Fr. Charles Arminjon's
End of the Present World and the Mysteries of the Future Life (Sophia Institute, 2008), was a life-changer for St. Therese of Lisieux. The book consists of a series of conferences given by Fr. Arminjon at the Cathedral of Chambery (Savoy). I quote from one of the notes:
St. Ambrose held that a life free of trials was a certain sign of divine malediction, and said, "I should not wish to live for a single night under the roof of a man who has never suffered." Another saint said, "Why attach any importance to afflictions? Temporal life is but a transition. A whole lifetime of pain in this world is of no more consequence than an uncomfortable night in a bad hostelry."
