St. Pacian of Barcelona 310-391
Remember that confession (exomologesis) extinguishes hell (gehennan) for you. And you may guess the intensity of hell from what is visible. Some of its chimneys boil away the greatest mountains by its subterranean fires. Etna in Sicily and Vesuvius in the Campania burn with unflagging balls of fire; and they will test us, sear us, devour us in an eternity of judgment, nor will they be finished after any number of ages. (Sermon Exhorting to Penance, 11)
