Footnotes
αὐτοκατάκριτος (autokatakritos) is a hapax legomenon—appearing only here in the entire NT—meaning "self-condemned": the divisive person's own conduct pronounces the verdict against themselves without any external judge needed. ἐξέστραπται is a Greek perfect passive—"has been twisted/turned inside out"—indicating not a momentary lapse but a completed moral inversion with ongoing consequences.
