You didn’t read the article...
You are basing an entire doctrine upon the omission of the word “blood” from an idiomatic phrase “flesh and blood” which does not mean the same thing, in Biblical context, as “flesh and bones”.
John wrote that we don’t know now what we shall become, but when we see Him, we shall know (what types of bodies we will have in the resurrection). This means John believed Christ was in the same fleshly body He had on the Cross.
The same human flesh body that went up to Heaven.
Jesus only changed into His glorified body AFTER the ascension. And so John writes that “we have not seen Him” in that glorified state, but we will know when we do see Him, what we shall be changed into.
There was nothing spiritual or immortal or immaterial about Jesus’s appearance after He was resurrected, though this did not preclude Him from performing the same miracles He did before the Cross.
Elijah went up to Heaven in a normal body, just as Jesus ascended to Heaven in a normal body of flesh.
Lazarus was raised into his regular body and ate food with Jesus just as Jesus was raised in His regular body and ate food.
And furthermore, your false accusation that I am 'basing an entire doctrine upon the omission of the word blood ' is another of your deceitful little target accusations. I scanned the article and am opposed tot he non-Christian basis for it. You are so deep into error that you must make up attributions so you can attack them!
You asserted, "This means John believed Christ was in the same fleshly body He had on the Cross." No, stupid one, arrogant blustering one, it does not have to mean what you assert! And in fact there is a better meaning that can be drawn IF YOU KNEW YOUR BIBLE BETTER. You foolishly twist the meaning to support what you are trying to prove using the sentence. That circular reasoning is hallmark of the deceived. You are deceived.
Here is another of your assumption strawmen: "And so John writes that we have not seen Him in that glorified state, but we will know when we do see Him, what we shall be changed into." You stupidly switched the cart to before the horse. To see HIM as HE really IS, we must first be changed to be like HIM. But you couldn't stop yourself from piling on false upon false ...
Your assertion, supported by zero evidence offered: "There was nothing spiritual or immortal or immaterial about Jesuss appearance after He was resurrected." Since you are so sure of your false assertion, appear in a locked and shuttered room for me AFTER the doors and shutters have been fastened before your appearance.
Truly these words were offered for people like you:
1 Corinthians 2:14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
I could actually give you Physics reasons why you are in error, but I suspect you are completely closed to learning from Physics OR The Spirit of God in the BIBLE TEXTS.
That body was dead...Lifeless...It had no blood...The blood was on the ground...That's why we drink the new wine at communion...To remember that blood that was drained from Jesus' body...
When the people saw Jesus in the cemetery he told them not to touch him...Something was going on with his new, ready to be resurrected body...
Jesus' appearance was different as we know from scripture...
Just as when we are ready to rise at the rapture...There won't be a bunch of out of the grave bodies hanging around waiting for the blast off so we can be changed en route...When Jesus calls our name, we're outta here...
