Well, The bible says something about slavery. Hang on
*gets bible out*

1 Timothy 6:1
All those who are under the yoke of slavery must have unqualified respect for their masters, so that the name of God and our teaching is not brought into disrepute.

Tt 2:9
Slaves must be obedient to their masters in everything, and do what is wanted without argument.

Tt 2:10
And there must be no pilfering.

Tt 2:10
They must show complete honesty at all times...

Tt 2:10
...so that they are a credit in every way to the teaching of God our Saviour.

1 Peter 2:18
Slaves, you should obey your masters respectfully, not only those who are kind and reasonable but also those who are difficult to please.

1 Corinthians 7:21
Even if you have a chance of freedom...

1 Corinthians 7:21
...you should prefer to make full use of your condition as a slave.

I do hope this is relevant.
