As a spiritual person, no matter what your faith or creed, if you are SINCERE and truly looking to help others, you need to be sure you have a clear calling to help others to be rescued from dark entities.
If you are looking for fame or glory in the paranormal world, the area of demonology should be avoided. As a minister it has not brought parishioners running to my doorstep. And more times than not your collegues who have not been trained in this type of ministry think you are a loon.
Yet there are many who boast to be a demonologist or exorcist without proper training in pastoral counseling let alone psychology who attempt to claim fame in the paranormal community. If you deal with real people with real issues you need real training. Waving a cross, sprinkling Holy water and reciting a few prayers will do no good if you have no inner resources from which to draw upon if things go bad. You need to be called out from the crowd to minister to the oppressed.
