Question: The Alternative Service Book 1980 (ASB) was the first complete prayer book, produced by the Church of England since what year, its name derives from the fact that it was merely as an alternative to the Book of Common Prayer (BCP), is the short title of a number of related prayer books used in the Anglican Communion, as well as by the Continuing Anglican, "Anglican realignment" and other Anglican churches?
Context: Anglican eucharistic theology is diverse in practice, reflecting the comprehensiveness of Anglicanism.  Its sources include prayer book rubrics, writings on sacramental theology by Anglican divines, and the regulations and orientations of ecclesiastical provinces.  The principal source material is the Book of Common Prayer; specifically, its eucharistic prayers; and Article XXVIII of the Thirty-Nine Articles.  Article XXVIII comprises the foundational Anglican doctrinal statement about the eucharist, although its interpretation varies amongst churches of the Anglican Communion, as well as between those of Anglo-Catholic and Evangelical churchmanship. The Book of Common Prayer (BCP) is the short title of a number of related prayer books used in the Anglican Communion, as well as by the Continuing Anglican, "Anglican realignment" and other Anglican churches.  The original book, published in 1549 in the reign of Edward VI, was a product of the English Reformation following the break with Rome.  Prayer books, unlike books of prayers, contain the words of structured (or liturgical) services of worship.  The work of 1549 was the first prayer book to include the complete forms of service for daily and Sunday worship in English.  It contained Morning Prayer, Evening Prayer, the Litany, and Holy Communion and also the occasional services in full: the orders for Baptism, Confirmation, Marriage, "prayers to be said with the sick", and a funeral service.  It also set out in full the "propers" (that is the parts of the service which varied week by week or, at times, daily throughout the Church's Year): the collects and the epistle and gospel readings for the Sunday Communion Service.  Old Testament and New Testament readings for daily prayer were specified in tabular format as were the Psalms; and canticles, mostly biblical, that were provided to be said or sung between the readings . The Book of Common Prayer according to the use of the Episcopal Church contains the liturgy used in its worship services and for other religious gatherings.  The BCP and its predecessors are descended from the prayer books used by the Church of England.  There have been four versions of the United States Prayer Book that have been used.  They are known by the year of issuance: 1789, 1892, 1928, and 1979.  In 1784, in order to bring about the consecration of America's first bishop, Samuel Seabury of Connecticut, in Scotland, a "concordat was signed by Seabury and the Scottish bishops" who consecrated him pledging use of the Scottish Eucharistic Rite by the Episcopal Church then, thus "following Scottish structure" (with some of its liturgy derived from Eastern Orthodox) and circumventing the Church of England. The Traditional Anglican Communion (TAC) is an international communion of churches in the continuing Anglican movement independent of the Anglican Communion and the Archbishop of Canterbury.  The TAC upholds the theological doctrines of the Affirmation of St. Louis and an Anglo-Catholic interpretation of the Thirty-Nine Articles.  Each of the respective jurisdictions utilizes a designated Book of Common Prayer deemed free of innovation.  Most parishioners of these churches would be described as being traditional Anglo-Catholics in their theology and liturgical practice.  Some parishes use the Anglican Missal in their liturgies.  The TAC is guided by a college of bishops from across the communion and headed by an elected primate. Prior to the revision of the Anglican Church of Canada's (ACC) Book of Common Prayer (BCP) in 1962, the national church followed the liturgical calendar of the 1918 Canadian Book of Common Prayer.  Throughout most of the twentieth century, the situation in Canada resembled that which pertained in much of the Anglican Communion: There was uncertainty as to whether post-Reformation figures (with the exception of the martyred Charles I) could or should be commemorated.  In the words of the calendar's introduction, "New names have been added from the ancient calendars, and also from the history of the Anglican Communion, without thereby enrolling or commending such persons as saints of the Church."  The 1962 revision added twenty-six post-Reformation individuals, as well as commemorations of the first General Synod and of "The Founders, Benefactors, and Missionaries of the Church in Canada."  Of the calendar days, twenty-eight were highlighted as "red-letter days" — that is, days of required observation. The Alternative Service Book 1980 (ASB) was the first complete prayer book produced by the Church of England since 1662.  Its name derives from the fact that it was proposed not as a replacement for the "Book of Common Prayer" ("BCP") but merely as an alternative to it.  In practice, it was so popular that the various printers had to produce several editions very quickly and churches which retained the BCP drew attention to this fact as something to be noted.  The Prayer Book Society was soon complaining that it was becoming hard to find a church which used the old prayer book and that theological colleges were not introducing students to it.  It has now been replaced by "Common Worship". Common Worship is the name given to the series of services authorised by the General Synod of the Church of England and launched on the first Sunday of Advent in 2000.  It represents the most recent stage of development of the Liturgical Movement within the Church and is the successor to the "Alternative Service Book" (ASB) of 1980.  Like the ASB it is an alternative to the "Book of Common Prayer" (BCP) of 1662, which remains officially the normative liturgy of the Church of England. The Church of England (Continuing) is part of the Continuing Anglican Movement.  The church was founded in England on 10 February 1994 at a meeting chaired by David Samuel held at St Mary's, Castle Street, Reading, in reaction to the use of the "Alternative Service Book" and to the ordination of women.  The church holds to the unmodified Thirty-Nine Articles of Religion of the Church of England and to the 1662 "Book of Common Prayer" which alone is used by its parishes for worship. The Orthodox Anglican Communion was established in 1964, as a self-governing worldwide fellowship of national churches in the Anglican tradition.  The Orthodox Anglican Communion was one of the first such communions to be formed outside of the See of Canterbury and therefore is not part of the Anglican Communion.  The Orthodox Anglican Communion adheres to the doctrine, discipline and worship contained in the classic Anglican formularies, especially in the 1662 English, 1928 American, 1929 Scottish and 1962 Canadian Books of Common Prayer. The Prayer Book Society is a charity in England that "is established for the advancement of the Christian religion as set forth in the Book of Common Prayer; and, in furtherance of this Object, for the promotion of the worship and doctrine enshrined in the Book of Common Prayer and its use for services, teaching and training throughout the Church of England and other Churches in the Anglican tradition." .  In 2012 the Charity Commission for England and Wales permitted the society to simplify its objects in order to allow it to undertake a number of new activities closely related to its previous activities.  According to the Society it has over 4,500 members and 51 branches throughout England.  The society considers itself to be a sister society of the Prayer Book Society of the USA, the Prayer Book Society of Canada, the Scottish Prayer Book Society and the Prayer Book Society in Australia.  The society's patron is Charles, Prince of Wales and the ecclesiastical patron is Richard Chartres, the Bishop of London.
