I comment on two papers by Koenig and colleagues that advocate the integration of religion into routine psychiatric practice. In my opinion, their selective overview of research, although useful, lacks balance. It omits any mention of the literature on worldwide scandals over child sex abuse (and other abuses of power) perpetrated and facilitated by religious authority within several faith groups. There is no mention of damaging ‘religiously informed’ treatments such as sexual orientation conversion therapy, which is still practised in the UK despite widespread condemnation. Their recommendations for clinical practice conflate association with causation. They do not offer practice guidance on managing the impact of power imbalances associated with religion in multicultural societies. In summary, despite more than a decade of research and debate, there are still no generally accepted ways of avoiding boundary violations where psychiatrists introduce religion into their clinical practice.
