Bonifacia Rodríguez y Castro was the co-foundress of the Religious Congregation of the Servants of St. Joseph, who developed the "Nazareth workshop" as both a new format for consecrated life and to help poor and unemployed women. They were an innovative foundation of Religious Sisters in Spain in the nineteenth century.

The Servants of St. Joseph form an international congregation of religious sisters in the Roman Catholic Church. It was founded by Saint Bonifacia Rodríguez-Castro on January 7, 1874, with the support and guidance of a Catalan Jesuit, Fr. Francesc Xavier Butinyà i Hospital, S.J., in Salamanca, Spain, and named after Saint Joseph.
