Abstract: Here I address specific criticisms of Margaret Barker’s work. First, I set the stage by discussing Thomas Kuhn’s The Structure of Scientific Revolutions as a map and compass for navigating this kind of controversy. I show how his observations cast light on debates about Jesus in the Gospel of John, which in turn resemble present debates. In this context, I then consider some notable criticisms of Barker’s work as “not mainstream” and consider an instructive appreciation of Barker by Father John McDade in his “Life of Jesus Research.” I then respond in detail to a recent BYU Studies essay that was critical of Barker’s work.
