Saint Joseph was a monk of Dionysiou Monastery on Mt. Athos, where he shone forth with the virtues of monastic life. He was an iconographer, and he painted the icon of the holy Archangels on the iconostasis of Dionysiou’s main church.
In obedience to the instructions of Igumen Stephen, St Joseph traveled to Constantinople with Eudocimus, who had apostasized from Orthodoxy to become a Moslem. Eudocimus repented, and wished to wipe out his sin through martyrdom.
When faced with torture and death, however, the unfortunate Eudocimus denied Christ again, blaming Joseph for turning him from Islam.
St Joseph was arrested and threatened with death. In spite of many tortures, he refused to convert to Islam. This holy martyr of Christ was hanged on February 17, 1819, and so he obtained an incorruptible crown of glory.
Some sources list his commemoration on February 17, while others list him on September 14 or October 26.
