Luke 14:31 – Jesus acknowledges the legitimacy of war in this parable.
This parable has to do with the cost of discipleship, the kings going to war is an example of preparation. To say war is legitimated here is taking it out of narrative context.
Luke 19:27 – Jesus says “But as for these enemies of mine, who did not want me to reign over them, bring them here and slay them before me.” Jesus teaches that not all killing is intrinsically evil.
Completely out of context, this is said by a character in Jesus’ parable not a command of Jesus. This parable “STORY” has nothing to do with Jesus commanding us to kill certain people.
Luke 22:36 – Jesus says “let him who has no sword sell his mantle and buy one.” Jesus encourages the legitimate defense against an aggressor.
Out of context, this is a about a reference to Isa 53:12 and how God will interceded even for the “trangressers”. This verse is right after the betrayel annoucement. Jesus is almost making fun of them for using the sword. This needs to be fulfiiled by Jesus no by the violent Messiah the Jews wanted. Also when he says “it is enough” he’s not saying two is enough swords, he’s saying don’t ever speak to me about weapons again.
Rom. 13:3-4 – Paul commends us to those in authority, and exalts a man who “does not bear the sword in vain.” Paul calls such a man “the servant of God to execute his wrath on the wrongdoer.”
Look up 1 Thess 4:6, again Context, read the whole Chapter. Read about the cultural context in play here and about submission to authority, and what “authority” Paul is talking about.
Obviously there is plenty of scripture emphasizing God’s desire to avoid war and conquer evil with good. There is nothing in Scripture says that legitimately defending oneself or one’s country which results in the killing of another is an intrinsically evil act.
