It is easy to see how this is misunderstood, most have. But it doesn't say what you assume it says.
The "like manner" does not make void the rest of scripture and the fact that "flesh and blood cannot inherit the kingdom of God." But rather, it tells us that the "like manner" is not like Jesus' first coming in the flesh, but rather that His second coming is in the "like manner" of Him committing only His spirit to the Father. On the contrary, He gave up His "physical" body as a sacrifice.
There is no "physical" return of Jesus, except within the "body" of His church, i.e. "to live is Christ."
That theology is very Ignatius L., yet scripture says this:
Php_3:21 Who shall change our vile body, that it may be fashioned like unto
his glorious body, according to the working whereby he is able even to subdue all things unto himself.
1Co 15:35 But some man will say, How are the dead raised up? and with
what body do they come?
1Co 15:36 Thou fool, that which thou sowest is not quickened, except it die:
1Co 15:37 And that which thou sowest, thou sowest not that body that shall be, but bare grain, it may chance of wheat, or of some other grain:
1Co 15:38 But
God giveth it a body as it hath pleased him, and to every seed his own
body.
1Co 15:39 All
flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds.
1Co 15:40
There are also celestial bodies, and bodies terrestrial: but
the glory of the celestial is one, and the glory of the terrestrial is another.
1Co 15:41 There is one glory of the sun, and another glory of the moon, and another glory of the stars: for one star differeth from another star in glory.
1Co 15:42
So also is the resurrection of the dead. It is sown in corruption;
it is raised in incorruption:
1Co 15:43 It is sown in dishonour;
it is raised in glory: it is sown in weakness; it is raised in power:
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.
Notice, it does not say 'spirit-body' (which is a contradiction in scriptural terms). Jesus was resurrected
bodily, and that body was glorified, 'immortalized', and He is coming back in the same:
Luk_24:39 Behold
my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not
flesh and bones, as ye see me have.
Jud_1:9 Yet Michael the archangel, when contending with the devil he disputed about
the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee.
Rom_5:14 Nevertheless death reigned from Adam
to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come.
Luk 9:30 And, behold, there talked with him two men, which were
Moses and Elias:
Luk 9:31
Who appeared in glory, and spake of his decease which he should accomplish at Jerusalem.
You have a present misunderstanding of 1 Corinthians 15:50, and in doing so, alters your entire belief.
1Co_15:50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
The previous context states:
1Co 15:49 And as we have borne the image of the earthy,
we shall also bear the image of the heavenly.
Thus read 1 Corinthians 15:35-44 just prior, in its speaking of the celestial bodies, the flesh and the glory thereof. The verse of 1 Corinthians 15:50 is parallel to itself, and defines itself, for when Paul states "flesh and blood" it is paralleled by "corruption" in the same sentence. Paul is saying the fallen flesh cannot inherit. He is not saying immortalized glorified flesh (as Jesus, Moses, Elijah, Enoch, the Firstfruits have) cannot. Notice:
1Co 15:53 For this corruptible
must put on incorruption, and this mortal
must put on immortality.
He is speaking of the flesh itself in the power of the resurrection. Just as Jesus is resurrected so too those who died in Him, and those who live will be transformed in a moment, and translated, and be as the angels, who have celestial bodies of flesh (immortal).
