Saint Catherine of Siena, a 14th-century mystic, famously avoided the sin of gluttony by extreme means. She would consume only herbs and, when forced to eat more, would drink pus from the sores of plague victims, describing it as 'sweeter or more exquisite' than any food. She believed this combined the principles of service and suffering—cleaning wounds and enduring pain. Catherine eventually died of starvation at age 33.
Medieval Solutions for Modern Problems
In his new book, historian Peter Jones explores how medieval men and women avoided the seven deadly sins: pride, envy, anger, sloth, avarice, gluttony, and lust. Jones argues that these ancient concepts can still guide us toward a good life today. Before therapists, people turned to priests and spiritual guidebooks to overcome moral failings.
Envy as a Motivator
Jones recounts his own experience teaching in Siberia, where loneliness and depression led him to medieval advice. He found that envy can be useful when it highlights what we truly desire, such as a better job. However, envy becomes toxic when it focuses on others' failures rather than our own blessings. A 13th-century guidebook advises 'modifying our attention' to rejoice in rivals' triumphs, turning envy into compassion.
Lust and Redirection
Lust, according to Jones, is the least deadly sin because it seeks connection. Problems arise when it reduces people to objects. Saint Bernard of Clairvaux suggested redirecting lustful feelings toward spiritual union with Jesus. Some medieval women, like Angela of Foligno, took this literally: she would strip before a cross and, feeling an intense inner fire, burned her genitals with a candle to overcome lust.
Why Medieval Advice Still Works
Jones presents these examples with wit and clarity, making medieval wisdom accessible. He argues that keeping the seven deadly sins in mind can be an effective tool for self-improvement, even in the 21st century. His book offers a unique blend of history and practical advice, showing that the past holds timeless lessons for living well.
