In 2011, the Joseph Smith Papers Project of The Church of Jesus Christ of Latter-day Saints made public a document created in 1835 by Orson Hyde and William E. McLellin. That document is presented in its entirety here with an introduction and editorial notes. Ronald Esplin and Sharon Nielsen, members of the editorial team of the Joseph Smith Papers, give historical context of the document: in 1835, twelve men were called as the Quorum of the Twelve Apostles. Joseph Smith instructed the quorum to keep a record of their meetings and actions; the document presented in this article is that record.
The Record of the Twelve contains minutes of the 1835 meeting in which the Twelve Apostles (Thomas B. Marsh, David W. Patten, Brigham Young, Heber C. Kimball, Orson Hyde, William E. McLellin, Parley P. Pratt, Luke Johnson, William Smith, Orson Pratt, John F. Boynton, and Lyman E. Johnson) were called. The Twelve were then sent on a mission to conduct conferences with branches of the Church in New York and New England in the summer of 1835. They preached and baptized along the way. This document tells of their trials and faith during their mission.
