Saint Catherine of Siena was a young Dominican laywoman who, in an age shaped by war, Church crisis, and male power, dared to speak to popes, cardinals, and rulers. In this episode of Footprints of Holiness, we follow her intense life: her early vocation, her service to the sick, her mystical experiences, her passionate letters, and her role in urging the pope’s return from Avignon to Rome. This is a story about faith, courage, words, inner reform, and the strength of a young woman who did not ask permission to obey God.
