This is an extraordinary book - intellectually rigorous but not turgid, historically informed but not tedious, theologically astute but not doctrinally reified. Written by Catholics, and ostensibly for Catholics, the book's relevance extends well beyond the Roman Catholic Church to believers everywhere. The parodying so commonly found in Christian writing about other religions has been avoided in this book. Jewish, Muslim, Hindu, Buddhist and New Age devotees will without chagrin recognize themselves. With both religion and its stereotyping playing such a fractious role in our globalized world, this book will serve as a trustworthy guide for readers who want their engagement with the religious other to be marked by wisdom and integrity.
