This is a very good book for some basic comparison of major religions throughout the world. We gave it to our son, who is struggling with what he believes and he was thrilled. I also got one for us, just because we were interested in what other people believe. I doesn't cover ALL the world religions and it would be nice if it did have some more in it; but it is easy to understand and fills in a lot of the gaps in what we already knew.
This is a dangerous book. If you read it as it is, it seems okay, but if you look up many of his references, you will discover that what Ridenour often quoted as true is not. Nearly every section of the book quoted references that are now online and it is easy to discover that the statements in the book are based on misquotes or misinterpretations of the original material. One of the crutches Ridenour used was to quote people quoting others - for example - quoting a book that quotes the Book of Mormon. He did not look up the material in the Book of Mormon to see what it really says. Unfortunately for Ridenour, the Book of Mormon is now online and it is easy for a reader to find out what it really says and this often contradicts what Ridenour wrote. Almost every section of the book has errors. The book's cover claims "Over one million sold" - that means a lot of people got a lot of bad information. This book needs to be thoroughly rewritten and every reference needs to be checked for accuracy. I would estimate that approximately 25 percent of what is in it is wrong.
