{7} Servants, be obedient to them that are your masters {8} according to the flesh, with {d} fear and trembling, in singleness of your heart, as unto Christ;

(7) Now he descends to the third part of a family, that is, to the duty both of the masters and of the servants. And he shows that the duty of servants consists in a hearty love and reverence for their masters.

(8) He moderates the sharpness of service, in that they are spiritually free even though they are servants, and yet that spiritual freedom does not take away physical service: insomuch that they cannot be Christ's, unless they serve their masters willingly and faithfully, as much as they may with clear conscience.

(d) With careful reverence: for slavish fear is not allowable, much less in Christian servants.

People's New Testament

6:5 Servants. The term does not refer so much to hired servants, as slaves, of whom there were many millions in the Roman Empire at that time. These were of all races, prisoners taken in war, or their children. Christianity did not violently destroy this relation, but regulated, mitigated and undermined it by introducing a new element into human life which would destroy it.

Masters according to the flesh. Earthly masters whose dominion will go no farther than this world.

With fear and trembling. Not for fear of punishment, but for fear that the service is not done right.

In singleness of your heart, as unto Christ. Christ will see and reward your fidelity to duty, even if an earthly master does not.

Wesley's Notes

6:5 Your masters according to the flesh - According to the present state of things: afterward the servant is free from his master. With fear and trembling - A proverbial expression, implying the utmost care and diligence. In singleness of heart - With a single eye to the providence and will of God.

Jamieson-Fausset-Brown Bible Commentary

5. Servants-literally, "slaves."

masters according to the flesh-in contrast to your true and heavenly Master (Eph 6:4). A consolatory him that the mastership to which they were subject, was but for a time [Chrysostom]; and that their real liberty was still their own (1Co 7:22).

fear and trembling-not slavish terror, but (See on [2374]1Co 2:3; 2Co 7:15) an anxious eagerness to do your duty, and a fear of displeasing, as great as is produced in the ordinary slave by "threatenings" (Eph 6:9).

singleness-without double-mindedness, or "eye service" (Eph 6:6), which seeks to please outwardly, without the sincere desire to make the master's interest at all times the first consideration (1Ch 29:17; Mt 6:22, 23; Lu 11:34). "Simplicity."

Matthew Henry's Concise Commentary

6:5-9 The duty of servants is summed up in one word, obedience. The servants of old were generally slaves. The apostles were to teach servants and masters their duties, in doing which evils would be lessened, till slavery should be rooted out by the influence of Christianity. Servants are to reverence those over them. They are to be sincere; not pretending obedience when they mean to disobey, but serving faithfully. And they must serve their masters not only when their master's eye is upon them; but must be strict in the discharge of their duty, when he is absent and out of the way. Steady regard to the Lord Jesus Christ will make men faithful and sincere in every station, not grudgingly or by constraint, but from a principle of love to the masters and their concerns. This makes service easy to them, pleasing to their masters, and acceptable to the Lord Christ. God will reward even the meanest drudgery done from a sense of duty, and with a view to glorify him. Here is the duty of masters. Act after the same manner. Be just to servants, as you expect they should be to you; show the like good-will and concern for them, and be careful herein to approve yourselves to God. Be not tyrannical and overbearing. You have a Master to obey, and you and they are but fellow-servants in respect to Christ Jesus. If masters and servants would consider their duties to God, and the account they must shortly give to him, they would be more mindful of their duty to each other, and thus families would be more orderly and happy.
