As I searched online for some resources on oral tradition and the New Testament, I came across a couple of things that seemed to be worth sharing.
First, the site for a course on world religions called “The Sacred Journey” has several scholarly articles. Since most of the names were misspelled on that web page, I will reproduce them correctly here:
Gregory, Andrew. On oral and written Gospel? Reflections on remembering Jesus
Niditch, Susan. Oral Tradition and Biblical Scholarship
Kelber, Werner. Oral Tradition in Bible and New Testament Studies
Horsley, Richard. Oral Tradition in New Testament Studies
Hearon, Holly. The Implications of “Orality” for the Studies of the Biblical Text
There’s also the journal Oral Tradition which has its back issues available online. In fact, it is the source of a couple of the articles already mentioned. There are also relevant articles in the Bulletin of Biblical Research including one by Larry Hurtado on “Greco-Roman Textuality and the Gospel of Mark“.
Another piece by Holly Hearon, entitled “The Intersection of Contemporary Biblical Storytelling with Storytelling in the World of Antiquity: Invitation to a Conversation”, is but one of a number of interesting papers available on the site of the Seminar of the Network of Biblical Storytellers. There is also a piece by David Rhoads on this site, and another by him on “Performance Criticism” on the SBL site.
