that slavery is the easiest moral question or that the bible got it wrong? the first one is my opinion. the second is that the bible doesn't condemn slavery, just gives you rules. For example...
Leviticus Chapter 25, verse 44:
Your male and female slaves are to come from the nations around you; from them you may buy slaves. You may also buy some of the temporary residents living among you and members of their clans born in your country, and they will become your property. You can will them to your children as inherited property and can make them slaves for life, but you must not rule over your fellow Israelites ruthlessly.
it's true slavery was different and accepted then. but ownership of human beings is
and it shows me that the morality it is advocating not modern enough and contradicts my beliefs that slavery is evil. compare it to the godless morality buddhists advocate. they tried to destroy the caste system and felt all living creatures were equal and we should have compassion for all of them. which one do you think is a stronger code of ethics?
