In the 21st century, a vast and growing array of new religions and sects has emerged. Some are familiar traditions, moving further into prominence; others seem to have been made up almost overnight. The sheer number can be overwhelming and confusing. Many people know the names but have no idea what these sects and religions really believe. In this new reference, Nigel Scotland systematically examines fifty key groups in modern religion, including Mormonism, Kabbalism, Wicca, Scientology, and UFO religions. Each brief, but thorough chapter walks through the origins, core beliefs, recent developments, and present practices of the movement. Accessible and concise, this reader-friendly guide is a great reference for people who don't have time to study each in depth but want a quick overview in understanding.
