The Felician Sisters (officially known as the Congregation of Sisters of St. Felix of Cantalice Third Order Regular of St. Francis of Assisi (CSSF)) is a religious institute of pontifical right whose members profess public vows of chastity, poverty, and obedience and follow the evangelical way of life in common. This active-contemplative religious institute was founded in Warsaw, Poland, in 1855, by Sophia Truszkowska, and named for a shrine of St. Felix, a 16th-century Capuchin saint especially devoted to children.
When Sophia Camille Truszkowska was twelve years of age, her family moved to Warsaw where her father took up the position of Registrar of Deeds. Initially, she wished to become a Visitation nun, but in 1854 she joined the Society of St. Vincent de Paul and began to work among the poor. With her father’s financial assistance, she rented a flat in order to care for several orphaned girls and aged women. Sophia was joined in her work by her cousin and close friend, Clothilde Ciechanowska. Later that year they became lay members of the Franciscan Third Order. On the Feast of the Presentation of the Blessed Virgin Mary, November 21, 1855, while praying before an icon of , they solemnly dedicated themselves to do the will of Jesus Christ in all things. Hereafter this was recorded as the official founding day of the Congregation of the Sisters of St. Felix of Cantalice.
People began calling them “Sisters of St. Felix.” in reference to the shrine of St. Felix of Cantalice at a nearby Capuchin church. They were popularly referred to as “Felician Sisters,” the name by which the community is still known. In 1857, she and several associates took the Franciscan habit. Sophia took the new name of Mary Angela. In 1869 health problems caused her to withdraw from administration of the Congregation. She spent the next thirty years on assignments in the garden and greenhouse, tending flowers for the chapel and in the liturgical vestment sewing room, embroidering altar cloths and chasubles. She died at the provincial house in Kraków on October 10, 1899. Mother Mary Angela Truszkowska was beatified by Pope John Paul II in 1993.
