Saint Mercurius Bishop of Smolensk

Life and Ministry

According to the Orthodox Church in America's synaxarion, Mercurius lived as an ascetic in the Far Caves of Saint Theodosios, where he enlightened his soul through unceasing prayer and rigorous fasting and was held to have become a vessel of the Holy Spirit. From this monastic life he was called to the see of Smolensk, where the tradition holds that he succeeded Bishop Lazarus as head of the diocese.

His episcopate fell during the years of the Tatar invasions of the region. The synaxarion relates that he served his flock through the horrors of the assault on Smolensk associated with the campaigns of Batu Khan. The OCA troparion remembers that he glorified God by his words and his actions while on earth and that he continues this glorification before the heavenly Throne.

Sources differ on his precise dating. The OCA places him in the fourteenth century, while the account preserved by Mystagogy (Sanidopoulos) sets his asceticism in the thirteenth century and dates his death to 1239, during Batu Khan's invasion; that account locates his ascetic struggle in the Near Caves of the Lavra rather than the Far Caves. The fourteenth-century dating is followed here.

Relics & Shrines

By tradition, before his death Mercurius asked that his coffin be placed upon the Dnieper River and allowed to be carried wherever it might come to rest. The synaxarion relates that his remains arrived miraculously at the Kiev Caves Monastery, where they were interred. The OCA account places his relics in the Near Caves of Saint Anthony.

He is said to have shared a deep spiritual bond with Saint Paisios of the Far Caves, with whom he was originally buried; their relics are now kept in separate reliquaries. According to the Mystagogy account, a holy mantle hangs over his tombstone.

Distinct from the Martyr Mercurius of Smolensk

The anchor record notes that this saint is distinct from the Holy Martyr Mercurius of Smolensk, who is commemorated on the same day. The martyr was, by tradition, a soldier of a noble Orthodox family serving the Prince of Smolensk during the Mongol invasion of 1238. The synaxarion relates that, directed by a voice from the Smolensk Icon of the Mother of God, he went to Dolgomoste to engage the Tatar forces and was slain in battle, after which the enemy withdrew; his body was buried in the Cathedral of the Dormition.

The OCA calendar for August 7 lists the two Mercurius entries separately, confirming that the venerable bishop and the martyred soldier are different saints who share the feast.
