For the many of us – clergy and laypeople, academics and plain citizens, in the U.S. and throughout the world – who for decades have been saying that the environmental crisis calls for a religious perspective and an activist religious response Pope Francis’ bold words are a wonderfully welcome addition. At least three things give those words special weight: first, as the years pass the reality of both global warming in particular and the other dimensions of the crisis (including the vast scale of pollution, species loss, and environmental illness) have become increasingly clear. Second, Pope Francis has established himself as a humble, intelligent, and authentic spiritual leader. If political conservatives resent his critique of capitalism, and cultural conservatives wish he would condemn homosexuals, an awful lot of other people (Catholic or not) see him as a man trying to live up to the traditional Christian virtues of love, forgiveness, and humility. Third, and perhaps most important: Francis is clearly and unambiguously (for the most part, at least, skirting population control) calling a spade a spade: he rejects consumerism and unfettered capitalism, anthropocentrism and turning the earth into “an immense pile of filth.”
