Epistle of Polycarp to the Philippians "Wherefore, girding up your loins,"[8] Clement of Alexandria Exhortation to the Heathen "Let us array ourselves in the armour of peace, putting on the breastplate of righteousness, and taking the shield of faith, and binding our brows with the helmet, of salvation; and the sword of the Spirit, which is the word of God,"[166] Tertullian Against Marcion Book III 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."[200]
