The Moral Hazard of Slavery

Father Casey's unilateral condemnation of slavery gets awkward because the Bible regulates slavery. St. Paul even told Christians to be kind to their slaves instead of just commanding Christians to release their slaves. It makes more sense to see slavery as a moral hazard that can be justified in very limited cases, like how the Bible tolerated ancient debt slavery. While not wrong in principle, this means we as a society should move away from slavery as much as possible.
