"And Jesus punctured his brand new body just for show (see doubting Thomas narrative)?"
Jesus rose from the grave with a heavenly, non Adamic body, with no blood. His Adamic blood was shed in place of yours and mine.
His wounds will testify forever that he took our punishment on Himself.
Did you forget the fact that He ate with his disciples after His Resurrection? Why would He need to do that if there was no blood to deliver the nutrients to His cells. Also, does a Heavenly body defecate? I only ask because, if you believe it does not, Jesus performed another miracle in the sublimation of the food He ate.
