Did Mark and John independently share a source that covered the events that immediately lead up to Jesus’s crucifixion and the discovery of the empty tomb? Or did John read the narrative right out of Mark’s Gospel? We have been indirectly discussing this issue over the last month, but it brings to mind the wider question about the literary relationship between John’s Gospel and the other three “Synoptic” Gospels (Matthew, Mark, and Luke). Elizabeth Corsar has a fine summary about the history of scholarship on this question at the Centre for the Study of Christian Origins blog. Mark Goodacre is also the invited speaker on the topic of John’s knowledge of the Synoptic Gospels at the University of Oxford.
