Can faith help patients heal? Veteran doctor reveals what he’s witnessed firsthand
Dr Marc Siegel’s new book, *The Angels Among Us*, examines how spirituality, compassion and modern medicine may intersect during serious illness. Drawing on clinical experiences, research and historical cases, Siegel argues that faith and hope can support resilience, while stressing that they do not replace medical treatment or guarantee recovery.
Siegel cites data suggesting that 70% of doctors believe in God and 55% have witnessed what they consider medical miracles. The book includes cases involving unexpected recoveries from brain injuries or coma, spiritual experiences during critical illness, his father’s prolonged survival on dialysis, Ronald Reagan’s recovery after being shot, and Alcoholics Anonymous co-founder Bill Wilson’s spiritual awakening.
- Siegel explores faith’s possible role in recovery.
- He says spirituality complements, rather than replaces, medicine.
- The book recounts unexplained recoveries and acts of compassion.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Faith, hope and spiritual meaning demonstrably influence psychological resilience and can complement medical treatment by reducing stress, improving medication adherence and strengthening social support networks. Patients' subjective experiences of spiritual comfort during illness merit respect and serious study, and the placebo effect—itself a mind-body phenomenon—is now recognised as having measurable health benefits. Dr Siegel's central claim is modest: that spirituality supports healing alongside medicine rather than replacing it, which aligns with evidence that holistic care addressing patients' whole selves, including their beliefs and values, produces better outcomes.
The case against
Unexpected medical recoveries occur through natural physiological processes and advances in modern medicine, yet are often retrospectively reinterpreted as spiritual through confirmation bias and selection bias. The statistics cited—that doctors believe in God or report witnessing miracles—reflect doctors' pre-existing beliefs rather than proof of efficacy; without randomised controlled trials, one cannot distinguish correlation from causation or account for other factors (patient age, treatment intensity, underlying physiology) that might explain outcomes. Framing faith as contributive to healing, however carefully caveated, risks encouraging vulnerable patients to view spiritual conviction as a material factor in recovery, potentially leading some to delay necessary medical intervention or hold unrealistic expectations.
