I find it rather hard to believe that the true God would authorize such a temple ceremony as what was practiced by Mormons thru 1990...and also their previous temple ceremony practiced thru either 1926 or early 1927 -- where during the Mormon Temple Endowment, Mormons would swear the "Law of Vengeance Oath":
[This reconstruction of the endowment, which drew on various accounts of the ceremony, was published in 1931. The text appears to describe the pre-1927 endowment and thus was already outdated by the time it was published. The temple referred to in this text is the Salt Lake Temple].
Yes, the One True God forbade the swearing of ANY oaths, much less a vengeance oath.
It’s interesting that the oath was just removed from the service. An oath is binding... just telling people to stop saying it doesn’t relieve anyone from the obligations of oaths they already made. Did the Mormon church ever actually release anyone from the oaths they bound them with?
