Testimonies about Jesus by known individuals were the raw materials of the gospels. Q consists of just over 200 verses, mostly sayings of Jesus, found in Matthew and in Luke but not in Mark, stemming from Jesus’s preaching tours around Galilee. This material manifests traits of oral transmission. It crystallized into fixed units, agglomerates, and written fragments through many retellings against the backdrop of communal memory of the outline of Jesus’s public ministry. It echoes themes of Mark.
