In this groundbreaking book, preeminent Q scholar and founding co-director of the International Q Project John Kloppenborg traces the literary evolution of Q as a document of primitive Christianity by considering it within the context of ancient literary genres. By carefully identifying the distinct influences of wisdom instruction, prophetic literature, and proto-biography, together with penetrating syntactical and rhetorical insights, Kloppenborg is able to present a compelling case for the compositional stages of this elusive source document for the Gospels of Matthew and Luke.
