1 John 5:16

A sin which is not unto death That we may not cast away all hope of the salvation of those who sin, he shews that God does not so grievously punish their falls as to repudiate them. It hence follows that we ought to deem them brethren, since God retains them in the number of his children. For he denies that sins are to death, not only those by which the saints daily offend, but even when it happens that God’s wrath is grievously provoked by them. For as long as room for pardon is left, death does not wholly retain its dominion.

The Apostle, however, does not here distinguish between venial and mortal sin, as it was afterwards commonly done. For altogether foolish is that distinction which prevails under the Papacy. The Sorbons acknowledge that there is hardly a mortal sin, except there be the grossest baseness, such as may be, as it were, tangible. Thus in venial sins they think that there may be the greatest filth, if hidden in the soul. In short, they suppose that all the fruits of original sin, provided they appear not outwardly, are washed away by the slight sprinkling of holy water! And what wonder is it, since they regard not as blasphemous sins, doubts respecting God’s grace, or any lusts or evil desires, except they are consented to? If the soul of man be assailed by unbelief, if impatience tempts him to rage against God, whatever monstrous lusts may allure him, all these are to the Papists lighter than to be deemed sins, at least after baptism. It is then no wonder, that they make venial offenses of the greatest crimes; for they weigh them in their own balance and not in the balance of God.

But among the faithful this ought to be an indubitable truth, that whatever is contrary to God’s law is sin, and in its nature mortal; for where there is a transgression of the law, there is sin and death.

What, then, is the meaning of the Apostle? He denies that sins are mortal, which, though worthy of death, are yet not thus punished by God. He therefore does not estimate sins in themselves, but forms a judgment of them according to the paternal kindness of God, which pardons the guilt, where yet the fault is. In short, God does not give over to death those whom he has restored to life, though it depends not on them that they are not alienated from life.

There is a sin unto death I have already said that the sin to which there is no hope of pardon left, is thus called. But it may be asked, what this is; for it must be very atrocious, when God thus so severely punishes it. It may be gathered from the context, that it is not, as they say, a partial fall, or a transgression of a single commandment, but apostasy, by which men wholly alienate themselves from God. For the Apostle afterwards adds, that the children of God do not sin, that is, that they do not forsake God, and wholly surrender themselves to Satan, to be his slaves. Such a defection, it is no wonder that it is mortal; for God never thus deprives his own people of the grace of the Spirit; but they ever retain some spark of true religion. They must then be reprobate and given up to destruction, who thus fall away so as to have no fear of God.

Were any one to ask, whether the door of salvation is closed against their repentance; the answer is obvious, that as they are given up to a reprobate mind, and are destitute of the Holy Spirit, they cannot do anything else, than with obstinate minds, become worse and worse, and add sins to sins. Moreover, as the sin and blasphemy against the Spirit ever brings with it a defection of this kind, there is no doubt but that it is here pointed out.

But it may be asked again, by what evidences can we know that a man’s fall is fatal; for except the knowledge of this was certain, in vain would the Apostle have made this exception, that they were not to pray for a sin of this kind. It is then right to determine sometimes, whether the fallen is without hope, or whether there is still a place for a remedy. This, indeed, is what I allow, and what is evident beyond dispute from this passage; but as this very seldom happens, and as God sets before us the infinite riches of his grace, and bids us to be merciful according to his own example, we ought not rashly to conclude that any one has brought on himself the judgment of eternal death; on the contrary, love should dispose us to hope well. But if the impiety of some appear to us not otherwise than hopeless, as though the Lord pointed it out by the finger, we ought not to contend with the just judgment of God, or seek to be more merciful than he is.
