Spiritual Healing and Medical Treatment: Not Either-Or, but Not Interchangeable

Prayer, spiritual care and faith-based healing can matter deeply to people who are ill. This page explains what each can and cannot do, and why none replaces medical care.

Two different questions

Faith, prayer and spiritual community are central to how many people face illness. That is a fact about human life, and this page treats it with respect. It also asks a separate, practical question: when someone is sick, which needs does spiritual care meet, and which needs does medical treatment meet? The answer is that they are not interchangeable, but they do not have to compete.

If you or someone near you has a medical emergency, call 911 (in the United States) or your local emergency number. Do not wait for a ritual, prayer session or healer.

What spiritual care can offer

The National Cancer Institute notes that religious and spiritual values are important to patients coping with cancer. [1] It also separates the two ideas: religion is a specific set of beliefs and practices, usually within an organized group, while spirituality is an individual's sense of peace, purpose and connection to others, and beliefs about the meaning of life. [1] The same source says it is not known for sure how spirituality and religion are related to health. [1]

So the honest summary is that spiritual support can be a real part of coping, meaning and comfort. That is different from showing that it changes the course of a disease.

What research has measured about prayer for others

Researchers have tested one narrow form of spiritual practice: intercessory prayer, where people pray for patients who are also receiving usual care. The studies are limited in what they can say, and they say nothing about a believer's own prayer, faith or community.
2 findings · 2 limited or unclearThe colour follows the evidence label on each card.

  1. Does intercessory prayer, added to usual care, change health outcomes?

    Insufficient evidence

    A Cochrane review of 10 trials (7,646 patients) found results that were equivocal and concluded the evidence does not support a recommendation for or against it. [2]

  2. Did prayer help recovery after heart bypass surgery?

    No good evidence of benefit

    In the STEP trial, prayer itself had no effect on complication-free recovery. Patients certain they were being prayed for had more complications than those who were unsure. [3]

These results do not measure faith, spiritual wellbeing or the value of being supported by one's community. They test whether prayer by strangers changes a medical outcome. For fuller background, see prayer, faith and health.

How to hold both

  • Keep your treatments and your spiritual practice. One does not have to be given up for the other.
  • Tell your care team about your beliefs. Ask what spiritual support your own provider or hospital can arrange.
  • Be wary of any healer, group or teacher who tells you to stop medicine, skip a test or delay care. See spiritual practices and mental health.
  • Never stop a prescribed medicine because of a spiritual instruction. Talk to your prescriber first.
  • Ceremonies belong to their communities. Where a practice is restricted or sacred, this site does not describe it; read Indigenous knowledge: public and restricted.

Frequently asked questions

Is it wrong to pray or use spiritual healing when I am ill?

No. The National Cancer Institute says religious and spiritual values are important to many patients coping with cancer. [1] The concern is only about using it instead of effective medical care.

Does prayer cure disease?

Trials of intercessory prayer, where others pray for patients, found no clear effect, and a Cochrane review said the evidence does not support a recommendation for or against it. [2] These trials do not measure personal faith or community support.

Can spiritual healing replace medicine for a child?

No. A review of child deaths found that most of the children who died in faith-healing families had conditions with survival rates above 90% when treated medically. [4]

Can I use both spiritual care and medical treatment?

Yes, and many people do. Tell your care team what you are doing so they can support you and check for any safety concerns.

What if a healer tells me to stop my medicine?

Do not stop. Speak with your prescriber or pharmacist first, and read about red flags in traditional healing practice.

Where the risk lies: replacing care
The main harm is not spiritual practice itself. It is using it in place of treatment that works. A pediatrics study of 172 child deaths in families who used faith healing instead of medical care estimated that 140 of the children had conditions for which survival with medical care would have exceeded 90%. [4] The authors concluded that when faith healing is used to the exclusion of medical treatment, the number of preventable child fatalities and suffering is substantial. [4] This was a review of selected cases, not a measure of how common such outcomes are, but it shows what is at stake with children, who cannot decide for themselves.

The same pattern applies to adults. The FDA warns that "natural" or alternative cancer products can cause harm by delaying or interfering with proven treatments. [5] For a closer look at warning signs, see when traditional healing delays needed medical care.
