Mark has been at the center of debate about the nature of the Gospels and their relationships to one another. The history of Markan scholarship therefore offers a good overview of basic issues in the study of the Gospels. It also provides an orientation to different perspectives on the basic introductory questions: who wrote the Gospel, when, where, and why? Mark highlights Markan themes and makes numerous cross-references between related passages. The Gospel, moreover, remains one of the pillars of the Christian faith and tradition, one that is endlessly fascinating, inspiring, and pivotal for our understanding of Jesus.
