Faith healing is the practice of prayer and gestures (such as laying on of hands) that are claimed to elicit divine intervention in spiritual and physical healing, especially the Christian practice. Believers assert that the healing of disease and disability can be brought about by religious faith through prayer and/or other rituals that, according to adherents, stimulate a divine presence and power. Belief in such divine intervention is derived from religious belief.
Claims "attributed to a myriad of techniques" such as prayer, divine intervention, or the ministrations of an individual healer can cure illness have been popular throughout history. There have been claims that faith can cure blindness, deafness, cancer, AIDS, developmental disorders, anemia, arthritis, corns, defective speech, multiple sclerosis, skin rashes, total body paralysis, and various injuries. Miraculous recoveries have been attributed to many techniques commonly classified as faith healing. It can involve prayer, a visit to a religious shrine, or simply a strong belief in a supreme being.
Many people interpret the Bible, especially the New Testament, as teaching belief in, and the practice of, faith healing. According to a Newsweek poll, 72 percent of Americans say they believe that praying to God can cure someone, even if science says the person doesn't stand a chance. Unlike faith healing, advocates of spiritual healing make no attempt to seek divine intervention, instead believing in divine energy. The increased interest in alternative medicine at the end of the 20th century has given rise to a parallel interest among sociologists in the relationship of religion to health.
Faith healing can be classified as a spiritual, supernatural, or paranormal event, and, in some cases, belief in faith healing can be classified as magical thinking. The American Cancer Society states "available scientific evidence does not support claims that faith healing can actually cure physical ailments". "Death, disability, and other unwanted outcomes have occurred when faith healing was elected instead of medical care for serious injuries or illnesses." When parents use faith healing in the place of medical care, some children have died that otherwise would have been expected to live. Similar results are found in adults.
