They speak of a final pope, Petrus Romanus, after Pope Benedict, and after his reign, will come the end of the world.
But scriptures specifically stated:
"But of that day or hour, no one knows, neither the angels in heaven, nor the Son, but only the Father. Be watchful! Be alert! You do not know when the time will come." (Mark 13:32-33)

26"Just as it was in the days of Noah, so also will it be in the days of the Son of Man. 27People were eating, drinking, marrying and being given in marriage up to the day Noah entered the ark. Then the flood came and destroyed them all.

Luke 17:28-30
28"It was the same in the days of Lot. People were eating and drinking, buying and selling, planting and building. 29But the day Lot left Sodom, fire and sulfur rained down from heaven and destroyed them all.

30"It will be just like this on the day the Son of Man is revealed.
Seems to indicate that it will happen out of the blue, no indication.

So if Jesus does not know, why would this be revealed to st. Malacy?

please, no anti catholic spam.
a priest mentioned that there is no indication of the end of the world.
No numbers, or symbolism could make any indications.
