This is one of the more common objections raised against the moral authority of Scripture. But the objection often rests on a critical failure to distinguish between permission, regulation, and moral endorsement.
Does God’s regulation of a practice necessarily imply His approval of it? Does the existence of slavery in the biblical world mean Scripture endorses slavery as a moral ideal?
These are legitimate questions that deserve careful examination in their historical, theological, and biblical contexts.
Before judging what the Bible teaches, we ought to understand what it actually says.
I encourage you to watch this thoughtful examination of a difficult subject. Truth can withstand scrutiny.
