Here’s the issue about that though. The Bible doesn’t have a single syllable condemning slavery. It just wasn’t part of the social structure of the millennia to do so. Instead, there are rules and laws governing slavery and how to do slavery better. I don’t doubt that Christians contributed to the abolition of slavery, but that’s not a very high bar when everybody is a Christian, regardless of their thoughts. How can one be so confident that it wasn’t Christianity and the enlightenment or Christianity and gospel music or something else? What specifically in Christianity made abolition more likely? From what I understand, enlightenment principles as well as the slave trade becoming unprofitable ended up stopping the slave trade
