“The law was our guardian until Christ came, in order that we might be justified by faith. But now that faith has come, we are no longer under a guardian.”

Romans 3:19-31
Epistle to the Romans
Context: Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God. Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith. Therefore we conclude that a man is justified by faith without the deeds of the law. Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also: Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
Do we then make void the law through faith? God forbid: yea, we establish the law.

1780s, A Defence of the Constitutions of Government (1787)
Context: A single assembly will never be a steady guardian of the laws, if Machiavel is right, when he says, Men are never good but through necessity: on the contrary, when good and evil are left to their choice, they will not fail to throw every thing into disorder and confusion. Hunger and poverty may make men industrious, but laws only can make them good; for, if men were so of themselves, there would be no occasion for laws; but, as the case is far otherwise, they are absolutely necessary.
