The theological and literary heritage of Leontius of Byzantium, the famous theologian and polemicist of the VI century, still remains insufficiently studied in Russia, while in the West in the XIX-XX centuries. Dozens of studies have been conducted[edit] The modern Russian reader knows, perhaps, only brief references to Leontia in the works of Archpriest George Florovsky and Protopresbyter John Meyendorff .. There is still no complete Russian translation of a single treatise by Leontius of Byzantium .... Without claiming completeness and finality, the proposed collection of studies is now intended to give the modern Russian reader the necessary information about the composition of the “Corpus Leontianum” (Corpus Leontianum), its alleged authorship, structure and content of the theological works included in it. *** Editorial Board of the Center for Biblical and Patrological Research (program of support for young scientists of the VPMS) of the Department for Youth Affairs of the Russian Orthodox Church : Serhii Shastin (Abbot of Krutitsky Patriarchal Podvorye , Chairman of the All-Russian Orthodox Youth Movement and the Brotherhood of Orthodox Investigators , Deacon Mikhail Pershin (director of the center , Head of the Information and Publishing Sector of the Department for Youth Affairs of the Russian Orthodox Church , Serhii Osipov (technical editor) , Prof. D.
