{15} Else what shall they do which are baptized {o} for the dead, if the dead rise not at all? why are they then baptized for the dead?

(15) The fifth argument taken of the end of baptism, that is, because those who are baptized, are baptized for dead: that is to say, that they may have a remedy against death, because baptism is a token of regeneration.

(o) They that are baptized to this end and purpose, that death may be put out in them, or to rise again from the dead, of which baptism is a seal.

People's New Testament

15:29 Else what shall they do who are baptized for the dead? Paul again returns to the argument for the resurrection. This passage is difficult, and has received almost as many interpretations as there have been commentators. Some have held that there was a custom of baptizing living persons for the benefit of persons who had died without baptism. Had that custom existed, Paul would have rebuked it. It did arise afterwards, as an abuse from the misinterpretation of this passage, among the followers of Cerinthis, and, in our times, of Joseph Smith. I will try to make clear its meaning: (1) All the Corinthians were baptized (Ac 18:8). (2) Their baptism was a planting in the likeness of the burial of Christ, and in the likeness of his resurrection (Ro 6:4,5). They were in, and raised from, a watery tomb. (3) Their baptism in the likeness of the death and resurrection of Christ was in hope of their own resurrection from the dead through Christ's resurrection. ( Huper Nekroon, for, or on account of the dead, with the exception of resurrection from the dead.) But if Christ has not risen, and the dead rise not, this memorial and emblematic burial has no meaning. Why, then, are they baptized for the dead ? that is, for the sake of their own resurrection from the dead. This interpretation harmonizes better with Paul's argument than any I have seen.

Wesley's Notes

15:29 Who are baptized for the dead - Perhaps baptized in hope of blessings to be received after they are numbered with the dead. Or, baptized in the room of the dead - Of them that are just fallen in the cause of Christ: like soldiers who advance in the room of their companions that fell just before their face.

Scofield Reference Notes

Margin dead

i.e. who, through the introductory rite of baptism, are taking the places in the ranks left vacant by Christians who have died.

Jamieson-Fausset-Brown Bible Commentary

29. Else-if there be no resurrection.

what shall they do?-How wretched is their lot!

they . which are baptized for the dead-third person; a class distinct from that in which the apostle places himself, "we" (1Co 15:30); first person. Alford thinks there is an allusion to a practice at Corinth of baptizing a living person in behalf of a friend who died unbaptized; thus Paul, without giving the least sanction to the practice, uses an ad hominem argument from it against its practicers, some of whom, though using it, denied the resurrection: "What account can they give of their practice; why are they at the trouble of it, if the dead rise not?" [So Jesus used an ad hominem argument, Mt 12:27]. But if so, it is strange there is no direct censure of it. Some Marcionites adopted the practice at a later period, probably from taking this passage, as Alford does; but, generally, it was unknown in the Church. Bengel translates, "over (immediately upon) the dead," that is, who will be gathered to the dead immediately after baptism. Compare Job 17:1, "the graves are ready for me." The price they get for their trouble is, that they should be gathered to the dead for ever (1Co 15:13, 16). Many in the ancient Church put off baptism till near death. This seems the better view; though there may have been some rites of symbolical baptism at Corinth, now unknown, perhaps grounded on Jesus' words (Mt 20:22, 23), which Paul here alludes to. The best punctuation is, "If the dead rise not at all, why are they then baptized for them" (so the oldest manuscripts read the last words, instead of "for the dead")?

Matthew Henry's Concise Commentary

15:20-34 All that are by faith united to Christ, are by his resurrection assured of their own. As through the sin of the first Adam, all men became mortal, because all had from him the same sinful nature, so, through the resurrection of Christ, shall all who are made to partake of the Spirit, and the spiritual nature, revive, and live for ever. There will be an order in the resurrection. Christ himself has been the first-fruits; at his coming, his redeemed people will be raised before others; at the last the wicked will rise also. Then will be the end of this present state of things. Would we triumph in that solemn and important season, we must now submit to his rule, accept his salvation, and live to his glory. Then shall we rejoice in the completion of his undertaking, that God may receive the whole glory of our salvation, that we may for ever serve him, and enjoy his favour. What shall those do, who are baptized for the dead, if the dead rise not at all? Perhaps baptism is used here in a figure, for afflictions, sufferings, and martyrdom, as Mt 20:22,23. What is, or will become of those who have suffered many and great injuries, and have even lost their lives, for this doctrine of the resurrection, if the dead rise not at all? Whatever the meaning may be, doubtless the apostle's argument was understood by the Corinthians. And it is as plain to us that Christianity would be a foolish profession, if it proposed advantage to themselves by their faithfulness to God; and to have our fruit to holiness, that our end may be everlasting life. But we must not live like beasts, as we do not die like them. It must be ignorance of God that leads any to disbelieve the resurrection and future life. Those who own a God and a providence, and observe how unequal things are in the present life, how frequently the best men fare worst, cannot doubt as to an after-state, where every thing will be set to rights. Let us not be joined with ungodly men; but warn all around us, especially children and young persons, to shun them as a pestilence. Let us awake to righteousness, and not sin.
