Historical Context
The see of Kiev had been left vacant after the death of Metropolitan Michael in 1145. Grand Prince Isiaslav then appointed the schemamonk Clement (Clement Smolyatich) as metropolitan without the approval of the Patriarch of Constantinople, an irregular act that broke with established Russian Church tradition.
Archbishop Nifont of Novgorod criticized this appointment as contrary to canonical order. In response, the Patriarch of Constantinople sent Constantine to investigate the situation in Kiev and to restore proper governance to the metropolitan see.
Ministry and Controversy
Upon his arrival, Constantine removed Clement from office and exiled all the priests whom Clement had ordained. Though intended to restore canonical order, these measures created significant ecclesiastical division and popular discontent.
The dispute proved difficult to settle. The Patriarch eventually sent a third metropolitan, Theodore, to resolve the matter by deposing both Constantine and Clement, ending the contested succession.
Death and Vindication
Constantine died in 1159. In his will he expressed deep remorse for having sown discord in the Church and, judging himself unworthy of burial, requested that his body be cast out into a field rather than interred. Despite their reluctance, the officials honored this request.
According to the account, three days of severe storms followed his death, with thunder, lightning, and earthquakes over Kiev; the tradition relates that eight men perished from the thunder and that three fiery pillars appeared over Constantine's body.
Witnessing these signs, the Prince of Kiev ordered Constantine's remains placed in the church where Prince Igor had been buried. After his honorable reburial, calm returned to the region, which the tradition understood as God's vindication of His humble servant.
Commemoration
The OCA calendar for June 5 lists Blessed Constantine, Metropolitan of Kiev, among the commemorations of the day. He is remembered alongside the Hieromartyr Dorotheus of Tyre, the Translation of the Relics of the Right-believing Igor-George, Grand Prince of Chernigov and Kiev, and the Repose of Saint Theodore Yaroslavich.
The connection with Prince Igor is especially close, since Constantine's remains were laid in the church associated with Igor's tomb.
