I have mentioned the Jesus Seminar. There are other scholars of Christian origins who are not affiliated with the Jesus Seminar. You might be interested in following their work as well. Some of them have blogs for which I am grateful:
April DeConick blogs at The Forbidden Gospels Blog. She is a professor at Rice University and is interested in Christian literature that did not make it into the canon. She has written a fine book on The Gospel of Judas entitled The Thirteenth Apostle. She offers many fine posts on these other texts and on the difference between historical scholarship and theological scholarship.
James Tabor blogs at The Jesus Dynasty Blog. He is a professor at UNC-Charlotte and is interested in the Talpiot Tomb and has written a fine book, The Jesus Dynasty. He has special interest in James, the brother of Jesus, and the early Jesus movement.
James Crossley blogs at Earliest Christian History. He is a professor at the University of Sheffield in the U.K. He has written a fine book, Why Christianity Happened: A Sociohistorical Account of Christian Origins. He studies the earliest aspect of the Jesus movement to understand how the Christian movement began.
These are simply three that I check in with on occasion. There are certainly many others. These three are not affiliated with the Jesus Seminar as far as I know, and come to different conclusions.
The Jesus Project is an interesting endeavor. Their purpose "...is aiming at a probable reconstruction of the events that explain the beginning of Christianity." Shuck and Jive has the honor of being a related link. I look forward to their work.
Early Christian history is a hot topic these days. We questers are the beneficiaries.
