I may not, strictly speaking, count myself one of your ‘flock’. Nevertheless, I thought I would write a response to your recent Encyclical Letter, Laudato Si’[1]. I do this for three reasons: first, because you have addressed this Encyclical not just to members of the Roman Catholic Church, but to ‘every living person on the planet’; second, because the issues you touch on in your Encyclical are so crucial to the wellbeing, hope and survival of our planet – as you put it, we need to ‘acknowledge the appeal, immensity and urgency of the challenge we face’; and finally, because I see, in the clear links you make between care for creation, social justice, and personal spirituality and lifestyle, a strong resonance with my own journey of discovery.
