Anna Marina said: "Jehovah would never approve that which is harmful to those who love him and their fellow man.."
So let the mythical YHWH be judged out of his own mouth. Get your bible and read - (2 Samuel 12:10-18 ESV)
"10 Now therefore the sword shall never depart from your house, because you have despised me and have taken the wife of Uriah the Hittite to be your wife.’ 11 Thus says the Lord, ‘Behold, I will raise up evil against you out of your own house. And I will take your wives before your eyes and give them to your neighbor, and he shall lie with your wives in the sight of this sun. 12 For you did it secretly, gbut I will do this thing before all Israel and before the sun.’ ” 13 hDavid said to Nathan, i“I have sinned against the Lord.” And Nathan said to David, j“The Lord also has put away your sin; you shall not die. 14 Nevertheless, because by this deed you have utterly kscorned the Lord,2 the child who is born to you shall die.”"
So David sinned, but will YHWH punish guilty David. NO! old YHWH decides( without even asking David's wives whether they consented to being raped) to punish David's wives, by letting them be raped publicly. Was that an example of YHWHS morals? And, I have not even touched on YHWH's actions concerning the subsequent baby, which surely must count as an act of murder. And did you also note David's actions? During the child's sickness, David acts repentedly, but as soon as the child is dead, David acts normally again. That's barely human.
And can YHWH defend himself against charges that he permitted slavery? Let's see?
On the second issue raised, slavery, most ancient 'cultures,' practised slavery. The economies of nations across Eurasia were slave powered economies. Aristotle (greek philosopher) even argued in his "Politics" that some humans were 'natural' slaves. He further argued that a slave was a "piece of property," and owning a slave was like owning a tool. So you're likely thinking at this point, what's all that got to do with the bible?
The reason you wont find "Jesus" saying 'free the slaves,' is that firstly, from the beginning the Israelites were portrayed in the biblical stories as using war prisoners as slaves, and even selling each other into slavery.
first century CE, the Jews had (Since conquered by Alexander the Great) had become thoroughly hellenised and would have easily seen a 'slave' as an item of property. In fact, during the next few hundred years, the Jewish Talmud set out rules for slaves, and Jewish traders continued for centuries to buy and sell slaves.
So maybe your not seeing the world as Jesus saw the world. He likely thought of slavery as 'natural' - just as Aristotle thought it was natural. (Aristotle does give his reasons for his perspective)
But did that make it OK? It may be true that christian's later spoke against slavery, but it took a long time for churches to act against slavery. So long in fact, that there seems no reason to believe that churches in general were guided by either divine law or divine inspiration to oppose slavery
