St. John of Capistrano

A young governor of Perugia thrown into prison after a war, where through long hours alone he heard a call to religious life. He joined the Franciscan Observants, became a great preacher across Europe, and at seventy was sent to rouse Christians against the Ottoman advance. He preached cross in hand at the siege of Belgrade in 1456 and helped win a victory that saved central Europe.

Trained as a lawyer and briefly married before his imprisonment, John was transformed by a vision of St. Francis. He became a disciple of Bernardino of Siena, and his preaching drew crowds so vast that no church could hold them — he spoke in town squares, fields, and marketplaces, and conversions followed by the thousands.

He died on October 23, 1456, just three months after the triumph at Belgrade, worn out by the campaign and stricken with plague. His life spans the full arc from worldly ambition to radical poverty, from the courtroom to the battlefield, always in the service of a faith he had found in the silence of a prison cell.
