The Q hypothesis has functioned as a mainstay of study of the synoptic gospels for many years. Increasingly it comes under fire. In this volume leading proponents of Q, as well as of the case against Q, offer the latest arguments based on the latest research into this literary conundrum. The contributors to the volume include John Kloppenborg, Christopher Tuckett, Clare Rothschild, Mark Goodacre, and Francis Watson. The Q hypothesis is examined in depth and the discussion moves back and forth over Q's strengths and weaknesses. As such the volume sheds light on how the gospels were composed, and how we can view them in their final literary forms.
