As one of only three quadruply attested parables in the Gospel Tradition, the Mustard Seed describes the transformational growth of what Jesus calls the smallest of all the seeds. Season one’s final episode begins with a lighthearted quiz before moving on to examine the various differences between the story’s four extant versions. In the process of doing so Mark and Lee discover it is possible to understand the Mustard Seed both as a similitude and a parable proper with distinct meanings. Though reading the story as a parable proper presents readers with difficult existential challenges, Dr. Proctor prefers this approach on the grounds it enhances the story’s aesthetic and yields a more timely meaning for our contemporary situation.
