The latest health care legislation, which promotes prevention and health screening, ultimately depends for its success on recognition of people's values concerning the technologies being employed, not just the interventions' technical virtues. Values concerning the deterministic nature of a condition and what groups should be targeted rest on a sense of what is morally, often religiously right in a given health circumstance. This paper looks at a number of leading-edge case examples--breast cancer genetic screening and family decision-making, and newborn screening and biobanks--in examining how the choices made at the individual, family, and societal levels rest on faith in a higher source of efficacy and moral perspectives on the measures that can be taken. Qualitative responses expressing people's attitudes toward these technologies underscore the importance of considering faith-based values in individual decisions and collective policies on their use. These examples are considered in the context of the historic interplay between science and religion and recent definitions and models of health which incorporate physical, emotional, and social elements, and most importantly, are expanding to incorporate the religious and spiritual values domains.
