Religious voices were important in the early days of the contemporary field of bioethics but have now become decidedly less prominent. This is unfortunate because religious elements are essential parts of the most foundational aspects of bioethics. The problem is that there is an incommensurability between religious language and languages of public discourse such as the “public reason” of John Rawls. To eliminate what is unique in religious language is to lose something essential. This paper examines the reasons for the (...) marginalization of religion in bioethics, shows the limitations of Rawls’s notion of public reason, and argues for a more robust role for theology in articulating a new language for public discourse in bioethics.
