The Bible and Human Trafficking. In Setting the Captives Free Marion Carson sets out to answer the question, What does the Bible say about human trafficking? Aimed at Christian anti-trafficking activists and church groups, the book offers an overview of the biblical material on slavery and the sex trade. Acknowledging that there is a difference between the biblical worldview and that of most Christians today with regard to slavery, it suggests that we can learn much from the Abolitionists of the eighteenth and nineteenth centuries. Following their example, it reads the biblical text through the lens of the law of love.
