John C. Poirier, in ‘The Roll, the Codex, the Wax Tablet and the Synoptic Problem’ ( JSNT 35.1: 3-30), argues that Synoptic source critics, particularly F. Gerald Downing and Robert A. Derrenbacker, Jr, have exaggerated and misrepresented the problems with Luke’s use of Matthew on the Farrer Hypothesis, as well as failed to consider the role that the medium of wax tablet may have played in Luke’s use of Matthew on that theory. However, in several areas, Poirier’s argument is problematic, misleading and in need of revision.
