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.
