1 Timothy 1:8

The beneficent action of the law, the apostle showed in the passage relating to the Jews, writing thus: “Behold, thou art called a Jew and restest in the law, and makest thy boast in God, and knowest the will of God, and approvest the things that are more excellent, being instructed out of the law, and art confident that thou thyself art a guide of the blind, a light of them who are in darkness, an instructor of the foolish, a teacher of babes, who hast the form of knowledge and of truth in the law.” For it is admitted that such is the power of the law, although those whose conduct is not according to the law, make a false pretence, as if they lived in the law. …

27. All which things having been heard and considered, I am unwilling to contend about words, for that is profitable to nothing but to the subverting of the hearers. But the law is good to edify, if a man use it lawfully; for the end of it “is charity out of a pure heart, and of a good conscience, and of faith unfeigned.” And well did our Master know, upon which two commandments He hung all the Law and the Prophets. And what doth it hinder me, O my God, Thou light of my eyes in secret, while ardently confessing these things, since by these words many things may be understood, all of which are yet true, what, I say, doth it hinder me, should I think otherwise of what the writer thought than some other man thinketh? Indeed, all of us who read endeavour to trace out and to understand that which he whom we read wished to convey; and as we believe him to speak truly, we dare not suppose that …

35. Hearken, O God, Thou best Judge! Truth itself, hearken to what I shall say to this gainsayer; hearken, for before Thee I say it, and before my brethren who use Thy law lawfully, to the end of charity; hearken and behold what I shall say to him, if it be pleasing unto Thee. For this brotherly and peaceful word do I return unto him: “If we both see that that which thou sayest is true, and if we both see that what I say is true, where, I ask, do we see it? Certainly not I in thee, nor thou in me, but both in the unchangeable truth itself, which is above our minds.” When, therefore, we may not contend about the very light of the Lord our God, why do we contend about the thoughts of. …

41. In this diversity of true opinions let Truth itself beget concord; and may our God have mercy upon us, that we may use the law lawfully, the end of the commandment, pure charity. And by this if any one asks of me, “Which of these was the meaning of Thy servant Moses?” these were not the utterances of my confessions, should I not confess unto Thee, “I know not;” and yet I know that those opinions are true, with the exception of those carnal ones concerning which I have spoken what I thought well. However, these words of Thy Book affright not those little ones of good hope, treating few of high things in a humble fashion, and few things in varied ways. …

3. The law, therefore, by teaching and commanding what cannot be fulfilled without grace, demonstrates to man his weakness, in order that the weakness thus proved may resort to the Saviour, by whose healing the will may be able to do what in its feebleness it found impossible. So, then, the law brings us to faith, faith obtains the Spirit in fuller measure, the Spirit sheds love abroad in us, and love fulfils the law. For this reason the law is called a “schoolmaster,” under whose threatenings and severity “whosoever shall call upon the name of the Lord shall be delivered.” But how shall they call on Him in whom they have not believed?” Wherefore unto them that believe and call on Him the quickening Spirit is given, lest the letter without the Spirit should kill them. …

41. Lot also, the brother of Abraham, was just and hospitable in Sodom, and was found worthy to escape the conflagration which prefigured the future judgment; for he was free from all participation in the corruption of the people of Sodom. He was a type of the body of Christ, which in the person of all the saints both groans now among the ungodly and wicked, to whose evil deeds it does not consent, and will at the end of the world be rescued from their society, when they are doomed to the punishment of eternal fire. Lot’s wife was the type of a different class of men, of those, namely, who, when called by the grace of God, look back, instead of, like Paul, forgetting the things that are behind, and looking forward to the things that are before. …

Chapter 8. 9. Wherefore, as the apostle said of the law, "The law is good, if a man use it lawfully," so we may fairly say of baptism, Baptism is good, if a man use it lawfully. And as they who used the law unlawfully could not in that case cause that it should not be in itself good, or make it null and void, so any one who uses baptism unlawfully, either because he lives in heresy, or because he lives the worst of lives, yet cannot cause that the baptism should be otherwise than good, or altogether null and void. And so, when he is converted either to Catholic unity, or to a mode of living worthy of so great a sacrament, he begins to have not another and a lawful baptism, but that same baptism in a lawful manner. …

Chapter 56. 127. Petilianus said: "But even if, as you yourselves suppose, you are following the law of the Lord in purity, let us nevertheless consider the question of the most holy law itself in a legal form. The Apostle Paul says, ‘The law is good, if a man use it lawfully.’ What then does the law say? ‘Thou shalt not kill.’ What Cain the murderer did once, you have often done in slaying your brethren."

Because “for a righteous man the law was not made;” and yet “the law is good, if a man use it lawfully.” Now by connecting together these two seemingly contrary statements, the apostle warns and urges his reader to sift the question and solve it too. For how can it be that “the law is good, if a man use it lawfully,” if what follows is also true: “Knowing this, that the law is not made for a righteous man?” For who but a righteous man lawfully uses the law? Yet it is not for him that it is made, but for the unrighteous. …

But “the precepts of the law are very good,” if we use them lawfully. Indeed, by the very fact (of which we have the firmest conviction) “that the just and good God could not possibly have enjoined impossibilities,” we are admonished both what to do in easy paths and what to ask for when they are difficult. Now all things are easy for love to effect, to which (and which alone) “Christ’s burden is light,”, or rather, it is itself alone the burden which is light. Accordingly it is said, “And His commandments are not grievous;” so that whoever finds them grievous must regard the inspired statement about their “not being grievous” as having been capable of only this meaning, that there may be a state of heart to which they are not burdensome, and he must pray for that disposition which he at present wants, so as to be able to fulfil all that is commanded him. …

He next quotes passages to show that God’s commandments are not grievous. But who can be ignorant of the fact that, since the generic commandment is love (for “the end of the commandment is love,” and “love is the fulfilling of the law”), whatever is accomplished by the operation of love, and not of fear, is not grievous? They, however, are oppressed by the commandments of God, who try to fulfil them by fearing. “But perfect love casteth out fear;” and, in respect of the burden of the commandment, it not only takes off the pressure of its heavy weight, but it actually lifts it up as if on wings. In order, however, that this love may be possessed, even as far as it can possibly be possessed in the body of this death, the determination of will avails but little, unless it be helped by God’s grace through our Lord Jesus Christ. …

10. “Juda is my king: Moab the pot of my hope” ( ver. 7 ). What Juda? He that is of the tribe of Juda. What Juda, but He to whom Jacob himself said, “Juda, thy brethren shall praise thee”? What therefore should I fear, when Juda my king saith, “Fear not them that kill the body”? “Moab the pot of my hope.” Wherefore “pot”? Because tribulation. Wherefore “of my hope”? Because there hath gone before Juda my king.…Moab is perceived in the Gentiles. For that nation was born of sin, that nation was born of the daughters of Lot, who lay with their father drunken, abusing a father. Better were it to have remained barren, than thus to have become mothers. But this was a kind of figure of them that abuse the law. …
