In this episode of Catholic Expression, Father Greg and Christi explore the virtue of chastity, using the analogy of a souped-up car to illustrate the power of sexual desire. They discuss the definitions of chastity, celibacy, and abstinence, and emphasize the importance of living chastity in a society that often promotes lust. The conversation highlights the roadblocks to chastity and offers practical ways to live out this virtue.
