Psalms 11:2

Though the enemy is unseen, we have our faith as a strong protection, according to the saying of the apostle: "In all things taking up the shield of faith, with which you may be able to quench all the fiery darts of the most wicked one." Oftentimes a fiery dart of desire of base indulgence is discharged by the devil; but faith, representing to us the Judgment and cooling the mind, extinguishes the dart.

"For, lo, sinners have bent the bow, they have prepared their arrows in the quiver, that they may in the obscure moon shoot at the upright in heart" [Psalm 11:2]. These be the terrors of those who threaten us as touching sinners, that we may pass over to them as the righteous. "Lo," they say, "the sinners have bent the bow:" the Scriptures, I suppose, by carnal interpretation of which they emit envenomed sentences from them. "They have prepared their arrows in the quiver:" the same words, that is, which they will shoot out on the authority of Scripture, they have prepared in the secret place of the heart. "That they may in the obscure moon shoot at the upright in heart:" that when they see, from the Church's light being obscured by the multitude of the unlearned and the carnal, that they cannot be convicted, they may corrupt good manners by evil communications. [1 Corinthians 15:33] But against all these terrors we must say, "In the Lord I trust."

For behold, the sinners have bent the bow, they have prepared their arrows in the quiver, that they may shoot in the dark the upright of heart. For which it is written in the Hebrew, "For behold, the impious have bent the bow, they have set the arrow upon the string, that they may strike in the dark the upright of heart." Therefore, he says, you wish me to migrate to the mountains, because the sinners, or the impious, burning, have prepared arrows, which must be repelled with the shield of faith. And in their quivers they have darts to strike the just, not in the day, not in the faintly-lit night, when the darkness is tempered by the solace of the moon, but when the night is full, and the darkness is palpable — that is, ψηλαφητὸν σκότος (touchable darkness, psēlaphēton skotos). Know that for this very reason I do not heed your counsels: because the adversaries are prepared for battle, and desire to wound not so much me, whom they cannot overcome, as my just ones; and since I have come from heaven for their salvation, I ought not to leave them orphans. For behold, as you say, they have set their arrow upon the string, and they wish to capture my boys, the sons of my ripening youth, my little young men, with the sweet enticements of pleasures. For all the strength of the devil is in the loin: for which cause also, when Jacob wrestled with me in the struggle, I made his γλαφυρόν (sinew, glaphyron) wither — that is, dry up. Since, therefore, they wish to strike the upright of heart in the darkness, let my just man speak and say: "Your word is a lamp to my feet, O Lord, and a light to my paths." But I, standing in the battle-line and placed in array, do not forsake the contest once begun, especially when you say that they have bent the bow, prepared arrows in the quiver, wish to wound my saints in the darkness, and yet have not yet been able to strike. For they have bent the bow, they have prepared arrows in the quiver, that they may shoot in the dark the upright of heart. Since, then, they are thus prepared, I will set myself in the midst, I will receive their arrows, that my servants may not grieve at my grief, may be healed by my wounds, may not suffer while I suffer, and may say: "O Lord, you have crowned us as with a shield of your good will." But it can also be understood otherwise: that the heretical or adverse powers, through the dogmas of the heretics,…
