Since the first edition was published in 1965, Walter Martin's The Kingdom of the Cults has been the leading reference work on the major contemporary cult systems. With an emphasis on the currently active, proselytizing cults, The Kingdom of the Cults continues to be a crucial tool in counter-cult ministry and evangelism. While remaining true to Walter Martin's original tone and text, this updated edition includes substantial new information. Relevant and accurate materials have been reintroduced from the original editions, preserving Dr. Martin's unique voice and defense of the faith. Scholarly yet readable and engaging, The Kingdom of the Cults evaluates each cult's history and beliefs, contrasting individual teachings with true biblical theology. Readers will find apologetics help in dealing with cults not only at home but also overseas.
