'Laudato Si' is an encyclical that in effect identifies the Holistic Order of Life in Nature as Primary Church. So, it is appropriate for us humans, the self-reflective life of evolved Nature, to understand that Pope Francis' encyclical could just as truthfully have begun with the words:  "Ecclesiae Vita est Naturalis Sacramentum Ordinis".
'Following through with Vatican Two' we logically come to the sense that Nature is Church Universal in real time. http://www.secondenlightenment.org/Following%20Through%20with%20Vatican%20Two.pdf
