Hebrews 7:18

Ver. 18 . “For there is verily” (he says) “a disannulling of the commandment going before, for the weakness and unprofitableness thereof.” Here the Heretics press on. But listen attentively. He did not say “for the evil,” nor, “for the viciousness,” but “for the weakness and unprofitableness [thereof],” yea and in other places also he shows the weakness; as when he says “In that it was weak through the flesh.” ( Rom. viii. 3 .) [The law] itself then is not weak, but we.

[4.] ( Ver. 6 ) “But now hath He obtained a more excellent ministry, by how much also He is the Mediator of a better covenant.” Thou seest (he means) how much better is the one ministration than the other, if one be an example and type, and the other truth [reality]. But this did not profit the hearers, nor cheer them. Therefore he says what especially cheered them: “Which was established upon better promises.” Having raised them up by speaking of the place, and the priest, and the sacrifice, he then sets forth also the wide difference of the covenant, having also said before that it was “weak and unprofitable.” (See Heb. vii. 18 .)

And observe what safeguards he lays down, when intending to find fault with it. For in the former place after saying, “according to the power of an endless life” ( Heb. vii. 16 ), he then said that “there is a disannulling of the commandment going before” ( Heb. vii. 18 ); and then after that, he set forth something great, saying, “by which we draw nigh unto God.” ( Heb. vii. 19 .) And in this place, after leading us up into Heaven, and showing that instead of the temple, we have Heaven, and that those things were types of ours, and having by these means exalted the Ministration [of the New Covenant], he then proceeds suitably to exalt the priesthood.

The New then has not simply caused the old to cease, but because it had become aged, as it was not [any longer] useful. On this account he said, “for the weakness and unprofitableness thereof” ( Heb. vii. 18 ), and, “the law made nothing perfect” ( Heb. vii. 19 ); and that “if the first had been faultless, then should no place have been sought for the second.” ( Heb. viii. 7 .) And “faultless”; that is, useful; not as though it [the old Covenant] was obnoxious to any charges, but as not being sufficient. He used a familiar form of speech. As if one should say, the house is not faultless, that is, it has some defect, it is decayed: the garment is not faultless, that is, it is coming to pieces. He does not therefore here speak of it as evil, but only as having some fault and deficiency.

Whoever therefore climbs this height of evangelical perfection, is at once raised by the merits of such virtue above every law, and disregarding as trivial all that is commanded by Moses, recognizes that he is only subject to the grace of the Saviour, by whose aid he knows that he attained to that most exalted condition. Therefore sin has no dominion over him, “because the love of God, which is shed abroad in our hearts by the Holy Ghost which is given to us,” shuts out all care for everything else, and can neither desire what is forbidden, or disregard what is commanded, as its whole aim and all its desire is ever fixed on divine love, and to such an extent is it not caught by the delights of worthless things, that it actually does not take advantage of those things which are permitted. …
