Composing the first Ukrainian Synaxarion (Chetii-Minei), the great Ukrainian theologian, scholar and hagiographer St. Dymytriy Tuptalo (1651–1709) relied on different sources, including Slavonic, Greek, Latin, and Polish. Thanks to an Antiochian Patericon by the Greek Syrian author Theodoret of Cyrrhus – History of the Friends of God, Dymytriy could introduce Theodoret’s holy friends to a Ukrainian readership, creating a bridge between the School of Antioch and Kyivan theological tradition. Introducing the Vitae of Syriac Saints into the Ukrainian and Russian Church calendar, Dymytriy to a considerable extent adopted Theodoret’s views on asceticism, Christian anthropology, and Church history. Thus, he may be called an ally of the Antiochian school, which was to a great extent marginalized in Byzantium since the 5th century and later on. Moreover, St. Dymytriy venerated Theodoret himself as one of those Saints despite incessant debates around his name initiated by his opponents at the Second Council of Constantinople.
