Yes, God did say that in Lev. It also says in Joshua and elswhere that the Hebrews were to massacre certain people.
Yes, slavery is just one of the many evil things your God commands.
Does that mean that it is O.K for me to go out and buy someone or to go on a murder spree? No, and both for the same reason.
Because you have a moral sense independent of your religious belief.
God knows the inmost heart. If there are a people that God said should be killed, then it was because he had already been working on their hearts, but He who knows the hearts of men judged them to be too far gone. Thus they could be killed or owned.
Let me get this. Your new argument is that God thinks all non-Hebrews are so evil that it's morally justified to kill or own them? Seriously? That's your moral position? Because remember, you may slaves from among foreigners and their descendants.
The same reason that made what happened in the past okay is the same reason murder and slavery are wrong now.
It was right then but wrong now? Is slavery ever right?
Only God knows the heart. We cannot judge who deserves death or punishment.
It has nothing to do with punishment. God allows you to own any foreigner as a slave. God also commands you to kill anyone who lives in the land He gave you, including babies. Are you arguing that the babies were evil and deserved capital punishment? Is killing a baby ever morally justified?
God no longer speaks to us in the way he spoke to the OT prophets.
Maybe because we've made moral progress?
We are on our own, and so have only his word(as it applies to the present) and our own judgements on which to relly. And by both I can say slavery is wrong.
If God's words say it's right, how can you construe them to mean it's wrong? Does all of the Bible mean the exact opposite of what it says, or only the parts you don't like?
