How do we know that false teachers are condemned according to scripture?

The condemnation of false teachers is grounded in multiple scriptural references, particularly in 2 Peter and Jude. Peter draws parallels between the fate of the angels who sinned and the judgment that awaits false teachers. They are described as having been 'cast down to hell' and kept in chains of darkness, symbolizing their ultimate fate and punishment. Furthermore, Jude also speaks of these beings as being reserved for judgment. The emphatic nature of these warnings highlights that just as God judged the wicked in the past, He will assuredly judge those who take up the mantle of teaching while distorting His truth.
