Whosoever is born of God does not commit sin; for his nature remains in him: and he cannot sin, because he is born of God.

And he cannot sin, because he is born of God. Hence Jovinian, Luther, and Calvin taught that a man could not fall away, but was sure of his salvation. But S. John says, "My little children, these things write I unto you, that ye sin not." Consequently they could sin, faithful though they were. And it is contrary to daily experience, for we find daily the faithful becoming heretics and falling into sin. And the Council of Trent (vi23) rules otherwise. What then is S. John"s meaning that he who is born of God cannot sin, that is mortally and gravely? 1. We must take the word collectively—and then it will mean, So long as he preserves the seed of grace, he cannot sin. So Å’cumenius, Thomas Anglicus, Cajetan, and S. Hierom, lib11extra Jovin. And accordingly theologians say that he who has effectual grace cannot sin, because effectual grace in its very conception includes its result. For that grace is called "effectual" which (as is foreseen) will produce its effect, which is to lead our free will to co-operate in a good work. But, speaking abstractedly, he who has effectual grace can resist it, and commit sin. (See Conc. Trid. sess. vi. can4.)
2. He who is born of God cannot (in a formal sense) commit sin, that is as far as relates to his heavenly new birth. For if this be allowed to Acts , and is not withstood by our free will, it is fully able to keep out all sin. (See S. Augustine, de grat. Christi, cap. xxi.) Thus Adam is said in his state of innocence to have been immortal, because he could not die, as long as he remained therein. But as he could fall, so also could he die. Thus we say that this medicine, e.g, is so powerful that any one who takes it could not die of the plague. But a man refuses to take the medicine and then dies; so can he who has the grace of God refuse to use it, and thus fall into sin. S. John here distinguishes between the supernatural action of Divine grace, and the exercise of moral virtues, the first of these preventing every sin, while the others do not. But the habit of temperance is not lost by one act of intemperance, even as temperance is not acquired by a single act of temperance. Again, the grace of Christ is distinguished from the grace given to Adam, which gave the power but not the will, whereas the grace of Christ gives both the will and the power. See S. Augustine (de corrupt. et gratia), "It is so provided (to meet the weakness of the human will), that Divine grace never fails, is never overpowered by any difficulty, so as ever to resolutely will that which is good, and obstinately refuse to abandon it." And it is thus that he explains the words of S. John , "Every one that is born of God sinneth not."
3. He cannot sin. He sins with difficulty. He has no wish to sin, says Å’cumenius. Others explain the words, He has power not to sin, this power being given him by God.
4. Rightfully and properly he cannot sin, though he may in fact sin against all that is right and proper.
5. Gagneius says, "He cannot sin, i.e, by unbelief, which S. John calls a sin unto death."
6. Some take these words as referring to those who are predestinated and absolutely elected to eternal life. But this must be understood, not of antecedent, but consequent impossibility, which consists with our liberty of will, as including and presupposing it.
The first and second of these explanations seem to be the best.
Anagogically. S. Augustine (de peccat. et merit. ii7) says that the righteous man cannot sin, by reason of his hope of eternal life.
In like manner he says (de nupt, et concup. i23 , and de Spirit. et lit. cap. ult.), "We cannot observe perfectly in this life the two commandments, "Thou shalt not covet," and "Thou shalt love the Lord thy God with all thy heart," &c. But we are exhorted to attain to that place where we shall perfectly fulfil them. It is impossible not to feel concupiscence in this world, but we are directed not to yield to it. And the same with the other commandment, "Thou shalt love the Lord thy God." See Rom. vii7."
Morally. S. John here teaches us an easy and certain way of avoiding sin, namely, by carefully attending to those holy inspirations which God suggests, and thus shut out from our minds all the evil suggestions of the devil. For he who sins must needs give way to evil thoughts, for we cannot desire or wish anything unless the mind suggests it to us as a good to be desired. And accordingly the Blessed cannot sin, because they behold God as their chief and boundless good, and are swallowed up in Him as the very abyss of all good. S. Francis Xavier used for this very reason to occupy himself in good thoughts, in ruminating on some holy sentence of Scripture, or the doings or virtues of some saint. For the mind in this way drives out all other thoughts which lead to sin. And so with regard to our will. For he who fixes his mind on holy affections and desires cannot give his mind to evil lusts, and consequently cannot sin. He says with Joseph, "How can I do this wickedness and sin against God?" See Genesis 39:9. As S. Leo says (Serm. viii de Epiphany), "He who wishes to learn whether God dwells within him, should honestly examine the secrets of his heart, and carefully ascertain with what humility he resists pride, with what good will he strive against envy, how he is not charmed with flattering tongues, and how pleased he is at another"s happiness. Whether he does not render evil for evil, and would rather pass over injuries than mar in himself the image of Him who sends His rain upon the just and unjust, and makes His sun to rise on the evil and on the good. And not to enter on a more minute enquiry, let him see whether he find within him such love of God and his neighbour, as to wish to render even to his enemies that which he desires to be rendered to himself."
For His seed remaineth in him. Å’cumenius by the "seed" understands Christ. See Galatians 3:29. (2.) S. Augustine and others understand by it the word of God. See Luke 8:11; James 1:18; 1 Peter 1:23. (3.) Lyra, Hugo, Cajetan, and Thomas Anglicus most fitly understand by it the grace of God. For, 1. All other virtues spring from it2. Because it is the seed of glory. (See D. Thorn. par. i. quæst62 , art3.) 3. Because as a seed must die in order to bear fruit, so does grace suffer death and martyrdom, from whence all good, both public and private, proceeds. See John 12:24.
