The bodies that Paul is talking about in vs 40-42 are the bodies that will rise with us in the resurrection. This section of 1 Corinthians 15 is about the resurrection.
Paul says that there will be celestial bodies that are comparable to the glory of the sun.
Paul says that there will be terrestrial bodies that are comparable to the glory of the moon.
And Paul says that there will be bodies that will be comparable to the glory of the stars, but does not give a name for these bodies. JS was told that the name of these bodies will be Telestial.
In this section on the resurrection Paul would not be talking about the resurrection of the planets, sun, moon and stars (celestial), or the resurrection of the beasts, fish, earth (terrestrial). But he is talking about the resurrection of men's mortal bodies.
This is an insight into the 3 heavens that LDS talk about. The people that are resurrected into the highest heaven will have celestial bodies, comparable to the glory of the sun.
Those who are resurrected into the next highest heaven will have terrestrial bodies, comparable to the glory of the moon.
Those who are resurrected into the next highest heaven will have telestial bodies, comparable to the glory of the stars.
It is metaphorical look at the comparable glories that people will recieve in the resurrection. But notice that all of these glories are considered heaven. So the vast majority of persons that have ever lived on earth will go to heaven, but it depends on Jesus Christ and them as to which heaven and kind of glorified body they will enjoy for eternity.
Finally, we do not get this information just from the bible. JS recieved this information directly from the Lord Jesus Christ. JS just references the 15th chapter of Corinthians. That is how the apostles received information in the first century church, by revelation from Jesus Christ who was in heaven.
If it is truth you want then you can't believe this. If it's JS' believes you want, then believe them. This is not what the bible says---I've given you what those words mean in the Greek and you still refuse to understand. This is not saying we have different glorified bodies, it is saying we have different bodies from the sun, moon and stars, just as birds, fish and animals all have their different bodies. Nowhere does it say, we will have celestial bodies, it does say we will have spiritual bodies.
1Co 15:44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
1Co 15:45 And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
1Co 15:46 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
1Co 15:47 The first man is of the earth, earthy: the second man is the Lord from heaven.
1Co 15:48 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.
1Co 15:49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
The whole of 1 Cor 15 is about the resurrection, that is right. But why do you take just a few words and disregard the rest? That is what you do with most verses.
Read everything to get to the truth of what is being said!!
1Co 15:50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
1Co 15:51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
1Co 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
1Co 15:53 For this corruptible must put on incorruption, and this mortal must put on immortality.
1Co 15:54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
JS received nothing from Jesus. Jesus knew the meaning of the words terrestrial and celestial---obviously JS didn't.
