Caesarius of Arles

This seems to indicate that the people of God did not fight with the hand or weapons so much as with the voice and tongue, that is, they poured forth prayer to God, and thus overcame their adversaries. Therefore, you, too, if you want to be victorious, listen to the apostle say, “Be assiduous in prayer, being wakeful.” This is the most glorious fight of the Christian, not to presume upon his own strength but always to implore the assistance of God.
