In 1837-38, the Presbyterian Church in the United States of America split in two. Suddenly, there were New School Presbyterians and Old School Presbyterians. Or perhaps it wasn't so sudden. How did this split occur? What was it over? What was New School Presbyterianism? What was Old School Presbyterianism? Samuel Baird, who compiled the first Digest of the Presbyterian Church in the United States of America, has given us a comprehensive history of this division, going all the way back to the beginnings of Presbyterianism in America in the 1600s. A History of the New School, and of the Questions Involved in the Disruption of the Presbyterian Church in 1838 is certainly not as well known as George Marsden's The Evangelical Mind and the New School Experience, but it is absolutely worth your time if you're wanting to understand 19th-century Presbyterianism better.
