Matthew 24:21-23

New Catholic Bible

²¹ For at that time there will be great suffering that has not been equaled since the beginning of the world until now, and will never again be duplicated. ²² And if those days had not been cut short, no one would be saved; but for the sake of the elect they will be shortened.

²³ False Messiahs and False Prophets.“Therefore, if anyone says to you, ‘Look, here is the Christ,’ or ‘There he is,’ do not believe it.
