The Roman-Ruthenian Supreme Pontiff, as the Latin Orthodox successor of St. Peter the Apostle, is the perpetual and visible foundation of unity among the bishops and faithful of the Church.
The office unites the Petrine ministry of Supreme Pontiff, the patriarchal jurisdiction of Catholicos, and the historic temporal custodianship of the Prince-Bishop of Rome-Ruthenia.

Apostolic Continuity Preserved in the Archives
Among the preserved archival holdings of the Pontifical Chancery are ecclesiastical instruments connected to the early juridical and patriarchal development of the United Roman-Ruthenian Church and issued by authorities of the Holy See of Rome.
These pertain to the reception of apostolic jurisdiction, patriarchal autocephaly, and papal dignity within the continuing Orthodox and Catholic tradition now embodied in the Roman-Ruthenian Church and State. These documents are part of the sacred patrimony of the Church, preserved with care and continuity.
