1 Timothy 6:3-6 "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; He is proud, knowing nothing, but doting about questions and strifes of words, whereof cometh envy, strife, railings, evil surmisings, Perverse disputings of men of corrupt minds, and destitute of the truth, supposing that gain is godliness: from such withdraw thyself. But godliness with contentment is great gain."
The reason why men’s minds are corrupt is because they do not stick to the truth as it is in Jesus: supposing that gain is godliness, making religion truckle to their secular interest. From such as these Timothy is warned to withdraw himself. Whoever teaches otherwise, and does not consent to these wholesome words, he is proud, knowing nothing; for pride and ignorance commonly go together. Paul sets a brand only on those who consent not to the words of our Lord Jesus Christ, and the doctrine which is according to godliness; they are proud, knowing nothing: other words more wholesome he knew not. We learn the sad effects of doting about questions and strifes of words; of such doting about questions comes envy, strife, evil surmisings, and perverse disputings; when men leave the wholesome words of our Lord Jesus Christ, they will never agree in other words, either of their own or other men’s invention, but will perpetually wrangle and quarrel about them; and this will produce envy, when they see the words of others preferred to those they have adopted for their own; and this will be attended with jealousies and suspicions of one another, called here evil surmisings; then they will proceed to perverse disputings. Such persons as are given to perverse disputings appear to be men of corrupt minds, and destitute of the truth; especially such as act in this manner for the sake of gain, which is all their godliness, supposing gain to be godliness, contrary to the apostle’s judgment, who reckoned godliness great gain. Good ministers and Christians will withdraw themselves from such. "Come out from among them, my people, and be ye separate,’’ says the Lord: from such withdraw thyself. —Matthew Henry (1662–1714)
