the New Testament, Jesus Christ, Our Lord, said: "And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, by reason of the confusion of the roaring of the sea and of the waves; Men withering away for fear, and expectation of what shall come upon the whole world. For the powers of heaven shall be moved." (Lk. 21: 25-26) That is an infallible prophesy.

Speaking of comet prophecies, here is another one from St. Hildegard of Bingen (d. 1179 A.D.):

"Before the Comet comes, many nations, the good excepted, will be scoured with want and famine. The great nation in the ocean that is inhabited by people of different tribes and descent by an earthquake, storm and tidal waves will be devastated. It will be divided, and in great part submerged. That nation will also have many misfortunes at sea, and lose its colonies in the east through a Tiger and a Lion."

"The Comet by its tremendous pressure, will force much out of the ocean and flood many countries, causing much want and many plagues. All sea coast cities will be fearful and many of them will be destroyed by tidal waves, and most living creatures will be killed and even those who escape will die from a horrible disease. For in none of these cities does a person live according to the laws of God."
