{5} If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness;

(5) He severely condemns and excommunicates or casts out of the Church as proud men, those who do not content themselves with Christ's doctrine, (that is to say, the doctrine of godliness) but weary both themselves and others, in vain questions (for all other things are vain), because they do not content themselves in Christ's doctrine. He condemns them as lying deceivers, because they savour or sound of nothing but vanity: as mad men, because they trouble themselves so much in matters of nothing: as evil plagues, because they cause great contentions, and corrupt men's minds and judgment. To be short, he condemns them as profane and wicked, because they abuse the precious name of godliness and religion, for the sake of wicked gain.

People's New Testament

6:3 If any man teacheth otherwise. Teach new doctrines or duties which differ from the doctrine of Christ. See 1Ti 1:3,4.

Wesley's Notes

6:3 If any teach otherwise - Than strict practical holiness in all Its branches. And consent not to sound words - Literally, healthful words; words that have no taint of falsehood, or tendency to encourage sin. And the doctrine which is after godliness - Exquisitely contrived to answer all the ends, and secure every interest, of real piety.

Jamieson-Fausset-Brown Bible Commentary

3. teach otherwise-than I desire thee to "teach" (1Ti 6:2). The Greek indicative implies, he puts not a merely supposed case, but one actually existing, 1Ti 1:3, "Every one who teaches otherwise," that is, who teaches heterodoxy.

consent not-Greek, "accede not to."

wholesome-"sound" (1Ti 1:10): opposed to the false teachers' words, unsound through profitless science and immorality.

words of our Lord Jesus Christ-Paul's inspired words are not merely his own, but are also Christ's words.

Matthew Henry's Concise Commentary

6:1-5 Christians were not to suppose that religious knowledge, or Christian privileges, gave them any right to despise heathen masters, or to disobey lawful commands, or to expose their faults to others. And such as enjoyed the privilege of living with believing masters, were not to withhold due respect and reverence, because they were equal in respect to religious privileges, but were to serve with double diligence and cheerfulness, because of their faith in Christ, and as partakers of his free salvation. We are not to consent to any words as wholesome, except the words of our Lord Jesus Christ; to these we must give unfeigned consent. Commonly those are most proud who know least; for they do not know themselves. Hence come envy, strife, railings, evil-surmisings, disputes that are all subtlety, and of no solidity, between men of corrupt and carnal minds, ignorant of the truth and its sanctifying power, and seeking their worldly advantage.
