My question is inspired by the top answer to this question, according to which transubstantiation (that the bread and the wine literally became the flesh and blood of Jesus) also occurred on the last supper.
I take this means that they ate of Jesus body before his crucifixion(?)
Later, after this death, he appeared to the disciples while Thomas was present, as explained in John 20:24-27:
24 Now Thomas (also known as Didymus[a]), one of the Twelve, was not with the disciples when Jesus came. 25 So the other disciples told him, “We have seen the Lord!” But he said to them, “Unless I see the nail marks in his hands and put my finger where the nails were, and put my hand into his side, I will not believe.” 26 A week later his disciples were in the house again, and Thomas was with them. Though the doors were locked, Jesus came and stood among them and said, “Peace be with you!” 27 Then he said to Thomas, “Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe.”
This passage only mentions the marks from the nails and the spear wound on his side.
Question:
Would the consuming of his flesh not have left some kind of marks that he could then have been identified on?
