why are there sooo many catholic/christian evil demonic possession movies???When there are hardly any or No?

Roman Catholicism is founded mainly upon pagan influences, some of them occultic. Being the biggest cult in the world opens them up and they are easier for the devil and his demons to influence. Goddess worship, ritualistic robes, chanting, repetitive prayer, worship of idols and graven images, the consumption of what they believe to be blood and the body of someone, prayers to and for dead people....these are all practised in Satan worship and many other occult type groups. It is no accident that Roman Catholics suffer from the majority of demon-possessions. The failure and inadequacy of what they use to "fight" demon possession is laughable though as there is no such thing as "holy water". Even Jesus said that certain demons can only be removed by fasting and prayer(Matthew 17:21) (and that was only by the apostles). Today the only way to guarantee that you can't/won't be possessed by demonic forces is to repent of your sins toward God and place your faith in Jesus Christ (John 3:16, 14:6). When the believer is saved he/she is immediately indwelt by the Holy Spirit and Satan cannot abide/co-exist where God resides.

Nice name.

I don't think Muslims do that.
