Faith Community Nurses have common beliefs, principles, ethics, and a level of trust with their population making them well-positioned to positively impact parishioners. FCNs provide support for people’s spiritual needs and nursing care. This makes FCNs a vital and approachable resource for parishioners when seeking advisement and assistance regarding their mental healthcare. In this article, we define red flags as suicidal idealization, mania, and psychosis, which if not promptly assessed and referred for treatment may result in serious harm or death. These red flags are predominately found in people with schizophrenia, depression, bipolar disorder, and post-traumatic stress disorder. People with mental illnesses can develop red flags that require timely assessments. FCNs are readily accessible to people with mental illnesses and can screen for red flags of suicidal idealization, mania, and psychosis.
