Term used as a substitute for peace. In the New Testament of The Bible, Jesus says that He is here not to bring peace to the world, but a sword. The same should be for SPFC's and Christians.
Man: "I'll see you later. Peace!"
SPFC/Christian: "Sword."
Man: "What did you say?"
SPFC/Christian: "I said sword. It is a term used as a substitute for peace. Therefore, I return your greeting to you in this form"
