If the Old Testament is divinely inspired by God, even a little bit, then I do not understand how it can sanction and promote so many egregiously wrong ideas, such as slavery:
As for your male and female slaves whom you may have: you may buy male and female slaves from the nations that are round about you. You may also buy from among the strangers who sojourn with you and their families that are with you, who have been born in your land; and they may be your property. You may bequeath them to your sons after you, to inherit as a possession forever; you may make slaves of them, but over your brethren the people of Israel you shall not rule, one over another, with harshness. – Leviticus 25.44
How can a "good" book say such a bad thing. How can a modern day Christian, many of whom purport to believe in the bible as the divinely inspired and (to many) inerrant work of God reconcile these words with our modern opinions on slavery. These (and others) are the words which emboldened and succored southern slave owners up to and during the American Civil War; these are the words which kept the "coloreds" in their place, separate and unequal.
The bible advocates many ideas and policies which we have (thankfully) long ignored, including stoning people to death for things such as working on the sabbath. If this work is divinely inspired why do the faithful not follow it more closely? If this work is divinely inspired by an omniscient God, how could it become so quickly outdated?
