I was a Comparative Religions Major and this book answers all the major questions about the worlds major religions. If you are a religious studies student, or you just have questions about religions other than your own, this is an awesome source book.
I never read the whole book... as a new researcher of religion, it was just too complicated for me, i couldn't keep my focus. I'm sure it would be a better companion to someone who is more familiar with religion. But I wouldn't recommend it to anyone who wants a more simple, straightfoward, easy to read book to learn about religion.
A great FAQ book on the world's major religions. Christianity, Judaism, Islam, Buddhism, Hinduism, Confucianism, Taoism and Shinto.
