Their recognition of The Risen Jesus was not by His pre-death body. Clearly He looked unremarkably human in form, but his body was not a flesh-and-blood body. It was a spiritual body which they had not seen before. But they recognized him by the bloodless bluish permanently open nail-prints in His hands and feet. Those stigmata were further substantiated by His 40-day perambulations and teaching (of which we have very little record). I believe his body was flesh and bone. His blood was left in heaven when he came back from his high-priestly duties to strengthen the brethren until he ascended again.
How many disciples entered their chamber through the wall?
Did He need to have the stone rolled away to get out of the tomb?
When was the last time you walked through a door without opening it in your flesh-and-blood body?
Why is my comment a nonsequitur to you?
This will be my last post on this topic. Jesus was fully human and fully God at the same time. He had two natures (Hypostatic union). His divine nature was spirit it was both infinite and eternal. It did not require anything to "be"
He also possessed a fully human nature. His human nature allowed Him to walk among us as a man. To exist this nature required the intake of food and drink. It also required air for him to breathe and for him to expel waste products. All of this was required for him to be fully human.
The important thing to remember is that He never stopped being fully human. It would have meant nothing for His divine nature to be resurrected with out His human nature/body to be as well. That would not have been conquering death.
