Early Life and Monastic Beginnings
Cornelius descended from the Kriukov boyar family. His brother Lukian served at the court of the Great Prince of Moscow. When Lukian resolved to enter monastic life at the monastery of Saint Cyril of White Lake, Cornelius—who had longed for the solitary life from a young age—followed him.
After his tonsure, Cornelius took up demanding duties, wearing heavy chains while laboring in the bakery and copying church books in his free time. Seeking greater solitude, he left White Lake and traveled through various places, including Rostov, Novgorod, and the Sabbatiev wilderness monastery in the Tver region, before settling permanently.
Foundation of the Komel Monastery
In 1497, Cornelius settled in the Komel forest, not far from Vologda, where he built a cell. Monks gradually gathered around his dwelling. In 1501 he constructed a wooden church in honor of the Entry into the Temple of the Most Holy Theotokos, and in that year Metropolitan Simon ordained him hieromonk.
By 1512, as the number of monks increased, he built a stone church and compiled a Rule for the brethren based on the Rules of Saints Joseph of Volokolamsk and Nilus of Sora. This was the third monastic Rule written by Russian saints. During a famine he built an orphanage in the monastery courtyard. According to his Life, he received visions of Saint Anthony the Great and constructed a church in his honor.
Departure, Return, and Repose
Some of the monks complained of Cornelius's strictness, and he was compelled to leave the monastery for a time. The Great Prince Basil Ivanovich persuaded him to return. Upon his reinstatement, Cornelius transferred the guidance of the community to his disciple Laurence and enclosed himself in his cell.
Cornelius died at the age of eighty-two on May 19, 1537. His commemoration was formally established on January 25, 1600, by Patriarch Job together with a council of bishops. The Life of the saint was written by his disciple Nathaniel in 1589.
Disciples and Legacy
Cornelius was the teacher of many monastics who themselves became founders and leaders of northern Russian monasteries. Among his disciples are numbered Saints Gennadius of Liubimograd (January 23), Cyril of New Lake (February 4), Herodion of Iloezersk (September 28), Adrian of Poshekhonye (March 5), and Laurence and Cassian of Komel (May 16).
Saint Cassian served as a disciple under Cornelius. When Cornelius departed to Lake Sura, the brethren chose Cassian as abbot with Cornelius's blessing; Cassian strove to imitate his teacher in everything and strictly observed his Rule, grounding his instruction in prayer, the fear of God, sobriety of thought, vigilance, and contrition. Upon Cornelius's return, Cassian willingly stepped down, preferring to remain in obedience to the Elder. He died in 1537, the same year as Cornelius.
Saint Laurence was likewise a disciple of Cornelius. On Cornelius's recommendation, the community unanimously chose Laurence as igumen in 1538, the year after Cornelius's death. Laurence continued to apply his teacher's spiritual counsels and administered the Korniliev monastery for about ten years. Under his leadership, Elder Alexius placed the Koptevo monastery under Korniliev's authority in 1547. When Tatars approached, Laurence followed Cornelius's earlier advice and led the monks to safety, returning once the danger had passed. He maintained his beloved work of copying books and died on May 16, 1548.
