I'm still planning to blog my way through the Christology of Mark's Gospel, but I haven't managed to do so yet. And so, in the meantime, here's a round-up of the blogging on that topic that has taken place since the last time I posted on this topic:
The Jesus Blog had several posts on the topic, including one on whether Markan Christology is “low, underdeveloped, or understated,” another on whether Christology is the best category to use in this discussion, and a question posed to James Crossley by a blog reader.
Matthew Montonini asked whether the divinity of Jesus in Mark is in the eye of the beholder rather than what the text explicitly says. And yet in another post today he argues that Mark depicts Jesus' pronouncement of forgiveness of sin to imply his divinity (ignoring the fact that the Gospel of Matthew, Mark's earliest interpreter, does not understand it that way).
I hope the above will provide you with enough to tide you over until I get around to blogging my way through the Christology of the Gospel of Mark myself here on this blog!
