the book of prayers used at mass is called
Book of Common Prayer The Book of Common Prayer (BCP), originally The boke of the common praier and administracion of the sacramentes : and other rites and ceremonies of the Churche : after the use of the Churche of Englande, 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 Christian 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 (Careless 2003, p. 26).
Prayer of Saint Francis The anonymous text that is usually called the Prayer of Saint Francis (or Peace Prayer, or Simple Prayer for Peace, or Make Me an Instrument of Your Peace) is a widely known Christian prayer for peace. Often associated with the Italian Saint Francis of Assisi (c. 1182 – 1226), but entirely absent from his writings, the prayer in its present form has not been traced back further than 1912.[1] Its first known occurrence was in French, in a small spiritual magazine called La Clochette (The Little Bell), published by a Catholic Church organization in Paris named La Ligue de la Sainte-Messe (The League of the Holy Mass). The author's name was not given, although it may have been the founder of La Ligue, Father Esther Bouquerel. The prayer was heavily publicized during both World War I and World War II.[2] It has been frequently set to music by notable songwriters and quoted by prominent leaders, and its broadly inclusive language has found appeal with diverse faiths encouraging service to others.[1][3][4]
