Because the Bible says very little about these phenomena, the subject of ghosts, apparitions, and hauntings is controversial among followers of Christ. Still, many reliable people have had experiences relating to these phenomena, and their accounts are so strikingly similar that a simple denial of their existence seems unwise.
During the Middle Ages, people often believed that ghosts were “earth-bound” spirits of the dead, who, for some reason or another, were trapped here on earth after death. There is no biblical support for this point of view, although it probably was associated with the Roman Catholic view of purgatory generally held at that time. The Protestant Reformation brought a rejection of Roman Catholic teaching on purgatory, along with the consensus that hauntings are produced by evil spirits who impersonate people and recreate events.2 However, even this explanation leaves some questions unanswered.
Some observers speculate that there may be some presently unknown natural process by which especially horrible events involving intense emotions (such as murders) may be “recorded” and replayed again and again through the centuries. Some believe there is evidence that poltergeists3 are a natural phenomena involving telekinesis.4 Often young women — usually adolescent girls — are associated with such poltergeist phenomena. Witnesses claim that when a particular young woman is removed from the vicinity of the occurrences, the poltergeist phenomenon ceases.
But, again, there is no compelling evidence proving the existence of telekinesis as a natural phenomenon, nor is there any scientific evidence that intensely emotional events can produce “psychic recordings.” It is unlikely that we will have a definitive answer to this question soon. And since this whole area borders on the occult — an area stringently forbidden by Scripture (Â Deuteronomy 18:9-13 ) — it is wise for Christians to be cautious and not delve too deeply into it.
Christians, and even thoughtful unbelievers, should bear in mind that whatever the ultimate cause of a particular ghostly manifestation, it may serve a subtle satanic purpose — stimulating a morbid curiosity in the preternatural that could draw susceptible people into occultism. People who pursue interest in the occult — even if their interest is “scientific” — can be drawn into occultism more deeply. Their “scientific interests” are prone to degenerate into personal obsession.
