Paul's instructions apply to all churches. I am saying that they are not somehow binding between different churches or directly applicable as instruction to unchurched Christians.
Paul was addressing issues within the church in Corinth.
I am in no way saying Paul's words do not apply to each congregation today. A church should be without division.
But if we want to have one English translation in the English speaking world today then it has to be the NIV as it is the most common English translation today (and has been for a decade). I just think that is overstepping.
If course, you have to remember that mine is a Baptist perspective. Baptists do not view Paul as instructing some collection of churches under a "mother church" or governing body. We believe in the autonomy of the local church.
So while we believe that Paul's words apply, we believe they apply to each church, instructing each individual church how to conduct itself.
The apostles and eye witnesses of the events of which they wrote, the authors of the New Testament, remains to this day the authority of the church. Since the church now has a gentile character, the 13 letters of Paul instructs the church of Jesus Christ, he being distinctly the apostle to the gentiles. For over 18 hundred years there was not a national entity called the nation of Israel or the nation of Judah.. Since 70 AD and the dispersion of the Jews by the Romans those of Jacob have been considered gentiles by God. This is pictured in type by gentile women who were married to Jewish men, like Rebeka, Rahab, Ruth, and five more.
However, during the apostolic era of the church, there was a Jewish church and Paul in Romans says this about them;
Ro 15:15 Nevertheless, brethren, I have written the more boldly unto you in some sort, as putting you in mind, because of the grace that is given to me of God,
16 That I should be the minister of Jesus Christ to the Gentiles, ministering the gospel of God, that the offering up of the Gentiles might be acceptable, being sanctified by the Holy Ghost.
17 I have therefore whereof I may glory through Jesus Christ in those things which pertain to God.
18 For I will not dare to speak of any of those things which Christ hath not wrought by me, to make the Gentiles obedient, by word and deed,
Ro 15:25 But now I go unto Jerusalem to minister unto the saints.
26 For it hath pleased them of Macedonia and Achaia to make a certain contribution for the poor saints which are at Jerusalem.
27 It hath pleased them verily; and their debtors they are. For if the Gentiles have been made partakers of their spiritual things, their duty is also to minister unto them in carnal things.
This passage should convince you that Paul's gentile apostleship was not to individual churches but to gentiles. Now saved men are not Jews or gentiles but the singular church of Jesus Christ.
