Saint Agapitos came from Cappadocia and was the son of pious and God-loving parents. He lived during the time of the emperors Diocletian (284-305) and Maximian (285-305). At a young age he departed for a monastery near Synnada in Phrygia, where he became a monk. He was loved by the Igumen because of his virtuous life and so he was taught how to read and write. He also received from God the gift of working miracles, performing over a hundred of them. By his prayers he killed a great dragon, which had appeared near the monastery, carrying off both people and animals. This was a great benefit for those who had turned to him for help.
Later on, during the reign of Licinius (308-323) Saint Agapitos was recruited into the army against his will. There he saw the victorious Martyrs Victor, Dorotheos, Theodoulos, Agrippa and many others, being tortured for their faith in Christ. Right away he wanted to join them in their martyrdom. Though they were perfected in Christ by the sword, he was preserved and, by God's providence, he suffered no harm, even though they wounded him with a spear. His life was spared so that he might lead many to salvation.
The holy Emperor Constantine the Great (May 21) heard that Saint Agapitos could heal people by his prayers. The emperor sent him a sick servant, and he was cured. Saint Constantine wished to reward Saint Agapitos, but he asked only that he be discharged from military service and be permitted to return to his monastery. His request was granted, and so he went back to the monastery.
Saint Agapitos devoted himself to the study of the Holy Gospel, and the Bishop of Synnada ordained him to the holy priesthood. After the bishop reposed, Saint Agapitos was chosen to succeed him in this position by the common consent of the clergy and the people.
After governing his flock in a God-pleasing manner, instructing them in the Orthodox Faith, and in virtuous living, Saint Agapitos reposed in peace
