The Oratory of St. Augustine in Philadelphia is an ecumenical community of traditional, Catholic Christians centered on the solemn celebration of the Holy Eucharist with incense and chant. The Oratory of St. Augustine falls under the Diocese of Pennsylvania, a Suffragan Diocese of the Archdiocese of the United States of the Old Catholic Confederation. The Oratory also serves as the Chapel of the President of the Synod of Bishops of the Old Catholic Confederation.
The Old Catholic Confederation is an ecumenical union of orthodox Old Catholic jurisdictions in the United States. As an Old Catholic Church, the OCC is founded upon the ancient Church, the sacred Scriptures, the teaching of the Fathers, and the first Seven Ecumenical Councils of the One, Holy, Catholic and Apostolic Church. As traditional Old Catholics, we believe that Old Catholicism is Western Orthodoxy. The Old Catholic Confederation is governed by a Synod of Bishops whose ecclesial authority derives from the Authority of our Lord and Savior, Jesus Christ, through Apostolic Succession.
