Rom. III. 9-18
“What then have we more than they? For we have proved both Jews and Gentiles, that they are all under sin. As it is written, There is none righteous, no, not one: there is none that understands, there is none that seeks after God. They are all gone out of the way, they are together become unprofitable; there is none that does good, no not one. Their throat is an open sepulchre; with their tongues have they used deceit; the poison of asps is under their lips; whose mouth is full of cursing and bitterness: their feet are swift to shed blood: destruction and misery are in their ways: and the way of peace have they not known: there is no fear of God before their eyes.”
He had accused the Gentiles, he had accused the Jews; it came next in order to mention the righteousness which is by faith. For if the law of nature availed not, and the written Law was of no advantage, but both weighed down those that used them not aright, and made it plain that they were worthy of greater punishment, then after this the salvation which is by grace was necessary. Speak then of it, O Paul, and display it. But as yet he does not venture, as having an eye to the violence of the Jews, and so turns afresh to his accusation of them; and first he brings in as accuser, David speaking of the same things at length, which Isaiah mentioned all in short compass, so furnishing a strong curb for them, so that they might not bound off, nor any of his hearers, while the matters of faith were laid open to them, might after this start away; being beforehand safely held down by the accusations of the prophets. For there are three excesses which the prophet lays down; he says that all of them together did evil, and that they did not do good indifferently with evil, but that they followed after wickedness alone, and followed it also with all earnestness. And next that they should not say, “What then, if these things were said to others?” he goes on:
Ver. 19. “Now we know that what things soever the Law says, it says to them who are under the Law.”
This then is why, next to Isaiah, who confessedly aimed at them, he brought in David; that he might show that these things also belonged to the same subject. For what need was there, he means, that a prophet who was sent for your correction should accuse other people. For neither was the Law given to any else than you. And for what reason did he not say, we know that what things soever the prophet says, but what things soever the Law says? It is because Paul uses to call the whole Old Testament the Law. And in another place he says, “Do ye not hear the Law, that Abraham had two sons?” And here he calls the Psalm the Law when he says, “We know that what things soever the Law says, it says to them who are under the Law.” Next he shows that neither are these things he said merely for accusation's sake, but that he may again be paving the way for faith. So close is the relationship of the Old Testament with the New, since even the accusations and reproofs were entirely with a view to this, that the door of faith might open brightly upon them that hear it. For since it was the principal bane of the Jews that they were so conceited with themselves (which thing he mentioned as he went on, “how that being ignorant of the righteousness of God, and going about to establish their own righteousness, they submitted not themselves to the righteousness of God”), the Law and the Prophet by being beforehand with them cast down their high thoughts, and laid low their conceit, that being brought to a consideration of their own sins, and having emptied out the whole of their unreasonableness, and seen themselves in danger of the last extremity, they might with much earnestness run unto Him Who offered them the remission of their sins, and accept grace through faith. And this it is then which St. Paul hints even here, when he says,
“Now we know that what things soever the Law says, it says to them who are under the Law, that every mouth may be stopped, and all the world may become guilty before God.”
Here then he exhibits them as destitute of the boldness of speech which comes of works, and only using a parade of words and behaving in a barefaced way. And this is why he uses so literal an expression, saying, “that every mouth may be stopped,” so pointing out the barefaced and almost uncontrollable pomposity of their language, and that their tongue was now curbed in the strictest sense. For as an unsupportable torrent, so had it been borne along. But the prophet stopped it. And when Paul says, “that every mouth may be stopped,” what he means is, not that the reason of their sinning was that their mouth might be stopped, but that the reason of their being reproved was that they might not commit this very sin in ignorance. “And all the world may become guilty before God.” He does not say the Jew, but the whole of mankind. For the phrase, “that every mouth may be stopped,” is the language of a person hinting at them, although he has not stated it clearly, so as to prevent the language being too harsh. But the words “that all the world may become guilty before God,” are spoken at once both of Jews and of Greeks. Now this is no slight thing with a view to take down their unreasonableness. Since even here they have no advantage over the Gentiles, but are alike given up as far as salvation is concerned. For he would be in strict propriety called a guilty person, who cannot help himself to any excuse, but needs the assistance of another: and such was the plight of all of us, in that we had lost the things pertaining to salvation.
Ver. 20. “For by the Law is the knowledge of sin.”
He springs upon the Law again, with forbearance however (for what he says is not an accusation of it, but of the listlessness of the Jews). Yet nevertheless he has been earnest here with a view (as he was going to introduce his discourse about faith) to show its utter feebleness. For if you boast in the Law, he means, it puts you to the greater shame: it solemnly parades forth your sins before you. Only he does not word it in this harsh way, but again in a subdued tone; “For by the Law is the knowledge of sin.” And so the punishment is greater, but that because of the Jew. For the Law accomplished the disclosure of sin to you, but it was your duty then to flee it. Since then you have not fled you have pulled the punishment more sorely on yourself, and the good deed of the Law has been made to you a supply of greater vengeance. Now then having added to their fear, he next brings in the things of grace, as having brought them to a strong desire of the remission of their sins, and says,
Ver. 21. “But now the righteousness of God without the Law is manifested.”
Here he utters a great thing, and such as needed much proof. For if they that lived in the Law not only did not escape punishment, but were even the more weighed down thereby, how without the Law is it possible not only to escape vengeance, but even to be justified? For he has here set down two high points, the being justified, and the obtaining these blessings, without the Law. And this is why he does not say righteousness simply, but the righteousness of God, so by the worthiness of the Person displaying the greater degree of the grace, and the possibility of the promise. For to Him all things are possible. And he does not say, “was given,” but “is manifested,” so cutting away the accusation of novelty. For that which is manifested, is so as being old, but concealed. And it is not this only, but the sequel that shows that this is no recent thing. For after saying, “is manifested,” he proceeds:
“Being witnessed by the Law and the Prophets.”
