The daughter of a certain prince had entered a monastery, where the discipline was so relaxed, that, although she was a young person of good dispositions, she advanced but little in virtue. By the advice of a good confessor, she began to say the Rosary with the mysteries, and became so changed that she was an example to all. The other religious, taking offence at her for withdrawing from them, attacked her on all sides, to induce her to abandon her newly-begun way of life.
One day while she was repeating the Rosary, and praying Mary to assist her in that persecution, she saw a letter fall from above. On the outside were written these words: “Mary, mother of God, to her daughter Jane, greeting;” and within : “My dear child, continue to say my Rosary; withdraw from conversation with those who do not help you to live well ; beware of idleness and vanity ; take from your cell two superfluous things, and I will be your protectress with God.” The abbot of that monastery soon after visited it, and attempted to reform it, but he did not succeed ; and one day he saw a great number of demons entering the cells of all the nuns except that of Jane, for the heavenly mother, before whose image he saw her praying, banished them from that. When he heard from her of the devotion of the Rosary which she practiced, and the letter she had received, he ordered all the others to repeat it, and it is related that this monastery became a paradise.
There lived in Rome a woman, called Catherine the beautiful, who led a very sinful life. Hearing St. Dominic once preach on the devotion of the most holy Rosary, she had her name inscribed in the book of the confraternity, and began to recite it, but did not abandon her sinful life. One evening a youth, apparently a noble, came to her house, whom she received courteously. When they were at supper, she saw drops of blood falling from his hands while he was breaking a peace of bread, and then she observed that all the food he took was tinged with blood. She asked him what that blood meant? And the youth answered, that a Christian should take no food that was not tinged with the blood of Jesus Christ, seasoned with the memory of his passion and death. Amazed at this, she asked him who he was. “Soon,” he answered, ” I will show you;” and when they had withdrawn into another room, the appearance of the youth changed, and he showed himself crowned with thorns, his flesh torn, and said to her: Do you wish to know who I am? Do you not know me? I am your Redeemer. Catherine, when will you cease to offend me? See how much I have suffered for you. You have grieved me enough, change your life.” Catherine began to weep bitterly, and Jesus, encouraging her, said: “Now begin to love me as much as you have offended me; and know that you have received this grace from me, on account of the Rosary you have been accustomed to recite in honor of my mother.” And then he disappeared. Catherine went in the morning to make her confession to St. Dominic; and giving to the poor all she possessed, led so holy a life that she attained to great perfection. The Virgin often appeared to her; and Jesus himself revealed to St. Dominic, that this penitent had become very dear to him.
The blessed Alan de la Roche relates of a lady, named Dominica, who was accustomed to recite the Rosary, that she gave up this devotion, and afterwards became so poor, that in desperation she stabbed herself in three different places. But just as she was breathing her last, and the devils came to take her to hell, the most holy Mary appeared to her, and said to her: “My daughter, you have forgotten me, but I have not been willing to forget you, on account of that Rosary which you have for a time recited in my honor. And now,” she added, “if you will continue to recite it, I will restore life to you, and also the possessions you have lost.” Dominica was restored to health, and continuing the practice of reciting the Rosary, recovered her possessions, and at her death was again visited by Mary, who commended her fidelity, and she died a holy death.
