公祷书（The Book of Common Prayer）是圣公会的礼文书，同时也是普世圣公宗和各成员教会的宪法。圣公会经过与罗马天主教的分裂，在神学、崇拜礼仪等方面有重大的改变。16世纪改革初期陆续推出了一些信纲，如《三十九条信纲》, 但是因为圣公会受到英美法系的影响，并不使用成条文的信纲作为依据，因此这些信纲很快就不被使用，而是通过统一的《公祷书》规范教会的活动和组织，进而作为评判信仰的基本原则。公祷书也是指导解读《圣经》的基本原则，在神学上类似信义宗的《协和信纲》。

The Book of Common Prayer 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 (Church of England 1957), 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 (Careless 2003, p. 26).
