Martyrdom of Polycarp 4:1

Now one named Quintus, a Phrygian, who was but lately come from Phrygia, when he saw the wild beasts, became afraid. This was the man who forced himself and some others to come forward voluntarily [for trial]. Him the proconsul, after many entreaties, persuaded to swear and to offer sacrifice. Wherefore, brethren, we do not commend those who give themselves up [to suffering], seeing the gospel does not teach so to do.
