(The Mormons also believe that spirits have flesh bodies in heaven.)
Hi Blondie,
As far as I know, in mainstream Christian doctrine, Jesus is so far unique in that he is the only one with a glorified human body....(until the resurrection at the rapture). Then, "we shall be like him." & "meet him in the air".
The three main doctrines in Christianity are: 1. Justification (covered by the blood to be legally righteous) 2. Sanctification (set apart for the purposes of God) & 3. Glorification (having a glorified body like Jesus.)
When asked if his body was really him, Jesus invited others to touch him and reassured them that an apparition (spirit) could not be touched like he could. He went into heaven in front of hundreds in this same body. Angels asked, "men of Galilee, why do you stare into heaven? Do you not know that THIS SAME JESUS, will return in like manner."
The glorification of the human body; ie. gaining extra capabilities of which immortality is not the least, is bedrock Christian doctrine since the times of the apostles. Having a glorified, supernatural, yet real flesh and blood body - forever, is characterized as "the blessed hope" in Titus 2: 13 that will realized at Jesus glorious appearing. This is THE HOPE of Christians, whether they are now in the body, or already out of the body with Jesus.
Your word choice makes it sound like this is a fringe doctrine, In reality, it has been the hope of most every born-again Christian for the past 2000 years. Not only are Christians expecting God to reverse the effects of sin that none of us asked to inherit; they are also expecting God to make good on his promise to glorify them.... make them even better than perfect Adam & Eve was.
