How about these which I think more honestly get to the point of the matter.
Were you a slave when you were called? Don't let it trouble you--although if you can gain your freedom, do so. For he who was a slave when he was called by the Lord is the Lord's freedman; similarly, he who was a free man when he was called is Christ's slave. You were bought at a price; do not become slaves of men.
1Cor7:21-23
You gladly put up with fools since you are so wise! In fact, you even put up with anyone who enslaves you or exploits you or takes advantage of you or pushes himself forward or slaps you in the face. To my shame I admit that we were too weak for that!
2 Cor 11:19-21
Yet not even Titus, who was with me, was compelled to be circumcised, even though he was a Greek. This matter arose because some false brothers had infiltrated our ranks to spy on the freedom we have in Christ Jesus and to make us slaves. We did not give in to them for a moment, so that the truth of the gospel might remain with you.
Gal 2:3-5
And what should be the clincher . . .
for all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus.If you belong to Christ, then you are Abraham's seed, and heirs according to the promise.
Galations 3:27-29
Saying the Bible establishes or encourages slavery or sexism is like saying our Constitution establishes slavery or sexism. The evils existed before the code. The code eventually ended -- or strongly mitigated -- the evils.
"Yet not even Titus, who was with me, was compelled to be circumcised, even though he was a Greek. This matter arose because some false brothers had infiltrated our ranks to spy on the freedom we have in Christ Jesus and to make us slaves. We did not give in to them for a moment, so that the truth of the gospel might remain with you. Gal 2:3-5"
The freedom and slavery talked about in that verse relate to the freedom from and slavery to the law (of Moses : the ten commandments and the multitude added by the jews) not being a slave or freeman as related to being owned by another human.
Christ fulfilled the law and therfore freed us from having to obey the letter of the law. What God wants is not for us to obey the law (since no man can possibly obey all the law, that was the point) but to have a relationship with god the father and god the son and then the holy spirit will abide within us and make us want to do what god wants, instead of us trying to fight our sin nature that we are unable to resist.
