(Hom. xxviii. 2) Then because it seemed incredible that man should prefer light to darkness, he gives the reason of the infatuation, viz. that their deeds were evil. And indeed had He come to Judgment, there had been some reason for not receiving Him; for he who is conscious of his crimes, naturally avoids the judge. But criminals are glad to meet one who brings them pardon. And therefore it might have been expected that men conscious of their sins would have gone to meet Christ, as many indeed did; for the publicans and sinners came and sat down with Jesus. But the greater part being too cowardly to undergo the toils of virtue for righteousness' sake, persisted in their wickedness to the last; of whom our Lord says, Every one that doeth evil, hateth the light. He speaks of those who choose to remain in their wickedness.
(Hom. xxvii. 2) No one reproves a Pagan, because his own practice agrees with the character of his gods; his life is in accordance with his doctrines. But a Christian who lives in wickedness all must condemn. If there are any Gentiles whose life is good, I know them not. But are there not Gentiles? it may be asked. For do not tell me of the naturally amiable and honest; this is not virtue. But show me one who has strong passions, and lives with wisdom. You cannot. For if the announcement of a kingdom, and the threats of hell, and other inducements, hardly keep men virtuous when they are so, such calls will hardly rouse them to the attainment of virtue in the first instance. Pagans, if they do produce any thing which looks well, do it for vain-glory's sake, and will therefore at the same time, if they can escape notice, gratify their evil desires as well. And what profit is a man's sobriety and decency of conduct, if he is the slave of vain-glory? The slave of vain-glory is no less a sinner than a fornicator; nay, sins oven oftener, and more grievously. However, even supposing there are some few Gentiles of good lives, the exceptions so rare do not affect my argument.
Yet he came not to judge or to enquire, but to pardon and remit transgressions, and to grant salvation through faith. How then fled they? Had He come and sat in His Judgment seat, what He said might have seemed reasonable; for he that is conscious to himself of evil deeds, is wont to fly his judge. But, on the contrary, they who have transgressed even run to one who is pardoning. If therefore He came to pardon, those would naturally most hasten to Him who were conscious to themselves of many transgressions; and indeed this was the case with many, for even publicans and sinners sat at meat with Jesus. What then is this which He saith? He saith this of those who choose always to remain in wickedness. He indeed came, that He might forgive men's former sins, and secure them against those to come; but since there are some so relaxed, so powerless for the toils of virtue, that they desire to abide by wickedness till their latest breath, and never cease from it, He speaks in this place reflecting upon these. "For since," He saith, "the profession of Christianity requires besides right doctrine a sound conversation also, they fear to come over to us, because they like not to show forth a righteous life. Him that lives in heathenism none would blame, because with gods such as he has, and with rites as foul and ridiculous as his gods, he shows forth actions that suit his doctrines; but those who belong to the True God, if they live a careless life, have all men to call them to account, and to accuse them. So greatly do even its enemies admire the truth." Observe, then, how exactly He layeth down what He saith. His expression is, not "He that hath done evil cometh not to the light," but "he that doeth it always, he that desireth always to roll himself in the mire of sin, he will not subject himself to My laws, but chooses to stay without, and to commit fornication without fear, and to do all other forbidden things. For if he comes to Me, he becomes manifest as a thief in the light, and therefore he avoids My dominion." For instance, even now one may hear many heathen say, "that they cannot come to our faith, because they cannot leave off drunkenness and fornication, and the like disorders."
But if God hath discovered all men's works to be evil, how is it that any have done the truth, and come to the light, i. e. to Christ? Now what He saith is, that they loved darkness rather than light; He lays the stress upon that. Many have loved their sins, many have confessed them. God accuseth thy sins; if thou accuse them too, thou art joined to God. Thou must hate thine own work, and love the work of God in thee. The beginning of good works, is the confession of evil works, and then thou doest the truth: not soothing, not flattering thyself. And thou art come to the light, because this very sin in thee, which displeaseth thee, would not displease thee, did not God shine upon thee, and His truth show it unto thee. And let those even who have sinned only by word or thought, or who have only exceeded in things allowable, do the truth, by making confession, and come to the light by performing good works. For little sins, if suffered to accumulate, become mortal. Little drops swell the river: little grains of sand become an heap, which presses and weighs down. The sea coming in by little and little, unless it be pumped out, sinks the vessel. And what is to pump out, but by good works, mourning, fasting, giving and forgiving, to provide against our sins overwhelming us?
People love truth when it shines on them and hate it when it rebukes them. For, because they are not willing to be deceived but definitely want to practice the art of deception, they love truth when it reveals itself and hate it when it reveals them. Because of this, truth shall requite them in such a way that those who were unwilling to be discovered by it are not only discovered by it against their will but also without revealing itself to them. This is the way the human mind, so blind and sick, so base and unseemly, desires to lie concealed but still not wanting anything to be concealed from it. Instead, it receives quite the opposite—not only is it not concealed from the truth, but the truth is concealed from it. Yet, even while it is as wretched as that, it still ultimately prefers to rejoice in truth rather than in falsehood. It looks forward to the day when, without any further trouble intervening, it will rejoice in that one truth by whom everything else is true.
Because they dislike being deceived, and like to deceive, they love light for discovering herself, and hate her for discovering them. Wherefore it shall be their punishment, that she shall manifest them against their will, and herself not be manifest unto them. They love the brightness of truth, they hate her discrimination; and therefore it follows, Neither cometh to the light, that his deeds should be reproved.
Profitably doth He go over what has been said, and convicts indolence unto things helpful of proceeding from love of evil, and of having its root in unwillingness to learn those things whereby one may become wise and good. For the doer of evil, says He, flees from and refuses the being in the Divine Light: not hiding from shame on account of evil (for so he would have been saved) but desiring to remain in ignorance of what is becoming, lest transgressing he should be smitten, falling upon the now keener convictions of his own conscience, and by means of at length clearly knowing what is good, should pay a more woeful account to the Judge, if he should not do what was pleasing to God.
(in loc. c. 1) He calls Himself the light, whereof the Evangelist speaks, That was the true light; whereas sin He calls darkness.
Morally too they love darkness rather than light, who when their preachers tell them their duty, assail them with calumny.
But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
