Perry: I would prefer a third option: Free your slave and love him as your own dear brother. How refreshing it would be to have those words recorded in the NT. Instead, we read: "Ye masters, do the same things unto them ( their slaves ), forbearing threatening." ( Ephesians 6:9 )
I suspect that Paul's words are quite generous when compared to the prevailing first century view of how slaves should be treated, but they fall woefully short of what I would expect to find in a book inspired of a god of perfect love and justice. In a book of many, many prohibitions, not once do we read: Thou shalt not enslave.
