Context paragraphs:
Ensign (LDS magazine): The Ensign of The Church of Jesus Christ of Latter-day Saints, commonly shortened to Ensign , is an official periodical of The Church of Jesus Christ of Latter-day Saints (LDS Church).  The magazine was first issued in January 1971 along with the correlated "New Era" (for youth) and the "Friend" (for children), all of which replaced the older church publications "Improvement Era", "Relief Society Magazine", "The Instructor", and the "Millennial Star".  Unlike some of its predecessors, the "Ensign" contains no advertisements.

Kirtland Temple Suit: The Kirtland Temple Suit (formally Reorganized Church of Jesus Christ of Latter Day Saints v. Williams) is an 1880 Ohio legal case that is often cited as the case that awarded ownership of the Kirtland Temple to the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church).  Though the case was dismissed by the court, the publication of the court's findings of fact—as if they had been the decision of the court—reinforced the belief by members of the RLDS Church and others that the court had considered the RLDS Church, and not The Church of Jesus Christ of Latter-day Saints (LDS Church), the rightful legal successor to the Latter Day Saint church established by Joseph Smith in 1830.

Thomas B. Marsh: Thomas Baldwin Marsh (November 1, 1800 – January 1866) was an early leader in the Latter-day Saint movement and an original member of the Quorum of the Twelve Apostles.  He served as the first President of the Quorum of the Twelve Apostles of the Church of Jesus Christ of Latter-day Saints from 1835 to 1839.  He was excommunicated from the church in 1839, and remained disaffected for almost 18 years.  Marsh was rebaptized into The Church of Jesus Christ of Latter-day Saints (LDS Church) in July 1857, but never again served in church leadership positions.

First Presidency: Among many churches in the Latter Day Saint movement, the First Presidency (also known as the Quorum of the Presidency of the Church) is the highest presiding or governing body.  Present-day denominations of the movement led by a First Presidency include The Church of Jesus Christ of Latter-day Saints (LDS Church), the Community of Christ, Remnant Church of Jesus Christ of Latter Day Saints.  and the Righteous Branch of the Church of Jesus Christ of Latter-Day Saints.

History of the Church (Joseph Smith): History of the Church (cited as HC) (originally entitled History of Joseph Smith; first published under the title History of the Church of Jesus Christ of Latter-day Saints; nicknamed Documentary History of the Church or DHC) is a semi-official history of the early Latter Day Saint movement during the lifetime of founder Joseph Smith.  It is largely composed of Smith's writings and interpolations and editorial comments by Smith's secretaries, scribes, and after Smith's death, historians of The Church of Jesus Christ of Latter-day Saints (LDS Church).  The history was written between 1839 and 1856 .  Part of it was published in "Times and Seasons" and other church periodicals.  It was later published in its entirety with extensive annotations and edits by B. H. Roberts as part of a seven-volume series beginning in 1902 as "History of the Church of Jesus Christ of Latter-day Saints".

Latter Day Saint movement: The Latter Day Saint movement (also called the LDS movement, LDS restorationist movement, or Smith–Rigdon movement) is the collection of independent church groups that trace their origins to a Christian primitivist movement founded by Joseph Smith in the late 1820s.  Collectively, these churches have over 15 million members.  The vast majority of adherents belong to The Church of Jesus Christ of Latter-day Saints (LDS Church), with their predominant theology being Mormonism.  The LDS Church self-identifies as Christian.  A minority of Latter Day Saint adherents, such as members of the Community of Christ, believe in traditional Protestant theology, and have distanced themselves from some of the distinctive doctrines of Mormonism.  Other groups include the Remnant Church of Jesus Christ of Latter Day Saints, which supports lineal succession of leadership from Smith's descendants, and the more controversial Fundamentalist Church of Jesus Christ of Latter-Day Saints, which defends the practice of polygamy.

Children's Songbook: The Children's Songbook of The Church of Jesus Christ of Latter-day Saints is the official songbook for children in The Church of Jesus Christ of Latter-day Saints (LDS Church).  It was first published in English in 1989.  These songs are for the Primary, which is an organization in the LDS Church for children between the ages of 18 months and 12 years old, who learn about the teachings of Jesus Christ.

Bon Appétit: Bon Appétit is an American food and entertaining magazine published monthly by Condé Nast.  It was started in 1956.  It became a bimonthly magazine in December 1956 in Chicago.  The magazine was acquired by M. Frank Jones in Kansas City, Missouri in 1965.  Jones was owner, editor and publisher until 1970, when "Bon Appétit" was merged into the Pillsbury Company, who sold it to Knapp Communications, publishers of "Architectural Digest", four years later.  Condé Nast Publications, the current owners, purchased Knapp Communications in 1993.  Its sister publication was "Gourmet", before the latter was discontinued in October 2009.  The magazine's headquarters, which had been in Los Angeles, CA, were moved to New York City in early 2011.

Temple (Latter Day Saints): In the Latter Day Saint movement, a temple is a building dedicated to be a house of God and is reserved for special forms of worship.  A temple differs from a church meetinghouse, which is used for weekly worship services.  Temples have been a significant part of the Latter Day Saint movement since early in its inception.  Today, temples are operated by several Latter Day Saint denominations.  The most prolific builder of temples of the Latter Day Saint movement is The Church of Jesus Christ of Latter-day Saints (LDS Church).  There are 157 operating temples (which includes 2 previously dedicated, but closed for renovation), 12 under construction, and 13 announced (not yet under construction).  Several other variations of the church have built or attempted to build temples.  The Community of Christ operates two temples in the United States, which are open to the public and are used for worship services, performances, and religious education.  Other denominations with temples are the Apostolic United Brethren, the Church of Christ, the Fundamentalist Church of Jesus Christ of Latter-Day Saints and the Righteous Branch of the Church of Jesus Christ of Latter-day Saints.

Origin of Latter Day Saint polygamy: Polygamy, or plural marriage, in the Church of Jesus Christ of Latter Day Saints probably originated with the founder of Mormonism, Joseph Smith, who taught that polygamy was a divine commandment.  Smith practiced it personally, by some accounts marrying more than 30 women some of whom had existing marriages to other men.  Evidence for Smith's position is provided by the church's "sealing" records, public marriage licenses (in many cases notarized), affidavits, letters, and journals and diaries; however, until his death, Smith and the leading church quorums denied that he preached or practiced polygamy.  Smith's son Joseph Smith III, his widow Emma Smith, and the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church, now called the Community of Christ) challenged the evidence and taught that Joseph Smith had opposed polygamy.  They instead claimed that Brigham Young, the head of The Church of Jesus Christ of Latter-day Saints (LDS Church), introduced plural marriage after Smith's death.  In 1852, leaders of the Utah-based LDS Church acknowledged that Smith taught and practiced polygamy.
