Act 10:40 (YLT) `This one God did raise up the third day, and gave him to become manifest,
41 not to all the people, but to witnesses, to those having been chosen before by God--to us who did eat with him , and did drink with him, after his rising out of the dead
If Jesus' resurrection body was in flesh, that verse has no sense. I can see that Jesus was resurrected in spirit, and it was allowed by God to appear just to his disciples. That is what this says, and I believe so. Same thing angels did (even Jesus himself) in the old times.
Luke 24 -
"37 But having been terrified, and having been filled with fear,
they were thinking themselves to see a spirit.
38 And He said to them, “Why are you troubled, and why do
doubts come up in your hearts? 39
See My hands and My feet, that I am He. Touch Me and see,
for a spirit does not have flesh and bones, as you see Me having.” 40 And having said this, He showed to them the hands and the feet.
41 And while they still were disbelieving for joy and were wondering, He said to them, “Have you anything here to eat?” 42 And they gave to Him part of a broiled fish.b 43 And having taken it, He ate it before them."
Note, He doesn't say, "as ye see me
appear to have"
[Phil3:21 - "who will transform our
body of humiliation, conformed to the
body of His glory, according to the working enabling Him even to subdue all things to Himself."]
