Should patient be given a right to choose?

Most of the time, mental patients are automatically handled by attending or resident psychiatrist or psychologist. At this point, problems of spiritual nature are dealt with as cause by human nature explaining events as hallucinations or mere mental imagery when they are not. At some point, the belief of the psychiatrist clashes with the belief of the patient and more conflict ensued causing the problem to get more complicated. Should we give rights to patient to chose the psychiatrist to handle their case before any diagnostic procedure is started? Should psychiatrist or psychologist inform their patient of their religious affiliation prior to any psychiatrict or psychological procedure?
