Prov 18:3

“As to [the Arians'] blasphemous position that "the Son knows not the Father perfectly," we ought not to wonder at it; for having once set themselves to fight against Christ, they contradict even his express words, since he says, "As the Father knows me, even so I know the Father." Now if the Father knows the Son but in part, then it is evident that the Son does not know the Father perfectly. It is not lawful to say this. The Father does know the Son perfectly; then it is evident that as the Father knows his own Word, so also the Word knows his own Father whose Word he is.By these arguments and references to the sacred Scriptures we frequently overthrew them; but they changed like chameleons and again shifted their ground, striving to bring upon themselves that sentence, "When an ungodly man comes into a depth of evils, he despises them."”

“Just as men who plunge into the deep, the deeper they go down, they descend into darker and deeper places, so it is with humankind. For they did not keep to idolatry in a simple form, nor did they abide in that with which they began. But the longer they went on in their first condition, the more new superstitions they invented, and, not satiated with the first evils, they again filled themselves with others, advancing further in utter shamefulness and surpassing themselves in impiety. But to this divine Scripture testifies when it says, "When an ungodly man comes into a depth of evils, he despises them."”

“"When the godless fall to the depths of evil, they lose all sense of respect." It is a terrible thing, you see, dearly beloved, a terrible thing to fall into the clutches of the devil. I mean, the soul then, as though caught in a net, and like a boar trapped in the mire, is likewise caught up in pleasure and, swept along by its evil habits, it loses all sense of the foul odor of its sins. Consequently, we must be awake and on our guard so as never to allow the evil demon any entrance at the outset, lest he cloud our reasoning, blind the sharp vision of our mind, and thus as if robbing us of sunlight render us unable to see the rays of the sun of justice and cause us to fall into the abyss.”

“Confession dies with a dead man, but is always possible for one who is alive. There is this saying, "When a sinner shall have come into the depth of evil things, he despises [them]." For it is one thing to long for, another thing to fight against righteousness. It is one thing to desire to be delivered from evil, another thing to defend one's evil doings rather than to confess.”

“The proud and recalcitrant who despair of the forgiveness of sins repudiate forgiveness. Not only do they with pitiable blindness reject the care for their own salvation, but they also do not rest from upsetting other faithful souls with deadly words, if they are unable to pervert them. Often, either the frightfulness of their sins or the length of a wicked life takes away from them the hope of salvation and drives them to perpetrate even worse things in such a way that in such people that statement of holy Scripture is fulfilled: "When wickedness comes, contempt comes also."”

“Not only slight sins but even greater offenses try to overtake us day and night. So let us not hold back repentance until the end of life, but while we are living let us endeavor to do penance daily. This practice should be observed continuously, not only by the laity and clerics, but even by priests and monks.… Since we cannot spend a day without sin, what is the sense of gradually piling up slight offenses and thus making endless streams of tiny drops? Despair arises from a multitude of sins heaped up over time, according to the words: "The wicked man, when he has come into the depth of sins, despises [them]." Of course, you are all well aware that we can more easily uproot them when they are still young than cut them off when they are firm.”

“Believe this devoutly and firmly: God never abandons a person unless he himself has already deserted God. Although a person may have committed serious sins once, twice and a third time, God still looks for him, as he says through the prophet, "that by his conversion he may live." However, when he begins to continue in his sins, despair arises from the multitude of them, and hardening is caused by the despair. While careless people at first despise their own sins because they are small, if these slight offenses increase, crimes are even added; they heap up to finally overwhelm them, and when this happens there is fulfilled what is written: "With wickedness comes contempt."”

“The evil mind is always set in pains and labours, since it is either contriving mischiefs that it may bring down, or fearing lest these be brought down upon it by others; and whatever plot it hatches against neighbours, it is afraid of being hatched by neighbours against itself. It is on every side full of suspicions, on every side full of alarms. Everyone that occurs to mind is supposed to be making out things hostile to him, and so he, to whom the repose of security is wanting, has surely 'a dreadful sound in his ears' always. And it often happens that his neighbour, whoever he be, speaks to him with a single intention, and designs nothing hostile, but 'when there is peace, he suspecteth plots;' in that he, who is always dealing craftily, calculates that there is not single dealing towards himself. And whereas it is written, When the wicked man cometh into the pit of sinners, he contemneth, he being encompassed with the darkness of his iniquity henceforth despairs of light.”

“The impious man, when he has come into the depth of sins, despises, etc. He who, being wrapped in the long darkness of sins, despairs of the light, already out of desperation, loosens the reins for himself to sin everywhere. But such a one by no means escapes the reproach of future damnation, whom the memory of divine fear did not restrain from the practice of his iniquity.”
