This work investigates the possibility and necessity of interreligious dialogue between Christianity and the major world religions of Islam, Hinduism, and Buddhism. Hans Küng, a prominent theologian, utilizes a framework of historical analysis and comparative theology to argue that peace between religions is a prerequisite for peace among nations. He examines the foundational texts and core tenets of these traditions to identify common ground and points of divergence, advocating for a model of mutual understanding rather than conversion or syncretism.

The subject matter points to a dense, scholarly text intended for readers with an interest in academic theology and comparative religious studies. The framing suggests a rigorous, systematic approach to interfaith engagement that prioritizes historical accuracy and respectful discourse.
