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.

4. He is proud—literally, "wrapt in smoke"; filled with the fumes of self-conceit (1Ti 3:6) while "knowing nothing," namely, of the doctrine which is according to godliness (1Ti 6:3), though arrogating pre-eminent knowledge (1Ti 1:7).

doting about—literally, "sick about"; the opposite of "wholesome" (1Ti 6:3). Truth is not the center about which his investigations move, but mere word-strifes.

questions—of controversy.

strifes of words—rather than about realities (2Ti 2:14). These stand with them instead of "godliness" and "wholesome words" (1Ti 6:3; 1Ti 1:4; Tit 3:9).

evil surmisings—as to those who are of a different party from themselves.
