While studying the different gifts of the Spirit I came across the following (2 Corinthians 3:7-9 NET):

But if the ministry (διακονία)^[1] that produced death – carved in letters on stone tablets – came with glory, so that the Israelites could not keep their eyes fixed on the face of Moses because of the glory of his face (a glory which was made ineffective), how much more glorious will the ministry (διακονία) of the Spirit be?  For if there was glory in the ministry (διακονίᾳ) that produced condemnation, how much more does the ministry (διακονία) that produces righteousness excel in glory!

I can’t help but ask, what if the glory of the ministry (διακονίᾳ) that produces righteousness is made ineffective (καταργουμένην, a form of καταργέω)^[2] by the religious mind?  The note on made ineffective in the NET reads: “Or ‘which was transitory.’ Traditionally this phrase is translated as ‘which was fading away.’ The verb καταργέω in the corpus Paulinum uniformly has the meaning ‘to render inoperative, ineffective’; the same nuance is appropriate here. The glory of Moses’ face was rendered ineffective by the veil Moses wore. For discussion of the meaning of this verb in this context, see S. J. Hafemann, Paul, Moses, and the History of Israel (WUNT 81), 301-13. A similar translation has been adopted in the two other occurrences of the verb in this paragraph in vv. 11 and 13.”

So, if verse 7 means that the “glory of Moses’ face was rendered ineffective by the veil Moses wore,” Paul expanded that meaning in verse 10: For indeed, what had been glorious [the ministry that produced condemnation] now has no glory because of the tremendously greater glory of what replaced it^[3] [the ministry that produces righteousness].  Paul continued (2 Corinthians 3:11, 12 NET):

For if what was made ineffective (καταργούμενον, another form of καταργέω) came with glory, how much more has what remains (μένον, a form of μένω)^[4] come in glory!  Therefore, since we have such a hope, we behave with great boldness, and not like Moses who used to put a veil over his face to keep the Israelites from staring at the result of the glory that was made ineffective (καταργουμένου, another form of καταργέω).

The Greek word translated remains is μένον a form of μένω, as is μένει in, And now these three remain (μένει, another form of μένω): faith, hope, and love.  But the greatest of these is love.^[5]  It is easy to see why some translators related the forms of καταργέω in 2 Corinthians 3 to those in 1 Corinthians 13 (vv. 8, 10, 11; set aside, NET) and rendered them as passing away.  But the word μένον is also found in, The one on whom you see the Spirit descending and remaining (μένον) – this is the one who baptizes with the Holy Spirit.^[6]

So it is also easy to see why other translators related what Paul said about the law, the ministry that produced condemnation, and the ministry of the Spirit, the ministry that produces righteousness, to Romans:  For God achieved what the law could not do because it was weakened (ἠσθένει, a form of ἀσθενέω)^[7] through the flesh.  By sending his own Son in the likeness of sinful flesh and concerning sin, he condemned sin in the flesh, so that the righteous requirement of the law may be fulfilled in us, who do not walk according to the flesh but according to the Spirit.^[8]

It also makes sense then to relate this weakness through the flesh to the forms of καταργέω in 2 Corinthians 3 and render them as made ineffective (the law was weakened through the flesh to the point that it was made ineffective as far as righteousness is concerned).  This makes even more sense if the writing of 2 Corinthians followed the writing of Romans sequentially rather than directly after 1 Corinthians.

Moses…put a veil over his face to keep the Israelites from staring at the result (τέλος)^[9] of the glory that was made ineffective,^[10] Paul wrote.  In one sense he referred to the basic facts of Exodus 34:29-33 (NET):

Now when Moses came down from Mount Sinai with the two tablets of the testimony in his hand – when he came down from the mountain, Moses did not know that the skin of his face shone while he talked with him.  When Aaron and all the Israelites saw Moses, the skin of his face shone; and they were afraid to approach him.  But Moses called to them, so Aaron and all the leaders of the community came back to him, and Moses spoke to them.  After this all the Israelites approached, and he commanded them all that the Lord had spoken to him on Mount Sinai.  When Moses finished speaking with them, he would put a veil on his face.

So the result that the Israelites were kept from staring at was the glowing skin of Moses’ face.  There was another meaning to Paul’s metaphor as well.  But their minds were closed, He continued.  For to this very day, the same veil remains when they hear the old covenant read.^[11] Here, the result or end that the veil keeps people from staring intently at is the fact that the law is the ministry that produced condemnation.  For the law brings wrath…^[12]  For no one is declared righteous before him by the works of the law, for through the law comes the knowledge of sin.^[13]  [The veil] has not been removed because only in Christ is it taken away (καταργεῖται, another form of καταργέω).^[14]  My mind was also closed when I tried to pass myself off as in Christ (ἐν Χριστῷ) while striving to make myself righteous by keeping the law.

But until this very day, Paul continued, whenever Moses is read, a veil lies over their minds, but when one turns to the Lord, the veil is removed.  Now the Lord is the Spirit, and where the Spirit of the Lord is present, there is freedom.  And we all, with unveiled faces reflecting the glory of the Lord, are being transformed into the same image from one degree of glory to another, which is from the Lord, who is the Spirit.^[15]

In my case the Lord was faithful even when I was not; If we are unfaithful, he remains faithful, since he cannot deny himself.^[16]  And perhaps I should let it go at that.  But I still wonder, if I had remained faithless, or while I persisted in my faithlessness, did I give Him cause to show mercy to demons or fallen angels, since He was and remains faithful to me?

Notice therefore the kindness and harshness of God – harshness toward those who have fallen, but God’s kindness toward you, provided you continue in his kindness; otherwise you also will be cut off.  And even they – if they do not continue in their unbelief – will be grafted in, for God is able to graft them in again.  For if you were cut off from what is by nature a wild olive tree, and grafted, contrary to nature, into a cultivated olive tree, how much more will these natural branches be grafted back into their own olive tree?^[17]

For the gifts and the call of God are irrevocable.  Just as you were formerly disobedient to God, but have now received mercy due to their disobedience, so they too have now been disobedient in order that, by the mercy shown to you, they too may now receive mercy.  For God has consigned all people [the qualifier “people” is not literally in the text though “these” (τοὺς) is] to disobedience so that he may show mercy to them all.^[18]
