This book is more of a position paper than a history book. There are many points in this book that become suspect with a deeper review of American history from 1849 to 1925. America was transforming during a time of civil war, yellow journalism, the Spanish American war, a presidential assasination, the growth of a progressive political movement, World War I, and a depression just to name a few. However, the authors point to the Civil War and the use of an instument during "worship" as the most logical reason churches from the north and south split. No mention is made of the rise of the Social Gospel movement beginning in 1988 and how it caused many religious organizations to seperate into more fundamental or more progressive groups. There is more evidence that the split spoke of in this book was more of a result of the "Social Gospel" movement. Do your own research and decide for yourself.
