Searching for a Universal Ethic: Multidisciplinary, Ecumenical, and Interfaith Responses to the Catholic Natural Law Tradition ed. by John Berkman and William C. Mattison III (review)

Despite its generalist title, this book is the result of a very specific and multilayered textual history. The core of the volume is the official English translation of the International Theological Commission (ITC) document In Search of a Universal Ethic: A New Look at the Natural Law, which alone composes nearly a quarter of the book's text. Following five years of work, the commission first published the document in 2009. The following year, a special session at the annual meeting of the Society of Christian Ethics was convened for the purpose of discussing the document, and this session served as the impetus for the present volume. Along with Berkman and Mattison's introductory chapter, the remainder of the book is composed of responses to the document from no less than twenty-two scholars representing a broad range of religious and philosophical commitments.

If there is anything approaching a consensus among the volume's diverse respondents, it is a nearly unanimous verdict that the ITC document offers a more winsome portrayal of natural law theorizing than anything that has been promulgated in official Church documents during the last several decades. As Serge-Thomas Bonino, OP (one of the document's coauthors), explains, the commission endeavored to situate the doctrine of natural law within "a larger theological framework that is both Christological and Trinitarian" (98). Many respondents praise the document's more nuanced and open-ended analysis of the natural law—one that accommodates a wide variety of sociocultural contexts—as well as the document's clarity and boldness in articulating a Christian (and specifically Christological) interpretation of the natural law tradition.

The high level of admiration bestowed on the document does not mean that it is without its detractors, however. Some of the more critical respondents maintain that, in spite of the commission's "new look" at the natural law, many of the classical objections to the doctrine still hold. Gilbert Meilaender, for example, lauds the document's Christological commitments but worries that it fails to explain how this facet of the Catholic natural law tradition can help us to develop a universal ethic on which all can agree (226). Others express doubts precisely about what is "new" in this new look at the natural law. This is perhaps best reflected by Jennifer Herdt's remark that "the note of epistemological modesty repeatedly sounded by In Search of a Universal Ethic seems to ring hollow" (210). In other words, the move toward less specificity regarding moral norms may in fact render the natural law inadequate as a framework for dialogue across cultures.

Given the perennial subject matter of this volume, the editors have done an excellent job of balancing a vast range of perspectives and approaches to the natural law, rendering it useful to a wide audience. The sheer number of authors could easily have resulted in a collection that reflected breadth at the expense of depth. Thankfully, however, the presence of the ITC text as the locus of discussion helps to ground the conversation in such a way that all of the authors are fruitfully engaging the same set of questions. For this reason, it is among the best volumes currently available for those who wish to engage the most creative and rigorous thinking within the natural law tradition.
