A man is not to be judged a heretic for speaking or writing an error – we all fall into this group.  A heretic is one who continues in teaching falsehoods that strike at the basics of Christian beliefs.  Stuart Brogden

Many people downplay the importance of doctrine, saying such things as, “All the theology I need is that God is love” or “I just want to follow Jesus.”  But they have a false idea of what doctrine is.  It isn’t boring (at least it isn’t supposed to be).  How do you know how to follow Jesus, or why you should follow Jesus, if you don’t have doctrine?  Why on earth would you commit your life to someone without understanding Him or what He taught? 

And yes, God is love, but that is just one of his attributes and not his complete definition.  And what kind of love does this mean – a sentimental, pampering love or the agape kind of love where you have the long term best interests of the other person at heart and would willingly sacrifice for them? 

There are countless false teachers in our churches today, and they do great damage to individuals and the church.  We must know the truth well so we can spot them.  Here is a great article by Charles Spurgeon about false teachers.  Please read it.

Listed at the bottom of this post are just some of the verses pointing us to the importance of sound doctrine.  Jesus expected the Disciples to understand his teachings. Also, keep in mind that Jesus spent much of his time rebuking the Pharisees for their false teachings, and a major part of the New Testament letters was devoted to corrections of errors in the church.  If Jesus warned against false prophets doesn’t that imply that there are true prophets?

If anyone thinks these verses are taken out of context, please let me know.  Some of my theologically liberal blogging buddies implied as such, saying I had selected them in a “willy nilly” fashion.  However, they provided zero (0) examples.  Perhaps they could start with the first passage, which actually contains the phrase “sound doctrine.”  If I took something out of context it wouldn’t be the first or last time, but I am quite correctable and rarely make the same mistake twice. 

One person mocked me for “actually believing that God cares for something called sound doctrine.”  His position is self-refuting and un-Biblical.  Sound doctrine is merely accurate theological teaching.  Given two choices of God either caring about sound doctrine or not caring, he chose the latter while I chose the former.  If God agrees with him, then he has properly taught God’s view.  But that would mean that God cares about the proper teaching of not caring about proper teaching, and that he seems to think it is important to convey sound doctrine on the point of sound doctrine not being important.  Indeed.  It would also mean that God had to communicate his lack of caring about sound doctrine.  Did He do that in the Bible (where?) or outside it? 

Read the verses – or the whole Bible, for that matter – and decide for yourself if God cares about sound doctrine.

2 Timothy 4:3 For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear.

2 Timothy 2:15 Do your best to present yourself to God as one approved, a workman who does not need to be ashamed and who correctly handles the word of truth.

Acts 20:28-31 Keep watch over yourselves and all the flock of which the Holy Spirit has made you overseers. Be shepherds of the church of God, which he bought with his own blood. I know that after I leave, savage wolves will come in among you and will not spare the flock. Even from your own number men will arise and distort the truth in order to draw away disciples after them. So be on your guard! Remember that for three years I never stopped warning each of you night and day with tears.

Matthew 7:15-20 “Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves. By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles? Likewise every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus, by their fruit you will recognize them.

Matthew 24:4-12 Jesus answered: “Watch out that no one deceives you. For many will come in my name, claiming, ‘I am the Christ, ’ and will deceive many. You will hear of wars and rumors of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come. Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places. All these are the beginning of birth pains. “Then you will be handed over to be persecuted and put to death, and you will be hated by all nations because of me. At that time many will turn away from the faith and will betray and hate each other, and many false prophets will appear and deceive many people. Because of the increase of wickedness, the love of most will grow cold,

Matthew 24:24-27 For false Christs and false prophets will appear and perform great signs and miracles to deceive even the elect—if that were possible. See, I have told you ahead of time. “So if anyone tells you, ‘There he is, out in the desert,’ do not go out; or, ‘Here he is, in the inner rooms,’ do not believe it. For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man.

Romans 1:20-22 For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse. For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools

2 Corinthians 11:12-15 And I will keep on doing what I am doing in order to cut the ground from under those who want an opportunity to be considered equal with us in the things they boast about. For such men are false apostles, deceitful workmen, masquerading as apostles of Christ. And no wonder, for Satan himself masquerades as an angel of light. It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will be what their actions deserve.

Galatians 1:6-10 I am astonished that you are so quickly deserting the one who called you by the grace of Christ and are turning to a different gospel— which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned! As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let him be eternally condemned! Am I now trying to win the approval of men, or of God? Or am I trying to please men? If I were still trying to please men, I would not be a servant of Christ.

Ephesians 4:11-14 It was he who gave some to be apostles, some to be prophets, some to be evangelists, and some to be pastors and teachers, to prepare God’s people for works of service, so that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ. Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of men in their deceitful scheming.

Ephesians 5:6-11 Let no one deceive you with empty words, for because of such things God’s wrath comes on those who are disobedient. Therefore do not be partners with them. For you were once darkness, but now you are light in the Lord. Live as children of light (for the fruit of the light consists in all goodness, righteousness and truth) and find out what pleases the Lord. Have nothing to do with the fruitless deeds of darkness, but rather expose them.

Colossians 2:4 I tell you this so that no one may deceive you by fine-sounding arguments.

Colossians 2:8-12 See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the basic principles of this world rather than on Christ. For in Christ all the fullness of the Deity lives in bodily form, and you have been given fullness in Christ, who is the head over every power and authority. In him you were also circumcised, in the putting off of the sinful nature, not with a circumcision done by the hands of men but with the circumcision done by Christ, having been buried with him in baptism and raised with him through your faith in the power of God, who raised him from the dead.

Colossians 2:18-19 Do not let anyone who delights in false humility and the worship of angels disqualify you for the prize. Such a person goes into great detail about what he has seen, and his unspiritual mind puffs him up with idle notions. He has lost connection with the Head, from whom the whole body, supported and held together by its ligaments and sinews, grows as God causes it to grow.

2 Thessalonians 2:1-4 Concerning the coming of our Lord Jesus Christ and our being gathered to him, we ask you, brothers, not to become easily unsettled or alarmed by some prophecy, report or letter supposed to have come from us, saying that the day of the Lord has already come. Don’t let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness is revealed, the man doomed to destruction. He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s temple, proclaiming himself to be God.

1 Timothy 6:20-21 Timothy, guard what has been entrusted to your care. Turn away from godless chatter and the opposing ideas of what is falsely called knowledge, which some have professed and in so doing have wandered from the faith. Grace be with you.

2 Timothy 3:1-7 But mark this: There will be terrible times in the last days. People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents, ungrateful, unholy, without love, unforgiving, slanderous, without self-control, brutal, not lovers of the good, treacherous, rash, conceited, lovers of pleasure rather than lovers of God— having a form of godliness but denying its power. Have nothing to do with them. They are the kind who worm their way into homes and gain control over weak-willed women, who are loaded down with sins and are swayed by all kinds of evil desires, always learning but never able to acknowledge the truth.

2 Timothy 3:12-14 In fact, everyone who wants to live a godly life in Christ Jesus will be persecuted, while evil men and impostors will go from bad to worse, deceiving and being deceived. But as for you, continue in what you have learned and have become convinced of, because you know those from whom you learned it,

2 Peter 1:16 We did not follow cleverly invented stories when we told you about the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty.

2 Peter 1:20-2:3 Above all, you must understand that no prophecy of Scripture came about by the prophet’s own interpretation. For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit. But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them—bringing swift destruction on themselves. Many will follow their shameful ways and will bring the way of truth into disrepute. In their greed these teachers will exploit you with stories they have made up. Their condemnation has long been hanging over them, and their destruction has not been sleeping.

1 John 4:1-3 Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world. This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God, but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world.

1 Corinthians 1:18-25 For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. For it is written: “I will destroy the wisdom of the wise; the intelligence of the intelligent I will frustrate.” Where is the wise man? Where is the scholar? Where is the philosopher of this age? Has not God made foolish the wisdom of the world? For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe. Jews demand miraculous signs and Greeks look for wisdom, but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles, but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God. For the foolishness of God is wiser than man’s wisdom, and the weakness of God is stronger than man’s strength.

1 Thessalonians 5:6-11 So then, let us not be like others, who are asleep, but let us be alert and self-controlled. For those who sleep, sleep at night, and those who get drunk, get drunk at night. But since we belong to the day, let us be self-controlled, putting on faith and love as a breastplate, and the hope of salvation as a helmet. For God did not appoint us to suffer wrath but to receive salvation through our Lord Jesus Christ. He died for us so that, whether we are awake or asleep, we may live together with him. Therefore encourage one another and build each other up, just as in fact you are doing.

Jude 3-4 Dear friends, although I was very eager to write to you about the salvation we share, I felt I had to write and urge you to contend for the faith that was once for all entrusted to the saints. For certain men whose condemnation was written about long ago have secretly slipped in among you. They are godless men, who change the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord.  [Read all of Jude – it is only 25 verses and says a lot about false teachers.]

2 Timothy 2:23-25 Don’t have anything to do with foolish and stupid arguments, because you know they produce quarrels. And the Lord’s servant must not quarrel; instead, he must be kind to everyone, able to teach, not resentful. Those who oppose him he must gently instruct, in the hope that God will grant them repentance leading them to a knowledge of the truth,

Titus 1:9-2:1 He must hold firmly to the trustworthy message as it has been taught, so that he can encourage others by sound doctrine and refute those who oppose it. For there are many rebellious people, mere talkers and deceivers, especially those of the circumcision group. They must be silenced, because they are ruining whole households by teaching things they ought not to teach—and that for the sake of dishonest gain.  . . . Therefore, rebuke them sharply, so that they will be sound in the faith and will pay no attention to Jewish myths or to the commands of those who reject the truth. To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted. They claim to know God, but by their actions they deny him. They are detestable, disobedient and unfit for doing anything good. You must teach what is in accord with sound doctrine.

Deuteronomy 13:1-5 If a prophet, or one who foretells by dreams, appears among you and announces to you a miraculous sign or wonder, and if the sign or wonder of which he has spoken takes place, and he says, “Let us follow other gods” (gods you have not known) “and let us worship them,” you must not listen to the words of that prophet or dreamer. The Lord your God is testing you to find out whether you love him with all your heart and with all your soul. It is the Lord your God you must follow, and him you must revere. Keep his commands and obey him; serve him and hold fast to him. That prophet or dreamer must be put to death, because he preached rebellion against the Lord your God, who brought you out of Egypt and redeemed you from the land of slavery; he has tried to turn you from the way the Lord your God commanded you to follow. You must purge the evil from among you.   

Jeremiah 5:31 The prophets prophesy lies, the priests rule by their own authority, and my people love it this way. But what will you do in the end?

 1 John 4:1 Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.

Jeremiah 14:14 Then the Lord said to me, “The prophets are prophesying lies in my name. I have not sent them or appointed them or spoken to them. They are prophesying to you false visions, divinations, idolatries and the delusions of their own minds.

2 John 7 Many deceivers, who do not acknowledge Jesus Christ as coming in the flesh, have gone out into the world. Any such person is the deceiver and the antichrist.

Romans 16:17-18 I urge you, brothers, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned. Keep away from them. For such people are not serving our Lord Christ, but their own appetites. By smooth talk and flattery they deceive the minds of naive people.

John 8:44-45 You belong to your father, the devil, and you want to carry out your father’s desire. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies. Yet because I tell the truth, you do not believe me! 

2 Corinthians 10:5 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.

1 Timothy 4:16 Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.

Also see Jesus’ messages to the churches in Revelation 2-3 and all the passages where Jesus rebukes the Pharisees for their false teachings.
