Joseph Smith (1805-1844), was the founding prophet of Mormonism. Smith claimed revelations and established his church in Manchester, Ontario County, New York (USA). Most of the early revelations were written for his followers. To understand Mormonism it is necessary to know something about its founder. His stories and revelations are the bases of this movement. From Smith comes the religious authority for all fragments of the Latter-day Saint movement. More importantly some of his commandments were revised and expanded. The emendations included reinterpretation of economic matters, adding offices that existed at the time of revision, and inserting references to priesthood restoration. Comparison with the second printing is included in the volume. Joseph Smith's 1828-1843 Revelations contains public and private revelatory documents from handwritten manuscripts, including the newly released Book of Commandments and Revelations. The Canadian copyright revelation, long rumored to be in existence, receives special attention. Two revelations on plural marriage are in the book. Joseph Smith made changes to his revelations and his early story. This book shows the transformation over time of church doctrine. H.
