Within Christian thought, natural law is typically seen as a Catholic concept, indeed, as a concept that distinguishes Catholicism from other Christian communions, like Orthodoxy and Protestantism–the former of which rejects natural law as too cerebral and the latter as too optimistic, given fallen human nature. A new collection of essays from Cambridge University Press, Christianity and Natural Law: An Introduction, examines the place of natural law in the differing Christian traditions and attempts something of a synthesis–a jurisprudence of Christian law itself. The collection is edited by Cardiff University law professor Norman Doe, from whose scholarship I have benefitted in the past. Looks interesting. Here is the description from the publisher’s website:

Historically, natural law has played a pivotal role in Christian approaches to the law, and a contested role in legal philosophy generally. However, comparative study of natural law across global Christian traditions is largely neglected. This book provides not only the history of natural law ideas across mainstream Christian traditions worldwide, but also an ecumenical comparison of the contemporary natural law positions of different traditions. Its focus is not solely theoretical: it tests the practical utility of natural law by exploring its use in the legal systems of the churches studied. Alongside analysis of the assumptions underlying the concept, it also proposes a jurisprudence of Christian law itself. With chapters written by distinguished lawyers and theologians across the world, this book is designed for those studying and teaching law or theology, those who practice and study ecumenism, and those involved in the practice of church law.
