Abstract: Hindu God, Christian God, an exercise in comparative theology, proposes that theology today is an interreligious discipline and illustrates this with reference to Christianity and Hinduism. Thinkers in many religious traditions share similar theological questions and problems in their quest to understand their faith, and so too use comparable methods for seeking right answers. However, much traditions emphasize their uniqueness and the necessity of faith, their thinkers usually teach, and often such teachings are recorded and become available as books that can be read and understood, and even translated. Religions are partially intelligible to outsiders; reasoning inquirers, in beginning to understand various beliefs and practices, cross even the most firmly fixed religious boundaries. In the process, they learn from the new tradition and also see their own tradition anew, by a comparative reading process. The best theology is therefore not only interreligious but also comparative, well versed in how different traditions have dealt with the same concerns.It is also dialogical, since authors must explain their ideas in ways that at least make sense to thinkers in the other traditions being discussed; they also need to be willing to learn from the critiques and responses of those other thinkers. Lastly, the discovery of common ground and shared concerns does not mean agreement; believers can still disagree and continue to hold views at odds with what others believe. Apologetics remains an issue.Hindu God, Christian God argues these points by bringing into conversation Christian theological beliefs – exemplified by the writings of Richard Swinburne, Hans Urs von Balthasar, Karl Rahner, and Karl Barth — and beliefs from some major Hindu traditions, including Nyaya [Logic], Vaisnavism [devotion to Visnu], and Saivism [devotion to Siva], as expressed in classic Sanskrit- and Tamil-language texts. Issues discussed include Hindu and Christian views of God's nature; proofs for God's existence; the true religion; incarnation or divine embodiment; revelation as offering definitive knowledge of religious truth.
