St. Catherine was born in Siena in the year 1347, and she was the last of 25 children born to her parents. Her father was a wealthy man in the business of dying wool. From her earliest life, Catherine was a different kind of child, spiritually sensitive, and being part of such a large family, she liked to find times when she could be alone with God. It was at the age of six that she had some sort of vision near the Church of San Domenico in Siena. From that moment onward, she followed an even stricter path of devotion, and when she was only seven, she dedicated herself to Christ, taking a private and internal vow that she would never marry, but would live only to serve God.
She wanted very much to dedicate herself to Religious life, and although her parents initially resisted the idea, eventually her father gave in and allowed Catherine to follow whatever she felt God was calling her to do. In 1363, when she was just 15 years old, Catherine became a Dominican Tertiary, and wore the black cloak which designated her as a Dominican sister. She began to increase her charitable work, and spent a great deal of her time in a nearby hospital, caring for the sick.
Throughout this time she became known as someone who gave excellent spiritual guidance, as more and more people came to her, or wrote to her, for spiritual advice. In fact, she became well-known throughout the Church as a devout and gifted spiritual guide, and even as a mystic. It was during a visit to the city of Pisa that she received the stigmata in the presence of a crucifix hanging in the Church of Santa Cristina. As her spiritual fame grew, she was even asked to travel to different countries to act as a mediator for the papacy, which was at that time in exile at Avignon in France. She was very strong in voicing her opinion to Pope Gregory that he needed to bring the Papal Court back to Rome, and unify the Church. When the terrible situation arose with the false election of a second Pope, leading the Church to the edge of schism, she was instrumental in restoring the true Pope to his rightful place.
In the year 1380, when she was just 33 years old, St. Catherine died. She was eventually proclaimed to be a saint, and along with St. Francis of Assisi, St Catherine of Siena was proclaimed to be patron saint of Italy. Pope Paul VI conferred on her the title of Doctor of the Universal Church, and in 1999 she was proclaimed co-patron saint of Europe by Pope St. John Paul II.
O Merciful God, who gavest to thy servant Saint Catherine of Siena a wondrous love of the Passion of Christ: grant that, through her prayers; we thy people may be united to him in his majesty and rejoice for ever in the revelation of his glory; who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
