I think people often apply even the New Testament passages rather selectively. Consider Ephesians 6. We often hear the first part quoted to say that slavery is biblical.
But is there any form of slavery that works without threats? And where slaves and masters are seen as equal before God? This next sentence is usually left out.Slaves, obey your human masters with fear and trembling, in the sincerity of your heart, as you would Christ. Don’t work only while being watched, as people-pleasers, but as slaves of Christ, do God’s will from your heart. Serve with a good attitude, as to the Lord and not to people, knowing that whatever good each one does, slave or free, he will receive this back from the Lord.
I am really not sure whether Paul was asking Philemon to free his slave Onesimus, but he was certainly at least pleading that he would treat him as a dearly loved brother.And masters, treat your slaves the same way, without threatening them, because you know that both their Master and yours is in heaven, and there is no favoritism with him.
What are we to learn from this? How does this apply to modern slavery or slavery as practiced in the United States before the Civil War?For perhaps this is why he was separated from you for a brief time, so that you might get him back permanently, no longer as a slave, but more than a slave—as a dearly loved brother. He is especially so to me, but how much more to you, both in the flesh and in the Lord.
So if you consider me a partner, welcome him as you would me. And if he has wronged you in any way, or owes you anything, charge that to my account. I, Paul, write this with my own hand: I will repay it—not to mention to you that you owe me even your very self. Yes, brother, may I benefit from you in the Lord; refresh my heart in Christ. Since I am confident of your obedience, I am writing to you, knowing that you will do even more than I say.
