December 4
John was first the chief minister to Caliph Abdul-Malik and later a monk in the Monastery of St. Sava the Sanctified. Because of his ardent defense of the veneration of icons during the reign of the iconoclastic Emperor Leo the Isaurian, John was maligned by the emperor to the Caliph, who cut off his right hand. John fell down in prayer before the icon of the Most-holy Theotokos, and his hand was rejoined and miraculously healed. Seeing this miracle the Caliph repented, but John no longer desired to remain with him as a nobleman. Instead, he withdrew to a monastery, where, from the beginning, he was a model to the monks in humility, obedience and all the prescribed rules of monastic asceticism. John composed the Funeral Hymns and compiled the Octoechos (The Book of Eight Tones), the Irmologion, the Menologion and the Paschal Canon, and he wrote many theological works of inspiration and profundity. A great monk, hymnographer, theologian and soldier for the truth of Christ, St. John is numbered among the great Fathers of the Church. He entered peacefully into rest in about the year 776 at the age of 104.

Come, O ye faithful, let us praise the hymn-writer, the Church’s luminary and wise instructor, the hallowed John, who cast down all her enemies; for since he took up the Cross of the Lord as a weapon, he drave off the heresies, with their every delusion. And as our fervent champion with God, he granteth all the forgiveness of trespasses.
