Toward the end of the 19th century and for a large part of the 20th century, various heresies will be propagated. The precious light of Faith will be extinguished in souls by the almost total corruption of customs. During this period there will be great physical and moral calamities, both public and private. The small number of souls who will secretly safeguard the treasure of Faith and virtues will suffer a cruel, unspeakable, and prolonged martyrdom.
