The crucifixion was an extreme example of how humans 'nail' other humans to the 'cross' in persecution. The crucifixion was a symbol for the last useless journey people need to take, it represents release from fear to anyone who understands it.
Everyone has acted as if they were being crucified. This is a marked tendency of the 'separated', who always refuse to consider what they have done to themselves. Projection means anger, anger fosters assault and assault promotes fear. The meaning of the crucifixion lies in the apparent intensity of the assault of some of the Sons of God upon another. This of course should be fully understood this is impossible.
Assault can ultimately only be made on the body. There is no doubt that one body can assault or destroy another body. Yet destruction of the mind is impossible, therefore the bodies destruction does not justify the anger. So the message of the crucifixion was intended to teach that it is not necessary to perceive any form of assault in persecution, because you cannot be persecuted. If you respond with anger you must be equating yourself with the destructible and are therefore regarding yourself insanely.
This is why Jesus did not respond to them in their verbal words and bodily damage done to the body. Because they had in effect done nothing to him. And because he did not share in the worlds perception of persecution he did not strengthen it. If you react as if you are persecuted, you teach persecution. This is not a lesson you should want to teach to realize your own 'salvation'. Realize your own perfect immunity which is the truth in you and realize you cannot be assaulted.
