False teachers

That there is false teaching in the world around us should come as no surprise. Since “the world around us” is generally understood to mean that which is apart from Christ and the community of believers is clear enough, so apart from Him what kind of teaching would we expect to find? The thing that has Jude writing a letter of this sort, is that these false teachers are within the Body of believers, passing themselves off as followers of Christ, while teaching people to rebel against Him.
