Capitalism and Christianity are strange bedfellows. That’s not to say it can’t happen harmoniously with God’s will. Do you believe the bible any the less because generally to get a personal copy you have to go to a bookstore and buy it? Or would you do so in earlier days because you’d have to recompense a scribe for the scroll? Perhaps the openest thing to do would be to put it up on the web under a copyleft license (to assure its integrity), but if he’s got a family to look after maybe it was manna from heaven.
