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?
The primal error is believing in the need for man-made religions, the need to pay other men to intercede on your behalf to talk to God.
Unlike faith and spirituality, which arise from within (from God), religions are external schemes founded on 'soul control' and extracting tax-free money from masses of people. To accomplish this, they weaponize fear and psychological manipulation techniques perfected over millennia.
The belief that a dude in a Catholic collar can cast out demons, but one in a different collar cannot, is just that...a belief. Belief is thinking something is true without having any basis in objective fact, direct experience, math, or observable reality.
How much might possession in the first place be something that can happen when a person thinks he is not strong enough alone and needs the help of somebody more educated, or with "closer" connection to God to help if an evil spirit starts to pursue him, instead of having the faith that no matter what his personal weaknesses he has all the protection he needs when he believes that he has it if he just asks God for His help, and is able to believe that that help is always granted if asked? Kind of learned helplessness that can happen when a system is organized like most churches are, when there are these leaders who supposedly are the ultimate authority you'd always need to listen to?
