What is Satan's greatest fear?

Many people are fascinated by exorcisms, demonic
possession, and extraordinary spiritual warfare. But
according to experienced exorcists and the wisdom of
the Church, the most powerful weapon against the devil
is something you may be taking for granted.

Drawing from the 1991 film The Rite and the Church's
centuries-old understanding of spiritual warfare, Father
Robert McTeigue, S.J. explains why sacramental
confession remains the Catholic's greatest defense
against evil.

While extraordinary cases of demonic
activity capture headlines, the overwhelming majority of
spiritual battles are won unassumingly in the
confessional, where sin is forgiven and souls are
restored to grace.

So what's keeping you from experiencing God's mercy in the confessional?
