The Prayer Book Society of Canada or PBS is an organization within the Anglican Church of Canada which "promotes the understanding and use of the Book of Common Prayer as a spiritual system of nurture for life in Christ". Founded in 1985, the PBS seeks to "ensure the retention of the doctrine and worship of the Book of Common Prayer as required by the Solemn Declaration of 1893, the founding document of the autonomous Anglican Church of Canada."
The Book of Common Prayer (BCP) used in Canada was originally compiled in 1962, and is a national expression of a tradition of Christian worship stemming from the original BCP published by the Church of England in 1549. The original 1549 BCP was itself a revision of the medieval forms of worship in use within the English Church prior to the Reformation. The BCP simplified older forms, and made the Bible itself the standard of all Christian worship.
The BCP contains in one volume what previously had been contained in many separate tomes: The Daily Offices (which are the Church's daily Morning Prayer and Evening Prayer), the Liturgy of the Holy Communion, the Ordinal (services for the ordinations of bishops, priests, and deacons), as well as many other services of the Church such as the Penitential Rite (used on Ash Wednesday), and the Baptism services.
In the face of new liturgical developments, including the discoveries of ancient texts, documents and practices in the 1970s, which brought about the use of the Book of Alternative Services (BAS) in Canada, thousands of Canadian Anglicans banded together to form a Society to preserve the traditions of Common Prayer in parishes across Canada. The Society is made up of clergy and laity within the Anglican Church of Canada, and is governed by a National Council made up of representatives from many dioceses in the Anglican Church of Canada. There are also local "Branches" and "Institutes" of the Society in many Canadian Dioceses.
The Prayer Book Society of Canada has sister organizations in Great Britain (under the patronage of Charles, Prince of Wales), The United States, and Australia, which share a common mandate and purpose. Prayer Book Societies around the world represent a broad spectrum of theological perspectives within Anglicanism. Members share a common desire to preserve the theological, liturgical and devotional tradition of Common Prayer within world-wide Anglicanism.
