The words of the Book of Common Prayer have permeated deep into the English language all over the world. For nearly 500 years, and for countless people, it has provided a background fanfare for a marriage or a funeral march at a burial. Yet this familiarity also hides a violent and controversial history. When it was first produced the Book of Common Prayer provoked riots and rebellion, and it was banned before being translated into a host of global languages and adopted as the basis for worship.
