In this first volume of Brill Research Perspectives in Theology, the field of comparative theology is mapped with particular attention to the tradition associated with Francis Clooney but noting the global and wider context of theology in a comparative mode. There are four parts. In the first section the current field is mapped and its methodological and theological aspects are explored. The second part considers what the deconstruction of religion means for comparative theology. It also takes into consideration turns to lived and material religion. In the third part, issues of power, representation, and the subaltern are considered, including the place of feminist and queer theory in comparative theology. Finally, the contribution of philosophical hermeneutics is considered. The text notes key trends, develops original models of practice and method, and picks out and discusses critical issues within the field.
