Dominican mystic, Doctor of the Church, and co-patron of Europe who counseled popes

Catherine was a Dominican tertiary who never held office and could barely write, yet she became one of the most influential figures of fourteenth-century Italy. She urged the return of the popes from Avignon to Rome, dictated a body of letters and a great spiritual work, and was later named a Doctor of the Church and a patron of Europe.

Born in Siena in 1347, one of the youngest in a large family, Catherine resisted plans for her marriage and at a young age joined the Mantellate, Dominican women who lived a life of prayer and charity while remaining in the world. After years of solitude and prayer at home, she came out to serve the sick and the poor of Siena, including during outbreaks of plague.

Around her gathered a wide circle of followers, and her counsel was sought far beyond the city. Unable to write easily herself, she dictated hundreds of letters to rulers, clergy, and ordinary people, and a long mystical dialogue with God that became known as The Dialogue of Divine Providence. She pressed for the reform of the clergy and for peace among the warring Italian cities.

Her most public work was her appeal to Pope Gregory XI to leave Avignon and return the papacy to Rome, which he did in 1377. She spent her last years in Rome amid the crisis of the Great Western Schism, worn out by penance and prayer, and died there in 1380 at thirty-three.

Catherine showed that a laywoman with no power but prayer and honesty could shape the life of the whole Church. Declared a Doctor of the Church in 1970 and a patron of Europe in 1999, she remains a model of courageous fidelity joined to deep mysticism.
