It is a cliché, but not an egregious one, that the most foundational concept in Christianity is “love,” whereas in Islam it is “justice.” Yet in this brilliant book, David L. Johnston shows not only how these two different traditions can be bridged, but also this very act can create a synergy that can make the world a better place. Highly recommended for any comparative theologian, and any other reader with an open theological mind.

David Johnston sets himself two important, interconnected, projects in this book, and brings them off superbly. One is to show that both love and justice are fundamental in both Christianity and Islam, contrary to the common stereotype that Christianity is all about love and Islam is all about justice. The other is to show that love and justice are not in tension with each other, as is commonly assumed, but, when rightly understood, are in harmony. I anticipate that the eyes of many readers will be opened, as were the eye of this reader, to Johnston’s demonstration of this fundamental affinity between Christianity and Islam. A valuable feature of Johnston’s presentation is that each chapter opens with a description of systemic injustice in some part of the world. The scholarship is impressive; but this is not just about scholarly texts, it’s about the real world.
