Oliver O'Donovan is widely regarded as one of the preeminent Protestant Christian ethicists of our time. His teaching and scholarship have exerted a profound influence on countless moral theologians. This collection of essays honoring O'Donovan shows how the various contributors - themselves distinguished scholars - have developed their own thinking through serious engagement with O'Donovan's work. More than simply assessing his work, this volume builds upon, expands, and even corrects a few lines of an agenda for Christian ethics that O'Donovan has been instrumental in building. A probing essay by Oliver O'Donovan himself concludes the book.
