I have to admit that I stand corrected by myself when earlier I said that in John, JC said �Don�t touch me!�. I see that later in John, he says to Thomas �Touch me!�. So there is no conflict here after all between the three accounts that mention whether there was physical contact. But this just confirms that JC had a physical body before the ascension.
Having flipped through the four versions of the Gospel (!) I note that most of the differences are pedantic, about minor detail or irrelevant when you interpret to a common meaning. But there are, nonetheless, differences which mean that if one version is correct, the other cannot be. One episode, for example, is the appearance of JC to the disciples after the resurrection.
See Matt 28.16-20: Then the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. 17When they saw him.............
Mark 16.14 Later Jesus appeared to the Eleven as they were eating�..
Luke 24. 33-36: 33They got up and returned at once to Jerusalem. There they found the Eleven and those with them, assembled together...........36While they were still talking about this, Jesus himself stood among them���.(and later ascended)
John 20.19: 19On the evening of that first day of the week, when the disciples were together, with the doors locked for fear of the Jews, Jesus came and stood among them��
John 20.26: 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��.
It is not possible to say that the bible is literal truth because there are four versions of the same story and if just one tiny detail in one version contradicts the same tiny detail in another version, then the bible is not ALL true. This does not mean, of course, that the Gospel is not true. The Gospel remains intact but you simply cannot say that every word in the bible is true.
