The Three Days of Darkness - Real or Fake?

Many of the messages about preparing for the Three Days of Darkness come from some of the modern false apparitions, if I recall correctly.  I believe that the devil, via many of these false apparitions, wants to convince everyone to prepare for a temporal chastisement, when the spiritual chastisement has already befallen them, and the faith has been ripped away from them, and they are attending a false Mass, and following a non-Catholic sect.  If Three Days of Darkness do occur, the only preparation that a Catholic needs to make is to be in the state of grace and hold the fullness of the Faith without compromise. The answer to your next question is that we are definitely in the Great Apostasy now, the time just preceding the Second Coming of Christ.
