1 Timothy, chapter 1
3: As I urged you when I was going to Macedonia, remain at Ephesus that you may charge certain persons not to teach any different doctrine,
8: Now we know that the law is good, if any one uses it lawfully,
9: understanding this, that the law is not laid down for the just but for the lawless and disobedient, for the ungodly and sinners, for the unholy and profane, for murderers of fathers and murderers of mothers, for manslayers,
10: immoral persons, sodomites, kidnapers, liars, perjurers, and whatever else is contrary to sound doctrine,
11: in accordance with the glorious gospel of the blessed God with which I have been entrusted.
1 Timothy, chapter 4
1: Now the Spirit expressly says that in later times some will depart from the faith by giving heed to deceitful spirits and doctrines of demons
6: If you put these instructions before the brethren, you will be a good minister of Christ Jesus, nourished on the words of the faith and of the good doctrine which you have followed.
2 John, chapter 1
9: Any one who goes ahead and does not abide in the doctrine of Christ does not have God; he who abides in the doctrine has both the Father and the Son.
10: If any one comes to you and does not bring this doctrine, do not receive him into the house or give him any greeting
Titus, chapter 1
9: he must hold firm to the sure word as taught, so that he may be able to give instruction in sound doctrine and also to confute those who contradict it.
10: For there are many insubordinate men, empty talkers and deceivers, especially the circumcision party;
11: they must be silenced, since they are upsetting whole families by teaching for base gain what they have no right to teach.
Titus, chapter 2
1: But as for you, teach what befits sound doctrine.
9: Bid slaves to be submissive to their masters and to give satisfaction in every respect; they are not to be refractory,
10: nor to pilfer, but to show entire and true fidelity, so that in everything they may adorn the doctrine of God our Savior.
Ephesians, chapter 4
14: so that we may no longer be children, tossed to and fro and carried about with every wind of doctrine, by the cunning of men, by their craftiness in deceitful wiles.
Hebrews, chapter 6
1: Therefore let us leave the elementary doctrine of Christ and go on to maturity, not laying again a foundation of repentance from dead works and of faith toward God,
Romans, chapter 16
17: I appeal to you, brethren, to take note of those who create dissensions and difficulties, in opposition to the doctrine which you have been taught; avoid them.
