With all due respect, I was never a Christian before I was a Baha'i so I am not that familiar with the gospel accounts. We know that the gospel accounts are just stories written about Jesus long after Jesus walked the earth, so there is no way to verify that they ever transpired as recorded. I know the specific verses in Luke that refer to Jesus appearing and eating with the disciples and if they are true my best guess is that the Spirit of Jesus appeared to the disciples as a body to restore their faith in Him, although nobody can really prove that. But nobody can prove that the physical body of Jesus rose from the dead either so it is just a belief. Not all Christians believe it as can be seen on this website:
The resurrection of Jesus Christ Is it a fact or a religious myth?
For the sake of argument, even if the body of Jesus rose from the dead there are no verses in the Bible that state that Jesus ascended to heaven in the same body. Christians normally cite these verses:
.
Acts 1:10
And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; 11 Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
However, there is another explanation for what the angels saw in Acts 1:10-11. It was
the Christ Spirit that ascended, not a body, and that is what the angels saw. That makes perfect sense since angels can see spirits. Descending from heaven upon the clouds means that the spirit of Jesus, the Christ Spirit, will be made manifest from the heaven of the will of God and will appear in the form of the human temple. Though delivered from the womb of Mary, Jesus in reality descended from the heaven of the will of God, so Baha’u’llah descended
in like manner, from the heaven of the will of God.
