Persons suffering with psychosis may develop religiously based delusions and/or hallucinations. This is not surprising, as they are experiencing something which is unexplainable and religious explanations lend themselves and may even give a person some solace.
This may happen whether a person was religious or not prior to the episode. I have never seen anything to indicate that a previously religious person is more or less likely to develop religious symptoms during a psychotic episode.
That is entirely different than saying that religiousness itself is a psychiatric symptom or illness.
The article you link to only provides the abstract but does not appear to include any kind of scientific evidence. It is, rather, just one persons hypothesis and even it's conclusion is not clear.
Of course this is a topic which merits discussion, but no professional organization that I am aware of has taken the position that you and others take here. In fact, the major diagnostic manual specifically excludes religious belief from pathology.
If you wish to pursue this as a part of your studies, do so. But continue to take this position in the face of evidence to the contrary is much more in line with the definition of a delusion than is religion.
