The Apostle Paul says that you have believed in vain/futility.
1Co 15:14 And if Christ be not risen, then is our preaching vain, and your faith is also vain.
1Co 15:17 And if Christ be not raised, your faith is vain; ye are yet in your sins.
Peter concerning Christ's earthly resurrected body:
Act_13:34 And as concerning that he raised him up from the dead, now no more to return to corruption
According to your doctrine, Christ's earthly resurrected body was exchanged for a body which He had before His incarnation, therefore the earthly body had to suffer some form of corruption by disintegration, erasure, vanishing, hokus pokus, etc.
Therefore, you do not believe in the core doctrine of Christianity concerning Christ's resurrection, never to die again.
According to Paul, salvation depends on believing it.
