There are many historical prophecies that people use to promote a point of view in this, the beginning of the third millennium. Unfortunately not all are as genuine as the promoters would like them to be.
And if a prophecy sounds modern, then it probably is - modern!
One crucial test for any prophecy is: where's the original text? If that's not available, then the prophecy HAS to be considered doubtful.
One example is the 'Secret Register of Prophecies' of John of Jerusalem. Now depending on the version you encounter, that is John of Jerusalem of the 12th century, or the bishop of the same name of the 3rd/4th century.
And the original text?
If its from the 12th century we would be expecting a Latin text.
If from the 3rd/4th century Greek, may be Aramaic?
But what have we got?
A text in modern French with a sprinking of archaic words, 'translated' (from what?) by a Russian professor, M.Galvieski, and published in France in 1994 by Editions Jean-Claude Lattes.
OK, so we have no original text, just a modern French rendition. Hmm.
