Madrid, Spain, Jun 4, 2025 / 10:47 am (CNA).

Sister Angela Musolesi was born in the small Italian town of Budrio on Dec. 8, 1954, the centennial year of the proclamation of the dogma of the Immaculate Conception.

A Franciscan nun, Sister Angela collaborated for 28 years with the renowned Italian priest and exorcist Father Gabriel Amorth. To expand the legacy of Amorth, who died on Sept. 16, 2016, in Rome at the age of 91, she founded the Children of Light association.

San Pablo Publishing has just published Sister Angela’s Spanish-langauge book “You Are My Ruin,” a volume that explains the causes of demonic possession and offers effective tools for confronting the actions of the devil.

Sister Angela does this with particular reference to the family, a field in which Our Lady of Fátima prophesied that the devil’s final battle against God and humanity will be fought.

Just a short distance from the statue of the fallen angel in Madrid’s Retiro Park, Sister Angela spoke with ACI Prensa, CNA’s Spanish-language news partner, about her latest work.

ACI Prensa: When the devil tells you “You are my ruin,” is it a desperate voice from the devil or a temptation to boost your ego?

Sister Angela: No, it’s a fear the devil has of me … he fears me, just as he feared Father Gabriele Amorth.

How is it that the devil is afraid of a human being?

Because we have Jesus within us, we have the resurrection of Jesus within us. [The devil] knows this well, and sometimes he has told us: “We know that you have already defeated us.” We speak in the name of Jesus, so we have already defeated all the demons, although perhaps we are a little afraid at times. I am not.

But you and Father Amorth are the Navy Seals (the elite force of the United States Navy) in the confrontation with the devil. How do we, as ordinary Catholics, make the devil fear us?

With the action of the Holy Spirit. The Holy Spirit bothers the devil a lot. It is the spirit of the risen Jesus. Sometimes, when I have prayed over someone, invoking the Holy Spirit, the devil has cried out: “You are hurting me, you are hurting me.” Only with the Holy Spirit. The more we have the Holy Spirit within us, the more we have the courage of Jesus. As St. Paul says in the Second Letter to Timothy: “God has not given us a spirit of fear but of courage, of strength, of wisdom, of light.”

Your book aims to better understand the enemy. Why is this goal important?

To understand his actions, how he works in the world and within us, in our minds. Because he primarily tries to attack the intellectual faculties and, through that, the heart. From the mind, from the head, through the brain, he confuses us.

The most widespread action in the world is that of Lucifer, who is the spirit of mental confusion, of the darkening of intelligence, of the inability to make decisions, and then also of madness, suicide, and death. This is what happens to young people who no longer have Jesus as a point of reference.

You began your apostolate in prisons. Does the devil move well behind bars?

He moves well in society. Certainly, prisoners, convicts, are the ones who suffer the most. But I can tell you that when I was in prison for 10 years, I would go and bring them Jesus. I would invoke the Holy Spirit, offer prayers of deliverance and healing, and the next time the prisoners would ask me: Sister, are you still saying that prayer?

You also have a great heart for ecumenism.

Absolutely, yes.

Are the different Christian groups more similar in how we conceive of the devil than in other doctrinal matters? Is this a point of unity that favors communion?

Yes, absolutely. Also because, for example, our evangelical brothers and Protestants in general have a great devotion to the Holy Spirit. And the Holy Spirit, as we have said, is what bothers the devil the most, because it is the spirit of Jesus. This is a common point. Even the final part of the Lord’s Prayer — “deliver us from evil.” When the devil manifests himself, and that is repeated several times, it makes him scream.

The most difficult thing is to get the devil to manifest himself, to make himself visible through a person who has a demonic action. But the most widespread action in the world is the ordinary action of the devil: mental confusion. It makes people believe he doesn’t exist, it makes them believe he doesn’t create problems.

The teaching that Father Gabriele Amorth has already spread is important because it says: Look, the devil is at work in the world. We must speak more about him, and everyone must apply Jesus’ words: “Whoever believes in me must — not can, must — command the devil, heal the sick, and raise the dead.”

So any of us, a layperson, a nun, or a normal priest, must command the devil and not be afraid. This teaching is sometimes disputed in the Catholic Church because there are priests who say no, that a normal priest, a normal nun, or a layperson cannot do that.

But Jesus was clear. Jesus said: “Whoever believes in me must not be afraid of the devil,” and he must do these things. This is the novelty of Father Gabriel Amorth’s teaching, which we are continuing. I say we because I founded the Children of Light during his lifetime, and we are continuing his teachings.

Tell us something special about the book that invites people to pick it up. What’s new about this book?

More than an explanation of the devil, it’s about how to free oneself from the devil, how to free marriages. It explains very well how to recognize the action of the devil in marriages that are about to break up. It explains what a person, a layperson, a wife can do for her husband if he has difficulties with fidelity, or what a mother can do for her children. This is very important; the book is important for this reason. It is the practical application of how to free oneself from the action of the devil.
