- Those who pervert grace incurred the censure of Jude
- Paul’s warning about vicious wolves (false teachers) in his farewell message to the church elders at Ephesus
- Paul’s charge to young Timothy to preserve sound doctrine amid “feel good” teaching that tickles itching ears
“So guard yourselves and God’s people. Feed and shepherd God’s flock—his church, purchased with his own blood—over which the Holy Spirit has appointed you as elders. I know that false teachers, like vicious wolves, will come in among you after I leave, not sparing the flock. Even some men from your own group will rise up and distort the truth in order to draw a following” (Acts 20: 28-30).
To recap, leaders need to uphold sound doctrine, identify heresy and rebuke it. They have to make sure that the truth is well communicated to the flock.
