First, Craig, thanks for these 3 update posts.

Steven: Alas, you misstate the point of what we should look for, I think. 1 Cor 15 does not mention merely flesh and blood because the spiritual body referred to is not a mere repeat of mortal flesh and blood. More importantly, the implication you make ignores the fact that in Judaism the kind of resurrection that was expected was a bodily one in most cases (Just read 2 Macc 7 and see how physical a dimension there was to this hope). So Paul did not need to detail what resurrection involved in terms of physicality because they knew. If you doubt this, just look at how physical the Sadducees who ask Jesus about resurrection see it. Jesus replies the resurrection body is like an angel (again pointing to a difference of which the Sadducees are ignorant, but with physicality involved).
