Cyriacus was born in Corinth, to John and Eudoxia. His father John was a presbyter and Peter, Bishop of Corinth, was his kinsman. In his early youth, the bishop ordained Cyriacus a reader in the cathedral church. Reading the Holy Scripture, the young Cyriacus marvelled at God’s providence: how God glorified all His true servants and how he arranged the salvation of the human race. At age eighteen, Cyriacus’s desire for the spiritual life led him to Jerusalem. There, he entered the monastery of a godly man Eustorgius, who gave him his first instruction in the monastic life. After that, he went to St. Euthymius, who foresaw that he would be a great spiritual father. He clothed him in the schema and sent him to St. Gerasimus at the Jordan, where Cyriacus spent nine years. Following the death of Gerasimus, he returned to the Monastery of St. Euthymius, where he remained in stillness for ten years. Then, fleeing the praise of men, he moved from place to place. He finally lived a life of asceticism in the community of St. Chariton, where he ended his earthly sojourn of 109 years. A celebrated ascetic and miracle-worker, St. Cyriacus was massive and strong in body, and remained such in deep old age, despite strict fasts and vigils. In the wilderness, he sometimes ate only raw greens for years. He was very zealous for the Orthodox Faith, denouncing all heresies, especially that of Origen. He said of himself that, since he became a monk, the sun had neither seen him eat nor become angry with anyone. According to the Rule of St. Chariton, the monks ate only once a day, after the setting of the sun. Cyriacus was a great light, a pillar of Orthodoxy, the adornment of monks, a mighty healer of the sick, and a gentle comforter of the sorrowful. Having lived long for the benefit of many, he took up his habitation in the eternal joy of his Lord in the year 557.

The sacred lavra doth at all times rightly honour thee as a sure helper and support and mighty champion, and it annually observeth thy holy mem’ry. And since thou, O righteous Cyriacus, dost possess boldness with the Lord, protect us from our enemies, that we may cry to thee: Rejoice, O thrice-blessed Father.
