Joannicius Troitsky

Holy Venerable Joannicius Troitsky, called also Joannicius of Radonezh, is numbered by the later tradition of saints' lives among the disciples of the founder of the Holy Trinity monastery on Mount Makovets. Among the closest disciples of Saint Sergius he is named in a stichera of the service of Venerable Michaias of Radonezh: "Rejoice, glorious monastery of Sergius, making the memory of his disciples: of Elijah the most wonderful, of Joannicius, of Simon the sacristan."

Venerable Joannicius is painted on the icon "Saint Sergius of Radonezh with his disciples in prayer to the Holy Trinity", made at the end of the seventeenth century in the workshop of the monastery, which shows his local veneration in the monastery. It is thought that he was one of the first monks who died at the Holy Trinity monastery. Probably he was tonsured with the name of Venerable Joannicius the Great, who composed a prayer to the Most Holy Trinity. His full-⁠length image is painted together with that of Venerable Elisha of Radonezh on a window reveal of the north wall of the refectory part of the church of Saint Sergius (1883, repainted in the twentieth century).

The memory of Venerable Joannicius of Radonezh is kept on 17 November. The Church commemorates him also on 19 July, in the new style, in the Synaxis of the Saints of Radonezh, and on the movable day of the Synaxis of the Saints of Moscow (5 September).
