The saint fasted on weekdays, eating only on Saturdays and Sundays, and his only food was the Eucharist. During the day he fulfilled his monastic obediences, and at night he kept vigil.
St Gelasius was the spiritual Father of many hermits of Rimet Mountain, whom he would visit during Great Lent. He healed the sick, and cast out demons from those who were possessed. It is said that a spring of water appeared through his holy prayers.
His later years were spent as a bishop, and he departed to the Lord after many labors on behalf of his flock.
St Gelasius was glorified by the Orthodox Church of Romania in 1992.
