I got this book because of the wide array of religions covered but I didn't realize how biased the author was in describing the other religions. Instead of giving out just the facts, the author states his own opinion about the religion in relation to his own Christian background. For instance, he claims that certain Old Testament chapters are dated incorrectly too late and that is why Zoroastrianism could not have influenced the Bible but he doesn't say HIS PROOF for how it was incorrectly dated. If you're interested in a book that gives a neutral account of world religions, this IS NOT the book for you.
