“A slave was, in Greek or Roman eyes, absolutely limited as to the consideration anyone (even a god) could show for him. Even if freed, he would always be treated as a social, civic, and spiritual inferior. A runaway had no right to any consideration at all. Deploying Christian ideas against Greco-Roman culture, Paul joyfully mocks the notion that any person placing himself in the hands of God can be limited or degraded in any way that matters. The letter must represent the most fun anyone ever had writing while incarcerated. The letter to Philemon may be the most explicit demonstration of how, more than anyone else, Paul created the Western individual human being, unconditionally precious to God and therefore entitled to the consideration of other human beings.”
