Here Peter begins describing the false teachers about which he is warning his readers. First, Peter expresses disdain about their nature, comparing them to wild (and irrational) animals whose purpose is only to be caught and destroyed. Second, their actions are based on ignorance, criticizing and demeaning when they have no real knowledge of a matter. He argues that such actions will eventually be the cause of their own ruin, “will utterly perish in their own corruption” (12).
Third, their evil actions will receive “the wages of unrighteousness” (13). As Paul noted, the “wages of sin” is spiritual death (cf. Romans 6:23). Fourth, they are stains, “spots and blemishes” that sully what otherwise should be pure and white “with you” (13).
Fifth, they are unfaithful, here described as having “eyes of adultery.” They not only continually sin, but are guilty of “enticing” others. Sixth, and finally, they are covetous (greedy desire).
