The passages I posted above describe what to do about it.

however I don't appreciate the fact that most of these texts did not even address disciplinary measure relating to doctrines.

1 Corinthians
5:9 I wrote unto you in an epistle not to company with fornicators:
5:10 Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world.
5:11 But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.
5:12 For what have I to do to judge them also that are without? do not ye judge them that are within?
5:13 But them that are without God judgeth. Therefore put away from among yourselves that wicked person.

2 Thessalonians
3:6 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.
3:14 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.
3:15 Yet count [him] not as an enemy, but admonish [him] as a brother.

1:7 For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
1:8 Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward.
1:9 Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.
1:10 If there come any unto you, and bring not this doctrine, receive him not into [your] house, neither bid him God speed:
1:11 For he that biddeth him God speed is partaker of his evil deeds.

2 Timothy
4:1 I charge [thee] therefore before God, and the Lord Jesus Christ, who shall judge the quick and the dead at his appearing and his kingdom;
