Originally delivered as one of the Jowett Lectures for 1906, the contents of this booklet emerged during the first quest for the historical Jesus. Somewhat surprisingly, Burkitt discovered that historical criticism increased the historical credibility of the Synoptic Gospels in his estimation. This sixth lecture in the series turns to the Gospel of John. Burkitt addresses the enduring questions of authorship and historicity, comparing the Gospel of John to the Synoptics, Philo, the Gnostics, and the Stoics.
