The holy monastic martyr Deacon James was a disciple of Saint James of Kastoria of Prodromou Monastery on Mt. Athos.
The Turkish authorities in Aetolia, fabricated false charges against Saint James of Kastoria that he intended to foment rebellion. In this manner, they attempted to force the saint into renouncing Orthodoxy. But Saint James and both his disciples, Deacon James and Saint Dionysius, endured the fiercest of torments over a period of many days. They suffered martyrdom on November 1, 1520.
The relics of the Monkmartyrs, glorified by miraculous healings, were placed in the monastery of Saint Anastasia, Deliverer from Potions in the small town of Galatista, near Thessalonica. In a short time, the fame of the holy relics attracted about 100 brethren to the monastery under Saint Theonas (April 4), who himself was a disciple of Saint James.
