Even in the relatively short span of years I've been a temple-attending adult, there have been changes to the temple ceremony. I've wondered, to what extent do the current rites, oaths, covenants, and other aspects of the ceremony reflect the endowment as it would have been experienced by early saints in Nauvoo? This scholarly work documents the evolution of the endowment experience and the dwindling significance of other temple ordinances, such as the Second Anointing (once taught to be an essential ordinance to exaltation)and the Law of Adoption (by which a man of lower status was sealed eternally to a man of greater prominence.)
In his dispassionate, scholarly treatment of the subject, Buerger is punctilious about avoiding the sensational. Anyone looking for an exposé should look elsewhere, because this is a serious treatment by a serious historian. Similarly, anyone looking for a devotional treatment of the subject, or who believes that the modern ceremony's origins are ancient and that every ritualistic detail has been preserved with perfect fidelity, should first ask themselves if they are prepared to read a book like this.
The influence of freemasonry on the endowment is handled fairly, but more interesting are the internal deliberations by church leaders advocating or resisting changes in policy and ritual:
At least some changes seem to have occurred in response to societal pressures; for example, after the Reed Smoot senate hearings disclosed that temple initiates in that day were made to take an oath of retribution against the nation for spilling the blood of the prophet, the oath--and any mention of retribution--was stricken from the language of the ceremony. Another change that seems to have arisen from changing sensibilities eliminated the graphic description of penalties such as throat-cutting and disembowelment (changed in 1920s) and the related symbolic gestures of those self-inflicted penalties.(1990). The latter change was one of several changes made to the ceremony in 1990, informed by the results of a survey the Church sent out to over 3000 endowed members asking what aspects of the temple they found uncomfortable or distasteful.
I found it fascinating how church leaders solved new challenges by thinking "outside the box," such as when a young Gordon B. Hinckley proposed a plan to use film as a medium for presenting the endowment. One film in the 60s fell in disfavor with President Lee because a few of the actors had beards and long hair. A new film was commissioned.
Policies governing who would recommend couples to receive their Second Anointing changed as church membership soared. At one point, Stake Presidents were told not to send more than one couple to the temple from their stake per Sunday (the day designated for the ordinance), to avoid the embarrassment at being recognized.
Most fascinating were the contemporaneous accounts of the those who attended the Kirtland temple (prior to a ritualistic ordinance)in a spirit of worship. The pentecostal fervor of those Saints would be so incongruous in modern temple worship, where a subdued spirit of restraint prevails to the point that some find themselves pondering the solemnities of eternity from behind closed lids.
I don't think other temple-attending Latter-day Saint would find this book's treatment of the temple disrespectful in any way. Knowing that significant changes have occurred in the past may prepare a younger generation to accept future changes that will inevitably come. For a non-Mormon, the book might be an interesting and credible vantage from which to view the origins and development of the temple ceremony, since few members (myself included) are even remotely acquainted with the historical facts; moreover, members sometimes extend the few prohibitions against disclosing particulars to an excessive secrecy about the entire ceremony. In my view, this lack of openness, where permitted, generates only mistrust and alienation.
The generosity of information offered by this book gives me a greater sense of perspective and a deepened sense of tradition to bring to bear in my temple worship.
