**THE EXORCISM OF NICOLA AUBREY
****By Father Michael Muller, C.Ss.R.
****It is indeed a remarkable fact that, as the devil made use of Luther,
an apostate monk, to abolish the Mass and deny the Real Presence, in
like manner God made use of His arch-enemy, the devil, to prove the
Real Presence. He repeatedly forced him publicly to profess his firm
belief in it, to confound the heretics for their disbelief, and
acknowledge himself vanquished by Our Lord in the Blessed Sacrament.
For this purpose God allowed a certain Mme. Nicola Aubrey, an
innocent person, to become possessed by Beelzebub and twenty-nine
other evil spirits. The possession took place on the eighth of
November, 1565, and lasted until the eighth of February, 1566.
Her parents took her to Father de Motta, a pious priest of Vervins,
in order that he might expel the demon by exorcisms of the Church.
Father de Motta tried several times to expel the evil spirit by
applying the sacred relics of the holy cross, but he could not
succeed; Satan would not depart. At last, inspired by the Holy Ghost,
he resolved to expel the devil by means of the sacrament of Our
Lord’s Body and Blood. Whilst Nicola was lying in a state of
unnatural lethargy, Father de Motta placed the Blessed Sacrament upon
her lips, and instantly the infernal spell was broken; Nicola was
restored to consciousness, and received Holy Communion with every
mark of devotion. As soon as Nicola had received the sacred Body of
Our Lord, her face became bright and beautiful as the face of an
angel, and all who saw her were filled with joy and wonder, and they
blessed God from their inmost hearts. With the permission of God,
Satan returned and again took possession of Nicola.
As the strange circumstances of Nicola’s possession became known
everywhere, several Calvinist preachers came with their followers,
to “expose this popish cheat,” as they said. On their entrance, the
devil saluted them mockingly, called them by name, and told them that
they had come in obedience to him. One of the preachers took his
Protestant prayerbook, and began to read it with a very solemn face.
The devil laughed at him, and putting on a most comical look, he
said: “Ho! Ho! My good friend; do you intend to expel me with your
prayers and hymns? Do you think that they will cause me any pain?
Don’t you know that they are mine? I helped to compose them!”
“I will expel thee in the name of God,” said the preacher, solemnly.
“You!” said the devil mockingly. “You will not expel me either in the
name of God, or in the name of the devil. Did you ever hear of one
devil driving out another?”
“I am not a devil,” said the preacher, angrily, “I am a servant of
Christ.”
“A servant of Christ, indeed!” said Satan, with a sneer. “What! I
tell you, you are worse than I am. I believe, and you do not want to
believe. Do you suppose that you can expel me from the body of this
miserable wretch? Ha! Go first and expel all the devils that are in
your own heart!”
The preacher took his leave, somewhat discomfited. On going away, he
said, turning up the whites of his eyes, “O Lord, I pray thee, assist
this poor creature!”
“And I pray Lucifer,” cried the evil spirit, “that he may never leave
you, but may always keep you firmly in his power, as he does now. Go
about your business, now. You are all mine, and I am your master.”
On the arrival of the priest, several of the Protestants went away –
they had seen and heard more than they wanted. Others, however,
remained; and great was their terror when they saw how the devil
writhed and howled in agony, as soon as the Blessed Sacrament was
brought near him. At last the evil spirit departed, leaving Nicola in
a state of unnatural trance. While she was in this state, several of
the preachers tried to open her eyes, but they found it impossible to
do so. The priest then placed the Blessed Sacrament on Nicola’s lips,
and instantly she was restored to consciousness. Rev. Father de Motta
then turned to the astonished preachers, and said: “Go now, ye
preachers of the new Gospel; go and relate everywhere what you have
seen and heard. Do not deny any longer that Our Lord Jesus Christ is
really and truly present in the Blessed Sacrament of the altar. Go
now, and let not human respect hinder you from confessing the truth.”

During the exorcisms of the following days, the devil was forced to
confess that he was not to be expelled at Vervins, and that he had
with him twenty-nine devils, among whom were three powerful demons:
Cerberus, Astaroth, and Legio. On the third of January, 1556, the
bishop arrived at Vervins, and began the exorcism in the church, in
the presence of an immense multitude.
"I command thee, in the name and by power of the real presence of Our
Lord in the Blessed Sacrament, to depart instantly," said the bishop
to Satan in a solemn voice.
