Catherine of Siena Bust

Catherine of Siena addressed popes and rulers with an authority that came from religious conviction rather than public office. Her letters called for personal reform. They also intervened in urgent Church affairs. She was a Dominican tertiary, a lay member of the order’s wider religious community, rather than a cloistered nun.

Born in Siena in 1347, Catherine became associated with the women known as the Mantellate. Her spiritual teaching survives in letters and in the work generally called the Dialogue, whose literary form places a soul in conversation with God. Mystical experience shaped her practical counsel.

Catherine urged Gregory XI to return from Avignon to Rome in 1376. The papacy’s return had political causes and preparations beyond her intervention, so she should not be credited with accomplishing it single-handedly. Her involvement nevertheless placed a woman without formal ecclesiastical office inside a central dispute of European politics.

Catherine spent her final years supporting Urban VI during the Western Schism and died in Rome in 1380. Her later recognition as a Doctor of the Church honors theological teaching. It should be distinguished from the formal authority she was permitted to exercise during her lifetime.
