Ok, but what I was pointing out is that mainstream Christianity also believes that Enoch, Elija, and Jesus as well as Mary in the RCC were bodily assumed/ascended to Heaven. So, either the verse in 1 Corinthians means something else than you are positing, or we also have a difficulty.
Matthew 16:17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for
flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
1 Corinthians 15:50 Now this I say, brethren, that
flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
Galatians 1:16 To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with
flesh and blood:
Ephesians 6:12 For we wrestle not against
flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
Hebrews 2:14 Forasmuch then as the children are partakers of
flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
1 Corinthians 15:40-57 J.B. Phillips New Testament (PHILLIPS)
40-41 There are bodies which exist in this world, and bodies which exist in heaven. These bodies are not, as it were, in competition; the splendour of an earthly body is quite a different thing from the splendour of a heavenly body. The sun, the moon and the stars all have their own particular splendour, while among the stars themselves there are different kinds of splendour.
42-44 These are illustrations here of the raising of the dead. The body is “sown” in corruption; it is raised beyond the reach of corruption. It is “sown” in dishonour; it is raised in splendour. It is sown in weakness; it is raised in power. It is sown a natural body; it is raised a spiritual body. As there is a natural body so will there be a spiritual body.
45 It is written, moreover, that: ‘The first man Adam became a living being’.
46-49 So the last Adam is a life-giving Spirit. But we should notice that the order is “natural” first and then “spiritual”. The first man came out of the earth, a material creature. The second man came from Heaven and was the Lord himself. For the life of this world men are made like the material man; but for the life that is to come they are made like the one from Heaven. So that just as we have been made like the material pattern, so we shall be made like the Heavenly pattern.

For I assure you, my brothers, it is utterly impossible for flesh and blood to possess the kingdom of God. The transitory could never possess the everlasting.
The dead and the living will be fitted for immortality
51-53 Listen, and I will tell you a secret. We shall not all die, but suddenly, in the twinkling of an eye, every one of us will be changed as the trumpet sounds! The trumpet will sound and the dead shall be raised beyond the reach of corruption, and we who are still alive shall suddenly be utterly changed. For this perishable nature of ours must be wrapped in imperishability, these bodies which are mortal must be wrapped in immortality.
54 So when the perishable is lost in the imperishable, the mortal lost in the immortal, this saying will come true: ‘Death is swallowed up in victory’ ‘O death, where is your sting? O Hades, where is your victory?’
55-57 It is sin which gives death its power, and it is the Law which gives sin its strength. All thanks to God, then, who gives us the victory over these things through our Lord Jesus Christ!
1 Corinthians 15:40-55 Good News Translation (GNT)
40 And there are heavenly bodies and earthly bodies; the beauty that belongs to heavenly bodies is different from the beauty that belongs to earthly bodies. 41 The sun has its own beauty, the moon another beauty, and the stars a different beauty; and even among stars there are different kinds of beauty.
42 This is how it will be when the dead are raised to life. When the body is buried, it is mortal; when raised, it will be immortal. 43 When buried, it is ugly and weak; when raised, it will be beautiful and strong. 44 When buried, it is a physical body; when raised, it will be a spiritual body. There is, of course, a physical body, so there has to be a spiritual body. 45 For the scripture says, “The first man, Adam, was created a living being”; but the last Adam is the life-giving Spirit. 46 It is not the spiritual that comes first, but the physical, and then the spiritual. 47 The first Adam, made of earth, came from the earth; the second Adam came from heaven. 48 Those who belong to the earth are like the one who was made of earth; those who are of heaven are like the one who came from heaven. 49 Just as we wear the likeness of the man made of earth, so we will wear[a] the likeness of the Man from heaven.
50 What I mean, friends, is that what is made of flesh and blood cannot share in God's Kingdom, and what is mortal cannot possess immortality.
51-52 Listen to this secret truth: we shall not all die, but when the last trumpet sounds, we shall all be changed in an instant, as quickly as the blinking of an eye. For when the trumpet sounds, the dead will be raised, never to die again, and we shall all be changed. 53 For what is mortal must be changed into what is immortal; what will die must be changed into what cannot die. 54 So when this takes place, and the mortal has been changed into the immortal, then the scripture will come true: “Death is destroyed; victory is complete!”
55 “Where, Death, is your victory?
Where, Death, is your power to hurt?”
Look at each use in scripture and I cor 15 in context. Are you aware of the parallelism in verse 50?
