There's no question that the entire law (including the 10 commandments) has been abolished.
But if the ministration of death, written [and] engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which [glory] was to be done away: 2 Corinthians 3:7
Done away/Abolish
G2673 καταργέω katargeo
1. to make entirely idle
GREEK-ENGLISH LEXICON of the NEW TESTAMENT BASED ON SEMANTIC DOMAINS
76.26 καταργέωc: to render ineffective the power or force of something—‘to invalidate, to abolish, to cause not to function.’ τὸν νόμον τῶν ἐντολῶν ἐν δόγμασιν καταργήσας ‘to abolish the Law of commandments consisting of regulations’ Eph 2:15;
This is the same Greek word used in Ephesians 2:15
For [Christ] is our peace, who has made both [Jew and gentile] one, destroying the middle wall of the barrier, the enmity, in his flesh; having abolished the law of commandments contained in ordinances; that of the two he should make in himself one new man, so making peace. Ephesians 2:14-15
It's a completely different word than that used in Matthew 5:17
Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. Matthew 5:17
destroy
G2647 καταλύω kataluo
1. to loosen down (disintegrate)
2. (by implication) to demolish
GREEK-ENGLISH LEXICON of the NEW TESTAMENT BASED ON SEMANTIC DOMAINS
20.54 καταλύωa; καθαιρέωc; καθαίρεσιςa, εως f: to destroy completely by tearing down and dismantling—‘to destroy, to tear down, destruction.’
καταλύωa: οὐκ ἀφεθήσεται λίθος ἐπὶ λίθῳ ὃς οὐ καταλυθήσεται ‘there will not be one stone left on another which will not be torn down’ Lk 21:6.
So the law hasn't been destroyed, but it's authority has been abolished. Now Christ's law is authoritative, and all righteousness required by every jot and tittle of the law of Moses is produced when it is obeyed.
