The Holy Apostolic See of Saints Peter, Andrew, Stephen, and Mark is the full central apostolic see of the United Roman-Ruthenian Church. Its dedication expresses the Church’s Roman, Eastern, Stephenian, and Aquileian inheritance.
Patronal meaning
Saint Peter signifies the Church of Rome and its Petrine inheritance; Saint Andrew the First-Called signifies the apostolic heritage of the Christian East and Rus’; Saint Stephen the Deacon and Protomartyr is associated with the modern institutional succession of the Diocese of Rome-Ruthenia; and Saint Mark the Evangelist represents the Aquileian and wider apostolic patrimony received by the Church. Together the Diocese of Rome-Ruthenia and the Metropolitan See of Aquileia form the central jurisdictional nucleus of the Catholicate of Rome-Ruthenia, the Roman-Ruthenian Pope's patriarchal jurisdiction, as well as for the United Roman-Ruthenian Church as a whole.
Development
The Church’s historical account records the Apostolic See of Saints Stephen and Mark as a stage in its modern development. Following the union of its constituent jurisdictions and the fuller manifestation of its apostolic patrimony, the central see was consecrated under its present four-saint dedication in 2025.
