I must admit that I have not yet read through Pope Francis' encyclical on climate change, Laudato Si, but fortunately Martin Marty has. In this week's edition of Sightings Marty takes note of both the negative responses, which decry the Pope's analysis of our situation in the name of unbridled free markets, what he terms an unholy holy war. Marty notes however that Francis' message is similar to or in the vein of a prophetic word found in scripture, which he remembers Bonhoeffer defining as "hope projected backwards." What he finds here then is a call to hope, and the good news is that over time words of support for Francis' message of joy and hope have emerged. May we also find hope in those efforts emerging to deal with the damaging effects of climate change.
