In 1979, a more substantial revision was made under the influence of the Liturgical Movement. Its most distinctive feature may be the presentation of two rites for the Holy Eucharist and for Morning and Evening Prayer. The Rite I services keep most of the language of the 1928 and older books, while Rite II uses contemporary language and offers a mixture of newly composed texts, some adapted from the older forms, and some borrowed from other sources, notably Byzantine rites. The Book also offers changed rubrics and the shapes of the services, which were generally made for both the traditional and contemporary language versions.
