No response to what I posted... again. So this is my last response.
I'm glad you quoted that passage. Early Christians did believe Jesus rose from the dead... in the spirit. Check 1 Peter for instance. Clement says the disciples were convinced. They were convinced, but why? Because of the empty tomb and a bodily resurrection? No. Because they had faith in him. You can't separate resurrection from bodily resurrection. Early Christians, however, believed, as in Hebrews, that Jesus passed immediately from the cross to heaven as a spirit when his body died. Thus the earthquakes and dead people rising in Matthew right when Jesus dies. Thus Jesus 'giving up the ghost' in Mark and John and even the Gospel of Peter
I disagree with you on the historical Jesus, and while I respect Bart Ehrman I think he's wrong on this. Go to thejesuspuzzle.com and read some of the articles, you're in for a surprise. I go for a more very minimalist position myself. For that I'd suggest Alfred Loisy, you can find his The Origins of the New Testament free at earlychristianwritings.com.
Final point: I used to believe what you do. There's a reason I don't anymore.
