I love Tim Challies post on the Seven Marks of a False Teacher. Every Christian should send the list to their pastor’s as a reminder that a pastor is not to be entertainer, but a shepherd.
Here are the first few points:
False teachers are man pleasers. What they teach is meant to please the ear more than profit the heart. They tickle the ears of their followers with flattery and all the while they treat holy things with wit and carelessness rather than reverence and awe. This contrasts sharply with a true teacher of the Word who knows that he is answerable to God and who is therefore far more eager to please God than men. As Paul would say, “But just as we have been approved by God to be entrusted with the gospel, so we speak, not to please man, but to please God who tests our hearts” (1 Thes. 2:4).
False teachers save their harshest criticism for God’s most faithful servants. False teachers criticize those who teach the truth, and save their sharpest criticism for those who hold most steadfastly to what is true. We see this in many places in the Bible, such as when Korah and his friends rose up against Moses and Aaron (Num. 16:3) and when Paul’s ministry was threatened and undermined by those critics who said that while his words were strong, he himself was weak and unimportant (2 Cor. 10:10). We see it most notably in the vicious attacks of the religious authorities against Jesus. False teachers continue to rebuke and belittle God’s faithful servants today. Yet, as Augustine declared, “He that willingly takes from my good name, unwillingly adds to my reward.”
False teachers teach their own wisdom and vision. This was certainly true in the days of Jeremiah when God would say, “The prophets are prophesying lies in my name. I did not send them, nor did I command them or speak to them. They are prophesying to you a lying vision, worthless divination, and the deceit of their own minds” (Jer. 14:14). And today, too, false teachers teach the foolishness of mere men instead of teaching the deeper, richer wisdom of God. Paul knew, “the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths” (2 Tim. 4:3).
