If Pope Francis continues to sound relevant to Catholic and non-Catholic alike, and is able to see off the still powerful conservative forces in the Church before he steps down or dies - a big if as he is 78 after all - then he could act as a catalyst for social change and help the World find a way to deal with the challenges it faces from global warming to growing inequality.
Neither Friends of the Earth nor Pope Francis are anti-business. Laudato si isn't calling for an end to capitalism; for everything to re-nationalised. But, as the encyclical says 'The environment is one of those goods that cannot be adequately safeguarded or promoted by market forces.' Amen to that and ditto in the case of inequality.
