The identity of the “leaven of the Pharisees”[1] provides us with an excellent example of the Synoptic Problem. Each of the Synoptic Gospels—Matthew, Mark and Luke—records a saying of Jesus in which he warns his disciples against the “leaven of the Pharisees,” but each Gospel identifies this leaven differently. Matthew identifies the leaven as “teaching” (Matt. 16:12). Mark does not explicitly state what the leaven is, but has Jesus chide his disciples for not understanding what he is referring to (Mark 8:17, 21). Luke identifies the leaven as “hypocrisy” (Luke 12:1).
The theory of Markan Priority can account for these different identifications in the following manner: using Mark as their source, the authors of Matthew and Luke each supplied identifications of the “leaven of the Pharisees,” which had been left unidentified in Mark. Because the authors of Matthew and Luke worked independently of one another, the two authors came up with different identifications. Matthew identified the leaven as teaching, whereas Luke identified the leaven as hypocrisy.
While the account supplied by the “Mark first” model seems simple and straightforward, it does not yield much insight into what the author of Mark wished to signify by the leaven of the Pharisees. Neither does it explain why, whereas in Luke Jesus gives a simple warning (Luke 12:1), in Mark and Matthew there is a comparatively lengthy exchange between Jesus and the disciples on the identity of the leaven (Mark 8:14-21; Matt. 16:5-12). Nor does it explain the strange agreements between the Lukan and Matthean versions of Jesus’ warning, which suggest that behind Luke and Matthew there lies a non-Markan source. We believe that a different synoptic model, namely that which Robert Lindsey championed, can yield greater insight into the “leaven of the Pharisees.” Lindsey believed that Mark was not the first of the Synoptic Gospels, but the man in the middle.[2] According to Lindsey, the author of Mark used Luke’s Gospel as a source, while the Gospel of Matthew relied upon Mark. But the author of Matthew also had access to one of Luke’s sources, which explains how Luke and Matthew could sometimes agree against Mark. Since we believe Lindsey’s hypothesis may hold the answers to the identity of the leaven of the Pharisees, it is his model that we will use as we pursue our investigation.

Conclusion
Whether or not we have successfully recovered the original meaning of Jesus’ warning against the leaven of the Pharisees, the application of Lindsey’s hypothesis to this pericope has yielded fascinating results. We have discovered a common non-Markan source behind the versions of Jesus’ warning in Luke and Matthew. We have solved the riddle of Mark’s identification of the leaven. And we have caught a glimpse of the methods by which the authors of Luke, Mark and Matthew edited their sources and compiled their Gospels.
