Pap The Apostolic Puzzle: Illyricum Sacrum and the Origins of Christianity in the Ancient Roman Province

The work Illyricum Sacrum is examined in this article or more specifically, how it presents the origins of Christianity in the ancient Roman province. The claims made by the editors of the Illyricum Sacrum are analysed in regard to the apostolic origins of the churches in the area, focusing on the roles of apostles Peter and Paul, as well as their disciples Titus and Domnius in particular. The article discusses the absence of concrete evidence supporting these claims and explores the potential religious and political motivations behind the narrative. It also takes the Jesuits' influence into account in proving these churches' antiquity and apostolicity. Despite possible deficiencies, the article1 recognizes the value of Illyricum Sacrum as a historical source for researching Christianity in the Adriatic region.
