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 jurisdiction of the Diocese of Pennsylvania of the Old Catholic Confederation of the United States.
The Old Catholic Confederation of the United States is an ecumenical union of orthodox, Old Catholic jurisdictions in the United States. As an Old Catholic Church, the OCCUS 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 our Lord and Savior, Jesus Christ, through Apostolic Succession.
