From the just-referenced article:
Pope Francis says that the only way to fight Satan is to “defend yourselves with the word of God” and not try to enter into dialogue or argue with the devil, who, he says, tries to seduce the weak.
No, Your Holiness. This is wrong. What a Protestant response. The orthodox way for
Catholics to defend against Satan is to stay in the state of grace through the Sacraments, available only through the Roman Catholic Church. Listen to any talk by a respectable traditionalist priest, whether or not he is an exorcist himself, and he will confirm that. The "word of God" (the Bible) cannot do what the sacramental grace of Jesus Christ can do.
Disorder is the devil's invitation and opportunity, disorder through...
mortal sin, including hidden (unconfessed) grave sin
untreated mental illness
intimacy with the occult -- any form of the occult
