Book excerpt: Completely revised and updated for the postmodern age, So What's the Difference? gives you easy-to-understand, nonjudgmental answers to the question, "How does orthodox biblical Christianity differ from other faiths?" Here Fritz Ridenour explains the basic tenets of Protestantism, Roman Catholicism, Eastern Orthodoxy, Judaism, Islam, Hinduism, Buddhism, Jehovah's Witnesses, Christian Science, New Age, Mormonism, and other religions and belief systems of the world. You will also learn why relative thinking--the idea that there is no objective, absolute truth--has become the predominant mindset in our culture, and how you can respond. This bestselling guide will help you recognize the real differences between the Christian faith and other viewpoints and make it easier for you to explain and share your faith with others.
