I'm feeling a little bit conflicted on this. On one hand, I've had Steve Prothero as a professor. He's extremely intelligent and completely engaging - more so than any other college professor I've come across. Great human being in person too. I found the book to be fair and well-researched, definitely a clear and worthy introduction to many major world religions. His unique method of introducing the problem/ solution that each religion offers is fantastic. Christianity addresses sin through salvation, Islam addresses pride through submission, etc. For its content, I think this should be the standard introduction to world religions for any high school or undergraduate course. There is never a dull moment and he draws fascinating parallels and brings in interesting anecdotes. Further, the Professor makes a very valid point. In our politically correct world, people try to underplay important differences in doctrine, ritual, and worldview and paint all religions as one. Forget about disparity between religions, huge differences exist within religions: the God of Abraham is very unlike the God of Moses or the God of Second Isaiah. This is where the Professor makes a valid and important point - these religions are not the same, so we need to stop pretending they are! Not only is it false, but it's intellectually demeaning.
Now, here's where the conflict comes in. I completely disagree with the entire premise of the book, that "God is not one." In fact, the unity of Godhead is the one thing that all religions seem to share. The very definition of God itself presupposes an all-inclusiveness; if there is a God, God MUST be one. In the same way that Christopher Hitchens took on Islam's phrase "Allahu Akbar" with his book "God is not great" - Professor Prothero here seems to take on the Jewish phrase "Jehovah Echad" with this book: "God is not one." I noticed Huston Smith's biographer posted a defense of the perennial philosophy on here, which is a philosophy I find myself subscribing to on a very deep level. I think the issue behind the conflict is that people often confuse religion and God. God exists independent of religion. God may be one, but there is no doubt that the religions that attempt to reach God are very very different. However, just because particular religions have different opinions about God, does not mean that they are speaking about separate gods. Each person I meet has different opinions and conclusions about me, but that does not mean that there are multiple versions of me. I am one person. We cannot dismiss God's unity simply because various folks approach deity in unique ways.
All religions talk about two realms, the heavens and earth, matter and spirit, prakriti and purusha, etc. To truly understand God as he/she is we need to approach it on the spiritual realm, not the material realm. All that religions and rituals and even words can possibly discuss are in the material world. They are just the finger pointing at the moon, not the moon itself. As the Tao Te Ching says "The way that can be spoken of is not the constant way; the name that can be named is not the constant name." To the mystics, which were not deeply addressed in the book, there is a shared experience of a common underlying Reality because they reach God through the spiritual realms, not through material dogma, ritual, and myth. Jehovah and Vishnu are worlds apart, but the Kabbalistic Ain Soph and Vedantic Brahman are one in the same. So here, perhaps the better book title would have been "Religion is not One." Not as catchy, but perhaps more accurate.
Plus sides:
- Informative about major world religions
- Unbiased in portraying the good, bad, and ugly of various traditions
- Fun to read and not a dull moment, very engaging
- Great problem/ solution method - simple but not simplistic
Down sides:
- Focuses on mainstream religion, ignores the esoteric/ mystical paths
- Assumes religious differences mean God is not one
Recommendation:
Buy it. Even if you don't subscribe to the idea of "God is not one" - it will be a great and informative read, especially on lesser-known religions such as the Yoruba, Taoism, and Confucianism.
