Q is a hypothetical entity, part of the standard solution to the Synoptic Problem - the study of the inter-relationship of Matthew, Mark and Luke. This solution supposes that Matthew and Luke made independent use not only of Mark but also another source - now lost - called 'Q'. Belief in its existence is commonplace, but there have always been doubters. Mark Goodacre is one of them. In The Case Against Q, Goodacre presents a careful, balanced and detailed critque of the Q hypothesis, examining the most important arguments of Q's proponents. He offers new arguments and fresh reflections, creating a more plausible picture of Synoptic relationships than has ever been available.
