I believe there will be many modernists who will be quite surprised to find out that there is, indeed, a Purgatory and a Hell.
The modern world would have us all believe that we die and go straight to heaven.
Not so as referenced in the readings for All Saints Day.
Those in white garments have washed them clean in the Blood of the Lamb. (paraphrasing from the Book of Revelation)
Don’t worry, all the genuises who are smarter than the Popes and St.s Augustine, Aquinas, Benedict, etc etc etc will be along to say they know better. LOL
