Self-Mutilation and Biblical Delusions: A Review

ObjectiveTo review the literature for cases of deliberate self-harm that directly reference Bible verses as a motivation for action and discuss predictive factors of such behaviors and post-injury management strategies.MethodsSixteen cases of self-mutilation prompted by Biblical verses were found in the existing literature. The authors also describe a novel case of penile amputation prompted by a verse from the Gospel of Matthew.ResultsFour biblical verses associated with self-mutilation were found, all from the Gospel of Matthew. All patients presented with a diagnosis of psychosis at the time of the event. Other common themes include substance abuse, guilt over sexual acts, absence of pain or regret, and destruction of the severed body part.ConclusionsPatients with symptoms of psychosis may misinterpret various verses from the Gospel of Matthew as instructions to engage in self-injurious behavior. Psychiatrists should be aware of these four verses to understand their significance and potentially forestall these behaviors.
