The slaves were sold into slavery by other africans, they weren't put into slavery by Americans. (there may be an exception to this but I don't know about that) Also, I am not trying to defend particular instances of slavery, I am just trying to make a point that when done properly, it is not unBiblical.
Ok, again, I have never excused the abuse of slavery but it seems that there are two different things that we are arguing here, I do not believe that a slave should be mistreated by the master and the master should treat the slave just as he would would like to be treated in the same situation. The master should feed the slave well. The master should provide good housing for the slave. The master should supply good clothes for the slave and the list goes on and on. In short, slavery is NOT free labor. It is actually a very worry free way of life if it is done properly...BTW.....I think the fact that we have been led to believe that it is always something evil is why we don't understand when the Bible talks of a "servant of Jesus Christ"
Is God unloving as our master? No He isn't. He is the great and Holy master.
I know see what you are getting at and I think that is where your problem lies, you are so used to the idea of "Uncle Tom's" cabin that you don't realize what slavery really is. What I am defending is one man owning the labor of another man in the exchange for the total care of that man. This is what the Bible allows. The Bible does NOT allow one man to take the labor of one man and not repay him in some form or fashion. We have this kind of thing all over today. The difference is that isn't isn't lifetime. There are many instances where a man doesn't own the product of his labor. He has agreed to trade his labor for whatever the contract setup requires.
I have read that a common form of slavery during the colonial period of North America was when a young man wanted to come to the new world but couldn't afford it he would become the slave of a wealthy business man for a certain period of time. The master of course owned the labor of that man for that period of time...anything he produced belonged to the master and that was agreed to by both parties.
Fast forward to the present. A few years ago I watched a movie about the early days of the computer industry and I thought it was interesting that Steve Wosniak who was an employee (which is IMO a very benevolent form of slavery) of Hewlett Packard couldn't market any inventions he made while he was employed there, why? Because under the contract, he did not OWN his labor, HP did. Now does that make HP a terrible place to work? Probably not. In Exchange HP had to pay whatever the contract required and I am sure that there were medical benefits as well but I am not sure to what extent.
Of course you may argue that this is all voluntary and that would be correct and that the topic at hand is involuntary.
The simple fact is, I am not a big fan of involuntary labor, however, the bottom line is that the Bible simply does not prohibit that and since it doesn't, I can't eithe. At that point, you have to take up your complaint with God or show me where I am wrong from the Bible which until this point you have failed to do.
