In 1877, Elders James White and Uriah Smith gave a series of lectures on the principal doctrines of what Seventh-day Adventists teach and believe. These lectures were published the following year. This facsimile edition of these lectures once again offer a rare glimpse on the historic beliefs of the early pioneers. A thorough study of these all-important themes will help all who desire to acquaint themselves with a better understanding of what early Adventists taught and believed.
