Bar Hebraeus on Marcion

Most of it is pretty standard stuff but this line stood out to me "With regard to the Gospel he [Marcion] did not accept Luke and he says that the New Testament was given by the Good and the Old Testament by the Just to whom he [Marcion] gives the name Creator." [source] Notice that bar Hebraeus only says that Marcion REJECTED Luke not that he used a corrupt copy of Luke.  The idea that Marcion used Luke is stupid and can't possibly work given all the evidence.
