This classic by Harnack was an epoch-making historical work that set the standard for any history of doctrinal development. Harnack locates the origins and traces the development of the authoritative Christian doctrinal system from its beginnings down to the Reformation, with a brief survey of later developments through 1870.

This brief but thorough treatment of the history of the doctrines of Christianity starts out by showing what the structure of belief was that started with Jesus teachings and how that affected the teachings and spread of the Gospel from Jesus through the Apostles to the early catholic church. The next topic dealt with is the rise of one of the greatest heresies in the church, Gnosticism. Harnack is able to observe and lay out how the spread of the doctrines of the early church were able to create a breeding ground for the gnostic heresies and goes over the details of some of those heresies. This treatment of the early church is a valuable tool to any true scholar!

A History of Eastern Christianity (1968) is a scholarly and comprehensive account of the history of the non-Greek churches of Eastern Christendom. Alexandrine and Antiochian Christianity, with their ramifications in Africa and Asia, are the subjects of an overall survey that ranges from their origins to modern times. The author deals with every Eastern Church, Coptic, Ethiopian, Jacobite, Nestorian, Armenian, Indian and Maronite, as well as the vanished churches of Nubia and North Africa. He gives a preliminary outline of each church, followed by an analytical summary of the faith and culture. He deals not only with the hierarchy, rites, ceremonials and monastic rule, but also with music, art, architecture and literature.

History of Christian Dogma is a translation of Ferdinand Christian Baur's Lehrbuch der christlichen Dogmengeschichte, second edition, 1858. The Lehrbuch, which Baur himself prepared, summarizes in 400 pages his lectures on the history of Christian dogma, published post-humously in four volumes. Baur, professor of theology at the University of Tübingen from 1826 to 1860, brilliantly applied Hegelian categories to his historical studies in New Testament, church history, and history of Christian dogma. According to Baur, "Dogma" is the rational articulation of the Christian "idea" or principle-the idea that God and humanity are united through Christ and reconciled in the faith of the spiritual community. Following an introduction on the concept and history of the history of dogma, the Lehrbuch treats three main periods: the dogma of the ancient church or the substantiality of dogma; the dogma of the Middle Ages or the dogma of inwardly reflected consciousness; and dogma in the modern era or dogma and free self-consciousness. The entire history is a progression in the self-articulation of dogma through conflict and resolution, moving gradually from objective to subjective forms and to the mediation of subject and object by the philosophers and theologians of the early nineteenth century. The detailed analyses provide a wealth of information on individual thinkers and doctrines that is still relevant today.

Mesenteric-based gastrointestinal and colorectal surgery has been practiced internationally for over a century. However, it is not yet universally adopted, and considerable variations exist. Such variations are explained by the historical disparity that has persisted between anatomic and surgical approaches to the intestinal mesentery. While mesenteric-based surgery is far from new, it is remarkable that its anatomic basis has only recently been formally described. This means that key mesenteric principles of intestinal and colorectal surgery can now be taught, conducted and developed, in an entirely standardised manner. This book is composed of two parts. In this new book surgical anatomy, activities and operations are carefully defined, and beautifully illustrated, to enable all surgeons to conduct mesenteric-based intestinal and colorectal surgery, appropriately and with confidence.
