When it comes to slavery the bible, Christianity/Judaism, does not seem to have a problem with it. After all this isn't like it clearly and unequivocally states in the religion of JAINISM ... 'do not enslave people'.
A little New Testament on slavery. Ephesians 6:5 - Slaves, obey your earthly masters with deep respect and fear. Serve them sincerely as you would serve Christ. (Ephesians 6:5 NLT)
In the following parable, Jesus clearly approves of beating slaves even if they didn't know they were doing anything wrong.
Luke 12:47-48 - The servant will be severely punished, for though he knew his duty, he refused to do it. "But people who are not aware that they are doing wrong will be punished only lightly. Much is required from those to whom much is given, and much more is required from those to whom much more is given." (Luke 12:47-48 NLT)
And of course, a little Old Testament.
Leviticus 25:44-46 - However, you may purchase male or female slaves from among the foreigners who live among you. You may also purchase the children of such resident foreigners, including those who have been born in your land. You may treat them as your property, passing them on to your children as a permanent inheritance. You may treat your slaves like this, but the people of Israel, your relatives, must never be treated this way. (Leviticus 25:44-46 NLT)
Exodus 21:7-11 - When a man sells his daughter as a slave, she will not be freed at the end of six years as the men are. If she does not please the man who bought her, he may allow her to be bought back again. But he is not allowed to sell her to foreigners, since he is the one who broke the contract with her. And if the slave girl's owner arranges for her to marry his son, he may no longer treat her as a slave girl, but he must treat her as his daughter. If he himself marries her and then takes another wife, he may not reduce her food or clothing or fail to sleep with her as his wife. If he fails in any of these three ways, she may leave as a free woman without making any payment. (Exodus 21:7-11 NLT)
It has been argued by some 'believers' old testament precepts do not apply but Jesus states in many places in the new testament that old testament rules and precepts must be honored. Perhaps then a good museum of slavery begins in this most honored text. Yes? Say amen! Ahhhhhmen!!!!
