This paper critically explores key aspects of the gulf between Christian bioethics and the secular moral reflections that dominate contemporary bioethics. For example, in contrast to traditional Christian morality, the established secular bioethics judges extramarital sex acts among consenting persons, whether of the same or different sexes, as at least morally permissible, affirms sexual freedom for children to develop their own sexual identity, and holds the easy availability of abortion and infanticide as central to the liberty interests of women.

Birth, suffering, disability, disease and death were by medicine’s successes placed within a context of seemingly novel challenges that cried out for new responses. Secular bioethics rose in response to the demands of these new biomedical technologies in the context of a culture fragmented in moral pluralism. While secular bioethics promised to unite persons separated by diverse religious and moral assumption, this is a promise that could not be fulfilled.
