Schizophrenia is a registered disease, not a religion, and vice versa for christianity.
I agree but just from comparing the symptoms how do we tell the difference?
There are many things that mimic schizophrenic so even though one can have the symptoms doesn't mean it will be schizophrenia.
Symptoms include...
Hallucinations
A hallucination involves one of the five senses (sound, sight, taste, touch, or smell), but occurs when there is nothing in the environment to stimulate the sense organ.
The most common type of hallucination that schizophrenics experience is an auditory hallucination.
(claims of god talking to them, seeing angels, seeing the Virgin Mary which is often accompanied by the smell of roses...)
Delusions
A delusion is essentially a strongly held, but false belief that something which is not real is actually real, even when there is obvious proof or evidence to the contrary.
(believing in a global flood, believing the human race came from only two people, believing evolution is false)
Disorganized speech
When a personâs speech is disorganized, he may often quickly go off the topic and talk about a variety of unrelated things. His speech may also be incoherent, making no sense to anyone who is listening.
(speaking in tongues)
Grossly disorganized behavior
Grossly disorganized behavior can show up in a variety of ways. For example, the person may dress in a bizarre or grossly inappropriate way
(this one I don't think I can get on about, unless I can make fun of the Popes hat)
Catatonic behavior
Catatonic behavior involves the personâs movement, posture and responsiveness. For example, he may be completely unresponsive to his surroundings, as in a catatonic stupor. He may stand or sit in a rigid and / or bizarre position. When someone is catatonic, he may be very resistant to any attempt to move or reposition him. Catatonia may also involve excessive, excited movement that has no purpose and no trigger.
(Perhaps the convulsions from faith healing, I can think of other things that would be a stretch)
Negative Symptoms
The negative symptoms of schizophrenia are passive in nature. They affect the personâs thinking, emotion and behavior and can be the most devastating of all the symptoms. Three of the most common are flat affect, alogia, and avolition.
Alogia
Alogia, which refers to impoverished thinking, occurs when the personâs speech is very limited in terms of content and lacks spontaneity.
(This would be a huge stretch, but for the religious this does seem to fit when explaining why the belief is held)
