The Society of Pius IX is a fraternity of clergy and religious with origins in the Catholic and insular traditions. It endeavors to provide a faithful witness to Apostolic Doctrine and Discipline, particularly as regards Matrimony and Holy Orders, and works towards the restoration of the Church to unity of structure, doctrine, and discipline within the spiritually generous framework articulated by St. Vincent of Lerins in his Commonitorium as well as the Canons of Trullo.

The Society provides a common spiritual and ecclesial life for clergy and religious serving in parochial ministries, chaplaincies, and missions. To further its mission, the Society provides continual theological and liturgical formation for its clergy, together with the resources and conferences proper to their ministry, and assists in their placement among parishes and communities in need of clergy.

We affirm the fullness of the Catholic faith, with a special emphasis upon the ancient traditions and patrimony of the Church, especially as received in the Western and insular Churches.
