Collection of essays, excerpts and articles from thoughtful historians' and authors' various attempts to try to define evangelicalism. My limited understanding of evangelical Christian church history made the first half of the book difficult to comprehend at times and I plan to re-read at some point in the future. But the second half, that dealt with more contemporary times, was a page-turner even for a layman. Really appreciated this work as my personal introduction to what seems like a broad, amorphous subject.
