The abolishment question is easily answered. The Jesus vs Paul argument.
Jesus: Matt 5:17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
The law will always stand for the unsaved. Paul still used it in Romans to condemn all. Not for the justified, but for the unsaved, 1 Tim 1, same list of creatures found in Rom 1.
So, the question is where, and for whom is it abolished?
Paul: Eph 2:15 by abolishing the law of commandments expressed in ordinances, that he might create in himself one new man in place of the two, so making peace,
Where is it ended, Rom 10:4?
Simple, the cross, for the Christians, where they died to law, to be raised up out of sin, law and flesh. Law ended on the cross, in his body, for the Christian, not for the unsaved, where it will always stand, the way Paul used it in Romans, to kill.
Look where it was abolished. His body, the cross.
Eph 2:14 For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility
Eph 2:16 16 and might reconcile us both to God in one body through the cross, thereby killing the hostility.
"Brothers", he was talking to saved people, not unsaved. The Christians died to law, the body...
Rom 7:4 Likewise, my brothers, you also have died to the law through the body of Christ, so that you may belong to another, to him who has been raised from the dead, in order that we may bear fruit for God.
More..died to law, the cross, that would be the same as the body.
Gal 2:19 For through the law I died to the law, so that I might live to God. 20 I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.
More, the cross...
Col 2:14 by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross.
There we go, abolished for the Christian, no longer under law, but under grace, where sin, law, and flesh, have no dominion, Rom 5:21. Sin does however, have dominion under law, Rom 6:14, because the law is in accordance with the flesh. Sin lived in the Adamic creation, which was brought to full fruition, under law, aroused by law, Rom 7:5, 7:13, but then it was crucified with Christ, Rom 6:6. Then we are raised up like Christ, in a new creation, as Christ is. Christ also died to law, that which he was born under, Gal 4:4.
