The New Testament writers - tell of a first century church lead by the Apostles and holding the Bible , scripture as the infallible standard of truth AND YET also having a great struggle with the fact that the Church itself was the source of many doctrinal errors arising repeatedly. With the warning that after the Apostle's departure even more error would be springing up from within the church.
============================================================
Acts 20:29 I know that after my departure savage wolves will come in among you, not sparing the flock; 30 and from among your own selves men will arise, speaking perverse things to draw away the disciples after them. 31 Therefore, be on the alert,
>>apostasy was to arise from WITHIN the church according to Acts 20
1 Tim 1:3 Just as I urged you upon my departure for Macedonia, to remain on at Ephesus so that you would instruct certain people not to teach strange doctrines, 4 nor to pay attention to myths and endless genealogies, which give rise to useless speculation rather than advance the plan of God, which is by faith, so I urge you now. 5 But the goal of our instruction is love from a pure heart, from a good conscience, and from a sincere faith. 6 Some people have strayed from these things and have turned aside to fruitless discussion, 7 wanting to be teachers of the Law, even though they do not understand either what they are saying or the matters about which they make confident assertions.
18 This command I entrust to you, Timothy, my son, in accordance with the prophecies previously made concerning you, that by them you fight the good fight, 19 keeping faith and a good conscience, which some have rejected and suffered shipwreck in regard to their faith. 20 Among these are Hymenaeus and Alexander, whom I have handed over to Satan, so that they will be taught not to blaspheme.
>>Blasphemers arise from within the church - and are handed over to satan - but not "exterminated" like Lateran IV commanded.
3 John 1
9 I wrote something to the church; but Diotrephes, who loves to be first among them, does not accept what we say. 10 For this reason, if I come, I will call attention to his deeds which he does, unjustly accusing us (Apostles) with malicious words; and not satisfied with this, he himself does not receive the brothers either, and he forbids those who want to do so and puts them out of the church.
>>> "The church" casting out those who believe the Apostles's teaching --
The church predicted as going into apostasy 2 Thess 2 -
2 Thess 2: Now we ask you, brothers and sisters, regarding the coming of our Lord Jesus Christ and our gathering together to Him, 2 that you not be quickly shaken from your composure or be disturbed either by a spirit, or a message, or a letter as if from us, to the effect that the day of the Lord has come. 3 No one is to deceive you in any way! For it will not come unless the apostasy comes first, a
"deduced" by "some" via "Extreme inference" is not the same as "taught by the writer"
So then Paul himself subject to "sola scriptura testing"
"They studied the scriptures daily TO SEE IF those things taught by the apostle Paul - WERE SO" Acts 17:11
Gal 1:6-9 "Though WE (Apostles) or an ANGEL from HEAVEN should teach a different doctrine a different gospel other than has been taught - let him be accursed!" - Gal 1:6-9
>>-- rank means nothing - it is the pure truth , pure doctrine that matters according to the Apostle Paul in Gal 1.
History shows that even Popes accuse fellow popes of being "antichrist" as history show.
IN the NT we see the many errors that they were facing - as coming from within the church of the first century -
Jude 1:
3 Beloved, while I was making every effort to write you about our common salvation, I felt the necessity to write to you appealing that you contend earnestly for the faith that was once for all time handed down to the saints. 4 For certain people have crept in unnoticed, those who were long beforehand marked out for this condemnation, ungodly persons who turn the grace of our God into indecent behavior and deny our only Master and Lord, Jesus Christ.
8 Yet in the same way these people also, dreaming, defile the flesh, reject authority, and speak abusively of angelic majesties. 9 But Michael the archangel, when he disputed with the devil and argued about the body of Moses, did not dare pronounce against him an abusive judgment, but said, “The Lord rebuke you!” 10 But these people disparage all the things that they do not understand; and all the things that they know by instinct, like unreasoning animals, by these things they are destroyed. 11 Woe to them! For they have gone the way of Cain, and for pay they have given themselves up to the error of Balaam, and perished in the rebellion of Korah. 12 These are the ones who are hidden reefs in your love feasts when they feast with you without fear, like shepherds caring only for themselves; clouds without water, carried along by winds; autumn trees without fruit, doubly dead, uprooted; 13 wild waves of the sea, churning up their own shameful deeds like dirty foam; wandering stars, for whom the gloom of darkness has been reserved forever.
>> shepherds in the church teaching false doctrine vs 12
... 16 These are grumblers, finding fault, following after their own lusts; they speak arrogantly, flattering people for the sake of gaining an advantage.
Titus 1:
7 For the overseer (Elder) must be beyond reproach as God’s steward, not self-willed, not quick-tempered, not overindulging in wine, not a bully, not greedy for money, 8 but hospitable, loving what is good, self-controlled, righteous, holy, disciplined, 9 holding firmly the faithful word which is in accordance with the teaching, so that he will be able both to exhort in sound doctrine and to refute those who contradict it.
10 For there are many rebellious people, empty talkers and deceivers, especially those of the circumcision, 11 who must be silenced because they are upsetting whole families, teaching things they should not teach for the sake of dishonest gain.
Instead of NO false doctrine being taught - what we see is tons of false doctrine being taught in the first century church and a great struggle to try and keep it from getting out of hand. How much more so when the apostles themselves had died off.
=============================
The NT writers present the NT age as one of strife and contention and false doctrine arising from WITHIN the church
