In Reisberg there lived a Canon regular named Arnold, who was very devoted to the Blessed Virgin. Being at the point of death, he received the sacraments, and calling his religious to him, begged them not to leave him at the last moment.
Scarcely had he said this, when he began to tremble violently and roll his eyes; cold sweat fell from him, and with an agitated voice he exclaimed: "Do you not see those demons who would seize me and carry me to hell?" Then he cried: "My brothers, invoke for me the help of Mary; I trust in her that she will give me the victory."
They immediately began to recite the Litany of Our Lady, and at the words, ‘Holy Mary, pray for him,’ the dying man cried: "Repeat, repeat the name of Mary, for I am even now at the tribunal of God." He stopped for a moment, and then added: "It is true that I did it, but I have done penance for it." Then turning to the Virgin, he said: "Oh Mary, I shall be delivered if thou wilt help me." The demons soon after made another attack, but he defended himself by blessing himself with the crucifix, and invoking Mary.
Thus he passed the whole night, but when morning dawned, Arnold, restored to serenity, joyfully said: "Mary, my Lady, and my refuge, has obtained for me pardon and salvation." Then beholding the Virgin, who summoned him to follow her, he said: "I come, oh Lady, I come." He made an effort to rise, but not being able to follow her with the body, gently expiring, he followed her with his soul, as we hope, to the blessed kingdom of glory.
