Now, for all its failings and its perversions over the last 2,000 years—and as much as every exponent of this faith has attempted to dodge this idea—it is unarguably the central tenet of Christianity: that everybody is equal in God's eyes. So you cannot, as a Christian, walk away from Africa. America will be judged by God if, in its plenty, it crosses the road from 23 million people suffering from HIV, the leprosy of the day.
What's up on trial here is Christianity itself. You cannot walk away from this and call yourself a Christian and sit in power. Distance does not decide who is your brother and who is not. The church is going to have to become the conscience of the free market if it's to have any meaning in this world—and stop being its apologist.
