The Holy Apostolic See of Sts. Peter, Andrew, Stephen, and Mark

The Roman-Ruthenian Church and State is the rightful temporal successor of St. Peter, carrying the historical and documented patrimony of Rome and Russia through St. Leo X, with full Orthodox and Catholic autocephalous authority—equal to the Vatican, Constantinople, and other Patriarchates.

The Holy Apostolic See is the true visible Orthodox head of all Latin Christians, in addition to all others under her sacred mantle of care. The Church serves as the Orthodox Old Catholic jurisdiction for the historic lands of the Western Patriarchate and Holy Rus’. We are the Eastern Roman Church with Latin heritage, where East and West meet.

The United Roman-Ruthenian Church is a contemporary expression of an ancient Apostolic inheritance. Its official timeline begins with the founding of the Church in AD 33, and its authority derives from preserved Apostolic succession received through Rome, Constantinople, Antioch, Jerusalem, and their historic extensions into Rus’ and the Americas.

The URRC is a derivative patriarchate formed by the convergence of these ancient lines, united by continuity of faith, order, and sacramental life. Its constituent jurisdictions merged in 2023 to form the modern United Roman-Ruthenian Church.

The Holy Apostolic See is under the patronage of Saints Peter, Andrew, Stephen, and Mark, reflecting both its Eastern and Western inheritance. Through Apostolic succession, ecclesial grants, and formal recognitions, the Church inherited not only orders but jurisdiction, autocephaly, and custodial responsibility for the Petrine inheritance within the Latin Orthodox tradition.

Continuity and unity

The Custodian of Apostolic Continuity and Orthodox-Catholic Unity

The United Roman-Ruthenian Church and Pontifical Imperial State is a sovereign, autocephalous patriarchal Church rooted in both Orthodox and Catholic tradition. Emerging as a derivative patriarchate of Rome, Russia, Greece, and America, it is an Eastern Roman Church with Latin heritage.

Declared by ecclesiastical decree and divine providence, the Roman-Ruthenian Pope Radislav I, was quietly confirmed in 2014 as coadjutor to the Roman Pope by the Cardinal Dean, entrusted with full papal authority in the jurisdiction of the United Roman-Ruthenian Church. The results began to be revealed publicly in 2020.

That confirmation was brought to full completion following the death of Pope Francis on 21 April 2025, the traditional founding date of Rome and the day on which Radislav had been sacramentally confirmed into the Roman Church decades earlier. The convergence is a divinely providential realignment.

The Roman-Ruthenian Church is the guardian of Latin Orthodoxy, the bridge between East and West, and the visible head of the Latin tradition in fidelity to the Orthodox and Catholic faith.

A Church, a State, a People

The Pontifical Imperial State of Rome-Ruthenia, a non-territorial ethno-religious nation without border, complements the Church’s mission. It preserves the cultural, legal, and spiritual heritage of the Roman Empire, the Holy Roman Empire, Old Rus’, and the Holy Apostolic See.

The Church’s mission is custodial, protecting the undivided Church’s theological, liturgical, and cultural legacy. It embraces conciliar Orthodox Christianity, integrating East and West without compromise or syncretism.

The Church offers itself as a sanctuary of continuity for those dislocated by theological rupture, ecclesiastical scandal, or spiritual displacement.

Apostolic inheritance

Immediate Patriarchal Ancestors

The Church is a derivative patriarchate of these Russian, Syrian, Greek, and American patriarchates, as well as Rome as rightful temporal successor of St. Peter. St. Aftimios is one of the two Holy Fathers of the Holy Apostolic See.
