Unpardonable Sin
ConceptThe unpardonable sin is a category the Bible applies to offenses that, in the words of the text itself, "will not be forgiven" — most directly the blasphemy against the Holy Spirit, and, in other passages, a falling away that cannot be renewed to repentance or a "sin leading to death."
The clearest scriptural statement is Jesus' saying in Matthew 12:31–32: "every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men," with the added contrast that a word spoken against the Son of Man will be forgiven while a word against the Holy Spirit "will not be forgiven him, either in this age, or in that which is to come." Luke 12:10 records the same contrast in shorter form. As a matter of language, the Greek word behind "blasphemy" (blasphēmia) refers to defaming or abusive speech rather than to a private thought, and the Matthew saying begins with "Therefore," which links it to the exchange that immediately precedes it in the narrative.
Two further New Testament passages are commonly grouped with this one, though their wording is different. Hebrews 6:4–6 describes people "once enlightened" who "tasted of the heavenly gift" and "were made partakers of the Holy Spirit" and then "fell away," and concludes that "it is impossible to renew them again to repentance." First John 5:16–17 distinguishes a "sin not leading to death," for which prayer is encouraged, from "sin leading to death," about which the writer says he does not say one should make request. The Old Testament likewise records judgments declared to stand: the wilderness generation is told "you shall not come into the land" (Numbers 14:30), must bear forty years for forty days and "will know my alienation" (Numbers 14:34), and the account of 2 Kings 24:4 says that because Jerusalem was filled with innocent blood, "Yahweh would not pardon."
How these passages relate to one another is a point of real and longstanding disagreement among Christians. Catholic and Orthodox teaching has generally read 1 John 5:16–17 through a distinction between mortal and lesser sin, and has treated the blasphemy of Matthew 12 as a settled refusal of the Spirit's manifest work rather than a single careless word; Reformed and evangelical readers have often concentrated on Hebrews 6:4–6, differing among themselves over whether it describes genuine believers or only outward profession; Arminian and Wesleyan writers have frequently taken that passage as a real possibility for a believer who turns away fully, while others read it as a warning that itself guards against the falling it describes. One common pastoral reading, offered as interpretation rather than as the text's own statement, holds that persistent fear of having committed this sin is itself evidence of the Spirit's continuing work in a person.
