"""On a subject as emotive as 'cults, ' it is very good to find in Unsafe Sects an analysis that is at once shrewd and judicious, knowledgeable and wide-ranging. Particularly valuable, and powerful, are Roger Olson's observations of a troubled and even 'unsafe' religious environment that he experienced firsthand. There is so much of value here."" -Philip Jenkins, distinguished professor of history, Baylor University ""In Unsafe Sects, Roger Olson empowers readers to identify for themselves the 'cult-like characteristics' of groups they should be wary of. Olson certainly doesn't pull any punches when it comes to critiquing cultish groups, but his treatment is always highly informed, deeply respectful, and uniformly fair. This well-written book is the most practically helpful work on 'cults' and 'unsafe sects' I've ever read, and I could not recommend it more strongly to all who are interested in identifying these groups."" -Greg Boyd, author of Letters from a Skeptic"
