Human Trafficking, the Bible, and the Church

Human trafficking causes untold suffering to millions throughout the world. From a Christian perspective it should go without saying that we ought to work towards the eradication of this evil. The Bible, however, which all Christian traditions recognize as normative for faith and practice, reflects an era in which slavery was regarded as the norm. This raises a question: can it have anything to say to the church about human trafficking, or should it be discarded as irrelevant and anachronistic?
