Psalms 119:120

Beloved, our condition needs much endurance; and endurance is produced when doctrines are deeply rooted. For as no wind is able by its assaults to tear up the oak, which sends down its root into the lower recesses of the earth, and is firmly clenched there; so too the soul which is nailed by the fear of God none will be able to overturn. Since to be nailed is more than to be rooted. Thus the Prophet prayeth, saying, "Nail my flesh by Thy fear"; "do Thou so fix and join me, as by a nail riveted into me."

O the divine mystery of that cross, on which weakness hangs, might is free, vices are nailed and triumphal trophies raised. So that a certain saint said, "Pierce my flesh with nails for fear of you"; he says not with nails of iron but of fear and faith. For the bonds of virtue are stronger than those of punishment. Lastly, Peter was bound by his faith, when he had followed the Lord as far as the hall of the high priest; no one had bound and punishment had not loosened Peter, who had been bound by faith. Again, when Peter was bound by the Jews, prayer loosed him, punishment did not hold him, because he had not gone back from Christ.

The grace of God, then, being known, which alone freeth from transgression, which is committed through knowledge of the law, he saith, in prayer, "Fix with nails my flesh in Thy fear" (ver. 120). For this some Latin interpreters have literally rendered the Greek καθήλωσον, which that language has expressed in one word. Some have preferred to render by the word confige, without adding clavis; and while they thus desire to construe one Latin by one Greek word, have failed to express the full meaning of the Greek καθήλωσον, because in confige nails are not mentioned, but καθήλωσον cannot be taken but of nails, nor can "fix with nails" be expressed without using two words in Latin. ...Hath he added, "For I have feared Thy judgments"? What meaneth, "Fix me in Thy fear: for I have feared"? If he had already feared, or if he was now fearing, why did he still pray God to crucify his flesh in His fear? Did he wish so much additional fear imparted to him as would suffice for crucifying his flesh, that is, his carnal lusts and affections; as though he should say, Perfect in me the fear of Thee; for I have feared Thy judgments? But there is here even a higher sense, which must, as far as God alloweth, be derived from searching the recesses of this Scripture: that is, in the chaste fear of Thee, which abideth from age to age, let my carnal desires be quenched; "For I have feared Thy judgments," when the law, which could not give me righteousness, threatened me punishment. ...For the inclination to sin liveth, and it then appeareth in deed, when impunity may be hoped for. But when punishment is considered sure to follow, it liveth latently: nevertheless it liveth. For it would rather it were lawful to sin, and it grieveth that what the law forbiddeth, is not lawful; because it is not spiritually delighted with the blessing of the law, but carnally feareth the evil which it threateneth. But that love, which casteth out this fear, feareth with a chaste fear to sin, although no punishment follow; because it doth not even judge that impunity will follow, since from love of righteousness it considereth the very sin itself a punishment. With such a fear the flesh is crucified; since carnal delights, which are forbidden rather than avoided by the letter of the law, are overcome by the delight in spiritual blessings, and also when the victory is perfected are destroyed.
