Here is an interesting article “When Satan Pulls Wool Over Our Eyes” in *Crisis *Magazine.
The Catholic Church has always taught the reality of Satan. There are some modernist theologians who don’t believe in Satan.
Satan wants people to not believe that he exists–that way he can get more to fall into mortal sin .
"Bl. Pope John Paul II said “the evil that surrounds us today, the disorders that plague our society, man’s inconsistency and brokenness, are not only the results of original sin, but also the result of Satan’s pervasive and dark action.” Pope Benedict (then Cardinal Ratzinger) recognized that Satan “is a powerful reality . . . evident if we look realistically at history, with its abyss of ever-new atrocities which cannot be explained by reference to man alone.” Pope Paul VI warned that we are struggling not “only against one devil, but against a frightening multiplicity of them.”
"These Popes, Paul VI, John Paul II, and Benedict XVI, are among the holiest men of the past century. Living in the light of truth, and being so close to the light, they could truly understand the pernicious power of darkness. If they could see this so clearly, and warned us so vehemently, ought we not listen?
“The Catechism has a frightening observation in the commentary on the final phrase in the Lord’s Prayer: “But deliver us from evil.” It teaches, “In this petition, evil is not an abstraction, but refers to a person, Satan, the Evil One, the angel who opposes God” (no. 2851).”
The “Church” can “teach” all it wants.
Now tell me, please, what is Satan’s temptation on Sunday morning?
I submit that empty pews testify that Satan is often prominent in the neighborhood. And is the “good neighbor Satan” mentioned in homilies? There is nothing inherently wrong for a priest to “preach to the choir” about Satan. There is always the chance that a Satan talk will be repeated to others. And perhaps, a “choir member” will find a reason to keep coming. This does not mean that a homily has to scare people. It means that the intentions of Satan need to be understood.
Obviously, there are churches where there is standing room only for the Sunday Holy Sacrifice of the Mass rain or shine. But that is no reason for the other parishes to ignore Satan’s influence.
