The righteous Evdokim, a native of Cappadocia (Asia Minor), lived in the 9th century during the reign of Emperor Theophilus (829-842). He was the son of the pious Christians Basil and Evdokia, noble by birth and known to the emperor. The righteous life of Saint Evdokim was entirely aimed at pleasing God and helping others. Having taken a vow of celibacy and chastity, he avoided talking to women and did not look at them; only with his mother, whom he deeply revered, he had soul-beneficial conversations. For his virtuous life, the emperor appointed Saint Evdokim as the ruler of the Kharsian region. 
Fulfilling his duties as God's servant, the righteous Evdokim governed people and judged them justly and with meekness, took care of the poor, orphans and widows, and was a defender of the wronged. His personal Christian exploits, which he carried out in secret, were known only to God.
Evdokim pleased God with his blameless life, and the Lord called him at the age of 33. Lying on his deathbed, Saint Evdokim bequeathed to put himself in the coffin in the clothes in which his death would find him. Then he sent everyone out of the room and prayed to the Lord that no one would see his death, just as no one had seen his secret exploits during his lifetime. His family buried him, as he had bequeathed to them. Immediately after the death of the righteous Evdokim, miracles began to be performed from his tomb, many sick people were healed, and the fame of miraculous healings grew.
18 months later, the mother of Saint Evdokim came from Constantinople, where his parents had moved after the saint's death, to venerate the relics. She ordered the stone to be removed, the earth to be dug up, and the coffin to be opened, and everyone saw the saint's face, bright as life, untouched by corruption. A great fragrance emanated from him. The coffin with the relics was carried up from the ground. The saint was dressed in new clothes. The mother wanted to take her son's relics to Constantinople, but the Harsian residents did not allow them to take away the shrine that was dear to them. However, after some time, Hieromonk Joseph, who lived and served at the tomb of the saint, nevertheless took the relics of Saint Evdokim to Constantinople. There they were laid in a silver shrine in the church of the Blessed Virgin Mary, built by the righteous man's parents.
