Apostolic Constitutions, 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.”

“But as to servants, what can we say more than that the slave bring a good will to his master, with the fear of God, although he be impious and wicked, but yet not to yield any compliance as to his worship? And let the master love his servant, although he be his superior. Let him consider wherein they are equal, even as he is a man. And let him that has a believing master love him both as his master, and as of the same faith, and as a father, but still with the preservation of his authority as his master: "not as an eye-servant, but as a lover of his master; as knowing that God will recompense to him for his subjection." In like manner, let a master who has a believing servant love him as a son or as a brother, on account of their communion in the faith, but still preserving the difference of a servant.”
