Articulus I
Whether the Old Law Contains Only One Precept?
Arg. 1 Objection 1
Ad primum sic proceditur. Videtur quod in lege veteri non contineatur nisi unum praeceptum. Lex enim est nihil aliud quam praeceptum, ut supra habitum est. Sed lex vetus est una. Ergo non continet nisi unum praeceptum.
It would seem that the Old Law contains but one precept. Because a law is nothing else than a precept, as stated above (Q. 90, AA. 2, 3). Now there is but one Old Law. Therefore it contains but one precept.
Arg. 2 Objection 2
Praeterea, apostolus dicit, Rom. XIII, si quod est aliud mandatum, in hoc verbo instauratur, diliges proximum tuum sicut teipsum. Sed istud mandatum est unum. Ergo lex vetus non continet nisi unum mandatum.
Further, the Apostle says (Rom. 13:9): "If there be any other commandment, it is comprised in this word: Thou shalt love thy neighbor as thyself." But this is only one commandment. Therefore the Old Law contained but one commandment.
Arg. 3 Objection 3
Praeterea, Matth. VII, dicitur, omnia quaecumque vultis ut faciant vobis homines, et vos facite illis, haec est enim lex et prophetae. Sed tota lex vetus continetur in lege et prophetis. Ergo tota lex vetus non habet nisi unum praeceptum.
Further, it is written (Matt. 7:12): "All things . . . whatsoever you would that men should do to you, do you also to them. For this is the Law and the prophets." But the whole of the Old Law is comprised in the Law and the prophets. Therefore the whole of the Old Law contains but one commandment.
Sed contra On the contrary
Sed contra est quod apostolus dicit, ad Ephes. II, legem mandatorum decretis evacuans. Et loquitur de lege veteri, ut patet per Glossam ibidem. Ergo lex vetus continet in se multa mandata.
On the contrary, The Apostle says (Eph. 2:15): "Making void the Law of commandments contained in decrees": where he is referring to the Old Law, as the gloss comments, on the passage. Therefore the Old Law comprises many commandments.
Respondeo I answer that
Respondeo dicendum quod praeceptum legis, cum sit obligatorium, est de aliquo quod fieri debet. Quod autem aliquid debeat fieri, hoc provenit ex necessitate alicuius finis. Unde manifestum est quod de ratione praecepti est quod importet ordinem ad finem, inquantum scilicet illud praecipitur quod est necessarium vel expediens ad finem. Contingit autem ad unum finem multa esse necessaria vel expedientia. Et secundum hoc possunt de diversis rebus dari praecepta inquantum ordinantur ad unum finem. Unde dicendum est quod omnia praecepta legis veteris sunt unum secundum ordinem ad unum finem, sunt tamen multa secundum diversitatem eorum quae ordinantur ad finem illum.
I answer that, Since a precept of law is binding, it is about something which must be done: and, that a thing must be done, arises from the necessity of some end. Hence it is evident that a precept implies, in its very idea, relation to an end, in so far as a thing is commanded as being necessary or expedient to an end. Now many things may happen to be necessary or expedient to an end; and, accordingly, precepts may be given about various things as being ordained to one end. Consequently we must say that all the precepts of the Old Law are one in respect of their relation to one end: and yet they are many in respect of the diversity of those things that are ordained to that end.
Ad 1 Reply to Objection 1
Ad primum ergo dicendum quod lex vetus dicitur esse una secundum ordinem ad finem unum, et tamen continet diversa praecepta, secundum distinctionem eorum quae ordinat ad finem. Sicut etiam ars aedificativa est una secundum unitatem finis, quia tendit ad aedificationem domus, tamen continet diversa praecepta, secundum diversos actus ad hoc ordinatos.
The Old Law is said to be one as being ordained to one end: yet it comprises various precepts, according to the diversity of the things which it directs to the end. Thus also the art of building is one according to the unity of its end, because it aims at the building of a house: and yet it contains various rules, according to the variety of acts ordained thereto.
Ad 2 Reply to Objection 2
Ad secundum dicendum quod, sicut apostolus dicit, I ad Tim. I, finis praecepti caritas est, ad hoc enim omnis lex tendit, ut amicitiam constituat vel hominum ad invicem, vel hominis ad Deum. Et ideo tota lex impletur in hoc uno mandato, diliges proximum tuum sicut teipsum, sicut in quodam fine mandatorum omnium, in dilectione enim proximi includitur etiam Dei dilectio, quando proximus diligitur propter Deum. Unde apostolus hoc unum praeceptum posuit pro duobus quae sunt de dilectione Dei et proximi, de quibus dicit dominus, Matth. XXII, in his duobus mandatis pendet omnis lex et prophetae.
As the Apostle says (1 Tim. 1:5), "the end of the commandment is charity"; since every law aims at establishing friendship, either between man and man, or between man and God. Wherefore the whole Law is comprised in this one commandment, "Thou shalt love thy neighbor as thyself," as expressing the end of all commandments: because love of one's neighbor includes love of God, when we love our neighbor for God's sake. Hence the Apostle put this commandment in place of the two which are about the love of God and of one's neighbor, and of which Our Lord said (Matt. 22:40): "On these two commandments dependeth the whole Law and the prophets."
Ad 3 Reply to Objection 3
Ad tertium dicendum quod, sicut dicitur in IX Ethic., amicabilia quae sunt ad alterum, venerunt ex amicabilibus quae sunt homini ad seipsum, dum scilicet homo ita se habet ad alterum sicut ad se. Et ideo in hoc quod dicitur, omnia quaecumque vultis ut faciant vobis homines, et vos facite illis, explicatur quaedam regula dilectionis proximi, quae etiam implicite continetur in hoc quod dicitur, diliges proximum tuum sicut teipsum. Unde est quaedam explicatio istius mandati.
As stated in Ethic. ix, 8, "friendship towards another arises from friendship towards oneself," in so far as man looks on another as on himself. Hence when it is said, "All things whatsoever you would that men should do to you, do you also to them," this is an explanation of the rule of neighborly love contained implicitly in the words, "Thou shalt love thy neighbor as thyself": so that it is an explanation of this commandment.
