... Devery S. Anderson has brought together a comprehensive collection of official documents on temple ceremonies, limited only by what would be inappropriate to discuss publicly. The documents include rulings by the First Presidency on changes to the ceremonies, letters to temple and stake presidents and bishops reminding them of temple policies, minutes of Quorum of the Twelve meetings, excerpts from sermons and Church publications, and commentary by apostles and temple presidents in diaries, letters, oral histories, and temple scrapbooks. Yes, the temple ceremonies have changed since their inception in Nauvoo in the 1840s. The liturgy was originally conveyed as a memorized, oral tradition, then in 1877 the leadership committed it to writing to guarantee consistency among several temples and facilitate changes they wanted to make at that time. This was repeated in 1922 when George F. Richards and a committee of apostles was charged with reviewing and rewriting the ceremoniesagain in the 1950s when the dramatic presentation was replaced with a motion picture and the script was shortened. One comes away from these documents with a better understanding of what constitutes the essence of the temple and what, by contrast, is malleable: staging, costumes, wording of the dramatic portions, and practical details such as whether marriage proxies should kiss across the altar.
