Cranmer next contributed to an English language liturgy of a more
Protestant character than the traditional
Roman Mass. The
Book of Common Prayer (BCP), as it came to be known, was heavily influenced by continental theologians, such as
Peter Martyr, Martin Bucer (both of whom Cranmer hosted in England), and
Hermann of Wied. Cranmer was credited with the first two editions of the BCP. The first edition, published in 1549, was very Catholic in its outlook. The communion service, lectionary, and collects in the liturgy were all based, with some changes, on the
Sarum Rite as practised in
Salisbury Cathedral. One change was due to an order of Convocation of the previous year, which dictated that Communion was to be given as both bread and wine.
The full prayer book included several liturgical texts, including the following: a daily office; readings for Sundays and Holy Days; the Communion Service; services for public
baptism, confirmation, matrimony, and visitation of the sick; rites for burials; and the Ordinal (added in 1550). The preface to this edition, which contained Cranmer's explanation as to why a new prayer book was necessary, began: "There was never any thing by the wit of man so well devised, or so sure established, which in continuance of time hath not been corrupted."
Although Cranmer is credited with the overall editorship and structure of the BCP, its detailed origins are obscure. A group of bishops and divines, drawn from both conservatives and reformers, met first at
Chertsey and then at
Windsor in 1548 and agreed only that "the service of the church ought to be in the mother tongue". Cranmer was a great plagiarist; even the opening of Preface (quoted above) was borrowed.
At the time of its introduction, popular rebellions by Roman Catholics, such as the
Prayer Book Rebellion, took place in
Devon, Cornwall, Oxfordshire, Buckinghamshire, and
East Anglia. Rather than slowing the pace of reform, these revolts emboldened Cranmer. Use of the Prayer Book was enforced by an
Act of Uniformity 1549 but it served only to antagonise Protestants and Roman Catholics in the realm. Outside of bloody reprisals in Cornwall, the Duke of Somerset and Cranmer did not encourage persecution. They refrained from it, as they feared invasion by Europe's powerful Catholic monarchs, especially Emperor Charles V.
Cranmer's second edition of the Book of Common Prayer was issued in 1552. This new edition was more
Protestant in nature, greatly toning down the sacrificial element in the
Eucharist, removing prayers for the dead, and removing many ceremonies, including the admixture of water with the wine at Communion, the exorcism of the salt and the triple immersion in baptism. At this time, Cranmer encouraged the destruction of art work, statues, and relics. More than 450 years later, these first editions of the BCP remain largely intact and authoritative for much of the Anglican world.
