This article provides a brief background of how Comparative Theology is understood today, to point out features of how it is practiced that are responsive to issues peculiar to contemporary Catholicism, and to suggest how a version of CT might be developed that is more consistent with Islamic traditions of thought on related issues. In order to accomplish this last goal, a brief introduction to the traditional “Islamic sciences” is provided. It will be suggested that an Islamic Comparative Theology (ICT) can be understood as a multidisciplinary field that draws on several Islamic sciences, as well as research in religious studies. I argue in favor of a blurring of the distinction between Comparative Religion and Comparative Theology, and point out that relevant discussions are to be found across a variety of traditional Islamic sciences, but that it would be advantageous to collect these discussions together and to augment them with information gleaned from both secular and Islamic approaches to the teachings of Muslim thinkers about theological issues, broadly understood, in comparison with what is found in non-Islamic traditions in such a manner to enrich our own understandings of the issues and those with whom we engage in dialogue.
