You are certainly free to say that. However, I would disagree. I see absolutely nothing in Christianity which is different than any other religion. You have an organized priesthood which establishes a set of rules, which is to believed upon pain of pain. Aside from the name of the deity and minor variations in rituals and rules, you might as well be worshipping Ra.
As I said, once you remove the fluff, all religion is essentially the same. That is because there is one constant in religion.... human beings.
1. If you are talking about the external physical institutions and cultural practices, you would be right that these are for social organization like any other group.
2. However, if you read books like "Glimpses of the Devil" by Scott Peck or "Healing" by Francis MacNutt, you might understand how Christian healing prayer, for forgiveness of emotional, mental and spiritual blocks, has helped people to heal their minds and bodies of things that medicine could not achieve alone.
So by replicating the methods and studies in these books, you could see how it is true that praying in agreement and authority of Christ Jesus is able to influence factors that no other approach can do by itself. Even the practictioners I have heard of using Buddhist past life karma to trace the causes of people's mental issues still use Christian prayer to heal these conditions once they are identified.
I have not heard of other ways of curing demonic voices and obsessions permanently except for Christian methods of deliverance and exorcism. The medications can placate or dull down the symptoms but can't remove them or the cause. And the other methods of trying to use wicca or sorcery to will away the effects of negative spiritual factors tend to make these worse by adding to the manipulation of the affected person's mind instead of curing and freeing them of the negative conditions on their mental health and relations with others.

Healing Is Yours
where he found spiritual therapy to be superior and more cost-effective than his
neurosurgeon profession that he put aside to help more people full time by these methods.
When nothing else works, as with the schizophrenic patients that Dr. Peck treated and documented as the basis of his book, the prayer process for spiritual forgiveness and healing has been able to save people's minds and lives from conditions they had no control over, where some patients were too sick mentally to even administer treatment until AFTER they underwent the exorcism and deliverance process to identify and remove the causes.
I agree with Dr. Peck, who advocated for other psychiatric and medical professionals to take this field seriously, and pursue formal research and development in order to cure people.
