Our Venerable Father Theodosius of Trnovo, the Bulgarian

Life

Saint Theodosius the Bulgarian was a fourteenth-century cleric and hermit of the Second Bulgarian Empire, a leading figure in the spread of hesychast monasticism among the Bulgarians. Born around 1300 near Trnovo, the Bulgarian capital, he became a disciple of Saint Gregory of Sinai, the influential hesychast master, and is credited with establishing hesychasm within the Second Bulgarian Empire.

He founded a monastery and monastic school at Kilifarevo, near Trnovo, which became a center of spiritual learning. A zealous defender of Orthodoxy, he took a prominent part in condemning heresies during the reign of Tsar Ivan Alexander of Bulgaria. Toward the end of his life he traveled to Constantinople, where he reposed at the Monastery of Saint Mamas; sources place his death in 1362 or on 27 November 1363.

He is commemorated together with his disciple Romanus, who succeeded him as abbot. Among his other disciples was the future Patriarch Euthymius (Evtimiy) of Trnovo, the last head of the medieval Bulgarian Orthodox Church.

Hesychasm in the Bulgarian Empire

Theodosius is credited with establishing hesychasm in the Second Bulgarian Empire. His teacher, Saint Gregory of Sinai, had arrived on Mount Athos in 1310 and remained until 1335, but increasing Muslim raids on Athos pushed Gregory and several disciples into the Bulgarian lands, where Emperor Ivan Alexander granted protection. Gregory founded a community near Paroria in the Strandzha Mountains and reposed there on 27 November 1346.

Through Gregory, Theodosius joined a circle of hesychast disciples that also included Patriarch Kallistos I of Constantinople, Nicodemus of Tismana, and Romylos of Vidin. The monastery and school Theodosius established at Kilifarevo carried this contemplative tradition into the heart of the Bulgarian capital region.

Defense of Orthodoxy and Legacy

Theodosius took an important part in condemning various heresies during the reign of Tsar Ivan Alexander, exercising theological authority within the medieval Bulgarian Orthodox Church.

His most consequential disciple was Euthymius (Evtimiy), who joined Kilifarevo around 1350 and was appointed Theodosius's first assistant in 1363. After Theodosius's death, Euthymius went on to the Studion Monastery and the Great Lavra on Mount Athos, and later became Patriarch of Trnovo — the last head of the medieval Bulgarian Orthodox Church. St. Theodosius Nunatak in Antarctica is named after him.

Commemoration

Theodosius is commemorated on February 17, and a feast of Saint Theodosius of Trnovo is also observed on November 27 — the date aligning with the reported year of his death. The two dates are understood to refer to the same Bulgarian hesychast.

He is commemorated together with his disciple Romanus, who succeeded him as abbot of his monastery. This Romanus is distinct from Romylos of Vidin, a fellow disciple of Gregory of Sinai who briefly bore the monastic name Romanos before changing it to Romylos.

Notes

Commemorated together with his disciple Romanus. Nov 27 = Theodosius of Trnovo (likely the same Bulgarian hesychast; verify).
