Biography
Catherine of Siena was born on March 25, 1347, in Siena, Italy, into a large family. Drawn to Christ from childhood, she vowed herself to God while still young and resisted her parents’ plans for marriage, choosing instead a life of prayer and service. She joined the Mantellate, a lay group shaped by Dominican spirituality, and quietly embraced austere penance while caring for the sick and poor with remarkable tenderness.
As her love for the Church deepened, Catherine’s hidden life blossomed into a public mission. Through fearless letters and counsel, she urged conversion of heart and worked for peace among Italian cities. Her influence helped Pope Gregory XI return the papacy from Avignon to Rome, and during the turmoil of the Great Western Schism she defended unity and fidelity to the pope. Near the end of her short life, she dictated her great spiritual work, The Dialogue, along with many prayers and letters that continue to nourish the faithful.
Venerated as a Doctor of the Church, she is patroness of Italy and Europe. Her feast day is April 29.
