I am not entirely sure what to make of this book, but it's not a cheap-thrills read. It's meticulous, intelligently written, and compassionate towards those who seem to be afflicted by evil. Martin seeks neither to mock nor to exploit the suffering, and seems to be a sincere and likable fellow.
Having said that, I doubted the professional decisions made in many of the case studies in this book, and felt bewildered that these "possessed" folks were declared mentally stable by the psychiatrists and/or psychologists who assessed them. Given their symptoms, I would have diagnosed most of them in a heartbeat, referred them to a doctor to prescribe psychiatric medication, then followed with an appropriate course of therapy.
I wonder, would I have been correct to do so? Or, would I have only exacerbated their problems? I can't say for certain, but it seems to me that trying standard treatment protocols prior to exorcism might be prudent, since validating a person's belief they are possessed by demons would no doubt cause further trauma and potentially worsen their illness, in the event that you are mistaken (that said, I am well aware that psychiatric intervention frequently makes things worse for people, too).
I do wonder how the people who were exorcised turned out, years later, after their life-altering experiences. If they were truly possessed, one might expect a full and lasting recovery. If they were actually suffering from mental illness a relapse would have been inevitable. Given that we don't know their real identities, we can never know how their lives played out, decades on. It is also said in the literature on this topic that a person can be both mentally ill and under demonic influence which would presumably be much harder to sort out.
Malachi Martin writes a compelling set of life stories that whisks aside the veil that surrounds our daily lives to reveal an unseen world that he believes has the potential to affect us profoundly, for better or worse. Judging from what I've read before about possession, it seems to me that the people most commonly claiming to be afflicted by demons are those who, firstly, believe such beings exist and, secondly, that they have the power to possess humans. That said, Martin writes that most of the afflicted persons in this handful of cases were either never religious at all or had abandoned the faith of their childhood somewhere along the way.
So are we wrong to assume that it all comes down to what you believe? Surely, if you believe you have made a pact with Satan or become dependent on one of his minions, it will no doubt affect you profoundly, whether or not such creatures are actually harassing you. Belief is powerful. But then how to explain these unbelievers who appear possessed and are helped by exorcists? Well, I was not convinced that any of these folks were truly unbelievers in the supernatural, deep down, despite what they might have claimed in their daily lives.
However, I'm certainly not willing to say such things as possession are definitely unreal just because we cannot explain them from a scientific perspective. I simply do not know. The older I get, the less I feel sure about how the great world spins. What I do know, though, is that communities of faith and the beliefs that support them can be an important part of people's overall health, so I do not scoff at spiritual beliefs. That said, I would think long and hard and exhaust all other efforts before telling someone in my care I thought they were possessed by a demon. Needing medical care for a mental health problem seems to me far less stigmatizing, shaming, and sinister than needing to have (religiously-speaking) spiritual filth cleansed from your tormented soul.
