One of the Thirteen Syrian Fathers (ათცამმეტი ასურელი მამანი, atsamet’i asureli mamani), Saint Shio established one of the largest monastic centres in central Georgia, the Shio Mgvime Monastery in Mtskheta, around 30 km from Tbilisi. The monastery is located in a steep gorge outside the town. Many of the structures date to the late 6th century and are still in use as a functioning monastery.
From ” Lives of the Georgian Saints” by Archpriest Zacharaiah Machitadze, Saint Herman of Alaska Press
“The Monk Shio (Simeon) of Mgvim was born in Syrian Antioch. His parents were Christians and raised their son as the only heir. The youth received a fine education, he studied the Holy Scripture and already in his early years he became accomplished in the ability of expounding the Word of God. Having learnt about an holy ascetic named John, Shio secretly left his parental home and set out to the saint. The Monk John made the youth return to his parents, after foretelling that his parents would become monastics. The prediction was soon fulfilled: Shio distributed his inheritance and accepted tonsure from the Monk John.
The Monk Shio 20 years later, amidst 12 other chosen disciples of Saint John, set off to Iveria (the eastern half of Georgia) to preach the Word of God. With the blessing both of his teacher and of the Georgian Catholicos Eulabios, the Monk Shio settled into a cave west of the city of Mtskheta, where he made austere ascetic efforts and was vouchsafed miraculous visions. The solitary life of the ascetic became known of, and soon the place of the saint’s efforts was transformed into a monastery, at which a church in the Name of the Most Holy Trinity was established by the monk. Later on other churches were built: in honour of the Mother of God and John the Forerunner. All the churches were consecrated by the Catholicos Makarios. The number of brethren increased, and the monk gave his blessing for them to found the Mgvim monastery, while he himself continued his deeds of salvation in seclusion. The Monk Shio reposed on 9 May, having the evening before communed the Holy Mysteries and given the brethren a final salvific instruction. The remains of the Saint of God were buried in the monastery founded by him. The Monk Shio is known, as the author of 160 precepts for the brethren.”
This saint is commemorated on the Thursday of Cheesefare Week (the week before Great Lent) as a movable feast, and also is commemorated in May.
The monastery built upon the site of his original community includes many caves dug into the hillside. At one time if was the most populous monastery in the country with over 2000 monks in residence, with music, liturgical works and sacred literature composed here. The monastery has been attacked or the monks dispersed many times by Persians, Mongols and Turks, and was shut down by the Communists also. It is now once again a thriving monastic centre with many monks and pilgrims.
