One of the most stirring martyrdoms recorded in church history is Polycarp's. When the venerable bishop of Smyrna (modern-day Izmir, in Turkey) heard the Romans were planning to arrest him, he heeded his friends' advice and withdrew to a small estate outside of town. But while in prayer there, he had a vision. "I must be burned alive," he told his friends. When the soldiers arrived, his friends once more urged him to run, but Polycarp answered, "God's will be done."

After being escorted to the proconsul, Polycarp carried on a witty dialogue with his questioner, who flew into a rage and threatened Polycarp with death by fire. "The fire you threaten burns but an hour and is quenched after a little," Polycarp answered; "for you do not know the fire of coming judgment, and everlasting punishment, that is laid up for the impious. But why do you delay? Come, do what you will."

At the execution scene the soldiers began to secure him to the stake, but Polycarp stopped them: "Leave me as I am. For he who grants me to endure the fire will enable me also to remain on the pyre unmoved, without the security you desire from nails." He prayed and the fire was lit. The second-century chronicler of this martyrdom said it was "not as burning flesh but as bread baking or as gold and silver refined in a furnace." The martyrdom, he added, was remembered by "everyone"—"he is even spoken of by the heathen in every place."

Calm demeanor. Courageous words. A death noted by unbelievers. One can't help admiring this type of martyrdom and feeling ennobled and encouraged by it. Unfortunately, not all martyr stories are so inspiring.
