Wentworth Letter

The "Wentworth letter" was a letter written in 1842 by Latter Day Saint movement founder Joseph Smith to "Long" John Wentworth, editor and proprietor of the Chicago Democrat. It outlined the history of the Latter Day Saint movement up to that time, and included Mormonism's Articles of Faith.

The letter was written in response to Wentworth's inquiry on behalf of one of his friends, George Barstow, who was writing a history of New Hampshire. The letter was first published on March 1, 1842, in the Times and Seasons in Nauvoo, Illinois.

A similar letter (with some slight revisions) was published by Daniel Rupp in 1844 in a book called An Original History of the Religious Denominations at Present Existing in the United States.

First, it connects the message of what Mormons believe to be the Restoration with the history of said Restoration: "By these things we know..." (Doctrine and Covenants 20:1-17)

Second, it emphasizes the First Vision as an essential part of Latter-day Saint message.

Third, it contains the Standard of Truth, a mission statement for missionaries:

Fourth, it ends with the statements which later became the Articles of Faith. B. H. Roberts said of these,
