The weapons of our warfare are not carnal, but powerful before God
Pope Clement VIII, Jerome's Prefaces, On Worship
II. JEROME TO PAULINUS.— Jerome quotes Paul as example of one who learned the law at Gamaliel's feet and then wielded spiritual weapons
"The weapons of our warfare are not carnal, but powerful before God for the destruction of strongholds, destroying counsels and every height that raises itself against the knowledge of God, and bringing every thought captive to the obedience of Christ, and ready to subdue every disobedience."
