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. The Church
stands not only as a symbol of ecclesial unity but as the rightful
temporal successor to St. Peter and spiritual successor to Pope St. Leo
X.
Declared by ecclesiastical decree and divine providence, the
Roman-Ruthenian Pope-Catholicos,
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 of this act slowly began to be
revealed to the public 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 very day on which Radislav had
been sacramentally confirmed into the Roman Church decades earlier. The
convergence of these dates is not coincidence, but
a divinely
providential realignment.

The Roman-Ruthenian Church affirms itself as 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. It 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 United
Roman-Ruthenian 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 of Saints
Peter,
Andrew, Stephen, and Mark.
The Church’s mission does not seek civil rule. It is neither
territorial nor expansionist, but custodial, protecting the
undivided Church’s theological, liturgical, and cultural legacy. It
embraces the harmony of conciliar Orthodox Christianity, integrating
East and West without compromise or syncretism. From its Byzantine
rites and Syriac influences to its Latin liturgy and apostolic
governance, it serves as a living witness to the pre-Schism Church.
Indeed, the United Roman-Ruthenian Church does not oppose the existence
of other
churches, nor seek to dominate their structures. Rather, it offers
itself as a sanctuary of continuity for those dislocated by theological
rupture, ecclesiastical scandal, or spiritual displacement. In doing
so, it fulfills not a partisan ambition, but a providential necessity.
A Voice for the Faithful
To the disillusioned, the traditional, and the faithful, clergy and
laity alike, the United Roman-Ruthenian Church offers this message: the
Apostolic Church is not lost. The truth endures.
As Radislav I of Rome-Ruthenia declares:
“We
do not claim perfection. We claim only what was given to us: the
keys, the cross, and the promise that the gates of hell shall not
prevail.”
