Of the many tensions characterizing the Gospel of John, one of its perplexities most needing to be addressed critically is the set of issues related to aspects of historicity.1 On one hand, John is the most spiritual, theological, and symbolic of the canonical Gospels, leading scholars in recent decades to take seriously the literary features of the work. On the other hand, there is more archaeological, topographical, and apparently historical material in John than in any other Gospel, or even in all three combined.
