Catherine of Siena was a fourteenth-century Italian mystic, theologian, and political activist who, despite being a woman with no formal education or institutional authority, became one of the most influential figures in the history of the Catholic Church. She dictated hundreds of letters to popes, kings, and military leaders. She helped persuade the Pope to return to Rome from Avignon. She was declared a Doctor of the Church — one of only four women to receive the honor.

The Visions

Catherine began experiencing mystical visions at the age of six and took a vow of virginity at seven. She spent three years in almost total seclusion in a small room in her family's house, praying and fasting to extremes that alarmed her family. When she emerged, she did not retreat to a convent. She entered public life, caring for the sick, ministering to prisoners, and gradually attracting a circle of followers who recognized her spiritual authority.

The Letters

Catherine dictated over four hundred letters that survive — to popes, cardinals, queens, soldiers, and ordinary people. She wrote to Pope Gregory XI telling him to return the papacy from Avignon to Rome, and she did not mince words. She called him to courage and accused him of cowardice. The remarkable thing is that he listened. Gregory returned to Rome in 1377, ending the Avignon papacy, and Catherine's influence was a significant factor.

The Mystic and the Activist

What makes Catherine unusual among medieval mystics is that her contemplative life fed directly into political action. She did not choose between prayer and the world. She insisted they were the same thing. Her mystical experiences gave her the authority and the courage to confront the most powerful men in Christendom, and her political work was understood as an extension of her spiritual vocation.
