"Religious horror films, as most Western audiences know, is dominated by Catholic imagery, from crucifixes and vials of holy water to bibles with tattered pages and worn-down priests. The God and the devil are warring for our mortal souls, and the heroic priests on screen are the only ones able to fight in that battle. If you grew up Catholic like me, these films are terrifying reminders of what could await us after death.
But if you grew up with a little less of that signature guilt pounded into your head every Sunday, the typical religious horror may not be keeping you up at night. Thankfully, religious horror is much more diverse than it may seem. From tackling doomsday cults to Korean mysticism, filmmakers around the globe are using their experience with different versions of faith to create horror beyond the scope of Jesus and the Holy Spirit."
