This paper reports on the social and personal relevance of religious faith entering into the situation of family stress due to the illness of a child with cancer. The expectations of religious faith may include, objectively, the actual physical healing of the child or the determination of the child's fate; it may include, subjectively, the hope for emotional support, the provision of moral guidance in time of difficulty, or an overarching life-view. There were major religious changes in 20% of the families. While all the major religious faiths in South Korea were represented in the study, 61% of the sample identified Christianity as their primary religious response.
