4 The soldiers around, the clash of the arms wherewith the church is surrounded, do not alarm my faith, but they disquiet me from fear that in keeping me here you might meet with some danger to your lives. For I have learned by now not to be afraid, but I do begin to have more fear for you. Allow, I beg you, your bishop to meet his foes. We have an adversary who assails us, for our adversary “the devil goes about, as a roaring lion, seeking whom he may devour,” as the Apostle said. He has received, no doubt, he has received (we are not deceived, but warned of this) the power to tempt in this wise, lest I might perhaps by the wounds of my body be drawn away from the earnestness of my faith. You have read how the devil tempted holy Job in these many ways, and how at last he sought and obtained power to try his body, which he covered with sores.
