1 John 5:16

Verse 16. A sin which is not unto death] This is an extremely difficult passage, and has been variously interpreted. What is the sin not unto death, for which we should ask, and life shall be given to him that commits it? And what is the sin unto death, for which we should not pray?

I shall note three of the chief opinions on this subject: -

1. It is supposed that there is here an allusion to a distinction in the Jewish law, where there was למיתה חטאה chattaah lemithah, "a sin unto death;" and למיתה לא חטאה chattaah lo lemithah, "a sin not unto death;" that is, 1. A sin, or transgression, to which the law had assigned the punishment of death; such as idolatry, incest, blasphemy, breach of the Sabbath, and the like. And 2. A sin not unto death, i.e. transgressions of ignorance, inadvertence, c., and such is, in their own nature, appear to be comparatively light and trivial. That such distinctions did exist in the Jewish synagogue both Schoettgen and Carpzovius have proved.

2. By the sin not unto death, for which intercession might be made, and unto death, for which prayer might not be made, we are to understand transgressions of the civil law of a particular place, some of which must be punished with death, according to the statutes, the crime admitting of no pardon: others might be punished with death, but the magistrate had the power of commuting the punishments, i.e. of changing death into banishment, c., for reasons that might appear to him satisfactory, or at the intercession of powerful friends. To intercede in the former case would be useless, because the law would not relax, therefore they need not pray for it but intercession in the latter case might be prevalent, therefore they might pray and if they did not, the person might suffer the punishment of death. This opinion, which has been advanced by Rosenmuller, intimates that men should feel for each other's distresses, and use their influence in behalf of the wretched, nor ever abandon the unfortunate but where the case is utterly hopeless.

3. The sin unto death means a case of transgression, particularly of grievous backsliding from the life and power of godliness, which God determines to punish with temporal death, while at the same time he extends mercy to the penitent soul. The disobedient prophet, 1 Kings 13:1, is, on this interpretation, a case in point: many others occur in the history of the Church, and of every religious community. The sin not unto death is any sin which God does not choose thus to punish. This view of the subject is that taken by the late Rev. J. Wesley, in a sermon entitled, A Call to Backsliders.-WORKS, vol ii. page 239.

I do not think the passage has any thing to do with what is termed the sin against the Holy Ghost; much less with the popish doctrine of purgatory; nor with sins committed before and after baptism, the former pardonable, the latter unpardonable, according to some of the fathers. Either of the last opinions (viz., 2 and 3) make a good sense; and the first (1) is not unlikely: the apostle may allude to some maxim or custom in the Jewish Church which is not now distinctly known. However, this we know, that any penitent may find mercy through Christ Jesus; for through him every kind of sin may be forgiven to man, except the sin against the Holy Ghost; which I have proved no man can now commit. See the note on Matthew 12:31; Matthew 12:39.
