Titus 2:9
9Exhort servants to be in subjection to their own masters and to be well-pleasing in all things, not contradicting,
Paul speaks pastorally to Christians already in a first-century household as bondservants. Submissive to their own masters in everything, well-pleasing, not argumentative: Wesley heard “please them in all things—wherein it can be done without sin,” and “not answering again—though blamed unjustly.” The limit is sin; the counsel is costly respect.
Honor is aimed at adorning the doctrine (v. 10), not at baptizing the institution. It is first-century household counsel so that Christ is not blamed. Grace that saves also trains a holy witness in a hard setting.
Calvin is historically plain: Paul does not mean servants such as we have in the present day, but slaves bought with money and held as property. Report that fact without defending the yoke. The desire of pleasing, Calvin adds, must be limited to things which are proper.
God cares how the doctrine looks in a household already under that yoke. Obedience here is witness under providence, not a brief for slavery. The church’s first loyalty is the Savior named in the next verse; contempt and argument that make the gospel look rebellious would slander the Lord who bought them.
