I don’t, but the various books in the Bible were written in specific times and contexts, often times when slavery was common. The bible puts limits on slavery, says at various places to release slaves after 7 years, to pay them, to treat them well.
One place in the NT that deals with slavery (and is pretty controversial because of that), is when Paul sends an escaped slave back to his master, with a letter to the master telling him to treat the slave as a brother, because they’re brothers in Christ, both children of God.
Paul was trying to spread Christianity in Greece, where slavery was very common, and outright condemning it would probably make a lot of Greeks reject it. There are a lot of places where you can see Paul being very pragmatic about stuff as long as it helps spread the Word. So I guess “here’s you’re slave, but remember he’s your brother” is his compromise with slavery.
There are a lot of Christians of many different varieties. None of the Christians I know would agree with conservative Americans.
