Not the Same God challenges a familiar assumption. That Judaism, Christianity, and Islam are three paths to the same God, and argues that these traditions produced different gods, shaped by different histories, pressures, and goals. Yahweh, the Father, and Allah are not alternate names for a single being. They are rivals. Each claims to be the only one.

The book examines religion as a competitive system operating within the Economy of Belief.  Witty, unsentimental, and grounded in historical narrative, it reframes monotheism not as a shared inheritance, but as a long and unfinished contest over who gets to be called the One.
