Book of Common Prayer (1559) in the context of Book of Common Prayer (1662)

The Book of Common Prayer (BCP) is the title of a number of related prayer books used in the Anglican Communion and by other Christian churches historically related to Anglicanism. The first prayer book, published in 1549 in the reign of King Edward VI of England, was a product of the English Reformation following the break with Rome. The 1549 work was the first prayer book to include the complete forms of service for daily and Sunday worship in English. It contains Morning Prayer, Evening Prayer, the Litany, Holy Communion, and occasional services in full: the orders for Baptism, Confirmation, Marriage, "prayers to be said with the sick", and a funeral service. It also sets out in full the "propers" (the parts of the service that vary weekly or daily throughout the Church's Year): the introits, collects, and epistle and gospel readings for the Sunday service of Holy Communion. Old Testament and New Testament readings for daily prayer are specified in tabular format, as are the Psalms and canticles, mostly biblical, to be said or sung between the readings.

The 1549 book was soon succeeded by a 1552 revision that was more Reformed but from the same editorial hand, that of Thomas Cranmer, Archbishop of Canterbury. It was used only for a few months, as after Edward VI's death in 1553, his half-sister Mary I restored Roman Catholic worship. Mary died in 1558 and, in 1559, Elizabeth I's first Parliament authorised the 1559 prayer book, which effectively reintroduced the 1552 book with modifications to make it acceptable to more traditionally minded worshippers and clergy.

The Act of Uniformity 1558 (1 Eliz. 1. c. 2) was an act of the Parliament of England, passed in 1559, to regularise prayer, divine worship and the administration of the sacraments in the Church of England. In so doing, it mandated worship according to the attached 1559 Book of Common Prayer. The act was part of the Elizabethan Religious Settlement in England instituted by Elizabeth I, who wanted to unify the church and abolish the influence of the Catholic Church in England and Wales. Other acts concerned with this settlement were the Act of Supremacy 1558 (1 Eliz. 1. c. 1) and the Thirty-Nine Articles.

The 1552 Book of Common Prayer, also called the Second Prayer Book of Edward VI, was the second version of the Book of Common Prayer (BCP) and contained the official liturgy of the Church of England from November 1552 until July 1553. The first Book of Common Prayer was issued in 1549 as part of the English Reformation, but Protestants criticised it for being too similar to traditional Roman Catholic services. The 1552 prayer book was revised to be explicitly Reformed in its theology.

During the reign of Mary I, Roman Catholicism was restored, and the prayer book's official status was repealed. When Elizabeth I reestablished Protestantism as the official religion, the 1559 Book of Common Prayer—a revised version of the 1552 prayer book—was issued as part of the Elizabethan Religious Settlement. It was this pattern which formed the basis for the 1662 Book of Common Prayer, which remains the official liturgical book of the Church of England.
