St. Catherine of Siena was a 14th-century mystic, theologian, and influential figure in the Catholic Church, known for her profound spiritual insights and commitment to social justice. A dedicated advocate for the reform of the Church and peace during a time of political strife, she played a key role in persuading Pope Gregory XI to return the papacy to Rome.  Canonized in 1461 and declared a Doctor of the Church in 1970, St. Catherine's legacy continues to inspire those seeking to live a life of faith and service. She is the patron saint of Italy, nurses, and those suffering from illnesses.
