“If, however, you will not acknowledge John, you have our common master Paul, who "girds our loins about with truth, and puts on us the breastplate of righteousness, and shoes us with the preparation of the gospel of peace, not of war; who bids us take the shield of faith, wherewith we may be able to quench all the fiery darts of the devil, and the helmet of salvation, and the sword of the Spirit, which (he says) is the word of God." This sword the Lord Himself came to send on earth, and not peace.”
