Johnson takes a unique approach to church history. He examines twelve crises that motivated the evolution of Christianity. In his survey of Church history, he chronicles the story from the first century and the "birth and adolescence" of Christianity to postmodernism, a feat which no other introduction can claim. His chapters examine the basic conflicts that gave permanent shape to Christian theology, and, to a lesser degree, church institutions.
This book is a whirlwind tour through the nearly two millennia of Christianity. It touches on a bewildering array of topics and historical figures, but hardly anything is covered in much depth. This is, however, a wonderful source book for further study. It includes a list for further reading and other interesting sources are mentioned in the endnotes.
