This volume draws together leading theologians and Christian ethicists from across the globe to critically engage with and reflect upon Gerald McKenny, widely acknowledged as one of the most original and important Christian ethicists working today. The essays highlight the significance of McKenny's interventions with a range of important debates in contemporary theological ethics, ranging from analyses of the Protestant conception of grace to bioethics and medicine. Reaching far beyond the work of Gerald McKenny, this multifaceted volume is a high-level resource for students and scholars of theological and philosophical ethics. Theological ethicists owe a tremendous debt to Gerald McKenney; the following work is a modest response to that debt. As the introduction notes, he has been a "patient and gracious" reader of others' while at the same time presenting an ethics of grace attentive to nature. I'm tempted to say that he offers the best version of a Reformed ethic available today, but the ecumenical and theological diversity of the authors and chapters demonstrate that such a sentiment is far too limiting. Mawson and Martens are to be commended for bringing attention and honor to the importance of McKenney's work.
