My point was that just because you see the word "church" in scripture, it does not necessarily means its the Body of Christ.
And I never said every assembly is a new testament church.
The BOC is a church true, but there are other churches in scripture that are not the BOC
When I use the Body of Christ for certain I mean the church universal.
When I use the plural "churches" I mean the local expression of the universal church.
If I preach that my wife has long hair,
and you preach that your wife has long hair.
Does it follow that my wife is your wife?
Your point that for Paul to preach the gospel of grace was not
necessarily his preaching of the gospel of the kingdom is nonsensical.
I don't see any clever way to salvage that error. Its just wrong headed. I would say it is too shortsighted.
The relationship between the new testament church life and the discipline of
living under the King's administration is too interrelated.
The kingdom of the heavens in the church age is a matter of submission to Christ's administration
not only as the Head of the Body but the King eternal, immortal, invisible - the only wise God.
Now to the King of the ages, incorruptible, invisible, the only God, be honor and glory forever and ever. Amen. (1 Tim. 1:17)
Those who the Lord deems have well lived in the kingdom of the heavens in the church life as overcoming ones
He will grant reward openly and visibly in glory in the manistation of that kingdom in the thousand year millinnium.
So Paul, for example, awaited a crown of righteousness to co-reign with Christ at His return.
He says he kept the faith, he ran the race. Therefore he expected the open reward to reignat Christ's manifestation.
I have fought the good fight; I have finished the course; I have kept the faith.
Henceforth there is laid up for me the crown of righteousness, with which the Lord, the righteous Judge, will recompense me in that day, and not only me but also all those who have loved His appearing. (2 Tim. 4:7,8)
And it is not only because he was an Israelite. He speaks to the Roman Christians who were Gentiles as Gentiles.
But I am speaking to you, the Gentiles. Inasmuch therefore as I am an apostle of the Gentiles, I glorify my ministry, (Rom. 11:13)
Yet to these Gentile members of the Body of Christ Paul says what the kingdom of God IS, presently, all things being normal.
Therefore do not let your good be slandered;
For the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit. (Rom. 14:16,17)
1.) He is speaking to the Gentile members of the Body of Christ, the church.
2.) He is teaching them what the kingdom of God
IS in this present age if they are normal about being under Christ's administration.
