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.

2. And—rather, "But." The opposition is between those Christian slaves under the yoke of heathen, and those that have believing masters (he does not use the phrase "under the yoke" in the latter case, for service under believers is not a yoke). Connect the following words thus, "Let them (the slaves) not, because they (the masters) are brethren (and so equals, masters and slaves alike being Christians), despise them (the masters)."

but rather, &c.—"but all the more (so much the more: with the greater good will) do them service because they (the masters) are faithful (that is, believers) and beloved who receive (in the mutual interchange of relative duties between master and servant; so the Greek) the benefit" (English Version violates Greek grammar). This latter clause is parallel to, "because they are brethren"; which proves that "they" refers to the masters, not the servants, as Tittmann takes it, explaining the verb in the common sense (Lu 1:54; Ac 20:35), "who sedulously labor for their (masters') benefit." The very term "benefit" delicately implies service done with the right motive, Christian "good will" (Eph 6:7). If the common sense of the Greek verb be urged, the sense must be, "Because they (the masters) are faithful and beloved who are sedulously intent on the benefiting" of their servants. But Porphyry [On Abstinence, 1.46] justifies the sense of the Greek verb given above, which also better accords with the context; for otherwise, the article "the," will have nothing in the preceding words to explain it, whereas in my explanation above "the benefit" will be that of the slaves' service.

These things teach—(1Ti 4:11; Tit 2:15).
