Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
31:32
Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
31:33
But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
Ezekiel 11:19
And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh:
2Co 3:3 Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.
So Jeremiah gives everyone blanket authority to claim that the Spirit is within them? I don't see Jeremiah saying that someday, man could declare God's previously Laws null and void.
Ezekiel doesn't mention anything about Sola Scriptura. Or doing away with the Written Word of God.
All of your verses, especially 2 Cor 3, could be argued that we don't NEED WRITTEN Scriptures! Are you sure you want to go that far?
I still don't see anything about a small group of men given the power to do away with a Law in the Torah as clear as day - that ALL males are to be circumcised to enter into the People of God. All you have given me is that God would establish a New People who would have the Law written in their hearts. This doesn't do away with or abrogate circumcision, this means that the New People will be given the power to OBEY this Law previously given!
