Early Life and Calling
Sergius was born Bartholomew into a boyar family near Rostov. According to his hagiography, the young Bartholomew struggled to learn to read until a spiritual elder appeared to him in a field and blessed him with holy bread; afterward he was able to read fluently, and from childhood he was devoted to prayer and fasting. The vita also relates that miraculous signs accompanied his mother's pregnancy.
After his parents' deaths he joined his brother Stephen in monastic life at Khotkovo. The two then withdrew to the forest and established a hermitage dedicated to the Holy Trinity, situated by tradition about twelve versts from Radonezh on Makovets Hill. When Stephen departed, Sergius remained alone for a period before disciples gathered around him.
Monastic Founder and Reformer
Made igumen in 1354, Sergius introduced a strict communal, cenobitic discipline into the community, which became the spiritual center that grew into the Holy Trinity–St. Sergius Lavra near Moscow, today the most venerated monastic house in Russia. The Patriarch of Constantinople sent charters confirming his rules.
Sergius also founded a monastery on the River Kirzhach dedicated to the Annunciation. His disciples established a large number of monasteries across central and northern Russia — commonly reckoned at about forty, though some accounts give a far higher figure — including houses connected with Borisoglebsky, Ferapontov, Kirillo-Belozersky, and Vysotsky, as well as the Andronikov and Simonov monasteries in Moscow.
Known for his humility, Sergius declined high honors. Metropolitan Alexius asked him to succeed as bishop, an offer Sergius refused, and he likewise declined a gold cross and the office of metropolitan.
National Role and Legacy
Before the 1380 Battle of Kulikovo, Grand Prince Dmitry Donskoy sought Sergius's blessing. Sergius sent with him two warrior-monks, Alexander Peresvet and Rodion Oslyabya, and foretold the prince's victory, an episode that linked his memory to the rise of Moscow and the resistance to Mongol domination.
The historian Serge Zenkovsky noted that Sergius, together with Epiphanius the Wise, Stephen of Perm, and the iconographer Andrei Rublev, signified the Russian spiritual and cultural revival of the late fourteenth and early fifteenth centuries. His life was recorded by the hagiographer Pachomius the Serb in a fifteenth-century manuscript.
Relics & Shrines
Sergius's relics, found incorrupt, were discovered in 1422 and placed in the new Trinity Cathedral at the monastery he founded. During the Soviet period the relics were hidden; the theologian Pavel Florensky is reported to have died in the Gulag, possibly after refusing to disclose their location. The relics were returned to the Troitse-Sergiyeva Lavra cathedral in 1946 when it reopened.
Veneration
Sergius is venerated in the Eastern Orthodox Church and is also commemorated in the Catholic Church and the Anglican Communion. His feast days are September 25, marking his repose, and July 5, marking the translation (discovery) of his relics.
