As far as I am concerned these are just stories that the gospel authors told, fictional stories. I know I am not to convince any Christian of that as people are going to believe what they believe, but these are not historical facts, they are stories. The missing body is just part of the story, and no story is proof that the story is actually true. Of course it is written to sound true, but that does not mean it is true. The point is that nobody can ever prove it ever happened.
No, that is not what Paul taught. He did not teach that the physical flesh would be transformed into a physical body that will never die. A physical body cannot be changed into a body that will never die. Rather, there are two different kinds of bodies, as Paul said:
--- The glory of the heavenly bodies is
different from the glory of the earthly bodies.
--- For just as there are natural bodies, there are
also spiritual bodies.
Our physical bodies will die and we will be raised as spiritual bodies. Paul says that our physical bodies cannot inherit the Kingdom of God and that means they cannot exist in heaven. When Paul says these dying bodies cannot inherit what will last forever, he is referring to the spiritual world (heaven), which will last forever.
In case you are not aware of this there are many liberal Christians who do not believe that Jesus rise from the dead.
What many liberal theologians believe about Jesus' death
The resurrection has nothing to do with whether Jesus came in the flesh or not. My religion clearly teaches that Jesus came in the flesh.
It does not include that and the two are not linked in the Bible.
We must believe that Jesus was born in the flesh, lived in the flesh, and died in the flesh, but we are not required to believe that the physical body of Jesus came back to life after three days. There is no reason to believe such a thing, except for stories men wrote
about Jesus, men who never even knew Jesus. Nowhere did Jesus ever say He rose in the flesh. I will allow the atheists to explain all the contradictions in the gospels of accounts of the resurrection because they are more familiar with the Bible than I am.
