Yes but it was more systematic than that. See also 2 Thes 2:15,3:16, Matthew 18:15-17, etc.
I’m not sure what your trying to get at.
Matthew 18:15-17 is about a brother being separated from the assembly, but it is after the assembly has heard the matter and responded. A single man or even a few men did not have that authority in direct contradiction to the model today.
2 Thess 2:15 does tell us to stand fast in the doctrines received from Paul, specifically in defense against verse 4
Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
Remember ye not, that, when I was yet with you, I told you these things?
We know this to be specifically about the Anti Christ, and yet is this not the ultimate attitude witnessed in Corporate Christianity to one degree or another? Specifically in the Pastor/Popes that we’re all familiar with.
2 Thess 3 is an even better text for these men. Now we command you, brethren, in the name of our Lord Jesus Christ, that ye
withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he received of us.
For yourselves know how ye ought to follow us:
for we behaved not ourselves disorderly among you;
Neither did we eat any man’s† bread for nought; but wrought with labour and travail night and day, that we might not be chargeable to any of you:
Not because we have not power,
but to make ourselves an ensample unto you to follow us.
For even when we were with you, this we commanded you,
that if any would not work, neither should he eat.
For we hear that
there are some which walk among you disorderly, working not at all, but are busybodies.
This ^^^^^ is the epitome of Corporate Christianity pastors. They work not at all, but think they should have the right to coerce monies from their brethren to compensate them for being busybodies! (Sure, I know they call it ministry, but its really socially funded righteousness). Why should any man be compensated for something we are all called to do as believers? Studying? Visiting the sick and elderly and widows and orphans? Sharing a truth from scripture we found while studying this week? Exhorting your brothers to live holy and righteously? Apparently Paul did all that and more while laboring with his own hands just to prove that this is the standard for influence and authority? in the assembly.
Now them that are such we command and exhort by our Lord Jesus Christ,
that with quietness they work, and eat their own bread.
But ye, brethren, be not weary in well doing.
And if any man obey not our word by this epistle,
note that man, and have no company with him, that he may be ashamed.
My point is that a singular man was never to have the kind of pompous authority that these men usurp and project. Even Paul in his role doesnt exercise this and lived his life as an example to remove any pretense of headship over the assembly that was not Christ.
