What does it mean to read the gospels “before the book”? For centuries, the way people have talked about the gospels has been shaped by ideas that have more to do with the printing press and modern notions of the author than they do with ancient writing and reading practices. Gospels Before the Book challenges several subtle yet problematic assumptions about authors, books, and publication at work in early Christian studies. The author explores a host of underappreciated elements of ancient textual culture, such as unfinished texts, accidental publication, postpublication revision, and multiple authorized versions of the same work. Turning to the gospels, he argues the earliest readers and users of the text we now call the Gospel according to Mark treated it not as a book published by an author but as an unfinished, open, and fluid collection of notes (hypomnēmata). The Gospel according to Matthew, then, would not be regarded as a separate book published by a different author but, rather, as a continuation of the same unfinished gospel tradition. Similarly, it is not the case that, of the five different endings in the textual tradition, one is “right” and the others are “wrong.” Rather, each ending represents its own effort to fill in what some perceived to be lacking in the Gospel according to Mark. The text of the Gospel according to Mark is better understood when approached as unfinished notes than as a book published by an author. Larsen also offers a new methodological framework for future scholarship on early Christian gospels.
