The righteous Evdokim was from Cappadocia, the son of pious parents. During the reign of Theophilus, he served in the army, distinguished by a virtuous life, observing God's commandments, fasting, and prayer. He showed charity to the poor and benefacted the churches, maintaining virgin purity. For his virtues, he was loved and respected, became the commander of the Cappadocian regiment, and governed with kindness and justice. He died at the age of 33, pleasing God, and his death was a mystery, as was his life. After his death, his relics became a source of miracles, healing the sick. His mother, learning about the miracles, came to his grave and, seeing the incorrupt body, glorified God. The townspeople did not allow her to take the relics, asserting that they were needed for healings in their land. Later, the monk Joseph secretly transferred the relics to Byzantium, where they continued to work miracles. The parents rejoiced at the return of the relics, which were placed in the church of the Most Holy Theotokos, praising God for the miracles of the saint.
