Sorry, this citation was related to Ehrman's view on Luke 24:51, but I omitted the connection...That was specific to Ehrman's decision about Luke 23:34. It hardly implies a wholesale embrace of his text-critical decisions. I disagree with him, for example, on his adjudication of the variant in Luke 24:51 --- I view the longer text as original to Luke's gospel whereas Ehrman takes the opposite position.
