The AUB has had a temple in Mexico since the 1990s, an endowment house in Utah since the early 1980s, and several other locations of worship to accommodate their members in the US states of Wyoming, Arizona, and Montana.

The title "Apostolic United Brethren" is not generally used by members, who prefer to call it "The Work," "The Priesthood," or "The Group."

The AUB furnished a detailed description of their beliefs and practices in August 2009 to the Utah Attorney General's "Polygamy Primer,"[2] which was later revised in 2011.

This can largely be attributed to the AUB's former prophet, Owen A. Allred, and his desire to be upfront with local law enforcement and the news media, especially when it came to ending rumors of underage, arranged marriages that many other fundamentalist Mormon groups were known for.

The AUB regards the Book of Mormon as sacred scripture in addition to the Bible, and accepts the Articles of Faith written by Joseph Smith to summarize Latter Day Saint beliefs.

While not all members take part in plural marriage, it is considered a crucial step in the quest for obtaining the highest glory of heaven.

He predicted in 1975 that "the time is at hand when God is going to intervene in the matter, and the temples will be opened to us, and we will have our endowments and do our own work for our dead."

Under his brother Owen's leadership, the AUB constructed its own endowment houses for ordinance work;[5] this was in response to the LDS Church's policy change which extended priesthood and temple blessings to all races, change which caused Allred to exclaim “do not go into a temple that has been defiled by the Canaanite being invited into it” and to publish an ad listing several racial statements from Brigham Young and accusing the LDS Church of forgetting past revelations.

Some of these doctrines include: Adam-God teachings; united order or "full consecration"; proper conferral of the priesthood; the ban on blacks receiving the priesthood; the doctrine of dissolution; the kingdom of God as a separate organization from the Church; the ordinance of rebaptism; the ordinance of mother’s blessings; giving a complete temple endowment (as opposed to the shortened version now administered in the LDS Church); the wearing of a full length, unaltered garment; the unchanging nature of all ordinances; prayer circles outside of the temple; and the law of adoption (sealing men to men as father/son).

The shooting of Rulon C. Allred by Rena Chynoweth on May 10, 1977 (under the direction of Ervil LeBaron), brought the AUB into the spotlight.

However, the dissident group and the main faction continued to jointly operate the private Pines Academy, which then had 129 students, as well as the municipal government.

[19] Rod Williams, a Secret Service agent involved in Watergate and a former member of the AUB, claimed in sworn testimony, as part of the Virginia Hill lawsuit, that he stole copies of LDS Church's temple ordinances from the Seattle Temple at the behest of Owen Allred, a claim denied by Allred.

[20][21] According to one former member, attorney John Llewellyn, "plural wives [of AUB men] are sent into nearby Hamilton to apply for welfare as single mothers.

"[5] In 2014, after Lynn A. Thompson assumed leadership of the AUB, he was accused of fondling his daughter Rosemary Williams when she was 12 years old,[22] and shortly thereafter two of his nieces also said he had sexually abused them too.
