While it is almost universally recognized that Matthew and Luke used Mark as their prime source of information for their respective gospels, it is also well recognized that Matthew and Luke frequently add to, omit or change details present in Mark’s source story, occasionally in significant ways. This is largely attributed to Matthew and Luke editing Mark to fit their respective theological agendas. Yet, when stories in John appear to intersect with stories in the synoptic gospels, John is rarely accorded the same privilege.
While there is obviously a vast library of writings describing John’s theology and how it might differ from the synoptic gospels, there appears to be almost no effort to apply John’s theological principles to any of the synoptic gospels, using the theology as a filter for examining what changes John would likely have made if he knew the story. While there may be an isolated comparison between a Johannine story and a synoptic story here and there, I believe The Case for a Proto-Gospel presents the first scholarly study to provide a full-scale systemic look at all of John and how his theological principles interact with the synoptic gospel stories.
In this post, I will outline how John’s theological concerns can function as a filter for reading the synoptic gospels, which enables us to identify theological problems that would bother John and require corrections if he were to edit the synoptic story. In the next post, I’ll identify some of the editorial techniques John used to make these corrections. In subsequent posts, I’ll examine various synoptic stories and show how John’s theology and editorial practice come together to transform synoptic stories into Johannine versions that share the same underlying story elements present in the synoptic story but which often looks so different from the synoptic story.
