The Book of Common Prayer at 350

James Wood discusses its importance in the New Yorker.

From the article...

The visitor has stumbled upon a service, Evensong, whose roots stretch back at least to the tenth century, and whose liturgy has been in almost continuous use since 1549, the date of the first Book of Common Prayer, which was revised in 1552, and lightly amended in 1662, three hundred and fifty years ago. The Book of Common Prayer was the first compendium of worship in English. The words—many of them, at least—were written by Thomas Cranmer, the Archbishop of Canterbury between 1533 and 1556. Cranmer did not cut his text from whole cloth: in the ecumenical spirit that characterizes the Book of Common Prayer, he went to the Latin liturgy that the English Catholic Church had used for centuries. In particular, he turned to a book known as the Sarum Missal, which priests at Salisbury Cathedral had long used to conduct services. It contained a calendar of festivals, along with prayers and readings for those festivals; and it held orders of service for Morning Prayer, Evening Prayer, and the Mass. 

The Missal was a handbook for priests and monks, though, not for the laity, and its language was Latin, not English. Cranmer wanted a prayer book in English, one that could be understood by ordinary people, even by those who could not read. To this end, he translated and simplified a good deal of the Sarum Missal: from the monastic services of Matins, Vespers, and Compline he fashioned Morning Prayer and Evening Prayer (commonly known now as Evensong), which are familiar to millions of members of the worldwide Anglican Church. He borrowed elements of the liturgy of the Reformed church in Cologne, and adapted a prayer of St. John Chrysostom from the Byzantine rite. He also wrote dozens of new prayers and collects, in a language at once grand and simple, heightened and practical, archaic and timeless.
