But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned.
I'm curious because I stared at it until I was blue in the face, and nothing about slavery leaped out at me. I assume your reference to Romans is equally a smokescreen, since you didn't quote a verse, and I scanned it quickly without finding anything regarding "chattel" slavery or "bondservant" slavery or plain old vanilla slavery.
Here, by the way, is a fairly comprehensive list of the Old Testament verses that support slavery. Here's from the New. Notice the explicit use of the word "slavery" in the KJV. Also notice some of the more delicate injunctions the lord lays on his chosen people regarding these "bondsmen" and "maidservants" as you so delicately put it. Like legalized rape, and forced circumcision, or the titheing of virgin Midianite slaves captured in war and reserved for the priesthood.
As far as the website goes, it does not make roman slavery akin to a vacation in the bahamas. That is a dishonest mischaracterization. But that is not surprising coming from an intellectually dishonest person like you.
Posting bible verses about slavery is woefully insufficient to satisfy the burden of proof that is on you. Since context is everything and you have zero understanding of the context, and since you have made a judgment on the matter before you have the facts about OT/NT slavery, you are only succeeding in demonstrating your unmitigated bias.
You do not understand the application of 1Cor 2:14 for the precise reason that the verse itself gives - you are a natural man who has no capability of understanding truths that are spiritually discerned. Actually, that verse excludes the possibility of your understanding scripture in your present heart state. It's ironic isn't it that you can't even understand the verse that explains why you can't understand it.
