"In the end, Reilly’s abbreviated framework is inadequate because original sin has been airbrushed out. It is in facing the realities of embedded disorders, pathologies, deformities, and evil that the [Aristotelian] ‘natural’ can best be understood. The movements Reilly criticizes are marked by a failure to confront embedded sin honestly and self-critically. That he deliberately avoids dealing with sin is unfortunate. Ultimately, it is not nature with which we have to deal, but the God of nature—indeed, not only ultimately but immediately. We must not suppose that, because Christian arguments have no purchase on cultural decision-making, we should mute their most explicitly Christian elements."
