As reported by Canadian Press in newspapers on August 24, 1962:
The revision began in 1943. Publication of a draft work in 1955 produced a burst of controversy and prompted more than 1,200 letters to the committee from churches across Canada.The 1962 Book of Common Prayer is now mainly used by traditionalist Anglicans who have broken away from the Anglican Church of Canada because of the ACC's increasing liberalism. The Anglican Church of Canada published the Book of Alternative Services in 1985, and that's the main liturgical text in use by the ACC today.
...The book in general use now is a 1918 revision of the 1662 version.
The present revision, bringing some language and ideas up to date and reorganizing the layout for easier use by worshippers, also restores some liturgy from versions dating from the middle of the 16th century.
Two old anthems for use at communion have been revived from earlier versions in the new book.
The revised funeral service includes for the first time a place for reference to the deceased by name.
A discerning reader will see that "alternative" in the BAS's title really means "alternative to biblical Christianity."
