Name and Identity
John the Faster of the Kiev Near Caves should not be confused with John the Faster, Patriarch of Constantinople, an entirely distinct saint. Within the Kiev Caves community there are also other monks who bear the same epithet of fasting, so that the designation "of the Near Caves" together with the December 7 commemoration serves to identify him.
The epithet "the Faster" reflects the ascetic practice that the tradition holds to have defined his life. A liturgical text applied to him describes a monk who was illumined by fasting and who consumed the word of God more than food.
