You have to keep an eye on Mark Goodacre. He’s been dating again, in preparation for his SBL paper (with April DeConick as respondent). Check out his series so far:
(I) Preliminary Remarks
(II) Paul’s Letters
(III) Synoptic Gospels (Order of)
(IV) John’s Gospel
(V) Mark’s Gospel
(VI) Mark’s Gospel (continued)
(VII) Matthew and Luke’s Gospels
(VIII) John and Thomas’ Gospels
It should be a good discussion. Simon Gathercole, Stephen Patterson, and John Kloppenborg will be involved in the session as well.
UPDATE: Mark’s SBL paper is now available here.
