It has been to bring together the historical evidences of the truth of this divine announcement that, in part, this work has been written; and therefore prominence has been given to those facts of history which support that announcement. But no fact has been suppressed that has a tendency to support the opposite view. No such fact either of history or prophecy exists. The whole stream of evidence proves that there has been a universal apostasy from the religion taught by Jesus Christ and his apostles; and the existing differences between the present teachings of "Christendom" and the doctrines of the scriptures is a proof so palpable that it admits of no contradiction. As this position of the church is one which the seventies and elders will have to maintain against all the world, it is of first importance that they become familiar with those facts of history and of prophecy that will enable them to maintain that position intelligently and successfully. The second purpose of the work is to teach the principles of the gospel. This, the author is convinced, can best be done in connection with their history. Relate the historical events which resulted in the introduction and establishment of the gospel and the church of Christ; then in all the centuries from the second to the tenth show how the doctrines of Messiah were departed from, how the ordinances were changed and the laws of God transgressed; relate the principal events of the sixteenth century revolution--miscalled the "Reformation"--and point out how that revolution, however salutary in bringing to pass an enlargement of popular liberty, failed to re-establish the gospel of the Lord Jesus Christ, or re-organize the church as at first founded by Messiah; then relate the events connected with the restoration of the gospel through the revelations given to the great prophet of the Dispensation of the Fullness of Times, Joseph Smith--and in so doing you are not only teaching the interesting facts of Ecclesiastical History to your students, but at the same time you are making them acquainted with the principles of the gospel. Under such a presentation the students, without being conscious of it, perhaps, will examine those principles under a variety of circumstances. They will see them stated in connection with the leading events of the Messiah's life; they will see them corrupted by an apostate church; they will hear them discussed by men during the attempt at Reformation; and after witnessing the unavailing efforts of the "Reformers" to re-establish the gospel and the church of Christ, they will see how the heavens were opened and every principle, doctrine, ordinance, law, officer and institution known to the church of Christ, restored. Such a presentation of the principles of the gospel, we repeat, must lead to a very comprehensive understanding of them, and such is one of the purposes of this work, and one which the author hopes will give it
