The Monk Procopius was born in the Decapolitan country (i.e., Decapolis), east of the Lake of Galilee. Having left the hectic world, Prokopy took monastic orders in one monastery and spent all his time in prayer and fasting. Experienced in monastic feats, adorned with purity of soul, he was glorious and famous among ascetics. Meanwhile, around this time, the iconoclastic heresy appeared. She was aroused by the impious emperor Leo the Isaurian, who considered icons to be idols, and those who worshipped them to be idolaters.
St. Procopius, along with other zealots of Orthodoxy, rebelled against the impious heresy of the iconoclasts; he exposed the insane wisdom of the heretics and defeated them with invincible divine words. This brought upon him the wrath and displeasure of the emperor. By his command, St. Procopius was captured and subjected to severe tortures: he was inhumanly beaten, his body was whittled with iron tools and then thrown into a stinking dungeon. In this gloomy dungeon, the Rev. Prokopius, along with Saint Basil, his companion in monastic life, suffered until the death of Emperor Leo the Isaurian. When Leo died, Procopius, along with Basil and other holy martyrs, was released from prison. The Monk Prokopius the Decapolite spent the end of his life peacefully in monastic labors.
At a very old age, he passed into another life in order to see Christ no longer on the icons that he had defended all his life, but face to face, and to receive from Him a great reward in heaven for his labors and sufferings.
