The Petrine dimension
The Pope is the visible head of the United Roman-Ruthenian Church and custodian of its Latin Orthodox Petrine inheritance, charged with preserving faith, unity, order, and Apostolic continuity.
The Holy Apostolic See of Rome-Ruthenia
The Roman-Ruthenian Papacy
One Petrine office in which spiritual jurisdiction and temporal custodianship are united in service to the Apostolic faith.
The office in brief
One office, two dimensions
The Roman-Ruthenian Pope stands within a jurisdictional Petrine succession and a temporal Petrine succession. These are distinct dimensions of one inherited office, brought together in the governance of the United Roman-Ruthenian Church and the custodianship of its historic patrimony.
The office and title of Roman-Ruthenian Pope were formally conferred in 2014 upon the Prince-Bishop of Rome-Ruthenia, together with full papal authority within his own jurisdiction. The Roman-Ruthenian Pope exercises that office as Supreme Pontiff of the autocephalous United Roman-Ruthenian Church, the Eastern Roman Church with Latin heritage.
A Petrine ministry expressed through Rome-Ruthenia
Spiritually and jurisdictionally, the Roman-Ruthenian Pope exercises the Petrine ministry within the autocephalous jurisdiction of the United Roman-Ruthenian Church, the Eastern Roman Church with Latin heritage. Temporally, he safeguards the sovereign, dynastic, cultural, and heraldic patrimony inherited through the Roman and Ruthenian successions.
The two dimensions belong to one office. The title Pope expresses the Petrine and pontifical ministry; Catholicos expresses patriarchal headship; and Prince-Bishop expresses the conjunction of ecclesiastical government with the temporal custodianship of the Pontifical Imperial State.
The patriarchal dimension
As Catholicos of Rome-Ruthenia, the Pope exercises patriarchal jurisdiction over the clergy, faithful, and constituent jurisdictions belonging to the Catholicate of Rome-Ruthenia.
The temporal dimension
As Prince-Bishop of Rome-Ruthenia, the Pope holds the temporal and dynastic custodianship joined to the Church through the Pontifical Imperial State of Rome-Ruthenia.
Spiritual and jurisdictional continuity
The Latin Orthodox Petrine succession
The Roman-Ruthenian Papacy is the present expression of the Petrine office within the United Roman-Ruthenian Church. In the Church’s ecclesiology, this is a jurisdictional succession: the transmission and exercise of Petrine authority within a distinct and continuing ecclesiastical jurisdiction.
This jurisdictional inheritance is more particular than episcopal ancestry. Apostolic succession identifies the sacramental lineage through which bishops were consecrated. Jurisdictional succession identifies the ecclesiastical office and authority that the Church continues. The Roman-Ruthenian Church traces that jurisdictional inheritance through the historic Roman line and understands its present institutional form as the contemporary expression of authority inherited from the ancient Petrine Church.
“Latin Orthodox” identifies the Church’s Western and Roman ecclesiastical inheritance within the fullness of Orthodoxy. Its liturgical life is principally Gallo-Russo-Byzantine while also preserving other Eastern and Western rites.
Ecclesial foundation
Succession, Grant, and Recognition
The Roman-Ruthenian Papacy is an ecclesiastical office grounded in inherited continuity and formally constituted through grant and recognition. Succession supplies the ecclesial foundation; grant confers the authority; and recognition acknowledges its legitimate exercise within the Church’s own jurisdiction.
Ecclesial Succession
The Apostolic, patriarchal, and jurisdictional successions of the United Roman-Ruthenian Church provide the continuing autocephalous ecclesial body within which the Petrine office is received and exercised.
Grant of Authority
Papal authority within the autocephalous Roman-Ruthenian jurisdiction was granted to the Prince-Bishop in connection with the Church’s established Apostolic continuity, recognized patriarchal status, and responsibility for its own governance.
Ecclesiastical Recognition
The Church’s preserved ecclesiastical instruments record that in 2014 the Prince-Bishop of Rome-Ruthenia was recognized by the Roman Cardinal Dean as coadjutor of the Roman Pope and granted full papal authority within his own jurisdiction. The 2014 act conferred papal status and authority upon the Prince-Bishop within the Roman-Ruthenian jurisdiction, building upon—and giving a new juridical expression to—the Church’s pre-existing Apostolic, patriarchal, and jurisdictional continuity.
“Apostolic succession answers the question, ‘From whom were its bishops consecrated?’ Jurisdictional succession answers the different question, ‘What ecclesiastical authority and office does this Church continue?’”
Roman-Ruthenian teaching on Petrine governanceHistorical and temporal continuity
The custody of Roman and Ruthenian patrimony
For centuries the historic Roman Papacy possessed ecclesiastical jurisdiction together with a temporal patrimony. Roman Pontiffs exercised sovereign prerogatives and bore temporal dignities bound to the political, cultural, and Christian inheritance of Rome.
The United Roman-Ruthenian Church holds that this historic patrimony passed into its custody through the Roman succession, including direct succession from Pope St. Leo X, and was joined to the inheritance of Ruthenia or Old Rus’. The Pontifical Imperial State of Rome-Ruthenia is the living institutional expression of that united temporal heritage.
In Roman-Ruthenian usage, the temporal successor of St. Peter is the custodian of the historic, non-sacramental patrimony associated with the Petrine office: its sovereign, dynastic, cultural, heraldic, and temporal inheritance.
Four records of continuity
The successions answer different questions
The Roman-Ruthenian inheritance is documented through several complementary lines. Each records a different aspect of ecclesiastical or historical continuity.

Custodia Petri
The Custody of Peter
The keys of St. Peter signify responsibility as well as dignity: the preservation of Apostolic faith, the continuity of ecclesiastical ministry, and faithful custody of the spiritual and historical patrimony entrusted to the Church.
Sacramental continuityApostolic succession preserves the episcopate received through the Apostles.
Jurisdictional continuityThe Latin Orthodox Petrine succession preserves the office and authority exercised within Rome-Ruthenia.
Temporal continuityTemporal succession preserves the historic patrimony associated with St. Peter, the Roman Papacy, and the wider Roman-Ruthenian inheritance.
The Roman-Ruthenian Papacy brings these inheritances into a single sacred trust: office, responsibility, jurisdiction, patrimony, and inherited authority lived in the present.
