The ideology that every single baptized person is called to carry out their universal mission of the church began in the person of St. Vincent Pallotti. His foundation - the Union of Catholic Apostolate (UAC) - began in 1835 with a small group of Roman clergy and lay individuals who wanted to more fully participate in the mission of the church.

St. Vincent knew that the clergy and religious could not do all the work of the Church. As a priest ahead of his time, he encouraged the laity to collaborate in the work of the Union by following their personal and unique baptismal vocation. The Pallottine Sisters, Brothers and Priests were founded a short time later.

The work of the Union of Catholic Apostolate began simply by ministering to the victims of the cholera epidemic. Later they opened schools and orphanages, ministered to the sick, raised money for the missions, and remained available to meet other needs that arose.

As Pallottine Missionary Sisters, we are collaborators in the UAC. Our charism is to spread the Gospel message and to help others acknowledge their gifts and their baptismal call. Our goal is the same today as it was in Vincent's time -
