Episcopal Ministry
Ignatius began as a cleric in Rostov before entering the Theophany Monastery, where he became archimandrite in 1261. The following year, on 19 September 1262, Metropolitan Cyril III of Kiev appointed him Bishop of Rostov, an office he held for twenty-six years.
The chronicles record his presence at princely marriages and burials across the years 1266, 1269, 1271, and 1276 to 1278, and his attendance at the 1274 synod held at the Vladimir Cathedral. He is also remembered for contributing to Christian outreach in the Beloozersk region, for reconciling the princes Demetrius and Constantine Borisovich in 1281, and for traveling to the Mongol horde in 1282 to advocate for the clergy.
