Haydock's commentary
Sins. Who can always decide when a sin is only venial? (Haydock)
Though I may have avoided the grosser transgressions, how can I be assured that my heart is innocent? (Calmet)
This assurance is reserved for Methodists, who seem to look upon it as essential, before a person can obtain salvation. But where does God specify this condition? We know that (Haydock) we are to work out our salvation in fear and trembling; and that St. Paul, though conscious to himself of nothing, said: yet in this I am not justified, &c., 1 Corinthians iv. 4., and ix. 27., and Philippians ii. 12. Hebrew speaks of "ignorances," which might not however be wholly blameless. (Berthier)
Ones, or enemies: "....and from the proud preserve." (Symmachus; Chaldean) But he alludes to the distinction of sins of ignorance and of pride, (Leviticus iv. 2., and Numbers xv. 30.; Calmet) or malice. (Haydock)
David had not fallen into many sins of the latter description, though his adultery and murder were such. But the former are daily sins, into which even the just fall frequently. (Calmet)
None can be assured of their state, (Ecclesiastes ix.) but are kept between hope and fear. (Worthington)

The Fathers on this verse
St Cyprian Three Books of Testimonies Against the Jews, Testimony LVI
In the Wisdom of Solomon: “In every place the eyes of God look upon the good and evil.” Also in Jeremiah: “I am a God at hand, and not a God afar off. If a man should be hidden in the secret place, shall I not therefore see him? Do not I fill heaven and earth? saith the Lord.” Also in the first of Kings: “Man looketh on the face, but God on the heart.” Also in the Apocalypse: “And all the churches shall know that I am the searcher of the reins and heart; and I will give to every one of you according to his works.” Also in the eighteenth Psalm: “Who understands his faults? Cleanse Thou me from my secret sins, O Lord.” Also in the second Epistle of Paul to the Corinthians: “We must all be manifested before the tribunal of Christ, that every one may bear again the things which belong to his own body, according to what he hath done, whether good or evil.”
St Methodius From the Discourse on the Resurrection, Chapter II
I. Read a compendious interpretation of some apostolic words from the same discourse. Let us see, then, what it is that we have endeavoured to say respecting the apostle. For this saying of his, “I was alive without the law once,” refers to the life which was lived in paradise before the law, not without a body, but with a body, by our first parents, as we have shown above; for we lived without concupiscence, being altogether ignorant of its assaults. For not to have a law according to which we ought to live, nor a power of establishing what manner of life we ought to adopt, so that we might justly be approved or blamed, is considered to exempt a person from accusation. Because one cannot lust after those things from which he is not restrained, and even if he lusted after them, he would not be blamed. …
St Methodius From the Discourse on the Resurrection, Chapter II
III. For the apostle here sets forth clearly, as I think, three laws: One in accordance with the good which is implanted in us, which clearly he calls the law of the mind. One the law which arises from the assault of evil, and which often draws on the soul to lustful fancies, which, he says,” wars against the law of the mind.” And the third, which is in accordance with sin, settled in the flesh from lust, which he calls the “law of sin which dwells in our members;” which the Evil One, urging on, often stirs up against us, driving us to unrighteousness and evil deeds. For there seems to be in ourselves one thing which is better and another which is worse. …
St Augustine Book II, Chapter IX
17. By what feelings, then, was I animated? For it was in truth too shameful; and woe was me who had it. But still what was it? “Who can understand his errors?” We laughed, because our hearts were tickled at the thought of deceiving those who little imagined what we were doing, and would have vehemently disapproved of it. Yet, again, why did I so rejoice in this, that I did it not alone? Is it that no one readily laughs alone? No one does so readily; but yet sometimes, when men are alone by themselves, nobody being by, a fit of laughter overcomes them when anything very droll presents itself to their senses or mind. Yet alone I would not have done it, alone I could not at all have done it. …
St Augustine City of God, That We Ought Not to Expect to Find Any Efficient Cause of the Evil Will
Let no one, therefore, look for an efficient cause of the evil will; for it is not efficient, but deficient, as the will itself is not an effecting of something, but a defect. For defection from that which supremely is, to that which has less of being, this is to begin to have an evil will. Now, to seek to discover the causes of these defections, causes, as I have said, not efficient, but deficient, is as if some one sought to see darkness, or hear silence. Yet both of these are known by us, and the former by means only of the eye, the latter only by the ear; but not by their positive actuality, but by their want of it. Let no one, then seek to know from me what I know that I do not know; unless he perhaps wishes to learn to be ignorant of that of which all we know is, that it cannot be known. …
St Augustine A Treatise Concerning Man’s Perfection in Righteousness, The Fifth Passage
“This,” says he, “is another text of theirs: ‘Who will boast that he has a pure heart?’” And then he answered this with several passages, wishing to show that there can be in man a pure heart. But he omits to inform us how the passage which he reported as quoted against himself must be taken, so as to prevent Holy Scripture seeming to be opposed to itself in this text, and in the passages by which he makes his answer. We for our part indeed tell him, in answer, that the clause, “Who will boast that he has a pure heart?” is a suitable sequel to the preceding sentence, “whenever a righteous king sits upon the throne.” For how great soever ever a man’s righteousness may be, he ought to reflect and think, lest there should be found something blameworthy, which has escaped indeed his own notice, when that righteous King shall sit upon His throne, whose cognizance no sins can possibly escape, …
St Augustine Expositions on the Book of Psalms, Psalm XIX
13. “Who understandeth sins?” ( ver. 12. ) But what sort of sweetness can there be in sins, where there is no understanding? For who can understand sins, which close the very eye, to which truth is pleasant, to which the judgments of God are desirable and sweet? yea, as darkness closes the eye, so do sins the mind, and suffer it not to see either the light, or itself.
St Augustine Expositions on the Book of Psalms, Psalm XXXVI
15. “Let not the foot of pride come against me” ( ver. 11 ). But now he said, The children of men shall put their trust under the shadow of Thy wings: they shall be satiated with the fulness of Thy House. When one hath begun to be plentifully overflowed with that Fountain, let him take heed lest he grow proud. For the same was not wanting to Adam, the first man: but the foot of pride came against him, and the hand of the sinner removed him, that is, the proud hand of the devil. As he who seduced him, said of himself, “I will sit in the sides of the north;” so he persuaded him, by saying, “Taste, and ye shall be as gods.” By pride then have we so fallen as to arrive at this mortality. And because pride had wounded us, humility maketh us whole. God came humbly, that from such great wound of pride He might heal man. …
St Augustine Expositions on the Book of Psalms, Psalm XL
“Innumerable evils have compassed me about” ( ver. 12 ). Who can number sins? Who can count his own sins, and those of others? A burden under which he was groaning, who said, “Cleanse Thou me from my secret faults; and from the faults of others, spare Thou Thy servant, O Lord.” Our own are too little; those “of others” are added to the burden. I fear for myself; I fear for a virtuous brother, I have to bear with a wicked brother; and under such burthen what shall we be, if God’s mercy were to fail? “But Thou, Lord, remove not afar off.” Be Thou near unto us! To whom is the Lord near? “Even” unto them that “are of a broken heart.” He is far from the proud: He is near to the humble. …
St Augustine Expositions on the Book of Psalms, Psalm LXXI
6. “O God, deliver me from the hand of the sinner” ( ver. 4 ). Generally, sinners, among whom is toiling he that is now to be delivered from captivity: he that now crieth, “Unhappy man I, who shall deliver me from the body of this death? The grace of God through Jesus Christ our Lord.” Within is a foe, that law in the members; there are without also enemies: unto what cryest thou? Unto Him, to whom hath been cried, “From my secret sins cleanse me, O Lord, and from strange sins spare Thy servant.”…But these sinners are of two kinds: there are some that have received Law, there are others that have not received: all the heathen have not received Law, all Jews and Christians have received Law. Therefore the general term is sinner; either a transgressor of the Law, if he hath received Law; or only unjust without Law, if he hath not received the Law. …
St Jerome Jerome's Apology for Himself Against the Books of Rufinus, His confession of faith is unsatisfactory. No one asked him about the Trinity, but about Origen's doctrines of the Resurrection, the origin of souls, and the salvability of Satan. As to the Resurrection and to Satan he is ambiguous. As to souls he professes ignorance
You seem to me here to speak a little too hardly of the devil, and to assail the accuser of all with false accusations. You say ‘he is the universal cause of sin;’ and, while you make him the author of all crimes, you free men from fault, and take away the freedom of the will. Our Lord says that ‘from our heart come forth evil thoughts, murders, adulteries, fornications, thefts, false witnesses, railings,’ and of Judas we read in the Gospel; “After the sop Satan entered into him,” that is, because he had before the sop sinned voluntarily, and had not been brought to repentance either by humbling himself or by the forbearance of the Saviour. …
St Jerome The Letters of St. Jerome, To Demetrius
But let us turn back to the passage first quoted, “If the spirit of the ruler rise up against thee, leave not thy place,” a sentence which is followed by these words: “for yielding pacifieth great offences.” The meaning is, that if the serpent finds his way into your thoughts you must “keep your heart with all diligence” and sing with David, “cleanse thou me from secret faults: keep back thy servant also from presumptuous sins,” and come not to “the great transgression” which is sin in act. Rather slay the allurements to vice while they are still only thoughts; and dash the little ones of the daughter of Babylon against the stones where the serpent can leave no trail. …
3 more passages of the Fathers cite this verse. The Motif Searcher in the palace lists them all.
The Fathers are given as they wrote. Where a passage lays the Passion on the Jewish people, the Church teaches that it cannot be charged against all the Jews then living, nor against the Jews of today, and that all sinners were its authors (CCC 597, 598).
