A scribal error has turned up in Q! This has wide-ranging implications and consequences, to which the present paper is designed to point. If there is a scribal error in Q, then Q was indeed a written Greek text, behind which stood an older written Greek text as Vorlage. This, of course, finally puts to rest already outdated theories of Q being only an Aramaic text, or only a layer of oral tradition rather than a written text. It also has important implications for the current view of Q and points into the future of pre-Q research as well. The history of the synoptic tradition is no longer dependent only on the forms of oral transmission, but now has a series of written texts bridging much of the gulf back from the canonical gospels to Jesus.
