Ambrosiaster, on Col 3:22

“Servants, obey in all things your masters according to the flesh, not serving to the eye, as pleasing men, but in simplicity of heart, fearing God.”

“Let not earthly masters be arrogant, presuming authority, but rather temper and restrain their spirits, so that, with due consideration for the human race, they may recognize that God is the creator of all, not only of servants and free men, but of all freemen. But this has been made possible by the injustice of the world, so that while one invades the boundaries of another, then free men are led captive; hence they were called "captives" by the ancients, as they were seized by the hand. Here the condition and position even now appear, some are redeemed, others remain as slaves. But in the sight of God, this servant is held who has sinned (John VIII, 34). Finally, the servant of Cham heard the cause of sin: Cursed be the child of Canaan, he shall be the servant of servants to his brothers (Gen. IX, 25). To this sentiment the ancients agreed, so as to define that all wise men are free, but all foolish men are slaves; because the wise man abstains from sins, so that he may be free, who follows what is right; but the servant who submits himself to sin through the imprudence of foolishness. And so Cham, because of his foolishness, who foolishly burned his father's nakedness, was called a servant. He showed therefore to the lords, that they are not truly lords, but as if through an image; for they are lords of bodies, not of souls. For only the Lord, and the author of invisible things, God, rules over both bodies and souls; so that considering these things, they may demand just services from them: such as they themselves also desire to be demanded from the common Lord.”
