How St. Kevin of Glendalough [ca. 498-618] did battle with demons, and by the Mercy of God, Saved the Soul of an Undeserving Man, by God’s Grace
A certain cruel soldier had frequently perpetrated robberies among those mountain ridges. He had never done a good action but one, which was praying each day, that through St. Kevin’s merits, his soul might be saved. On a particular occasion, being surrounded by those who were in pursuit of him, he was put to death, and afterwards cut to pieces. An Angel of the Lord then appeared to [St.] Kevin saying: “A certain wretched man, who hath daily invoked thee to ward off danger from his soul, is slain on this day. Do you, therefore, act valiantly in the Lord’s name, and follow the demons who drag his soul to torments. For, although his body is destroyed, yet through the power of God, you shall snatch his soul from destruction.” Then, the holy Abbot felt comforted. Guided by the Angel, he was taken up from the earth to the higher regions of air, where he remained from the ninth hour to the following day, engaged in a contest with demons. In fine, through the Mercy of God, he release the wretched man’s soul from their power. Meantime, not knowing the cause of their holy Abbot’s absence, his monks felt sorrowful, on finding their venerable superior missing. When he returned to them, on the following day, he said: “O my brethren, bury the body of that culprit in your cemetery, for on his account, I ascended towards heaven. His soul is now liberated from the demons, and is at rest in God’s presence.” The monks did as they were commanded, while admiring those wonders wrought by the Almighty, through his holy servant. (J. O’Hanlon, “Lives of the Irish Saints” Volume 6, pp. 62-63)
