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!

Heb 10:29
Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
