The Holy New Martyr John Kalphes (the Apprentice) lived in a suburb of Constantinople, called Galata. He was a cabinetmaker by profession, and he had acquired great skill in his craft, so that important officials made use of his services. He was entrusted with the inner adornment of the sultan’s palace.
St John Kalphes was distinguished for his Christian charity, he provided for orphans and those locked up in prison, and many turned to him for help. One time a certain dignitary asked St John to take on his nephew as an apprentice. He agreed, and the youth received an honorable position at court upon the completion of his apprenticeship.
Once, encountering his former teacher and benefactor, he asked St John what it says in the Christian books about their “prophet” Mohammed. St John did not want to answer his question, but because of the persistent demands of the youth, he declared that Mohammed was a mere mortal, an uneducated man who did not perform a single miracle during his lifetime. He went on to say that Mohammed was no prophet, but rather an adversary of God. The youth, devoted to Islam, reported to his fellow Moslems that the cabinetmaker had insulted Mohammed.
St John was brought to trial, where they demanded that he renounce Christ, but he bravely confessed his faith in Christ. After torture, they sent the holy martyr off to penal servitude, where he spent six months. Then, for the next three months they beat him in the prison. Seeing that they could not coerce him into submitting to their will, they beheaded him in the crowded city square in Ergat-Bazara, near the Bedestan (a covered bazaar) on February 26, 1575.
The suffering of the holy Martyr John Kalphes were recorded by Father Andrew, the Chief Steward (Megas Oikonomos) of the Patriarch of Constantinople, who communed him with the Holy Mysteries in prison.
