It’s the general opinion of the Church that because of the influence of the AntiChrist that survival for Traditional Catholics will be very difficult, so much so,  that at the end the world we will be divided as either Saints or Sinners. You have this in “The Catechism Explained” by Fr’s Spirago and Clark. 1921.  The other source is, “Fundamentals of Catholic Dogma,” by Dr. Ludwig Ott Page 485, 1955.

The purifying fire will not continue after the General Judgment.
Matt: 25: 34-41. No place in between here. St. Augustine says, “Let purification punishments be counted on only before that last and terrible judgment.” Dr. Ott

The existing universe will be destroyed by fire (?) and this fire will purge those who have yet to do penance for sin; and since there will be no purgatory after the Day (week) of Judgment the want of duration will be made up by the intensity of the pain… Fr’s. Spirago and Clark

That’s why Our Lord made it very clear when He said, and which I have quoted thousands of times, “And unless those days had been shortened, no living creature would be saved. But for the sake of the elect those days will be shortened.” The only thing I can add to this is God help us if He’s not talking about us.

Grace be with you, in Christ, Joseph
