Fairkatrina, he was also stabbed in the side with a spear. I have problems with physical resurrection, certainly, but I don't think there can be much doubt that he was dead before he was laid to rest. You try hanging there for six hours struggling to breathe and then having a nice, blunt iron spear thrust into your vitals - and the Romans weren't stupid, they knew all about crucifixion, they practised it regularly, and they wouldn't have allowed him to be taken away without being dead.
I am a regular church-goer and a strong believer in the doctrines of Christianity - basically, do as you would be done by - but I do have a problem with virgin birth and physical resurrection. Doesn't make me less of a Christian though, so I'm told!
