Mankind has come up with some truths. One good example -- slavery is absolutely wrong.
Surely you can agree with that?
Sorry. We are talking about truth.
"...slavery is absolutely wrong."
Funny, this is not stated anywhere in the Bible. There are no commandments "Thou shall not purchase a human being" for example.
Of course, I teach Sunday School, and I have noticed the VAST majority of my fellow Christians refuse to discuss at length the implications of the book Philemon for example. OR a whole host of other verses which indicate God found Slavery to be an instrument of his will. For example, the Jews were as an entire tribe, slaves...; this was after Abraham was renamed from his original name, Abram if you recall...
So 'slavery' per se wasn't condemned. The Pharoah was not instructed to free all slaves.
Today, slavery is as much in play as ever, but now we are thoughtfully lie and call it 'human trafficking'. It is 'illegal'; sort of like Mary Jane is illegal. But folks don't talk very coherently about that either.
Btw, I'd be curious to any link that you would care to offer that explains exactly how you justify that 'slavery is absolutely wrong'. Who sez so? (Don't get me wrong, I wouldn't care to be owned or buy someone; I'm just curious how someone on your side of the fence defends this 'more')
