Birth and Upbringing at Shio-Mgvime
The Narration of Saint Shio's Miracles, attributed to Catholicos Basil III, relates that the hitherto childless parents of John prayed at length to Saint Shio of Mgvime for a son, and following his birth sent him to be raised at the Shio-Mgvime Monastery.
Shio-Mgvime is a medieval Georgian monastic complex near Mtskheta, roughly 30 km from Tbilisi, founded by the 6th-century monk Shio, one of the Thirteen Assyrian Fathers who came to Georgia as Christian missionaries. By the end of the 6th century it is said to have housed some 2,000 monks, and it remained under the patronage of the Catholicos of Georgia throughout the medieval period.
It was in this setting that John acquired the wisdom and eloquence reflected in his epithet 'Chrysostom.'
