This book is not only an introduction to the entire Zondervan Guide to Cults and Religious Movements series, but also a quick-reference guide to the groups and movements discussed in the series. Truth and Error brings together in one volume the charts from the various guides that show how the groups and movements differ theologically from historic orthodox Christianity. Each chart is introduced by the general editor, Alan Gomes. The books in the series that do not have comparison charts are introduced and summarized. Each book in the series includes - A concise introduction to the group or topic - An overview of the group's or movement's theology -- in their own words - A biblical response - Tips for witnessing effectively to members of the group - A bibliography with sources for further study -- Most books also include a comparison chart that shows the essential differences between biblical Christianity and the group. The charts from these books are reproduced in Truth and Error.
