I don’t see any connection whatsoever between my question and your “answer”. “Ba” and “Ka” refer to noncorporeal entities (”soul”). In Jesus’ case the body was definitely physical, not ethereal. So I ask again, how would the Romans have caught, held, and re-cruficied a body that could simply disappear out of their hands and appear elsewhere???
Better question: How could a body which could simply disappear out of their hands and appear elsewhere be corporeal? The basic answer is that it wasn't, even though the experience was sufficiently real.
