I think you might be misinterpreting, or outright bastardizing, what the Lord and Savior, Jesus Christ meant when he referenced the sword.
While he had ample opportunity and unlimited power to "cut down his enemies" he lifted nary a hand to DEFEND. Neither himself, nor his "flock".
We defend with prayer and love and a servant's heart. not with man made weapons.
Sorry, but I must respectfully disagree with, and challenge you, on this topic.
