First and Second Corinthians
Dealing with False Teachers
Lesson #12 for September 19, 2026
Scriptures: 2 Corinthians 10:1-17; 11:1-15,22-28; 12:20-21; 13:5; Jeremiah 9:24.
[From the Adult Teachers Sabbath School Bible Study Guide=T-BSG:] Imagine you’re hiking in unfamiliar mountains with a small group. The terrain is rugged, the fog thick, and you’re unsure of the path. Suddenly, a confident man appears. He’s dressed like a park ranger, has a walkie-talkie, and even carries a map. He says, “You’re headed the wrong way. Follow me—I know a shortcut.”
Relieved, the group follows him. He walks with authority, tells stories of past rescues, and seems to know every twist and turn. But after an hour, the path becomes narrower, more dangerous, and nothing looks right. Someone checks his GPS and realizes your guide is not leading you toward safety. He’s leading you deeper into the wilderness.
For sure, he looked the part. He sounded convincing. But he wasn’t a guide—he was a fraud. And the consequences of continuing to follow him could’ve been deadly.
Paul is dealing with this same problem in 2 Corinthians 10–12. False teachers had crept into the church, presenting themselves as apostles, speaking with charisma and authority. But they were preaching a different Jesus and leading people away from the truth.
Paul’s response isn’t just about defending himself. It’s about protecting the church from being led into spiritual danger by impostors who looked and sounded the part but were nothing like the real thing.—T-BSG*158.†‡§
Background for Public Oration in Corinth in the First Century a.d.
[T-BSG:] In the first century, the church in Corinth was a young, diverse community in a wealthy, immoral, and philosophically minded [sic] Greek city. As a major port, Corinth attracted a flood of religious ideas, teachers, and philosophies. In this environment, it was common for popular Greek teachers—especially rhetoricians, philosophers, and Sophists—to make a living by charging wealthy audiences for lectures, private lessons, or mentorship. A teacher’s value was often measured by his fee…. Even Dio Chrysostom criticized such figures, saying, “They are like actors on a stage, performing not for truth, but for silver and applause” (Orations 32.11).
Rhetorical power was often associated with virility and manhood. “Any man who aspired to a position of leadership in the first-century Roman world would have been subject to an almost continuous evaluation of his virility by his auditors and rivals.”—Jennifer Larson, “Paul’s Masculinity,” Journal of Biblical Literature, vol. 123, no. 1 (2004), p. 87.
Against this backdrop, Paul faced opposition from false teachers in Corinth. These Jewish-Christian missionaries, whom Paul mockingly called “super-apostles” (2 Cor. 11:5, 2 Cor. 12:11, ESV), attacked Paul for his lack of speaking skills, his sufferings, and his refusal to charge money—behaviors that, by Greek standards, seemed unimpressive.—T-BSG*159.†‡§ [However, think about Paul’s speech at Mars Hill in Athens!]‡
2 Corinthians 11:5-6: 5I do not think that I am the least bit inferior to those very special so-called “apostles” of yours! 6Perhaps I am an amateur in speaking, but certainly not in knowledge; we have made this clear to you at all times and in all conditions.—American Bible Society. (©1992). The Holy Bible: The Good News Translation®* [GNT] (Today’s English Version) [TEV], Second Edition (2 Corinthians 11:5-6). Philadelphia: American Bible Society [abbreviated as Good News Bible-TEV* or GNB-TEV*].‡
2 Corinthians 12:11b: You are the ones who ought to show your approval of me. For even if I am nothing, I am in no way inferior to those very special “apostles” of yours.—Good News Bible-TEV.* [Paul had been a member of the Sanhedrin.]‡
Boasting in Christ
[From the Adult Sabbath School Bible Study Guide=BSG:] Paul’s use of self-boasting language has intrigued interpreters throughout the centuries. However, self-boasting was a common practice in the ancient world and was controlled by social conventions to avoid offending the audience. Paul knew such conventions, and he followed them. In addition, Paul makes it clear that his way of boasting distinguishes itself from that of the false teachers. He boasts in the Lord (2 Cor. 10:17).—BSG* for Monday.‡§
Jeremiah 9:24: [The Lord says:] “If any want to boast,
they should boast that they know and understand me,
because my love is constant,
and I do what is just and right.
These are the things that please me.”—Good News Bible-TEV.*‡
[BSG:] By quoting this passage from Jeremiah, Paul shows that it is Christ who is in focus—Christ’s love, justice, and righteousness.
In other words, Paul’s boasting focuses on God’s accomplishments in Christ. Thus, his boasting is biblical and, hence, inoffensive. On the other hand, his opponents got into an atmosphere of competitiveness by comparing themselves to one another. This is foolishness (2 Cor. 10:12).—BSG* for Monday, September 14.‡§
[BSG:] In 2 Corinthians 10:14–16, Paul hints that preaching the gospel is the primary focus of his ministry, both in Corinth and in regions beyond Corinth. Paul’s love for Jesus led him to talk constantly about the good news of salvation, found in the death and resurrection of Christ.—BSG* for Monday, September 14.†‡
False Teachers in the Church vs. Teachers Called by God
[BSG:] As if Paul didn’t have enough problems already, another one arose that he had to deal with as well: false teachers in the church. These people were opposed to him and to his work and ministry. Worse, these false teachers had seduced members of Corinth as well. Paul refers to his fight against this problem as a spiritual war. [Those were Judaizers!]
Would that be an exaggeration? Not at all. Paul knew that, ultimately, those people were opposing not him but Christ Himself…. He knew that the message he was commissioned to preach was a matter of life or death, with eternal consequences. And he knew that he had been sent to do it by God Himself: “Paul, called to be an apostle of Jesus Christ through the will of God” (1 Cor. 1:1).
When it comes to false teachings, the church is supposed to act with love but firmness, based on the authority of Scripture. The gospel message must be conserved, unspoiled and pure, in order to give souls the hope of eternity.—BSG* for Sabbath Afternoon, September 12.†‡§
[T-BSG:] The false teachers promoted a more legalistic, works-based gospel, flaunted spiritual experiences, and carried letters of recommendation to boost their standings. [Who would give such letters?] Their influence threatened the purity of the gospel, urging the church to judge leaders by outward success rather than by Christlike humility. Paul deliberately countered this influence by working as a tentmaker (Acts 18:3) and preaching without remuneration (2 Cor. 11:7–9), though some saw these practices as a mark of weakness. Paul reminded the Corinthians that, unlike him, these false teachers were those who make “slaves of you” and take “advantage of you” (2 Cor. 11:20, ESV).—T-BSG*159.†‡§
[BSG:] False teachers must be faced with boldness and confidence (2 Cor. 10:2) but mingled with the gentleness of Christ (2 Cor. 10:1). Jesus once said, “I am gentle and humble in heart” (Matt. 11:29, NIV). However, Jesus also boldly confronted the money changers in the temple by overturning their tables and calling them robbers (Matt. 21:12, 13).—BSG* for Sunday.‡§
Matthew 21:12-13: 12Jesus went into the Temple and drove out all those who were buying and selling there. He overturned the tables of the moneychangers and the stools of those who sold pigeons, 13and said to them, “It is written in the Scriptures that God said, ‘My Temple will be called a house of prayer.’ But you are making it a hideout for thieves!”—Good News Bible-TEV.*
[BSG:] He [Jesus] also called the Pharisees hypocrites and whitewashed tombs right to their faces (Matt. 23:23–27). Like Jesus, Paul also knows that we are in a spiritual war that demands the use of God’s whole armor (Eph. 6:12–17).—BSG* for Sunday, September 13.‡§ [Compare John 8:44!]‡
[BSG:] Unlike the false teachers in Corinth who commended themselves, Paul had been commended and approved by God (2 Cor. 10:12, 18). He was “called to be an apostle of Jesus Christ through the will of God” (1 Cor. 1:1, NKJV). He was faithful to this calling until the end of his life (2 Tim. 4:7).—BSG* for Monday, September 14.‡§
Recognizing False Teachers
[BSG:] The New Testament contains several warnings against false teachers in Christian communities. Jesus Himself warned the disciples about this same thing (Matt. 7:15–20). The apostles also called attention to it (Gal. 1:6–9 [Compare Galatians 2:11-14.], 1 Tim. 6:3–5, 2 Pet. 2:1–3).—BSG* for Tuesday, September 15.‡§
Matthew 7:15-20: [Jesus warned:] 15 “Be on your guard against false prophets; they come to you looking like sheep on the outside, but on the inside they are really like wild wolves. 16You will know them by what they do. Thorn bushes do not bear grapes, and briers do not bear figs. 17A healthy tree bears good fruit, but a poor tree bears bad fruit. 18A healthy tree cannot bear bad fruit, and a poor tree cannot bear good fruit. 19And any tree that does not bear good fruit is cut down and thrown in the fire. 20So then, you will know the false prophets by what they do.”—Good News Bible-TEV.*†‡
Galatians 1:6-9: 6I am surprised at you! In no time at all you are deserting the one who called you by the grace of Christ, and are accepting another gospel. 7Actually, there is no “other gospel,” but I say this because there are some people who are upsetting you and trying to change the gospel of Christ. 8But even if we or an angel from heaven should preach to you a gospel that is different from the one we preached to you, may he be condemned to hell! 9We have said it before, and now I say it again: if anyone preaches to you a gospel that is different from the one you accepted, may he be condemned to hell!—Good News Bible-TEV.*†
2 Corinthians 11:13-15: 13Those men are not true apostles—they are false apostles, who lie about their work and disguise themselves to look like real apostles of Christ. 14Well, no wonder! Even Satan can disguise himself to look like an angel of light! 15So it is no great thing if his servants disguise themselves to look like servants of righteousness. In the end they will get exactly what their actions deserve.—Good News Bible-TEV.*†
[BSG:] Paul exposes the false apostles by saying that they are “deceitful workers, transforming themselves into apostles of Christ” (2 Cor. 11:13, NKJV). They disguise themselves as apostles of Christ, just as “Satan disguises himself as an angel of light” and “his [Satan’s] servants, also, disguise themselves as servants of righteousness” (2 Cor. 11:14, 15, ESV). What a tragic situation: professing servants of Christ working as agents of Satan. Paul concludes his thought by saying that their “end will be according to their works” (2 Cor. 11:15, NKJV).—BSG* for Tuesday.†‡Ω§
[From the writings of Ellen G. White=EGW:] The Lord is guarding his people against a repetition of the errors and mistakes of the past. There have always abounded false teachers who, advocating erroneous doctrines and unholy practises [sic-British spelling], and working upon false principles in a most specious, covered, deceptive manner, have endeavored to deceive, if possible, the very elect. They bind themselves up in their own fallacies. If they do not succeed, because their way becomes hedged by warnings from God, they will change somewhat the features of their work, and the representations they have made, and bring out their plans again under a false showing. They refuse to confess, repent, and believe. Confessions may be made, but no real reformation takes place, and erroneous theories bring ruin upon unsuspecting souls because these souls believe and rely upon the men advocating these theories.—Ellen G. White, The Review and Herald,* January 7, 1904, par. 5.‡ [This followed the Kellogg affair!]‡
[https://egwwritings.org/read?panels=p821.23801&index=0]‡
[EGW:] …. The Lord designs that our opinions shall be put to the test, that we may see the necessity of closely examining the living oracles to see whether or not we are in the faith. Many who claim to believe the truth have settled down at their ease, saying, “I am rich, and increased with goods, and have need of nothing.”—Ellen G. White, The Review and Herald,* December 20, 1892, par. 1; Counsels to Writers and Editors* 36.1.‡

Spiritual Warfare Involving False Teachers
[T-BSG:] Spiritual Warfare: In 2 Corinthians 10:4, Paul emphasizes that the battle he faces is not fought with worldly weapons but with spiritual ones that “have divine power to destroy strongholds” (ESV). This passage highlights the concept of spiritual warfare, in which the enemy is not human or earthly but spiritual in nature—manifested in the forces of darkness and deception that seek to undermine the truth of the gospel. Paul is not referring to physical battles or earthly struggles, but to the unseen battle that believers are engaged in as they strive to live according to God’s truth in a world full of opposing ideologies and false teachings. In 2 Corinthians 11:13, Paul calls attention to the false apostles and their teachings, describing them as “deceitful workmen, disguising themselves as apostles of Christ” (ESV) who distort the gospel and lead others astray….
The phrase “divine power” (ESV), in 2 Corinthians 10:4, highlights the fact that the power behind these spiritual weapons comes from God alone, and they are effective because they align with His divine authority and purpose. Paul’s reference to the destruction of enemy strongholds refers to the dismantling of the deeply entrenched arguments, ideologies, and thought patterns that oppose God’s truth. In the context of his ministry, such dismantling involves confronting false apostles and their teachings that promote “another Jesus” and “a different gospel” (2 Cor. 11:4, ESV). These false apostles use manipulation and deceit to subvert the true message of Christ, and Paul recognizes that such falsehoods create spiritual strongholds in the minds of believers. The strongholds are metaphorical, representing thinking patterns and worldviews that lead to spiritual oppression and keep individuals in bondage to sin and error.—T-BSG* 161.†‡§
[BSG:] In this spiritual warfare, Paul acts in the authority of Christ. This authority, however, aims at edification, not destruction (2 Cor. 10:8). It is easy for spiritual leaders to affirm that they are acting in the authority of God. Nevertheless, they must remember that their authority is given by Christ, and, like Him, they must be meek and humble in heart. Paul’s claim of his Christ-given authority is due to his concern that the Corinthians were listening to the wrong people, thereby risking their loyalty to Christ.
How can we be simultaneously gentle and bold when dealing with false teachers? Why must we be both?—BSG* for Sunday.‡§
Suffering for the Sake of the Gospel
[BSG:] After exposing the false teachers as agents of Satan (2 Cor. 11:1–15), Paul now “plays” their game by boasting a little as a fool might (2 Cor. 11:16–21) so that the Corinthians could see how senseless it was to give ears to the false teachers’ speech. If the Corinthians held them in high regard, Paul deserved higher consideration. His sufferings for the gospel show that he was a faithful servant of Christ (2 Cor. 11:22, 23).—BSG* for Wednesday.‡§ [Paul had been through “war,” and it showed!]‡
2 Corinthians 11:16-28: 16I repeat: no one should think that I am a fool. But if you do, at least accept me as a fool, just so I will have a little to boast of. 17Of course what I am saying now is not what the Lord would have me say; in this matter of boasting I am really talking like a fool. 18But since there are so many who boast for merely human reasons, I will do the same. 19You yourselves are so wise, and so you gladly tolerate fools! 20You tolerate anyone who orders you around or takes advantage of you or traps you or looks down on you or slaps you in the face. 21I am ashamed to admit that we were too timid to do those things!
But if anyone dares to boast about something—I am talking like a fool—I will be just as daring. 22Are they Hebrews? So am I. Are they Israelites? So am I. Are they Abraham’s descendants? So am I. 23Are they Christ’s servants? I sound like a madman—but I am a better servant than they are! I have worked much harder, I have been in prison more times, I have been whipped much more, and I have been near death more often. 24Five times I was given the thirty-nine lashes by the Jews; 25three times I was whipped by the Romans; and once I was stoned. I have been in three shipwrecks, and once I spent twenty-four hours in the water. 26In my many travels I have been in danger from floods and from robbers, in danger from my own people and from Gentiles; there have been dangers in the cities, dangers in the wilds, dangers on the high seas, and dangers from false friends. 27There has been work and toil; often I have gone without sleep; I have been hungry and thirsty; I have often been without enough food, shelter, or clothing. 28And not to mention other things, every day I am under the pressure of my concern for all the churches.—Good News Bible-TEV.*
[BSG:] While Paul’s Jewish credentials are [at least] identical [or exceeded] to those of the false teachers (2 Cor. 11:22) [He had been in the Sanhedrin!], his service to Christ surpasses theirs (2 Cor. 11:23). “Are they ministers of Christ?” he asks. The answer is “I am more.” His labors were more abundant; his imprisonments, more frequent; his beatings, more severe.
But this is not all. His list of sufferings also includes five instances of thirty-nine strokes (2 Cor. 11:24), beatings with rods, stoning, shipwrecks, danger in deep waters (2 Cor. 11:25), danger at journeys, danger from rivers, danger from bandits, danger from countrymen, danger from Gentiles, danger in crowded cities, danger in desolate country, danger at sea, danger from false believers (2 Cor. 11:26), strenuous labors, exhausting toils, sleepless nights, hunger, thirst, food shortage, cold, and nakedness (2 Cor. 11:27). As if that weren’t enough, he still had to deal with mental anguish because of his deep anxiety for the churches (2 Cor. 11:28).
Only a true servant of Christ would be willing to suffer like this for the gospel. If Paul were really to boast about his sufferings, he had much to say. However, the next section of the letter shows that the reason for his boast was based not on what he did for Christ but on what Christ had done for him. Paul knew that God’s power is more visibly displayed in human weakness (2 Cor. 12:9, 10). By giving him a thorn in the flesh (2 Cor. 12:7), [Paul apparently had poor eyesight!] God protected Paul from boasting about his accomplishments. This kept him humble, aware of his weakness, dependent on divine power, and in the condition of receiving more of God’s grace and mercy.
Have you also been suffering for the sake of the gospel? What have you learned from this experience? How can the way Paul dealt with his sufferings help you deal with yours?—BSG* for Wednesday.†‡§
Paul’s Plans
2 Corinthians 12:20-21: 20I am afraid that when I get there I will find you different from what I would like you to be and you will find me different from what you would like me to be. I am afraid that I will find quarreling and jealousy, hot tempers and selfishness, insults and gossip, pride and disorder. 21I am afraid that the next time I come my God will humiliate me in your presence, and I shall weep over many who sinned in the past and have not repented of the immoral things they have done—their lust and their sexual sins.—Good News Bible-TEV.*
2 Corinthians 13:5: Put yourselves to the test and judge yourselves, to find out whether you are living in faith. Surely you know that Christ Jesus is in you?—unless you have completely failed.—Good News Bible-TEV.*
