I am Protestant, baptized and raised, but I do not ever hear about Protestant pastors driving out demons in exorcisms. We know the spiritual world is real, so exorcisms have to be real by default. Demons can call out our sins to accuse us and drag us down with them, so that is also universal between Catholics and Protestants.
So what is the defining difference that gives Catholics the power to do the exorcisms and not Protestants?
Do they teach in a way that gives more divine authority? Are we doing something wrong? Or is it withholding information within the Catholic church?
Read the books by Books by Gabriele Amorth, experienced exorcist. Remember frens, not long ago, demonic possession and exorcism were made fun of!
If you saw the movie, you learned that confronting demons is not something you want to try at home. This is not a battle of men, but of principalities and powers. There is one Spirit but many gifts: not every Christian is called to cast out demons.
Demons as fallen angels are strong and powerful, tricky, seductive, scary, liars, etc.
Serious possessions or manifestations are not something to take lightly.
We need not fear demons, as they are subject to the Lord. But we are not to engage with them. I am fine with shouting out "BE GONE SATAN, in the name of the Lord Jesus Christ!" I say the St. Michael prayer regularly, sometimes more than once a day. I have Holy Water and other sacramentals in my home. We are indeed not defenseless. But leave exorcism to those trained to deal with all the tricks and treachery the demon will throw back at them.
