St. Kate of Siena

Catherine of Siena was born around 1347 in Siena, a city-state in medieval Italy, the youngest of about twenty-five children in a family that worked in the wool-dyeing trade. From an early age, she described having extraordinary mystical experiences, including what she believed was a vision of Christ in glory. Around age sixteen, against her family's wishes, she joined the Dominican Third Order (also known as the Mantellate), remaining a laywoman and living at home rather than entering a convent. She committed herself to a life of prayer, poverty, and service to the poor, which became the foundation of her spiritual vocation.

Her reputation for holiness and her gift for counsel drew a wide circle of followers, whom she called her 'famiglia.' She undertook a ministry of consolation to the sick and the condemned, including those on death row, and corresponded with an extraordinary range of people, from ordinary citizens to kings, queens, and the pope. During the Western Schism (1378–1417), when rival claimants to the papacy divided the Church, Catherine became one of the most influential voices arguing for the return of the papacy from Avignon to Rome and for the reform of clergy. She traveled to Avignon in 1376 to plead her case directly with Pope Gregory XI, whose eventual return to Rome she is credited with influencing.

Catherine's literary output was substantial and is the reason she became one of the few women to be recognized as a Doctor of the Church. Her masterwork, 'The Dialogue of Divine Providence,' is a spiritual treatise presented as a conversation between the soul and God, articulating her theology of divine love, truth, and the 'mystical body of Christ.' She also wrote hundreds of letters, many of which have survived and are studied for their political and spiritual insight, and dictated a series of prayers, including the famous 'Prayer of Catherine.' She is traditionally said to have received the stigmata (the wounds of Christ) in a private mystical experience, though, as with many medieval accounts of stigmata, the historical evidence is uncertain.

Catherine died on April 29, 1380, in Rome, at the age of about thirty-three, after suffering a stroke. Her body was later translated to the church of Santa Maria sopra Minerva in Rome. She was canonized in 1461 by Pope Pius II. In 1970, Pope Paul VI declared her a Doctor of the Church, making her one of only a small number of women to hold that title, alongside Teresa of Ávila and Thérèse of Lisieux. Her feast day is celebrated on March 5 in the Roman calendar, traditionally associated with the translation of her relics, while April 29 is observed as the anniversary of her death. She is the patron of Italy, of those ridiculed for their piety, and is often invoked by those who suffer from illness.

Her legacy is profound and ongoing. She is one of the patron saints of Italy and the city of Siena, and her writings remain required reading in many Catholic seminaries. The medieval Church's female theologians—a tradition long undervalued—have found a powerful voice in Catherine, and modern interest in her thought has only grown. She is also remembered for her bold political engagement at a moment of institutional crisis, and for modeling a form of lay spiritual authority that was unusual for a woman of her time.
