Titus 2:10

10Not thievish but shewing all good faith He censures two vices that are common among servants, petulant replies, and a propensity to steal. (246) The comedies are full of instances of excessively ready talk, by which servants cheat their masters. Nor was it without reason that an exchange of names took place in ancient times, by which “servant “and “thief “became convertible terms. Thus prudence requires that we make our instructions apply to the morals of each individual.

Byfaith he means fidelity to their masters; and therefore, to shew all faith is to act faithfully, without using fraud or doing injury, in transacting the affairs of their masters.

That they may adorn the doctrine of God our Savior in all things This ought to be a very sharp spur of exhortation to us, when we learn that our becoming conduct adorns the doctrine of God, which, at the same time, is a mirror of his glory. And, indeed, we see that this usually happens; as, on the other hand, our wicked life brings disgrace upon it; for men commonly judge of us from our works. But this circumstance ought also to be observed, that God deigns to receive an “ornament” from shaves, whose condition was so low and mean that they were wont to be scarcely accounted men; for he does not mean “servants,” such as we have in the present day, but slaves, (247) who were bought with money, and held as property, like oxen or horses. And if the life of those men is an ornament to the Christian name, much more let those who are in honor take care that they do not stain it by their baseness.
