Dr. John MacArthur of Grace to You sheds light on how false teachers are to be treated. Having a clear understanding of a person’s error is of the utmost importance, as you will see:
The church at Ephesus had a great beginning. Other churches throughout Asia Minor grew out of it. Yet despite the influence of the apostle Paul’s ministry, the church was never impervious to false teachers. As a result, Paul wrote this epistle to Timothy to remind him of his responsibility to stop false teachers and set things in order in the church. He commanded Timothy to maintain pure teaching and set an example for other churches to follow.
Paul speaks of the necessity of stopping false teachers in verses 3-11. Stopping them demands an understanding of four things: their error, their goal, their motive, and their result.
