Who, concerning the truth have erred, saying that the resurrection is already past After having said that they had departed from "the truth," he specifies their error, which consisted in this, that they gave out that "the resurrection was already past." In doing this, they undoubtedly contrived a sort of allegorical resurrection, which has also been attempted in this age by some filthy dogs. By this trick Satan overthrows that fundamental article of our faith concerning the resurrection of the flesh. Being an old and worthless dream, and being so severely condemned by Paul, it ought to give us the less uneasiness. But when we learn that, from the very beginning of the gospel, the faith of some was subverted, such an example ought to excite us to diligence, that we may seize an early opportunity of driving away from ourselves and others so dangerous a plague; for, in consequence of the strong inclination of men to vanity, there is no absurdity so monstrous that there shall not be some men who shall lend their ear to it.

Who concerning the truth have erred - To what extent they had erred is unknown. Paul mentions only one point - that pertaining to the resurrection; but says that this was like a gangrene. It would certainly, unless checked, destroy all the other doctrines of religion. No man can safely hold a single error, any more than he can safely have one part of his body in a state of mortification.
Saying that the resurrection is past already - It is not known in what form they held this opinion. It may have been, as Augustine supposes, that they taught that there was no resurrection but that which occurs in the soul when it is recovered from the death of sin, and made to live anew. Or it may be that they held that those who had died had experienced all the resurrection which they ever would, by passing into another state, and receiving at death a spiritual body fitted to their mode of being in the heavenly world. Whatever was the form of the opinion, the apostle regarded it as a most dangerous error, for just views of the resurrection undoubtedly lie at the foundation of correct apprehensions of the Christian system; compare the notes at 1-Corinthians 15:12-19.
And overthrow the faith of some - That is, on this point, and as would appear on all the correlative subjects of Christian belief; compare 1-Timothy 1:19-20.

Who concerning the truth have erred - They had the truth, but erred or wandered from it, saying the resurrection was already past, and thus denying the resurrection of the body, and, by consequence, future rewards and punishments; and this necessarily sapped the foundation of all religion: and thus the gangrene had, in reference to their unhappy votaries, a rapid and unchecked operation.

Who concerning the truth have erred,.... That is, the two persons just mentioned; they fell from the truth, wandered and departed from it; they did not keep to the Scriptures of truth, but deviated from them; they missed that mark, and went astray into gross errors and mistakes; rejected the Gospel, the word of truth, in general, and particularly in
saying, that the resurrection is past already; and no other is to be expected; or that there was no future resurrection of the dead: their error was, as some think, that there is no other resurrection than that of parents in their children, who, though they die, live in their posterity; or than the resurrection of Christ, and of the saints, that rose at the same time; or rather, that there is no other resurrection than the spiritual one, or regeneration, which is a quickening of dead sinners, or the resurrection of them from the death of sin, to a life of grace; which seems to be the truest account of their principle, seeing this is what has been received and propagated by others since; though some have thought that they gave into the Palingenesia of the Pythagoreans, who supposed that when men die, their souls go into other bodies; and that these men imagined, that this is all the resurrection that will be: and others have been of opinion, that their notion was, that whereas the deliverance of the Jews out of the Babylonish captivity is signified by a resurrection of them, in Ezekiel 37:1 that this is the resurrection they meant was past, and no other to be looked for; but that which has been fixed upon seems to be the truest account:
and overthrow the faith of some; the Ethiopic version reads, "of many"; that is, of nominal professors of religion; not of true believers, for true faith cannot be overthrown. Hence it follows,

erred--Greek, "missed the aim" (see 1-Timothy 6:21).
is past already--has already taken place. The beginnings of the subsequent Gnostic heresy already existed. They "wrested" (2-Peter 3:16) Paul's own words (Romans 6:4; Ephesians 2:6; Colossians 2:12) "to their own destruction," as though the resurrection was merely the spiritual raising of souls from the death of sin. Compare 1-Corinthians 15:12, where he shows all our hopes of future glory rest on the literal reality of the resurrection. To believe it past (as the Seleucians or Hermians did, according to AUGUSTINE [Epistles, 119.55, To Januarius, 4]), is to deny it in its true sense.
overthrow--trying to subvert "the foundation" on which alone faith can rest secure (2-Timothy 2:19; compare Titus 1:11).

Saying the resurrection is already past - Perhaps asserting that it is only the spiritual passing from death unto life.
