Fr. Alban Butler relates: St. Lupus could not see this soul perish [a particular sinner], but wrote to St. Sidonius, then bishop of Clermont, a strong letter so prudently tempered with sweetness, that Gallus by reading it was at once terrified and persuaded, and immediately set out to return to his wife. Upon which St. Sidonius cried out: “What is more wonderful than a single reprimand, which both affrights a sinner into compunction, and makes him love his censor!”
