American Protestants have expressed diverse views of how “faith” and “medicine” relate to health. Certain Protestants consider God the source of both illness and healing, while others attribute sickness to demons and wholeness to God. Some rely exclusively on either faith or medicine for healing, while others combine them. Over time, perceived tensions between faith and medicine have diminished, but not disappeared. There are numerous examples of Protestants praying in faith for healing and trusting God to heal through medical means. American Protestants have sometimes conflated rejection of medicine with “faith” and acceptance of medicine with “unbelief” – rather than following a line of logic that one may reject medicine and still lack faith, or accept medicine without wavering in faith.
