Don't you have a job and debt to the bank?
"Slavery" has negative associations because man has been an animal towards his fellow man and trading and treating slaves like they're animals.
God does not think that's okay.
Have you not read your Bible?
Slavery - owning people as property - is condoned from Genesis to Revelation, listed in commandments 3(4) and 9(10), and supported by Jesus himself. God specifies that black people (Cushites) are to be slaves when he institutes slavery in Genesis 9.
Yes, Hebrew slaves were treated "better" - there were two parallel sets of laws for Hebrew and non-Hebrew slaves (like Jim Crow laws).
Non-Hebrew slaves were treated like, well, slaves.
For instance, God tells us that we are free to beat our slaves bloody, as much as we want, as long as they survive for at least a day afterward. Ex 21:21-
“Anyone who beats their male or female slave with a rod must be punished if the slave dies as a direct result, but they are not to be punished if the slave recovers after a day or two, since the slave is their property.
Jesus himself talks about beating slaves, without any hint of disapproval, such as in Luke 12.
This is why slavery flourished while Christianity ruled the world for 1500 years, and was only opposed after enlightenment ideas that opposed scripture took hold in the 1700s.
It's true that slavery is wrong - but that fact does not give us liberty to re-write our scriptures or our history to change what we don't like.
In Christ-
Papias
