Likewise the soldiers asked him, saying, “And what shall we do?” So he said to them, “Do not intimidate anyone or accuse falsely, and be content with your wages.”
Luke 3:14
These are the words of John the Baptist, a man with Old Testament morals. This announced the coming of Christ, but he did not and could not have known about the New Testament, in which there is neither word nor action from Christ that justifies or encourages armed violence.
[Editor's comment: Nevertheless the commands "do not intimidate," "do not accuse falsely," and "be content with your wages" (i.e., do not confiscate or scavenge under color of authority) are limitations on a soldier's aggressiveness.]
