Most of the scholarship I've read on Mark seems to agree that for him, Jesus's baptism was the important Christological moment, i.e. the moment that Jesus became Christ as the Spirit descended on him. OTOH, the ending of Mark remains a puzzle: why does Jesus cry from the cross that God has abandoned him? It seems to me that the logical solution is that the cry from the cross was (for Mark) the moment that the Spirit left Jesus. That is, Mark has a sort of docetic Christology in which Jesus was possessed by the Spirit during his ministry. The Spirit then left him just before his death. Some partial support for this idea comes from an early writer (Eusebius? Irenaeus? I forget.) who notes that Mark was the gospel of choice for the Docetists. Also, it helps explain some of the puzzling aspects of Mark's gospel, e.g. why the demons recognize Jesus as Christ even when his own disciples don't - they are both the same sort of being. The (evil) spirit in the demon-possessed person recognizes the (Holy) Spirit in Jesus. I've never seen this idea mentioned in any of the scholarship I've read, though. Does anyone know if this has ever been suggested? Or if there is any reason (other than prejudice against the earliest gospel being a "heretical" one) to reject it?
