If the true belivers hadn't clarified their teaching, the posers would be running the show now.
And the entire church would be full of false teachings.
As it is, though, only the false churches have the false teachings.
The true ones were sactified, but the posers weren't.
Again, posers were trying to gain a foothold in the chiurch, but the true believers were resistant.
You did notice the peril they faced, if they didn't oust the posers.
The mistaken, immature, inconsistent, and in need of correction, show they are posers by their disconnection from the mind of Christ.
Great, ht not all of them were in Christ.
Of course not.
But the devilish cannot coexist with the sanctified.
The Spirit will not allow corrup teachings.
Disagreements occur so the posers can be weeded out.
And the true believers kept out the posers.
Amen.
I trust the Spirit.
You say you trust the Spirit, but the apostles repeatedly told Spirit-filled believers to test, examine, and correct doctrine.
If every doctrinal error automatically proved someone was a "poser," Paul's letters become difficult to explain.
Paul did not tell the Corinthians, "The mistaken ones among you were never sanctified."
He addressed the church as sanctified saints (1 Cor. 1:2) and then rebuked them for divisions, carnality, lawsuits, abuses of the Lord's Supper, and confusion about spiritual gifts.
Likewise, the Galatians had received the Spirit (Gal. 3:2-5), yet Paul warned them that they were being drawn toward error.
His remedy was not to declare all who erred unsaved, but to bring them back to the truth.
The problem with defining every disagreement as evidence of a "poser" is that Scripture itself often addresses believers as believers while correcting their wrong thinking.
Even Peter, a genuine apostle, had to be publicly corrected by Paul in Galatians 2.
Peter's error did not prove he lacked the Spirit.
It proved that Spirit-filled people can act inconsistently with what they know to be true.
I also trust the Spirit.
The question is what the Spirit Himself says in Scripture.
The Spirit inspired commands such as "prove all things" (1 Thess. 5:21), "try the spirits" (1 John 4:1), and the example of the Bereans who searched the Scriptures daily to verify even apostolic teaching (Acts 17:11).
If possessing the Spirit guaranteed perfect interpretation, those commands would be unnecessary.
The biblical pattern is not that every mistaken believer is a poser.
The biblical pattern is that true believers must continually submit their understanding to the Word of God, allowing Scripture to correct them whenever they are wrong.
That is precisely why God gave the church apostles, prophets, evangelists, pastors, and teachers "till we all come" to maturity (Eph. 4:11-13), indicating growth in understanding rather than instant infallibility.
