You seem to suggest in Biblical times that slavery was only a concoction of the Jews or Christians. It was the worldwide accepted form of getting work done by the young and strong in a world with very few options beyond manual labor. People made war on other groups and took prisoners who they made slaves. The Church starting in Jerusalem in A.D. 33 didn't magically end all of that. It was the system that people were born into, whether slave or master, and it's all they knew. Often people who were masters were conquered by others who in turn made those masters slaves. Jesus brought a better way to live, but it took time for that to filter into the world. The book of Philemon was a recognition of the reality of the world Christians lived in. And if the world had never advanced, still required heavy manual labor for everything, you can bet the rich and powerful would be using their armies to obtain slaves. That's the reality that you don't want to accept.You’re really trying to hang your hat on slavery was just a metaphor thing. No slavery was not just a metaphor, in the Bible, sure there were passage that spoke about in that way, but those are not the ones I’m pointing out. I’m pointing out the whole that other person literally owns you like property slavery that the Bible promoted and told slaves to go along with, no matter how bad.
