Ministry and Martyrdom
The synaxarion records that John, as bishop, and James, as presbyter, taught the words of faith to the pious and converted many unbelievers. Their success in attracting converts led to their arrest by the king.
Both men were subjected to various tortures designed to force them to abandon Christianity and accept Zoroastrianism. When they refused, they were executed; the synaxarion states that their heads were cut off by the sword. They are remembered in Orthodox tradition as having received the crowns of martyrdom.
