Writing
Whitney produced the lyrics to several LDS Church hymns, including "The Wintry Day, Descending to Its Close" (music composed by Edward P. Kimball) and "Savior Redeemer of My Soul" (music by Harry A. Dean); these hymns appear as numbers 37 and 112, respectively, in the current edition of the LDS Church hymnal.
Whitney's historical works, although detailed, well researched and presented, are written from a Latter-day Saint perspective; one 21st-century historian has commented that they are "locked in the ironclad orthodoxy" of Mormonism.
In June 1888 (and published the following month in The Contributor), Whitney delivered a speech entitled "Home Literature"; the speech is widely credited with proving both permission and impetus for Mormon literature and is the source of the sentence, "We will yet have Miltons and Shakespeares of our own."
Whitney prepared a biography of Lorenzo Snow, a member of the Quorum of the Twelve, for publication in 1890. However it was not published at that time. It was entitled, Latter Leaves in the Life of Lorenzo Snow. In 2012, Dennis B. Horne published an edited and expanded version of this work under the same title with Cedar Fort, Inc., of Springville, Utah. This work covered the Snow's life from 1885 to 1889 and was written as a continuation of Snow's sister, Eliza R. Snow's, work Biography and Family Record of Lorenzo Snow. In publishing this work, Horne included Whitney's work as the first nine chapters of his book and then covered the following 11 years of Snow's life. Horne's published record only included about a third of Whitney's manuscript of his history of Lorenzo Snow.
