Identifying and Avoiding False Teachers

False teachers are a big deal in the bible. Here, I’ll answer three important questions about them that ought to help every Christian be on guard against their tricksy ways.

Q1: What is a false teacher?

The apostle Peter has a lot to say about false teachers. So does Jude. It’s possible that Jude had Peter’s second letter and borrowed a lot of his material for his own letter. If you read them, they sound similar! What, exactly, are false teachers? What makes them “false”? Both authors sum it up very simply:

Peter says they “secretly introduce destructive heresies, even denying the Master who bought them …” (2 Pet 2:1).
Jude tells us these bad actors are “ungodly persons who turn the grace of our God into indecent behavior and deny our only Master and Lord, Jesus Christ” (Jude 4).

There you have it. A false teacher is someone who denies, disowns, repudiates, or refuses to believe the truth about Jesus. You could say that every heresy, every false teaching, every lie about the gospel always begins by denying something about who Jesus is and what he’s done for his people. People create fake Jesus in their own image.

People say Jesus never really died.
That he is not God.
That he is not eternal.
That he is not co-equal with the Father.
That he was not conceived by a miracle of the Holy Spirit in Mary’s womb.
That he was not sinless.
That he did not die in our place, as our substitute.
That his death was not a ransom.
That his perfect life and willing sacrifice did not satisfy divine justice.

These lies (and others) keep coming back. Every Easter, a major newspaper trots out an article by some liberal scholar who claims to reveal “the truth” about Jesus. False teachers are alive and well. Peter said they would be: “false prophets also appeared among the [old covenant] people, just as there will also be false teachers among you” (2 Pet 2:1).

Q2: How do we know who Jesus is and what he has done?

If a false teacher is someone who denies some key truth about who Jesus is and what he has done, then what tools has God given us so that we can find out these truths? Very simple—by his message, recorded in the bible, and by the Holy Spirit.

Peter tells us about that, too. He wants us to know, with sure conviction, that we can trust the account he’s given us. He and the other disciples didn’t follow clever fables when they told everyone about Jesus—they literally saw him in his majestic splendor (2 Pet 1:16)! They saw what happened to him on that mountain, when he transformed before them into a figure of blazing white, radiant with pure holiness and heavenly light. Peter heard the Father speak words of affirmation about his eternal Son from the heavenly cloud of glory that surrounded them on that mountaintop (2 Pet 1:17-18).

So, he reminds us, the prophecies from the old covenant have now been made surer and more certain. Events have confirmed them. These prophesies and promises are like a lamp shining in a dark place, guiding us until that day when Jesus returns to be the literal light of the world (2 Pet 1:19). So, know this first of all, Peter says: these prophesies weren’t private intuitions or ramblings people made up—they were messages given by men as they were moved by the Holy Spirit to speak (2 Pet 1:20-21)!

The scripture is the record of God’s message to us, and that message is all about Jesus. The Holy Spirit is the who confirms and interprets the scripture for us—every Christian should read John Calvin’s short explanation of this (see Book 1, ch. 7, from Calvin’s Institutes of the Christian Religion). So, to know the truth about Jesus, we must read about his message in the holy scriptures and trust the Spirit of God to help us understand it all.

Q3: How can I be sure I’m interpreting the scriptures about Jesus the right way?

This immediately raises another important question—how do I know that I (and my church) are putting the puzzle pieces together correctly? How do we know we’re believing the right things about Jesus? How do I know I’m interpreting the scriptures the proper way?

Here is where we must deliberately leave our American individualism behind, and make sure we’re on the same page as the untold millions of our Christian brothers and sisters who have gone before us. Jesus tells us that true believers will hear his voice and follow him (Jn 10:1-4). This means that Christians down the centuries have heard the message of the true Jesus, have followed him, and have written down Spirit-led facts and summaries about what the bible says about the true Jesus.

We find this broad consensus about Christian doctrine in the great creeds and confessions of the early church. This doesn’t mean these documents stand atop holy scripture like an infallible filter. One Baptist scholar memorably said we ought to believe in suprema scriptura, which means the bible is the highest or supreme channel of religious authority.¹ This is good—we believe that “the Holy Scripture is the only sufficient, certain, and infallible rule of all saving knowledge, faith, and obedience …” (2LBCF, 1.1). So, creeds and confessions aren’t filters that interpret the bible for us—but they are guardrails that give us assurance that we haven’t run off the road and into a ditch.

I’m thinking especially of these documents:

The Nicene Creed of 325 A.D. and the Nicene-Constantinople Creed of 381 A.D. These clarified Jesus’ deity and his relationship to the Father. Is Jesus a created being? Is Jesus an angel? If Jesus is God’s “son,” then does this mean he came on the scene later than the Father? If Jesus is God, and the Father is God—are Father and Son one being/substance or two?
The Chalcedonian Creed of 451 A.D. What does it mean that Jesus is both divine and human? Did he stop being divine? Or was he not really a fully human person? What happened to him in the incarnation?

From there, see especially the major creedal documents that give shape to your Christian tradition. Assuming you’re a Protestant Christian, the buffet line goes a bit like this:

Lutherans have the Book of Concord, which consists of the Augsburg Confession, Luther’s small and large catechisms, and some other documents.
Presbyterians have the Westminster Standards, which include the Westminster Confession of Faith, and the Westminster larger and smaller catechisms.
The Reformed have the Three Forms of Unity, which are the Belgic Confession, the Heidelberg catechism, and the Canons of Dort.
Baptists are cantankerous in this regard, so I’ll just select one strand of the Baptist tradition and suggest the Second London Baptist Confession (“2LBCF”) and the Orthodox Catechism.²

I don’t care which flavor of Christian you are—go to your tradition’s confession of faith and read what it says about Jesus. No matter which tradition you consult from my list, they all say the same thing about Jesus—the same truths, the same affirmations, the same Jesus. Read the 2LBCF’s explanation here—it’s not long!

Why do creeds and confessions matter? Why are they good guardrails?

Because we don’t need to reinvent the wheel every generation. God gave the same Holy Spirit to our brothers and sisters in 325 A.D. as he does today. He led them into all truth, too. They believed the gospel, read the scriptures, learned from their church leaders and from one another, and had power on high from the Spirit of God. They wrote down summary statements of the faith. We have what they wrote. We would be fools to toss all that aside and start fresh with a blank sheet of paper.

This means that, if you and your church believe something about Jesus that no credible group has ever believed in the history of the church … then you’re probably wrong. We can consult a record of sorts because we have those creeds and confessions from centuries gone by that tell us what our brothers and sisters in Christ thought about who Jesus is and what he’s done.

How do we avoid false teachers?

They’re tricksy. They don’t wear orange jumpsuits. They preach false things about who Jesus is and what he’s done—they deny the real Jesus. So, we must read the scripture and trust the Holy Spirit to guide us. We make sure we’re on the right track by joining a local church which swims in the broad stream of Christianity that has existed from the beginning—one that doesn’t naively try to re-invent the wheel but appreciates the guardrails of the tradition of which it is a part.

Peter said to: “remember the words spoken beforehand by the holy prophets and the commandment of the Lord and Savior spoken by your apostles” (2 Pet 3:2). We give ourselves assurance that we’re interpreting the prophecies and our Savior’s words the right way if we make sure we’re not contradicting what our brothers and sisters have said for centuries!

Read your tradition’s governing documents. See what they say about Jesus—again, read the 2LBCF’s summary about him here. If your church proclaims no tradition beyond its own statement of faith or that of a niche movement with no meaningful roots in the broad Christian tradition, then you are likely at greater risk of bring tricked by false teachers.
