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).
Latin Mass A further distancing between the concepts of "Tridentine Mass" and "Latin Mass" was brought about by the 1964 Instruction on implementing the Constitution on Sacred Liturgy of the Second Vatican Council, which laid down that "normally the epistle and gospel from the Mass of the day shall be read in the vernacular". Episcopal conferences were to decide, with the consent of the Holy See, what other parts, if any, of the Mass were to be celebrated in the vernacular.[3] Permissions were thus granted from 1967 onwards to celebrate most of the Tridentine Mass in vernacular languages, including the Canon.
