Let us add here a consoling fact, which we find in the life of St. Lutgarda. A celebrated preacher, named John de Lierre, was a man of great piety and well known to our saint. He had made a contract with her, by which they mutually promised that the one who should die first, with the permission of God, should appear to the other.
John was the first to depart this life. Having undertaken a journey to Rome for the arrangement of certain affairs in the interest of the Religious, he met his death among the Alps. Faithful to his promise, he appeared to Lutgarda in the celebrated cloister of Aywieres.
On seeing him, the saint had not the slightest idea that he was dead, and invited him, according to the Rule, to enter the parlor that she might converse with him. "I am no more of this world," he replied, "and I am come here only in fulfillment of my promise."
At these words Lutgarda fell on her knees and remained for some time quite confounded. Then, raising her eyes to her blessed friend, "Why," said she, "are you clothed in such splendor? What does this triple robe signify with which I see you adorned?"
"The white garment," he replied, "signifies virginal purity, which I have always preserved; the red tunic implies the labors and sufferings which have prematurely exhausted my strength; and the blue mantle, which covers all, denotes the perfection of the spiritual life."
Having said these words, he suddenly left Lutgarda, who remained divided between regret for having lost so good a Father, and the joy she experienced on account of his happiness.
