The Methodist Church has used a succession of hymnals (hymn books) and service books. The "Methodist Hymn-Book" (1933) was the first hymnal published after the 1932 union. In 1936 the church authorised the "Book of Offices", including an "Order for Morning Prayer", which closely copied the "Book of Common Prayer" (1662). Later, the "Methodist Service Book" (1975) modernised the language used in the Communion prayers; its widespread usage has been cited as a cause for increased frequency of Communion celebration in the Methodist Church. The publication of a new hymnal, "Hymns and Psalms" (1983), expanded the repertoire of 20th century compositions.
