The book's chief maker, Thomas Cranmer, Archbishop of Canterbury, created it as the authoritative manual of Christian worship throughout England. But as Jacobs recounts, the book has had a variable and dramatic career in the complicated history of English church politics, and has been the focus of celebrations, protests, and even jail terms. As time passed, new forms of the book were made to suit the many English-speaking nations: first in Scotland, then in the new United States, and eventually wherever the British Empire extended its arm. Over time, Cranmer's book was adapted for different preferences and purposes. Jacobs vividly demonstrates how one book became many--and how it has shaped the devotional lives of men and women across the globe.
