Does the Bible say that slavery is wrong? Yes, but not straight out.
The Bible has been used to argue both for and against slavery. A clear case of that was in America in the early 1800s. Just as with prohibition and abortion later on, many who opposed slavery did so for religious reasons.
Yet slave owners had their own choice Bible verses by which to defend their actions. But it was, in effect, a derailing tactic:
- Anyone who seriously reads the Bible knows it is not just a trick bag of verses. A battle of the verses is completely the wrong level at which to settle the issue.
- Despite their carefully chosen Bible verses, slave owners knew deep down that what they were doing was wrong from a Christian point of view. Why else their need to look down on black people?
Reading and understanding the Bible is something that takes a lifetime. I used to think the Bible was just a pack of lies, but that was before I read the whole thing for myself from end to end. It is too easy to take it the wrong way if you just read bits of it. The Bible has to be read in full. Not all of it is meant to be taken literally and there is often more then one layer of meaning.
Further, as a Catholic I do not believe in private interpretation. It is way too easy for people to read the Bible in a way that excuses their sins. I have seen that with my own eyes. In America you saw that in the 1800s with slave owners and you see it now with some homosexuals.
That does not mean I read the Bible with my brain turned off. Hardly. But what it does mean is that if I disagree with the Church over some point of doctrine because of my reading and understanding of the Bible, I assume the Church is way more likely to be right – it has been doing the Bible thing way longer than I have. It is like when you are 14 and you think you know more than your parents – well, the truth is, you do not. Your parents have lived much longer and so, in most cases, they are that much more likely to be right.
Many Catholic societies have practised owning slaves, owning people as property: Roman, Brazilian, Haitian, etc. But most have not. And, so far as I know, popes have never defended the practice and have often condemned it. But as with adultery and bad government, they are not out to save society but to save souls.
The Bible nowhere clearly condemns slavery, polygamy or infanticide and yet most Christians through most of history believed those things were wrong. Why? Because they go against the moral understanding of the world that the Christian Bible gives you. The best way to express it in a few words: We are all sinners yet we are all God’s children.
