Our goal in this paper is two-fold. First, we aim to clarify two ways in which contemporary Christian bioethicists have erred, on Engelhardt’s account, in their attempts to do bioethics within a distinctively non-Christian idiom, namely, either (1) by rejecting a principal metaethical thesis or (2) by misrepresenting a principal moral-epistemological thesis of natural-law ethics, properly construed. Second, we intend to show not only that Engelhardt can and should endorse the Christian bioethicists’ use of non-Christian moral idioms in the public (...) square but also—perhaps to the surprise both of his critics and of his supporters—that he does, in fact, do so.
