In some ways it seemed like his earthly body. But in other ways, it was definitely different. It was a body which was not subject to the usual laws of time and space. One might expect this confusion among Jesus' followers. After all, Jesus' resurrection was a unique, unprecedented event in their experience.
Christians ask another question.
The fact is that even Paul seems to give two different answers to this question. On one hand, Paul talks about a general resurrection of the dead, which will not take place until the end of time when Christ returns. We will not all die, but we will all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we will be changed. On the other hand, Paul also talks as though our resurrections will take place soon after our deaths, much as Jesus was resurrected shortly after his death.
