However Greece shared no such revulsions, most of the population owned slaves and those that didnt couldnt(not land owners). AND THIS TIME I CHECKED.
I was disputing your claim that America (as a nation) saw nothing wrong with slavery. You might have a point about slavery in ancient Greece, but I don't know, because I HAVEN'T CHECKED.
It could be that slavery isn't an "absolute morality", on the basis that there have been different models of slavery throughout history. During the time of Christ, slavery existed, and He didn't Speak out against it, because it was much different than slavery as we know it. They were "debtors" to their owners, working off what they owed until they settled their debt and were freed. They were permitted to own land, come & go, have families and even outside jobs. So "slavery" in its broad sense wouldn't be inherently wrong. Slavery as it existed in the early 1800's was.
