Confession and Martyrdom
According to his vita, when his former apprentice questioned him about Mohammed, John ultimately answered that Mohammed was a mere mortal and an uneducated man who performed no miracle in his lifetime, and was not a prophet but an adversary of God. The accounts relate his confession that Jesus Christ is the one and only true God, and his refusal to deny Christ when commanded to do so at trial.
His punishment was protracted. He was tortured, then sentenced to a term of penal servitude reported as six months, and afterward beaten in prison for three months. When it became clear that he would not be coerced into apostasy, he was beheaded in a crowded public square at Ergat-Bazara, near the Bedestan, on February 26, 1575, the date kept as his feast.
