For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.

People's New Testament

3:10 For even that which was made glorious. The Old Covenant. As the glory of the moon and stars fades out before the glory of the sun, so its glory disappears in a comparison with the exceeding glory of the gospel.

Wesley's Notes

3:10 It hath no glory in this respect, because of the glory that excelleth - That is, none in comparison of this more excellent glory. The greater light swallows up the less.

Jamieson-Fausset-Brown Bible Commentary

10. For even the ministration of condemnation, the law, 2Co 3:7 (which has been glorified at Sinai in Moses' person), has now (English Version translates less fitly, "was made . had") lost its glory in this respect by reason of the surpassing glory (of the Gospel): as the light of the stars and moon fades in the presence of the sun.

Matthew Henry's Concise Commentary

3:1-11 Even the appearance of self-praise and courting human applause, is painful to the humble and spiritual mind. Nothing is more delightful to faithful ministers, or more to their praise, than the success of their ministry, as shown in the spirits and lives of those among whom they labour. The law of Christ was written in their hearts, and the love of Christ shed abroad there. Nor was it written in tables of stone, as the law of God given to Moses, but on the fleshy (not fleshly, as fleshliness denotes sensuality) tables of the heart, Eze 36:26. Their hearts were humbled and softened to receive this impression, by the new-creating power of the Holy Spirit. He ascribes all the glory to God. And remember, as our whole dependence is upon the Lord, so the whole glory belongs to him alone. The letter killeth: the letter of the law is the ministration of death; and if we rest only in the letter of the gospel, we shall not be the better for so doing: but the Holy Spirit gives life spiritual, and life eternal. The Old Testament dispensation was the ministration of death, but the New Testament of life. The law made known sin, and the wrath and curse of God; it showed us a God above us, and a God against us; but the gospel makes known grace, and Emmanuel, God with us. Therein the righteousness of God by faith is revealed; and this shows us that the just shall live by his faith; this makes known the grace and mercy of God through Jesus Christ, for obtaining the forgiveness of sins and eternal life. The gospel so much exceeds the law in glory, that it eclipses the glory of the legal dispensation. But even the New Testament will be a killing letter, if shown as a mere system or form, and without dependence on God the Holy Spirit, to give it a quickening power.

Matthew Henry's Whole Bible Commentary

Verses 6-11

Here the apostle makes a comparison between the Old Testament and the New, the law of Moses and the gospel of Jesus Christ, and values himself and his fellow-labourers by this, that they were able ministers of the New Testament, that God had made them so, v. 6. This he does in answer to the accusations of false teachers, who magnify greatly the law of Moses.

I. He distinguishes between the letter and the spirit even of the New Testament, v. 6. As able ministers of the New Testament, they were ministers not merely of the letter, to read the written word, or to preach the letter of the gospel only, but they were ministers of the Spirit also; the Spirit of God did accompany their ministrations. The letter killeth; this the letter of the law does, for that is the ministration of death; and if we rest only in the letter of the gospel we shall be never the better for so doing, for even that will be a savour of death unto death; but the Spirit of the gospel, going along with the ministry of the gospel, giveth life spiritual and life eternal.

II. He shows the difference between the Old Testament and the New, and the excellency of the gospel above the law. For, 1. The Old-Testament dispensation was the ministration of death (v. 7), whereas that of the New Testament is the ministration of life. The law discovered sin, and the wrath and curse of God. This showed us a God above us and a God against us; but the gospel discovers grace, and Emmanuel, God with us. Upon this account the gospel is more glorious than the law; and yet that had a glory in it, witness the shining of Moses's face (an indication thereof) when he came down from the mount with the tables in his hand, that reflected rays of brightness upon his countenance. 2. The law was the ministration of condemnation, for that condemned and cursed every one who continued not in all things written therein to do them; but the gospel is the ministration of righteousness: therein the righteousness of God by faith is revealed. This shows us that the just shall live by his faith. This reveals the grace and mercy of God through Jesus Christ, for obtaining the remission of sins and eternal life. The gospel therefore so much exceeds in glory that in a manner it eclipses the glory of the legal dispensation, v. 10. As the shining of a burning lamp is lost, or not regarded, when the sun arises and goes forth in his strength; so there was no glory in the Old Testament, in comparison with that of the New. 3. The law is done away, but the gospel does and shall remain, v. 11. Not only did the glory of Moses's face go away, but the glory of Moses's law is done away also; yea, the law of Moses itself is now abolished. That dispensation was only to continue for a time, and then to vanish away; whereas the gospel shall remain to the end of the world, and is always fresh and flourishing and remains glorious.
