2 Timothy 2:17

"Let the wickedness of sinners be brought to nought." He who says this prayer is obviously a disciple of the evangelical precepts. He prays for those who treat him maliciously, asking that the wickedness of the sinners be circumscribed by a definite limit and boundary. Just as if someone, when praying for those who are suffering in body, would say, "Let the disease of those who are suffering come to an end." In order that the sin slowly creeping farther may not spread like cancer, since he loves his enemy and wishes to do good to those who hate him, and for this reason prays for those who treat him maliciously, he begs of God that the further outpouring of sin may cease and have definite bounds.

But these by all their words have attempted to do away with the Godhead of Christ, have made those seem righteous, since they have come nearer to Antichrist. Wherefore they have been excommunicated and anathematized by the Church. And indeed, although we grieve at the …

But if we consider what the apostles thought about heretics, we shall find that they, in all their epistles, execrated and detested the sacrilegious wickedness of heretics. For when they say that "their word creeps as a canker". Flee from such men as much as you can; avoid with a wholesome caution those who adhere to their mischievous contact. Their word doth eat as doth a cancer;. Also in the second to Timothy: "Their word doth creep as a canker."

From such men come those who, without divine appointment, set themselves over their rash associates, make themselves prelates without any lawful ordination and call themselves bishops though no one gives them a bishopric. The Holy Spirit portrays them in the Psalms "sitting in the seat of pestilence," plagues and blights to faith, snake-mouthed traitors, scheming to pervert truth, spewing deadly poisons from their pestiferous tongues. Their words "spread like a canker." Their teaching pours fatal venom into men's hearts and breasts.

"And shun profane novelties of speech." For they will not stop there. For when anything new has been introduced, it is ever producing innovations, and the error of him who has once left the safe harbor is infinite, and never stops. "For they will increase unto more ungodliness," he says, "And their word will eat as doth a canker." It is an evil not to be restrained, not curable by any medicine, it destroys the whole frame. He shows that novelty of doctrine is a disease, and worse than a disease. And here he implies that they are incorrigible, and that they erred not weakly but willfully.

He said well above: "they will advance still more in ungodliness." It would seem that the only evil consists in what they say about the resurrection. However, great consequences follow from this. For if the resurrection has already occurred, then judgment and recompense are also …

Their speech spreads like a canker. For heretics say true and useful things in the beginning; but after a while they vomit forth deadly doctrines. Hence he says, their speech spreads like a canker; from one spark comes a great fire, and from one deceitful …

And their word will eat as doth a cancer,.... Or "gangrene", which gnaws and feeds upon the flesh, inflames and mortifies as it goes, and spreads swiftly, and endangers the whole body; and is therefore to be speedily taken notice of, and stopped. It is better rendered "gangrene", as in the marginal reading, than "cancer". "The word "gangrene" is Greek (g), and is derived by some authors from the Paphlagonian "gangra", a goat; it being the character of a goat to browse the grass all around without shifting.

And their word - The word, or the discourses of those who love vain and idle disputations. Will eat as doth a canker - Margin, “gangrene.” This word - γάγγραινα gangraina - occurs nowhere else in the New Testament. It is derived from γραιω graiō, γραινω grainō, to devour, corrode,” and means “gangrene” or “mortification” - the death of a part, spreading, unless arrested, by degrees over the whole body. The words rendered “will eat,” mean “will have nutriment;” that is, will spread over and consume the healthful parts.

will eat--literally, "will have pasture." The consuming progress of mortification is the image. They pretend to give rich spiritual pasture to their disciples: the only pasture is that of a spiritual cancer feeding on their vitals. canker--a "cancer" or "gangrene." Hymenaeus--(See on 1Ti 1:20).

Their word will eat as doth a canker - Ὡς γαγγραινα· As a gangrene; i.e. as a mortification in the flesh, where the circulation is entirely stopped, and putrefaction takes place, which continues to corrupt all the circumjacent flesh, spreading more and more till death takes place, unless stopped by a timely and judicious application of medicine. Such is the influence of false doctrine; it fixes its mortal seed in the soul, which continues to corrupt and assimilate every thing to itself, till, if not prevented by a timely application of the word of life, under the direction of the heavenly Physician, it terminates in the bitter pains of an eternal death. To such a gangrene the apostle compares the corrupt doctrines of Hymeneus and Philetus.
