After resurrection Jesus first appeared to Mary Magdalene. That was before his first ascencion and his body clould not be touched because was not glorified yet. We dont know for sure what did happens after this first appearance to May. Why or how Jesus walked away from her and she alouded that to happens. The best guess is that Jesus didnt walk away but he went to heaven for a first time.
Then he appeared to two disciples on theyr way to Emaus. Did Jesus walked from the sepuklcre to Emaus? Did he walked back to Jerusalem?
(sorry I have to go)
Luke in his Gospel sugest that the/an ascencion ocurred the day of the resurrection. Same Luke in Acts sugest that the/an ascencion ocurred just before Penthecost. If Luke is not contradicting himself, we have two options. One option is to asume that Jesus did ascend many times, at least two. Other option is to asume that both acounts refer to the same ascencion.
The second option force the Luke ascencion to ocurr not the same day but 40 days jumping into the future. Also forces the details making Jesus to found the Apostles in Jerusalem, take them to Bethany and then to the Mount of the Olives. We have to keep on mind that for the Gospels the "Mount of the Olives" usually (all the times) refer to the side infront of Jerusalem and the Temple; oposite side and far away of bethany.
In my opinion, if there is not iother option...I will support that Jesus did meet the Apostles in Jerusalem, took them to Bethany and finally to the Mount of the Olives. But I think there is not need for that.
The acounts of the resurrection in all the Gospels sugest that Jesus did ascend to heaven more than those two times. If we keep believing that Jesus did ascend a single time, the day before Penthecost, the we enter in serious problems. In other hand I dont see any problem at all in accepting that Jesus did apears multiple times and did ascend each time.
Firts of all: it is not true that ascending to heaven is being entrowned. Many persons in the Bible did ascend to heaven and were not entrowned.
Second: being entrowned dont seems to be an obstacle for Jesus Christ (God) to phisically apears to the disciples.
Third: the number of aparitions and the details of how they ocurred; plus the silence on how Jesus Christ did desapear, is sugesting a ascencion each time.
Forth: it became problematic to explain where did Jesus stayed all those 40 days, hide of the Jew and from the disciples.
Most important: Jesus body could not be touched (it was possible but not alouded) until he went to the Father. His first aparition to Mary ocurred before Jesus went to the Father. The aparition to Thomas ocurred after Jesus went to the Father and yet before the ascencion the day before Penthecost.
Also: from birth to ascencion Jesus did not have any divine supernatural power or hability. The acounts of the aparitions points to a allmighty Christ, not the Jesus of the Gospels.
Now check the aparitipos:
The day of the resurrection: to Mary alone; to the women, to Peter alone, to the disciples on the way to Emaus, to 10 disciples.
Next days: to the 11, to seven, to the fisherman apostles, to 500.
