Petronilla is said to have been a spiritual daughter of Saint Peter, who took her with him to Rome where she became paralysed. Simon Magus having asked him why, if he could perform miracles, he allowed his daughter to remain infirm, Saint Peter answered that “It was expedient for her.” Then he added, “Nevertheless, to show the power of God, she will rise from her bed and walk.” Then he called her, and she rose and was restored to her full health. An officer who greatly admired her beauty sent soldiers to her to ask her to be his wife, but she replied: “If he wants me to marry him, let him not send rough soldiers to woo me, but respectable matrons, and give me time to make up my mind.” But before Flaccus could obtain matrons to convey his offer, Petronilla died.

At Aquileia, the holy martyrs Cantius, Cantian and Cantianilla. For their attachment to the Christian faith they were condemned to capital punishment with their tutor Protus in the time of the emperors Diocletian and Maximian.
At Torres in Sardinia, St. Crescentian, martyr.
At Comana in Pontus, in the time of the emperor Antoninus, St. Hermias, a soldier. Being miraculously delivered from many horrible torments, he converted his executioner to Christ and made him partaker of the crown which he himself obtained first by having his head struck off with the sword.
At Verona, St. Lupicinus, bishop.
At Rome, St. Paschasius, deacon and confessor, who is mentioned by Pope St. Gregory.
And in other places, many other holy martyrs, confessors and virgins.
Thanks be to God.
Dom Prosper Gueranger:
Though the Church makes but a simple commemoration of this illustrious virgin in the office of this day, we will not fail to offer her the homage of our devout veneration. On the twelfth of this month, we kept the feast of the noble virgin and martyr, Flavia Domitilla: it is probable that Aurelia Petronilla was also of the imperial family of the Flavians. The early traditions of the Church speak of her as being the spiritual daughter of the Prince of the Apostles, and though she did not like Domitilla lay down her life for the Faith, yet she offered to Jesus that next richest gift — her virginity. The same venerable authorities tell us also that a Roman Patrician by name Flaccus, having asked her in marriage, she requested three days for consideration during which she confidently besought the aid of her Divine Spouse. Flaccus presented himself on the third day, but found the palace in mourning and her family busy in preparing the funeral obsequies of the young virgin, who had taken her flight to Heaven, as a dove that is startled by an intruder’s approach.
In the eighth century the holy Pope Paul I had the body of Petronilla taken from the Cemetery of Domitilla on the Via Ardeatina. Her relics were found in a marble sarcophagus, the lid of which was adorned at each corner with a dolphin. The Pope had them enshrined in a little church which he built near the south side of the Vatican Basilica. This Church was destroyed in the sixteenth century in consequence of the alterations needed for the building of the new Basilica of Saint Peter, and the relics of Saint Petronilla were translated to one of its altars On the west side. It was but just that she should await her glorious Resurrection under the shadow of the great Apostle who had initiated her in the Faith and prepared her for her eternal nuptials with the Lamb.

You disdained the pleasures and honours of the world, and your virginal name is one of the first on the list of the Church of Rome, which was your mother. Aid her now by your prayers.
