After Holy Communion, the child had a vision in which she assisted at the Sacred Mysteries in the Catacombs in company with St. Cecilia.

"I knelt," she said, "in a subterranean hall which seemed to be cut out in a mountain. Many people were kneeling around on the bare ground. Flambeaux were fastened to the wall, and there were two upon the stone altar which had a tabernacle, likewise of stone, and a door. A priest was saying Mass, all the people answering. At the end of it he took a chalice from the tabernacle. It looked like wood, and from it he distributed the Blessed Sacrament to the people, who received it on little white linen cloths spread carefully on their breast. Then they all dispersed."

This vision was a pledge that God had heard her and had accepted the sacrifice of her whole being. Her purity of heart and austerity of life rendered her worthy of figuring in the sacred cohort of early Christians who had drawn from the Most Blessed Sacrament their strength in the midst of torments. Her own life was to be a perpetual martyrdom and she, too, was to draw strength and courage from the same divine source. Like St. Cecilia she was to suffer for the Faith at a time of persecution, unbloody, it is true, but not the less dangerous to the Church. She, too, with heroism not inferior to that of the virgin-martyrs, was to confess her Redeemer denied and abandoned by the multitude.
