This article is a response to the essays in this issue of the Journal of Anglican Studies on scriptural reasoning in the Anglican context, from the perspective of a Roman Catholic theologian, and one who is engaged in another kind of interreligious study, comparative theology. It sets out in general terms the distinctive character of comparative theology as an inquiry that crosses the borders between religious traditions. It draws attention to some of the common ground between comparative theology and scriptural reasoning and the character of each as theological disciplines, even while drawing out some of the distinctive marks of comparative theology. In this way it aims to shed light on how scriptural reasoning, even in its general form, is similar to other sustained efforts at interreligious learning, yet possessed of distinctive characteristics that make it interestingly different from the close reading that is comparative theology.
