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.
