ok. Lets go down your road for a bit...if that was the case read further...in the Garden of Gethsamane (SP?) Peter struck the Roman soldier with a sword, thustly cutting off his ear.
It stands to reason to do that, without mortally injuring the soldier, Peter was very adept at using the sword.
If Jesus wanted him to turn the other cheek, why would he have allowed him to carry a sword in the first place? And, IIRC Peter was not the only ARMED one of the disciples.
The early Jews had the death penalty, and it still applied in the time of Jesus, according to the historical writing of Joesephus.
Turning the other cheek was when an other did something wrong that might have not been necessarily a public crime, but maybe a moral crime.
Jesus aslo stated that he could have had LEGIONS of angels at his side to fight with him, but it was NOT THAT TIME.
Why would he fight? If he had JUST CAUSE.
