Who Was St. John of Capistrano?
Giovanni da Capistrano was born on June 24, 1386, at Capistrano in Abruzzo. He studied law, served as governor, and entered the Franciscans after widowhood. St. Bernardine of Siena shaped his preaching on the Holy Name.
Pope Callistus III sent him to preach a crusade; at Belgrade in July 1456 his prayers and morale bolstered John Hunyadi's victory. John died of plague at Villach on October 23, 1456, and was canonized in 1690. Feast October 23.
Upon his release from prison, John experienced a profound conversion. In 1416, at the age of thirty-one, he entered the Franciscan community at Perugia, leaving behind his successful career and worldly ambitions. This dramatic change of life demonstrates the power of God's grace to transform even the most accomplished individuals and redirect their talents for the service of the Kingdom.
John and St. James of the March were fellow students under the guidance of St. Bernardine of Siena, one of the most important Franciscan reformers of the time. Under Bernardine's influence, John was inspired to institute the devotion to the Holy Name of Jesus and His Mother, a devotion that would become central to Franciscan spirituality and spread throughout Europe.
