I’m fortunate to be affiliated with a group of scholars at the Society of Biblical Literature. It is a program unit entitled: The Extent of Theological Diversity in Earliest Christianity. Here’s a description of its purpose:
The Extent of Theological Diversity in Earliest Christianity Group explores the origin, nature, and extent of theological diversity within Christian communities from the beginnings until approximately 180 CE. Focusing on the evidence for Jesus’ death and resurrection as a narrative used to shape the identity of emergent communities, as well as on the alternatives to this narrative preserved in early Christian sources, the unit seeks to clarify the historical origins and relationship of these diverse forms of Christianity and bring greater precision to the study of “orthodoxy and heresy in early Christianity.”
Although it is not quite up-to-date, the web address below will take you to some of the papers and activities of the group since its inception in 2008. There are papers there by Richard Bauckham, Birger Pearson, Todd Still, James Ware, Mark Goodacre and many others. More recently we have hosted sessions with Larry Hurtado, Bart Ehrman, and Judith Lieu. I’ll post the upcoming schedule for SBL 2016 in San Antonio.
