Go on then; show your working.
Didn't Locke already do that in the
Two Treatises?
Anyhow, though I don't acknowledge any spiritual premises from the Bible, even I can see how one can reason from those premises to arrive, without undue difficulty, at the notion that slavery contravenes them.
One might reasonably conclude that slavery, especially chattel slavery of the sort we knew in the New World, violates the Golden Rule. If I love my neighbor as myself, and wish to do to him as I would have him do to me, should I consign him to slavery?
One might reasonably conclude that the state of slavery, which fundamentally reduces human persons to instruments of gain, is a dishonor to the natural dignity of rational creatures created in God’s image, and to God himself who asserted that whatever we do to one another, we do to him.
One might reasonably conclude that if “your body is the temple of the Holy Spirit which is in you, which you have of God, and you are not your own” having been “bought, and at a price” (
i.e. Jesus' sacrifice), then our ownership of and commerce in other human bodies is
a fortiori an affront and injustice to God.
One might reasonably conclude that slavery entails a denial of certain virtues praised in the Bible (
e.g. justice, charity, mercy, fraternity, humility) and an indulgence of corresponding vices that are condemned there.
One might reasonably conclude that accepting the Bible’s assertion of the spiritual and
a priori equality of members of the human race, who are “of one blood”, deprives us of a just basis for arguing that some of us are meant to be owned by others.
Noting the frequency with which the image of freedom is invoked as a blessing (“the liberty wherewith Christ hath made us free”; “the perfect law of liberty”; “the glorious liberty of the children of God”; etc.), one might reasonably conclude that – even assuming
arguendo that the images are figurative – their very use acknowledges personal liberty as a great good (and the unmerited suppression of which must be a great wrong).
But why bother to reinvent the wheel here? Arguing the the immorality of slavery from scriptural bases has been a feature of Western anti-slavery writing from St. Cyprian through Locke through the 19th-century American abolitionists.
