In the year 1589, in the monastery of St. Mary of the Angels, in Florence, died a Religious who was much esteemed by her sisters in religion, but who soon appeared to St. Magdalen de Pazzi to implore her assistance in the rigorous Purgatory to which she was condemned. The saint was in prayer before the Blessed Sacrament, when she perceived the deceased kneeling in the middle of the church in an attitude of profound adoration. She had around her a mantle of flames that seemed to consume her, but a white robe that covered her body protected her in part from the action of the fire. Greatly astonished, Magdalen desired to know what this signified, and she was answered that this soul suffered thus for having had little devotion toward the August Sacrament of the Altar. Notwithstanding the rules and holy customs of her Order, she had communicated but rarely, and then with indifference. It was for this reason Divine Justice had condemned her to come every day to adore the Blessed Sacrament, and to submit to the torture of fire at the feet of Jesus Christ. Nevertheless, in reward for her virginal purity, represented by the white robe, her Divine Spouse had greatly mitigated her sufferings.
Such was the revelation which God made to His servant. She was deeply touched, and made every effort to assist the poor soul by all the suffrages in her power. She often related this apparition, and made use of it to exhort her spiritual daughters to zeal for Holy Communion.
