The Seventy’s Course in Theology (Second Year) / Outline History of the Dispensations of the Gospel [PDF ebook] 

The Seventy's Year Book No. II is a series of forty-four lessons on "The Outline History of the Dispensations of the Gospel." As our Year Book No. I was a rapid survey of the whole body of scriptures recognized by the Church, so the present Year Book is a like rapid, general survey of the principle dispensations of the Gospel given to men upon this earth. As the survey of the scripture books was made for the purpose of forming a general idea of the books as a body of sacred literature, and that some idea might be learned of their essential unity; so this present outline survey of the chief dispensations of the Gospel is intended to give some general views of the Gospel not otherwise obtainable, and to fix in the mind of the student the idea of essential unity in the Gospel in all dispensations: Establishing the idea that there is but one Gospel; and that, the "everlasting gospel;" the same through all ages. That it was the plan devised in heaven before the foundations of the earth were laid, and will endure as a means of salvation so long as there are men to be saved.
The Treatment of the Theme: The treatment of the theme is substantially the same as in Year Book No. I. That is to say, an analysis of the subject of the lesson is given, in which the lesson is subdivided under those heads into which the subject naturally falls. For the information, of the student texts and books are cited accompanying usually each subdivision of the subject and these references in every case should be carefully read so far as the books cited can be obtained by the student; and as the books to which citations in the main are made, the four books recognized by the Church as Holy Scripture, each Seventy student should have these. Accompanying each lesson are a series of notes, sometimes detached, but often, in this Year Book, they constitute a brief continuous treatise upon the subject in hand, which should be amplified by wide reading and deep study on the part of the student. In all cases where no citation of authorities is given at the close or in the body of the note, they are written by the compiler and editor or are taken from his works.
