In this article the author first gives an introduction to his own approach to comparative theology (CT). After some introductory considerations, an outline of the idea and foundation of CT is given and is contrasted with traditional approaches to other religions; the methods, goals, and also the limits of CT are discussed; CT is differentiated from religious studies and the theology of religions; finally, CT is defended against some of its most important critiques. All in all, the author presents an approach to CT that suits Christian confessional theology, yet is open to Islamic theology as well, and which is inviting to theology as a dialogical enterprise which should be performed by Muslims and Christians and other religious believers together.
