Recently reconstructed by scholars, Q is one of the New Testament's earliest source documents. Arguing that Q's participation in the apocalyptic worldview of late Second Temple Judaism has greater consequences for its compositional history than previously recognized, Olegs Andrejevs performs a new literary-critical, narrative, and philological analysis of a number of Q passages, supplementing it with recent advances made in the study of Jewish apocalyptic literature, particularly the Enochic book of Parables and Qumran wisdom documents 4QInstruction and 1Q/4QMysteries. The end result is an updated stratigraphic model which synthesizes the insights of several scholars, most notably John S. Kloppenborg and Dale C. Allison, Jr., and highlights the feasibility of Q's diachronic study.
