No, being a religious person is not considered a mental disorder. The classification of mental disorders is determined by psychiatric and psychological professionals using established diagnostic criteria, such as those found in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
Religious beliefs and practices are a normal part of human diversity and have been present in various cultures throughout history. People may have different religious beliefs or spiritual practices based on their upbringing, cultural background, personal experiences, and philosophical inclinations. Holding religious beliefs and engaging in religious practices is a fundamental aspect of freedom of thought, conscience, and religion.
Mental disorders, on the other hand, are characterized by significant disturbances in cognition, emotions, behavior, or a combination of these, leading to distress or impaired functioning. They are clinical conditions that can be diagnosed by trained mental health professionals based on specific criteria outlined in the DSM-5 or other classification systems.
It's essential to recognize and respect the diversity of beliefs and practices, including religious ones, as long as they do not harm others or infringe on their rights. People's religious or spiritual beliefs should not be stigmatized or pathologized as mental disorders simply due to differences in perspectives.
