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 ninth lecture in the series concerns itself with the non-canonical, or apocryphal gospels. Written before the discovery of the Nag-Hammadi library, this study considers the Testamentum Domini, Pistis Sophia, the Gospel and Apocalypse of St. Peter, the Protevangelium of James, the Infancy Gospel of Thomas, the Gospel According to the Hebrews, and the Oxyrhynchus Logia..
