Captivity and Confession
The events of John's life belong to the period of Tatar raids on the Russian lands before the fall of the Khanate of Kazan. Inhabitants of Nizhni Novgorod were carried into captivity and distributed among masters in Kazan, and John fell to the household of Alei-Shnur, who was related to the Khan. The synaxarion presents him as a diligent and faithful servant whose nights were given over to prayer.
The decisive moment of his life was his refusal to convert to Islam. According to the tradition, he openly declared himself a Christian and would not renounce Christ under any pressure or torture, which provoked his master to order his death.
