I do, in fact, object -- quite strongly -- to the things that Jeremiah Wright has said.
And, even though I am not a member of any church within the United Church of Christ denomination, I object to many of the things they teach.
But simply because my own denomination is a part of the NCC does not mean that I, or for that matter most of the members of the church I attend, agreed with everything the United Church of Christ says. Or with what Jeremian Wright says.
That would be sort of like saying, during the 1990's, that those of us in the USA agreed with everything Bill Clinton said or did.
I didn't agree with what Bill Clinton said and did during his presidency. But I did not leave the USA.
God's blessings on your efforts to wrest your church away from the NCC.
An entirely different matter. The USA isn't Jesus Christ's blood bought Church, and we aren't commanded to leave our nation if it's beliefs and acts are contrary to sound bible doctrine. The scripture below is a guide as to what we should do in the matter of membership in an apostate church, but it isn't in any way applicable to our citizenship in the USA.
2Cr:6:14Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
2Cr 6:15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
2Cr 6:16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
2Cr 6:17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you
