A mark of the false teacher is the lack of respect toward authority. The rebellious person must destroy the established authority in order to impose himself upon others.
… who despise authority. Brazen and insolent, they are not afraid to insult the glorious ones, yet even angels, who are much more powerful, do not bring a slanderous judgment against them before the Lord.
2 Peter 2:10b-11 NET
The false teacher dares what even angels will not do. And if he speaks ill of celestial beings, how much more will he insult those whom God has established to exercise authority? This without mentioning hatred shown for the word of God itself.
In both the Old and New Testaments, God’s people show respect for authority. “Fear the LORD, my child, as well as the king, and do not associate with rebels” (Proverbs 24:21). Peter himself wrote in his first letter, “Honor all people, love the family of believers, fear God, honor the king” (1 Peter 2:17).
The false teacher may speak softly, but at one moment or another he will show his rebellion against anyone—man, angel, or God—who disturbs his licentiousness.
