The book aims to promote unity among believers by examining major theological controversies from a biblical perspective, using simple, layman’s terms.

Miller urges readers to read the book from chapter one onwards to understand the consistent “study pattern” used throughout, rather than skipping to the chapter that interests them most.

The author states his belief that while this work may not solve all problems of division, it is an effort inspired by a “heart of grief” for the divisions among believers.
