The work is divided into four parts, each with a distinct idea running through it. Part I deals with THE ESTABLISHMENT OF THE CHURCH through the ministry of Messiah and his apostles; Part II with THE APOSTASY, brought about through the severe persecution to which the early saints were subjected, the rise of false teachers, changing the ordinances of the gospel, intermingling pagan philosophy with Christian doctrine, and a transgression of the laws of God; Part III deals with "THE REFORMATION," treating it, however as a revolution instead of a reformation since the so-called reformation by no means re-established primitive Christianity, either in its form or essence, but it did overthrow the power of the Catholic Church in the greater part of Western Europe, gave larger liberty to the people, and thus prepared the way for the great work which followed it—the introduction of the Dispensation of the Fullness of Times; Part IV treats of THE RESTORATION OF THE GOSPEL, in the aforesaid dispensation, through the revelations which God gave to the Prophet Joseph Smith.
