Book excerpt: In this introduction to the Zondervan Guide to Cults and Religious Movements, Dr. Gomes defines the characteristics of a "cult of Christianity" and why such a group subverts the search for spiritual truth. He explains the emotional and spiritual appeal of cults, who is susceptible, and the techniques cult leaders use to attract members. This book, in dealing with a wide range of issues relating to cults and religious movements in general, complements the other books in the series, all of which focus on specific religious groups. -- Why this series? This is an age when countless groups and movements, old and new, mark the religious landscape in our culture, leaving many people confused or uncertain in their search for spiritual truth and meaning. Because few people have the time or opportunity to research these movements fully, these books provide essential information and insights for their spiritual journeys. Except for this book, each book in the series has five sections: - A concise introduction to the group - An overview of the group's theology -- in its own words - Tips for witnessing effectively to members of the group - A bibliography with sources for further study - A comparison chart that shows the essential differences between biblical Christianity and the group -- The writers of these volumes are well qualified to present clear and reliable information and help us discern religious truth from falsehood.
