This welcome edition of Carl Richard Schenkel's 1899/1900 notes from Adolf Harnack's introductory lectures to the New Testament makes publicly accessible for the first time a transcript of Harnack's university lectures. The present edition includes a full transcription of Schenkel's notes, brief afterword and indices. The lecture course itself is divided into two parts: the historical emergence of the New Testament canon and the history of the individual books, which represent, for Harnack, the two principal questions for New Testament research. In the first part, readers will find an outline of Harnack's account of the formation of the New Testament canon that, unsurprisingly, gives significance to the controversies of second-century Gnosticism. In the second part, there is a more intensive presentation of Harnack's quasi-scholastic hypothetical method of inquiry regarding the formation of the individual books of the New Testament. Here readers will find most of the explicit references to Harnack's disagreements with other scholars, such as Baur, Weiss, Renan and Jülicher. Those familiar with Harnack's New Testament research will not be surprised to find his characteristic mixture of traditionalism and radical conjectural criticism present throughout the two parts of his lecture course. In general, the text admirably organises the initially handwritten notes in a clear format, making only one typographical error in the printed Greek (p. 22). As the editors note, this edition will be significant for anyone interested in Harnack's Wirkungs and Bildungs historical perspective, especially as it indicates the reception of Harnack's academic teaching. But in addition to offering a privileged snapshot of the celebrated church historian's pedagogy, the lectures provide the possibility of exploring the state of Harnack's New Testament research at the turn of the nineteenth and twentieth century, and may even prove to illuminate the development of his famous lectures Das Wesen des Christentums. Harnack the New Testament scholar is often obscured by the more prominent (and thus more exhaustively studied) historian of doctrine and public intellectual. But as more of Harnack's oeuvre becomes publicly available, perhaps it will become clearer how Harnack the New Testament scholar and Harnack the historian and public intellectual offer a unified view of religious scholarship in the early twentieth-century German university.
