Michael Spencer was the first person I heard use the word revivalism. Any type of -ism refers to the belief in or practice of a particular thing. Some churches live in a revival subculture, where revival meetings, revival services and revival preachers are a regular part of ministry. I believe Iain Murray has written a book after Spencer’s own heart.
I just read an excellent review of Revival and Revivalism: The Making and Marring of American Evangelicalism, 1750-1858 at the 9Marks blog. Bobby Jamieson has spent some time with the text; the review is practically a study guide to the actual volume. Read the full review here.
*The review lists $33 as the price, which is retail. Amazon has it for $24.09, if you’re interested.
