Do Muslims and Christians worship the same God Yale University religion scholar Miroslav Volf-widely known for the famous Yale course he co-teaches with Tony Blair-argues that this question lies at the root of the 21st century's most sensitive, and critical, geopolitical concerns.

3.6 billion people, the majority of the world's population, profess one of these two faiths. And while it has long been an uneasy coexistence, the post-9/11 world has seen tensions rise as leaders and the faithful on both sides of the divide seek either to see only differences or to unduly emphasize these traditions' similarities. Volf examines the hidden agendas and meanings behind various sources-from today's news stories to text straight out of the Bible and the Qur'an-in search of the fullest picture of where these faiths diverge and where they meet.

Religious wars become real wars, Volf argues, and enormous contemporary interest in the theological and historical intersections of Islam and Christianity reflects just how much is at stake. Persuasively argued and expertly researched, God vs. Allah offers a constructive vision for a new pluralism and hope for building a common future.
