Shared ground
These verses portray a recognizable profile: people driven by defiling desires who also treat authority with contempt. Their posture is not just private; it shows up in speech—bold, self-directed insults aimed at “glorious ones” (glorious ones). That combination (craving + contempt + reckless speech) is presented as a mark of serious moral disorder.
A second clear claim is the contrast with angels. Angels are said to be greater in strength and power, yet they refuse to bring a demeaning, insulting accusation “before the Lord.” The passage assumes that there is a proper place for judgment and that even powerful beings practice restraint.
Where interpretation differs
What “authority” refers to. Some read it mainly as human authority structures (community leaders, masters, rulers). Others read it more broadly as any rightful authority, including spiritual authority.
Who the “glorious ones” are. Some understand them as angelic beings (good angels or heavenly beings generally). Others take them as human “dignitaries” (high-status rulers or leaders). A third option connects them to hostile spiritual powers, with the point being how one speaks even about evil beings.
Who “them” refers to in v.11. Some take “them” to mean the “glorious ones” (angels refuse to accuse these dignitaries in an insulting way). Others take “them” to mean the arrogant teachers (angels won’t hurl insults even against such people, but leave judgment to the Lord).
Why the disagreement exists
The terms are compressed and somewhat general (“authority,” “glorious ones,” “them”), and the immediate context does not explicitly define each referent. English translations also differ (e.g., “dignitaries”), which can push readers toward human leaders or toward heavenly beings. The author’s main thrust—condemning arrogant contempt expressed in slander—remains stable even while details are debated.
What this passage clearly contributes
Explicitly, it condemns a kind of swaggering irreverence: treating rightful authority as beneath you and speaking insultingly about beings/figures that should not be handled casually. By inference from the angel comparison, it presents restraint in accusation as a mark of proper order: if angels, though stronger, do not bring insulting accusations “before the Lord,” then reckless slander is not bravery but presumption (2 Peter 2:10–11).
