Well, if it was a spiritual resurrection, then the spirit could as well be physically touched and could eat and drink. So, it was not a disembodied ghost-like appearance.
Jesus replied, “Do not touch me, for I have not yet ascended to my Father. Go to my brothers and tell them, ‘I am ascending to my Father and your Father, to my God and your God.'”
Behold my hands and my feet, that it is I myself. Handle me and see, for a spirit does not have flesh and bones as you see I have.’ When he had said this, he showed them his hands and feet.
Then he said to Thomas, “Put your finger here, and examine my hands. Extend your hand and put it into my side. Do not continue in your unbelief, but believe.”
But while they still did not believe for joy, and marveled, he said to them, ‘Have you any food here?’ So they gave him a piece of broiled fish and some honeycomb. And he took it and ate it in their presence.
not by all the people, but by us, the witnesses God had already chosen, who ate and drank with him after he rose from the dead.
